Static Dissipating Liner Pipe Fittings ETFE Rotated Liner Pipe Spools
Our piping systems can be supplied with virgin unpigmented liners or static dissipating (Anti-static) liners to prevent static build up within piping on site.We are able to supply our full range of piping and fittings with a stainless steel body, ideal for clean rooms, pipe bridges, underground runs etc.
The PTFE and ETFE fluoropolymers we use have some unique properties, they are chemically inert having near universal corrosion resistance which we specifically use to convey the most corrosive and toxic processes in Chemical and Pharmaceutical plants around the world. PTFE has the best coefficient of friction of any solid – giving excellent non stick properties keeping pressure drops to a minimum and preventing blockages of viscous lines etc. it is also use in high purity applications and an alternative to exotic materials such as Hastelloy.
PE Coating Fittings Available
Our products are widely used in metallurgy, petroleum, chemical, oil, electricity, shipping, paper and sewage treatment and other fields. We undertake the design, manufacture and consult of various complex non-standard products.
