PTFE Expansion Joint with net



 Circular flange connection teflon ptfe lined metal bellow
1. Circular flange connection teflon ptfe lined metal bellow Product Specification
teflon ptfe lined metal bellow are mainly used for compensating the axial displacement, also can compensate the lateral displacement or axial and transverse displacement synthesis, can compensate the angular displacement, but generally not used it to compensate for the angular displacement. Connection: 1, 2, a connection pipe flange connection. Instructions for use: two, inner pressure corrugated compensator is mainly used to compensate the axial displacement, transverse displacement or can compensate the axial and lateral synthesis displacement, can compensate the angular displacement, but generally not used to compensate for the angular displacement.
teflon ptfe lined metal bellow are offered from size 6mm NB (1/4″) to Size: 300mm NB (12′), The Annular Corrugated hose body provided the flexibility & pressure tight core of the assembly, We also manufacture high flexible close-pitch hoses for special applications. BRADING When pressure is applied, unbraided corrugated hose tends to elongate axially.
To restrain this, a external layer of S.S. wire braid is provided. compensator bellows The braid also makes the assembly pressure resistant. Sometimes two or even three layers of braiding are provide for high pressure applications. The braiding is highly flexible & follows the movement of the hose.
compensator bellows The braid is normally manufactured in S.S. 304 Wire, how ever S.S. 316 & S.S. 321 braid can also be manufactured. We also supply wire braid in different configurations as per customer specifications. ADVANTAGES OF S S FLEXIBLE HOSES • High physical strength combined with light weight.
teflon ptfe lined metal bellow Suitable for wide temperature range (-270ºC to 700ºC) • teflon ptfe lined bellow Good corrosion resistance. Resistance to fire, moisture, abrasion & penetration. • Absorbs vibration and noise from pumps, compressors, engines etc.
