Materials Introduction CRP complement the lined piping with associated products that follow the PTFE or PFA lined theme. These include: Key Lining Choices Application – PFA lined Ball, Plug and Butterfly Valves for the UK market – PFA lined Swing Check and Poppet Check Valves Most applications requiring lined pipe and fittings Applications with known permeant chemicals Applications for high purity Applications requiring management of static discharge; typically non-conducting solvents – PFA lined Control Valves – PFA lined Strainers – PFA lined and unlined Tubular Sight Glasses and Level Gauges...

Design Philosophy Manufacturing It is important to understand that CRP manufacture their own products in their manufacturing facility based just north of Manchester in the UK. CRP is unusual in the UK as the only direct manufacturer of the product from raw fluoropolymer through to the finished product. This gives the business great advantages of logistical control of delivery lead-times and due date adherence. It also means that we are fully in control of our own manufacturing processes and quality and can provide complete product traceability. Process Expertise CRP has been around for much of...

Welded Pipe Spool Fixed-Rotating Flanges This spool construction has a welded slip on flange at one end and a welded stub end and loose backing flange at the other to provide a rotating flange.

Spacer Type 1 Tapered Type 1 spacers can also be provided tapered to a set angle or dimension on opposite sides of a flange face. This can provide a change in the angle of the pipework, useful for starting or ending falls. Spacers are used as small gap fillers in a piping system, where the space is too small for a conventional pipe spool or the opportunity does not arise to make a spool to the precise length required. The type Spacer Type 1 Tapered 2 spacer is a wafer fitting and should be specified for gap filling from the shortest size available for the relevant nominal bore – being a more...

Spacers are used as small gap fillers in a piping system, where the space is too small for a conventional pipe spool or the opportunity does not arise to make a spool to the precise length required. Type 3 spacers are manufactured from pipe spool piping, but have stub ends in place of flanges as conventional bolting would not fit in the distance. They should be specified in preference to Type 2 spacers as soon as the gap meets the minimum length. They have an outside diameter sized to fit snugly inside the bolt circle of the adjacent parts. 1 - Please note liner thicknesses are based on Virgin...

90o Elbow Rotating Flanges ØB This design of elbow has two rotating flanges captured behind stub ends. This design makes installation easy and provides versatility. The elbow design is ideal as a stock item for maintenance requirements. 90º Elbow Rotating Flanges The 45° elbow of course provides a 45° change of direction. These are generally lined in PTFE. Note that a 1 inch 45° elbow does not have through holes in the flanges, they are tapped ½ inch UNC Construction Codes Code HiPerFlon PTFE Liner Thickness Nominal1 Construction Codes Cast Steel Cast Steel Fabricated Steel Fabricated Steel 1...

Equal Tee Rotating Flanges Equal tees provide a robust pipeline branch of the same nominal bore as the main pipeline itself. They are used for making additions or merging separate flows. Tees are manufactured to ASME B16.5 class 150 dimensions, but variations on standard dimensions are available on request. They can be manufactured with either fixed flanges, rotating flanges or a mix. Fixed flange products are the most economical solution. The most popular tee sizes are supplied with a high integrity investment cast steel body and wetted parts lined with a heavy wall PFA, providing superior permeation...
