Quality

The highest quality & safety mark on this planet as laid down by the European Communion is the CE mark.

What is CE mark?

If you go under pressure directives, the CE certified factory with the plant
MEANS THAT ALL THE PLANTS AND MACHINERY HAVE
GLOBAL CONFIRMITY ASSESMENT, PARA 2 ARTICLE 10,97/23/EC

SEE THE CE CERTIFICATE ATTACHED.

The CE mark a quality-mark. First, it refers to the safety & to the quality of a product. Second, most quality markings are voluntary opposite to the CE marking, which is mandatory for the products it applies to. CE indicates conformity with mandatory European safety requirements. European conformity is certified by following clear and understandable procedures, the so-called
‘conformity assessment procedures’.

Why CE marking?

The European CE certification procedure has been mainly set up to:

1. Harmonize all varying national regulations for consumer and industrial products in European Member States, so that the Single Market is encouraged.
2. Bring about cost savings for producers.
3. Enhance the safety of products.
4. Supply public bodies with a uniform procedure that can be checked.

Formerly, product requirements and test procedures were set by the Member States of the EU. This meant that, for example, companies that wanted to sell their products on the European market sometimes had to deal with more than ten different technical requirements or procedures for just one product. The existence of all the different national legislation was contrary to the aim of the European Union in realizing one Single Market, in which there would be a free circulation of goods (as well as a free circulation of persons, services and capital).

I AM SURE THAT YOUR RIGHTS ARE SECURED IN THE BEST POSSIBLE WAY.

Thanking you & assuring the best of our services and co-operation all the time.

WHAT IS CE MARKING (CE MARK)?

CE Marking is the symbol as shown on the top of this page. The letters "CE" are the abbreviation of French phrase "Conformité Européene" which literally means "European Conformity". The term initially used was "EC Mark" and it was officially replaced by "CE Marking" in the Directive 93/68/EEC in 1993. "CE Marking" is now used in all EU official documents.

"CE Mark" is also in use, but it is NOT the official term. For instance, in the Directive 2007/47/ec, of 5 September 2007, amending the directives 90/385/eec, 93/42/eec & 98/8/ec, the term CE Marking appears 9 times whereas CE Mark appears nowhere in the entire 35-page document.

1. CE Marking on a product is a manufacturer's declaration that the product complies with the essential requirements of the relevant European health, safety and environmental protection legislation, in practice by many of the so called Product Directives.*

*Product Directives contains the "essential requirements" and/or "performance levels" and"Harmonized Standards" to which the products must conform. Harmonized Standards are the technical specifications (European Standards or Harmonization Documents) which are established by several European standards agencies (CEN, CENELEC, etc.) CEN stands for European Committee for Standardization. CENELEC stands for European Committee for Electro technical Standardization.

2. CE Marking on a product indicates to governmental officials that the product may be legally placed on the market in their country.
3. CE Marking on a product ensures the free movement of the product within the EFTA & European Union (EU) single market (total 28 countries)
4. CE Marking on a product permits the withdrawal of the non-conforming products by customs and enforcement/vigilance authorities.

Along with more directives' becoming effective, more and more products are required to bear the CE Marking for gaining access to the EFTA & European Union market. However, many non-EU exporters are still unaware of or unsure about this fact and its impact on their business.

WHAT IS CRYOGENIC AIR SEPARATION PLANT

Dear customers
An oxygen nitrogen air separation plant is a very sophisticated piece of cryogenic engineering.

What is cryogenics?

In physics, cryogenics is the study of the production of very low temperature (below −150 °C, −238 °F or 123 K) and the behavior of materials at those temperatures. A person who studies elements under extremely cold temperature is called a cryogenicist. Rather than the relative temperature scales of Celsius and Fahrenheit, cryogenicists use the absolute temperature
scales. These are Kelvin (SI units) or Rankine scale (Imperial & US units).

1. Distillation Column

Source Linde Gas Division

The separation of air into its constituent parts at high purity requires a cryogenic distillation process. To achieve the low distillation temperatures a modern Air Separation Unit requires a refrigeration cycle, and the cold equipment has to be kept within an insulated enclosure (commonly called a "cold box"). The cooling of the gases requires a large amount of energy to
drive an air compressor to make this refrigeration cycle work. The air also has to be "clean" enough for cryogenic distillation, since water and carbon dioxide as well as other minor constituents of air can freeze in the cryogenic equipment.

2. Plate-Fin Heat Exchangers

Plate-Fin Heat Exchanger Systems

Prof Robin Smith Manchester University Nobel Prize Winner has something to say!

Abstract

Heat transfer operations can be intensified through the use of compact heat exchangers. In particular, plate-fin heat exchangers offer many advantages over conventional designs. True counter-flow allows temperature differences as low as 1oC. Also, the volume required is of the order of one quarter that required for conventional heat exchanger designs. This project has
developed the first truly systematic methods for the design and optimization of heat exchanger networks involving plate-fin heat exchangers.

Project description

Compact heat exchangers, such as plate-fin multi-stream devices, are well established in some sectors of the process industries. However, their application has been largely restricted to low temperature (sub-ambient) processes. Plate-fin multi-stream heat exchangers offer many advantages over conventional designs. True counter-flow allows temperature differences as low as 1oC. Also, the volume required is of the order of one quarter that required for conventional heat exchanger designs.

When using multi-stream plate fin heat exchangers, the overall problem has two broad aspects. First is the design of the plate-fin heat exchanger itself. We must decide which type of fin we will use for the surface, the dimensions of the heat exchanger, its volume and its pressure drop. This is in itself a challenging problem. Second, we need to determine the heat exchanger network design. We must decide on the number of units, the intermediate headers, stream matching arrangements, the total volume and the total pressure drop. This is also a challenging problem. What is even more challenging is that these two aspects interact strongly with each other. No systematic methods are currently available for the design of heat exchanger networks involving plate-fin multi-stream heat exchangers.

This project has developed the first truly systematic methods for the design and optimization of heat exchanger networks involving plate-fin multi-stream heat exchangers. The design procedures have been automated.

The procedures have been tested on a number of industrial problems and found to bring significant reductions in the volume of the equipment (volumes typically halved), together with a significant reduction in the complexity of the design.

3. Air Compressor

Atmospheric air is pre-filtered (to remove dust), and compressed to a pressure typically between 5 and 10 bar. Since the compressor heats up the air, it is cooled again in a heat exchanger to ambient temperatures. This can also achieve the removal of some ambient moisture.

4. Purification Unit

The process air is generally passed through a molecular sieve bed, which removes any remaining water vapor, as well as carbon dioxide, which would freeze in the cryogenic equipment. The molecular sieve is often designed to remove any gaseous hydrocarbons from the air, since these can be a problem in the subsequent air distillation.

5. Cooling & Distillation

Process air is passed through an integrated heat exchanger (usually a plate fin heat exchanger) and cooled against product (and waste) cryogenic streams. The air is then cool enough to be distilled in a distillation column. The formation of liquid air in the cryogenic equipment requires some refrigeration and liquid is usually formed by Joule Thomson expansion of air across a valve or through an Expander, (a reverse compressor). The air is distilled in at least one and often two distillation columns, depending on the products required. Cryogenic air separation units are built to provide one or both of nitrogen and oxygen although argon is also often produced. Liquid nitrogen "LIN", Liquid oxygen "LOX" and liquid argon can be produced if sufficient refrigeration is provided for in the design. Finally the product gases are warmed against the incoming air to ambient temperatures.

6. Turbo Expansion

A turbo expander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial flow turbine through which a high pressure gas is expanded to produce work that is often used to drive a compressor.

Because work is extracted from the expanding high pressure gas, the expansion is approximated by an isentropic process (i.e., a constant entropy process) and the low pressure exhaust gas from the turbine is at a very low temperature, sometimes as low as −90 °C or less.

Turbo expanders are very widely used as sources of refrigeration in industrial processes such as the extraction of ethane and natural gas liquids (NGLs) from natural gas,[4] the liquefaction of gases (such as oxygen, nitrogen, helium, argon and krypton) and other low-temperature processes.

Throttling process redirects here. For the regulation of computing resources, see throttling process (computing).

In thermodynamics, the Joule–Thomson effect or Joule–Kelvin effect or Kelvin–Joule effect describes the temperature change of a gas or liquid when it is forced through a valve or porous plug while kept insulated so that no heat is exchanged with the environment. This procedure is called a throttling process or Joule–Thomson process. At room temperature, all gases except hydrogen, helium and neon cool upon expansion by the Joule–Thomson process.

The effect is named for James Prescott Joule and William Thomson, 1st Baron Kelvin who discovered it in 1852 following earlier work by Joule on Joule expansion, in which a gas undergoes free expansion in a vacuum.

Description

The adiabatic (no heat exchanged) expansion of a gas may be carried out in a number of ways. The change in temperature experienced by the gas during expansion depends not only on the initial and final pressure, but also on the manner in which the expansion is carried out.

• If the expansion process is reversible, meaning that the gas is in thermodynamic equilibrium at all times, it is called an isentropic expansion. In this scenario, the gas does positive work during the expansion, and its temperature decreases.
  
  
• In a free expansion, on the other hand, the gas does no work and absorbs no heat, so the internal energy is conserved. Expanded in this manner, the temperature of an ideal gas would remain constant, but the temperature of a real gas may either increase or decrease, depending on the initial temperature and pressure.
  
• The method of expansion discussed in this article, in which a gas or liquid at pressure P1 flows into a region of lower pressure P2 via a valve or porous plug under steady state conditions and without change in kinetic energy, is called the Joule –Thomson process. During this process, enthalpy remains unchanged (see a proof below).

A throttling process proceeds along a constant-enthalpy line in the direction of decreasing pressure, which means that the process occurs from left to right on a T-P diagram. As we proceed along a constant-enthalpy line from high enough pressures the temperature increases, until the inversion temperature. Then as the fluid continues its expansion the temperature drops. If we do this for several constant enthalpies and join the inversion points a line called the inversion line is obtained. this line intersects the T-axis at some temperature, named the maximum inversion temperature. For hydrogen this temperature is -68°. In Vapourcompression refrigeration we need to throttle the gas and cool it at the same time. This poses a problem for substances whose maximum inversion temperature is well below room temperature. Thus hydrogen must be cooled below its inversion temperature if any cooling is achieved by throttling.

Physical mechanism

Product supply and storage

The air gases are sometimes supplied by pipeline to large industrial users adjacent to or nearby to the production plant or stored as liquid. Unless a viable pipeline system exists, long distance transportation of products is usually done as a liquid product for large quantities or as dewar flasks or gas cylinders for small quantities.

In addition to oxygen, nitrogen and argon; rarely other gas products may be produced - the only viable sources of neon, krypton and xenon are from the distillation of air.

It is a process equipment consisting of pressure vessels subjected to extreme low temperatures and pressures, Where lot of engineering experience and technological backup is required.

I sincerely hope that buyers all over the world will take this explosion seriously and study the deep implications of buying nonstandard Chinese products and non-branded Indian or any other where designs and engineering are not established.

Please buy only CE approved products.

I sincerely sympathize with the buyers who have been lured by Chinese manufacturers and local non branded manufacturers by offering cheap deals and selling nonstandard oxygen nitrogen plant machineries.

NON-DESTRUCTIVE TESTING (NDT CE) TECHNIQUES TO PREVENT FAILURE

To improve manufacturing quality and product reliability, components and structures are regularly inspected for discontinuities, defects or faults which may reduce their structural integrity leading to failure. Among the material testing methods developed for inspection purposes, Non-destructive testing (NDT CE) techniques present the advantages of leaving the components undamaged after inspection.

Inspection facilities are equipped with modern NDT equipment, approved practices, procedures, qualified and certified NDT CE Level I, II, technicians and in-house ASNT NDT III certified professionals, materials testing experts, welding inspection and quality control
personnel.

Why NDT?

NDT can be used to:

1. Weeding out defective raw materials /components at the incoming stage itself instead of accepting and paying for it.
2. Detect defects that may occur during the manufacturing process before spending time and money on further processing of the defective materials
3. Improve manufacturing techniques by inspecting the product during processing operations to maintain uniform quality and standard.
4. Detecting discontinuities at final stages of manufacturing to improve product reliability and safety during operation
5. In-service inspection to detect service induced flaws Ensure prevention of accidents and promote safety for workers and equipment during over hauling and maintenance
6. Enhance the reputation of manufacturer as producer of quality product

Works on the principles of differential absorption of radiation, radiography is used to detect internal flaws in castings and welds. Additional advantage with Radiography is the availability of permanent record for future reference. Our company has experienced Level 1, 2, 3 professionals to carry out the tests and interpretations accurately.

5. Visual Testing

Visual testing (VT) is one of the oldest and most widely used NDE methods to derive a multitude of useful information from a variety of material characteristics and properties. Visual examination is used in all stages of manufacturing and fabrication as a means of verifying conformance to standards and ensuring the quality levels are met and maintained in the final product. A great deal of specialized equipments, certified inspectors as per ASNT recommended practice SNT-TC-1A, technicians and NDT level III's exists for this purpose and can provide ASME 'U' stamp consultation on NDT.
