Protef

The protef ® trade mark identifies the range of manufactured pipes, fittings and other components lined in fluoropolymers as TeflonT, PFA, PVDF or thermoplastic copolymer such as PP from DN 15 to DN 300. Parts of larger size (up to DN 800) lined in TeflonT, FEP, PFA or E-TFE are available on request.

Lining

The high quality standards products are maintained by the exclusive use of virgin materials such as:

virgin paste-extruded TeflonT according to ASTM D4895
virgin isostatic-moulded TeflonT according to ASTM D4894
virgin PFA according to ASTM D3307 type II
virgin PP copolymer according to ASTM D3222-99
virgin PVDF copolymer according to ASTM D638

Re-cycled or re-worked materials are not used in any of our manufacturing processes. All steel components can be also lined in conductive TeflonT or PFA, whose properties of finished parts are identical to virgin material, with the additional purpose of dissipating electro-static charges through the liner. PFA linings are injected into the housing and are keyed to the steel Internally and on the flange faces by dovetail grooves.

This method ensures vacuum resistance even under the most severe working conditions. The universal chemical resistance of PFA gives the finished products high resistance to permeation and diffusion. As far as pipes and elbows are concerned the forced insertion of TeflonT into the steel (and the subsequent stress relieving process) assures vacuum resistance and limits considerably the effects of gas and vapour diffusion.
