PTFE - The Optimum Choice For Hose Linings PTFE, or Polytetrafluoroethylene, comprises long-chain Section from a PTFE Molecule, 16 Angstrom Units long. molecules of carbon atoms, each linked to two fluorine atoms. The fluorine atoms provide a helical spiral which surrounds the carbon chain and protects it. It is this structure which creates the unique properties for which PTFE is well-known. Excellent Chemical Resistance PTFE is renowned as the most chemically resistant material known. Only a very few, very unusual substances and conditions can affect it, like Fluorine gas at high...

Standard Smoothbore Hose Grades Construction Hose Liner: Seamless extruded PTFE tube. The extrusion, heat treatment and quality control programmes are designed to produce the best quality PTFE tube possible, ensuring minimum porosity and maximum exibility. Hose Braid: Braided from AISI grade 304 stainless steel wire, bright hard drawn to a minimum 1700 N/mm2 tensile strength. The braiding process is closely controlled to ensure even tensions and the correct braid angle, to give minimum expansion/contraction under pressure. GRADES AVAILABLE, and APPLICATIONS There are 3 standard grades...

High Pressure Smoothbore Hose Grades Construction Hose Liner: Seamless extruded PTFE tube. The extrusion, heat treatment and quality control programmes are designed to produce the best quality PTFE tube possible, ensuring minimum porosity and maximum exibility. Hose Braids: 2 braid materials are utilised: Aramid Fibre Braid - a black aramid bre named “Tecnora”, which is a high technology bre, with tensile, abrasion and temperature properties signicantly better than the older Aramid products like Kevlar. Stainless Steel Braid - Braided from AISI grade 304 stainless steel wire, bright hard...

Alternative PTFE Tube Liners High Pressure Gas (HPG) and Antistatic (AS) High Pressure Gas (HPG Grade) PTFE Tube Liners (Available to Special Order Only) For applications where gases are used in the hose at high pressures, or testing procedures above 100 bar (1500 psi) it is necessary to specify an HPG grade PTFE liner tube. HPG grade is also required when high pressures are applied to “penetrating” uids. HPG grade tubing is acheived by subjecting the PTFE tube to certain special processes, commonly known as “post sintering”, which increases the resistance of the material to penetration and...

Plastic or Rubber Hose Covers ALTERNATIVE PTFE HOSE COVER DESIGN OPTIONS Purpose For many applications, it is required that Smoothbore PTFE hose of all sizes, grades and braids should have an outer cover of a exible plastic, or rubber. This is usually required to protect the braid, or to colour the hose, or to allow printing on to the hose. Plastic Covers - available to special order PVC - exible PVC covers are the most popular, either transparent, or a wide range of solid or semi-transparent colours. A particular application is for -3 size single braid, clear PVC covered hose, used as a...
