PTFE lined Pipes

Our PTFE lined pipe series starts from 25mm to 300mm Diameter and up to 3000mm in lengths. Our standard pipes are with one end fix flange and one end loose flange. We can supply both end fix flanges and loose flanges on specific requirements.

Jacketed pipes with various metals (fabricated steel, cast ductile iron, 304 and 316 stainless steel, etc.) are available. It is also possible to vary Metal Pipe thickness (S10, S20, S40, S80, etc.) on a special order basis.

Standard flange thickness is as per AISI standards. Flanges 150 #, 300# and DIN rotating flanges are available in a variety of materials.

All our standard pipes are supplied with vent holes for leakage detection during operation.

PTFE lined Elbows

Elbows are manufactured using 90°, 60°, 45° or 30°. Other types of angles are available on request. All elbows are supplied always with a fix flanges and loose flanges are on request only.

Jacked elbows with various metal options are available for special application on request.
We offer a wide variety of PTFE lined elbows. All PTFE lined elbows are lined with paste extruded PTFE liners flared each end over the flange faces similar to our pipe spools.

Our standard elbows are manufactured to ASME B16.5 class 150 dimensions. We can also offer elbows to DIN dimensions, all our elbows can be supplied with a stainless steel body for use on clean rooms etc.Long Radius 45 Degree and 90 Degree Elbows on special request which is ideal for use with in slurry lines to keep pressure drops to a minimum.

PTFE lined spacers

Solid PTFE or Lined spacers are available for connecting flanges at short distance.

For lengths which are just a little too short to be a pipe spool we offer PTFE lined pipe with welded stub ends, this is effectively a pipe spool without flanges being manufactured from lined steel pipe with 2 off welded stub ends as used on a pipe spool with PTFE paste extruded liner flared each end.

For spacers too short where we cannot weld 2 stub ends, we manufacture the steel from a solid billet machined to the correct length and then lined with PTFE extruded tube flared each end.

For the shortest lengths of spacer we supply a solid ring of PTFE. Note that these do not have the support of a steel housing they can only safely be used for short lengths.

FEP/PFA lined Tee / cross & Instrument Tees

FEP/PFA lined Tee; Cross & Instrument Tees are generally manufactured to ASME B16.5 class 150 dimensions. We can also offer fittings to DIN dimensions.

Fixed flanges are used as a standard. Fixed and Loose flange connections are also availableon request.

Instrument Tees to be used for temperature, pressure indicators And/or for samplings. The bodies are welded steel. (Cast iron on request)

PTFE/FEP Lined Reducer & Reducing flanges

Reducers are mainly two types, concentric reducers & Eccentric reducers, our standard reducers. Generally cast steel with PTFE/FEP lining with flanged end connections.

Our standard reducers insure free flow of fluids for horizontal and vertical lines equally.

FEP/PFA lined reducing flanges can be grouped into different types, the configuration is based on the closeness of the small bore bolt holes to the large bore bolt holes. Each type is designed so that they do not clash and that the nuts can be fitted successfully.

PTFE lined Dip Pipes/Feed Pipes

Our PTFE lined steel dip pipes and spargers are manufactured to the highest standards in the industry. All units are given extreme stress tests to validate their integrity and ensure long life.

A broad range of options are available to meet your process requirements. These include diverters (to direct/gas flow away or towards vessel walls), Extended flares (to eliminate additional reducing flanges), spargers, Anti-Siphon Holes etc.


Since the early part of the decade, fluorochemical treatments for food contact applications have changed substantially, such that new products that are free of PFOA, longer-length PFCAs and their precursors (at or above detection limits) have supplanted the traditional grades available in the past. These new fluorochemicals are available in a large range of specific chemistries, and their breadth and depth are often confusing to the paper processor. However, the manufacturing methodologies have not changed much, with many of these current products exhibiting the same system compatibility issues as in the past.

In this study we provide a short review of the current available technologies, and also examine two different fluorochemicals as representatives of a number of products available in the current paper market. The objective of the study will be to illustrate the role of pH and charge chemistry on the ultimate performance of the new materials, such that paper processors may derive maximum benefits in terms of oil and grease resistance.

Making the Most of the New Fluorochemicals

In simplest terms, a major factor in making the new fluorochemicals work properly in paper applications is ensuring that there is a sufficient amount of the product being used for the application. Also, the fluorochemicals must go where we wish for them to go – e.g. the cellulose fiber in the treated paper. These two items seem obvious, but they are the main cause of problems with any new-breed fluorochemical system.

In the ensuing examples (Parts 1 – 3; below), three different new fluorochemicals are examined for performance under various conditions present during paper-making and external sizing. Each is here given a pseudonym, and all are polymeric materials making use of C6 technology (i.e. six perfluoronated carbon atoms in the active functional group). Fluorochemical #1 (abbreviated as FC #1) is cationic in its chemistry and mildly acidic in pH. Fluorochemicals #2 and #3 (FC #2, #3) are also cationic and acidic in chemistry. (see Table 1 in the APPENDIX for details) Together they provide a small sampling of the PFOA-free fluorochemicals* available for paper and packaging applications.

Plastics Industries

When we refer to plastics we usually mean polymers, since plastic is a condition or state of a material. (metals when heated can be plastic: can be moulded into shapes).
Types of plastics
Natural Plastics

  • Amber.
  • Animal Horn.
  • Natural rubber.
  • Shellac.

Modified natural plastics

  • Cellulose (made from cotton fibre and wood pulp).
  • Casein (made from cows milk).

Synthetic plastics
Produced entirely by human-controlled chemical processes:

  • By-products from the production of gas from coal.
  • By-products from the distillation of crude oil.


The word polymer comes from the Greek word for “many parts”. They are the result of joining a number of basic units known as “monomers”. Within the polymer molecule there is a repeated unit known as a “mer”. Mers are the building blocks of all plastics.

Classification of Polymers

Polymers can be classified under two main headings:

Can be heated and formed, then re-heated and re-formed repeatedly. The shape of the polymer molecules is generally linear, or slightly branched, allowing them to flow under pressure when heated above the effective melting point. All of the bonds within the polymer molecule are primary bonds which are very strong chemical bonds. The bonds between adjacent molecules are secondary bonds or Van der Waals forces they have relatively weak forces of attraction. They can be weakened even further by raising the temperature, this is why they flow under pressure.


Undergo a chemical as well as a phase change when they are heated. Their molecules form a three-dimensional cross-linked network, this is known as curing. Once they are heated and formed they can not be reprocessed – the three- dimensional molecules can not be made to flow under pressure when heated. (normally condensation polymerisation). Primary bonding occurs

Additives used in plastics

Polymers are often combined with other materials to give them certain desired properties. They include:
Used to improve polymers mechanical properties, can also reduce the amount of polymer present to make them cheaper.
Wood flour – gives strength and good mouldability.
Cloth fibre – gives good impact strength.
‘whiskers’ of metal – gives very high strength.
Mica – good electrical insulating properties.


Added to improve flexibility, the plasticiser separates the molecules and reduces the forces of attraction between them.

Stabilisers and antioxidants
Help to prevent the degrading effects of heat, ultraviolet light and oxidation on the polymer.

Colour pigments
Give the plastic the desired colour.

Flame retardants
Used when plastic is to be used as a building material or for clothing or furniture.


Added to make it easier to mould. Waxes and soaps are examples of lubricants. Usually very little is used as they affect the engineering properties of the moulded material.

Recycling Plastics

Most thermoplastic polymers can be recycled – that is converted from their initial use as a consumer, business, or industrial product, back into a raw material from which some other product can be manufactured. Recycled materials are often classified as Post-Industrial and Post-Consumer. Post-Industrial includes such things as manufacturing scrap, containers and packaging. Post-Consumer is basically any product, container, packaging, etc. that has passed through the hands of a consumer, e.g. plastics bags, beverage containers, carpeting, home appliances, toys, etc.

Thermosetting polymers can only be recycled for use as an inert filler (something to take up space) in another material.

The keys to effective recycling are:

  • an efficient infrastructure for collecting used materials
  • ease of separation and low levels of contamination
  • an established market for reprocessing/reusing the materials

What Is Fluoro Polymers

A Fluoro polymer is an organic compound consisting of fluorine and carbon atoms but can also contain oxygen or hydrogen. The atoms are held together by bonds to form monomers such as tetra fluorethylene (TFE). When the monomer is polymerized they form into long chains to which TFE becomes polytetrafluoroethylene (PTFE). Fluoro polymers can be either fully fluorinated or partially fluorinated.


Fluoropolymers are distinguished particularly by their high thermal, chemical and weather resistance, excellent surface properties (especially oil and water repellency) and optical properties (low refractive index). Accordingly, fluoropolymers are indispensable materials in a wide variety of industries





Since fluoropolymers came on the market in 1930s, they have been applied as coating materials in order to achieve those characteristics mentioned above on the surfaces of various substrates. Typical examples include coatings made from aqueous dispersion poly tetra fluoroethylene(PTFE), etrafluoroethylene/hexafluoroethylene copolymers (FEP), and tetra fluoroethylene/perfluoroalkyl vinyl ether copolymers (PFA) for non-stick and anti-corrosion applications. However, those fluoropolymers are not necessarily suitable for use as coating materials due to their poor solubility in conventional organic solvents, the requirement of baking temperatures greater than 200℃ and weak adhesion to substrates.

Among the well-known fluoropolymers, only polyvinylidene fluoride (PVdF) has been used for coatings as an organic dispersion, mainly for architectural applications due to its outstanding weather ability.

A unique solvent soluble fluoroolefinvinyl ether co-polymer (abbreviated as FEVE co-polymer, with the trade name “LUMIFLON”) was developed in 1982 by Asahi Glass. This co-polymer consists of alternating sequences of fluoroolefin and several specific vinyl ether units (Fig.1), and is completely amorphous. This alternating sequence is responsible for extremely high weather resistance of the resultant paint finishes. Combinations of several kinds of vinyl ether co-monomers provide the polymer with other useful physical properties, such as solubility in organic solvents, pigment compatibility , cross-linking sites and impart good adhesion, hardness and flexibility to the coating. The major reason for the use of FEVE co-polymers as raw materials for coatings is their excellent weather resistance. The hydroxyl group in the FEVE polymer functions as the cross-linking site with blocked isocyanates or melamine resins for heat cured coatings, and with aliphatic polyisocyanates for on-site coatings.

As Asia is celebrating 21st century with potential market growth and industrial expansion, India is one of the team player who really countable when considering the rivals in that growth hierarchy,  having big supplied to the Industry, PTFE products are one of the key factor for industries like, Chemical, Pharma and various others who have their row material in the liquid form.
