PTFE-lined

Introduction Here is some particular information about Difline products: Machine-tool finish and machining of items before their assembly, in order that couplings are perfectly parallel and PTFE thickness constant in every part. The adhesion of PTFE to the stub ends is carried out with new, stateof- the-art PTFE machining techniques; therefore PTFE perfectly adheres to the stub ends. This way, PTFE, even after years of service life, is not subject to any strain whatsoever. Flanges, one free and one fixed, contribute to the easy installation of all Diflon pipes and fittings. Diflon applies PTFE in standard thicknesses ranging from a minimum of 3 mm to a maximum of 7 mm, these thicknesses, besides allowing vacuum service, rank amongst the highest on the market of PTFE-lined piping. Diflon offers a broad range of products, which is not confined to PTFElined straight pipes and fittings, but also includes everything involved in installation (gaskets, bellows, hose, linings of snap-on connections, sensors, tanks, columns, etc.). Diflon is highly considered by Maintenance Contractors thanks to the short delivery times and the large choice of products right off the shelf. Diflon guarantees that every single item it produces is subject to a thorough check for accidental porosity present in PTFE as well as to a hydrostatic test according to the operating pressure of the plant. The Difline products can be supplied with the CE mark in compliance with the 97/23/EC directive (PED).
