CRP’s PTFE and PFA lined products are supplied to many different industry sectors and processes, whilst mainly they are used to convey very corrosive substances the other properties of lined piping like being non stick and high purity can find our piping being specified into a wide range of applications. Here are some examples of our customers.


CRP supply equipment to all the main Pharmaceutical companies in the UK. Large scale project supply has seen the completion of several pharmaceutical manufacturing plants with all the lined piping and valves being supplied by CRP both in the UK and abroad. Our lined piping provides universal plant application.


There are hundreds of derivatives of petrochemicals that can be manufactured from petroleum. Some of the additives used are very corrosive and toxic, our PTFE lined piping is used successfully to convey these products.

Biodiesel Production

In the manufacture of biodiesel a strong base – typically sodium hydroxide is used as a catalyst to help with the reaction, PTFE lined pipe and valves are used to convey this highly corrosive chemical and we have helped to complete several plants.

Crop Science

The production of biocides, fungicides, herbicides and insecticide involves the use of highly corrosive chemicals, CRP have supplied large amounts of PTFE lined piping and valves to these manufacturers.

Ink / Toner Manufacturers

The manufacture of toners for inkjet and laser printers is very complex involving the use of highly corrosive chemicals, PTFE lined pipe is the cost effective solution to convey these.


Most large scale projects are managed by contractors and design houses, we work very closely with these to keep costs to a minimum, we are able to offer many value adding, money saving services to ensure projects run smoothly.

Chemical Manufacturing

Many chemical manufacturers use CRP lined piping products in their facilities, feed stock chemicals such as bromine, sulphuric acid, nitric acid etc are all corrosive and require the use of corrosion resistant piping – PTFE lined piping is the ideal solution.

Fine Chemical Manufacturers

Manufacturing of chemical substances for use in manufacturing drugs, commonly called APIs (active pharmaceutical ingredients) often involves the use of highly corrosive substances. PTFE lined pipe is widely used to convey such substances, it is FDA approved and is easily cleanable.

Food Manufacturers

PTFE lined pipe has excellent non stick properties, which can be used to solve process problems with very viscous food stuffs such as margarines etc.

Drinks Manufacturers

Phosphoric, acidic, ascorbic and other acids are commonly used in soft drink production,. As well as these, caustic solutions are used to clean the piping between production runs. Some piping components are in contact with very high concentrations of these chemicals leading to premature corrosion of the stainless steel piping used, we have supplied PTFE lined components to replace these failing lines to safely convey these chemicals.

Process Plant Manufacturers

CRP can help with the design and specification of components required in the manufacture of process skid units, process packages etc utilising PTFE and PFA lined products. Our piping and valves are often used around specialist components such as filter assemblies, dryers, scrubbers etc.

Aerospace Manufacturers

Alloys used in aircraft manufacture sometimes need aggressive cleaning using acidic and caustic solutions often is large plating tanks, our lined pipe and valves help with the safe containment of these cleaning fluids.

Water Treatment

Chemicals such as Chlorine and Sodium hypochlorite are extensively used in water treatment plants. Whilst these are diluted significantly with the water, the pure chemical holding and injection / mixing lines are subject to corrosion. Our products are supplied to RO plants, marine applications as well as many water treatment works.

Power Stations

Fossil fuelled power stations can suffer a variety of corrosion issues, the steam and cooling water requires treatments which can corrode steel piping and valves. By using PTFE lined pipe and valves on these applications prevents the corrosion of the equipment.

Cleaning and Detergent Product Manufacturers

Chemicals used in cleaner and detergents can derive from very corrosive and toxic chemicals, our PTFE lined piping has replaced many polypropylene and other thermoplastic piping systems which have prematurely failed on these applications.

Flavour and Fragrance Enhancers

Additives used in the manufacture of these specialist food stuffs can encounter corrosion problems with some of the chemical reactions used, CRP supply lined piping and valves to these manufacturers to overcome these issues.

Flowmeter Manufacturers

CRP supplies OEM fluoropolymer lining services to global scale flowmeter manufacturers. Fluoropolymers have excellent insulating characteristics as well as corrosive and non stick properties making them an ideal choice for this specialist market.

Plastics Manufacturers

Some of the base chemicals used in plastic manufacture are highly corrosive, for example the manufacture of PVC involves the handling of vinyl chloride, chloroethane and hydrogen chloride all very corrosive and toxic substances, the use of PTFE lined piping is widespread in these industries.

Tanker Manufacturers

Our Durco range of plug valves are often specified to be fitted to ISO road tankers due to their excellent bubble tight shut off.

Precious Metal Refiners

Precious metals such as platinum, palladium, rhodium etc are recovered from used catalytic convertors. Very strong acids are used to remove the carbon steel materials and refine the product, CRP has provided lined piping and valves to these processors.

Paint Manufacturers

Biocides are added to paints to prevent fungal growth, however these neat biocides can be quite corrosive, CRP supply PTFE lined piping and injection nozzles into these processes to paint manufacturers.


Sulfuric acid is commonly uses in precious metal mining to remove impurities, our piping and sampling systems have been supplied onto this sector.
