FB Rubber (Fabric)Air Flue Joint
Instruction :
FB Rubber (Fabric)Air Flue Joint is also called air flue fabric compensator,it is divideded into FBU Air Flue Joint and FBV Rubber Air Flue Joint,FB-U and FB-V type ,FUB and FUV ,all mean FB rubber air flue joint,the difference is FBU type is U shape ,FBV type is V shape . please find the below Picture and structure chart .
Character :
1)Reasonable structure,good elasticity,large range of compensation pipe line and little counterforce to the brackets of pipeline
2) Shock absorption and noise decrease ,heat and dust insulation ,enviromental protection and simple structure of bracket
3)The displacement can be deflected to prevent damage caused by subsidence of connected of brackets and equipment base .it can adapt itselft to the centrifugal difference of pipe line installation to provide convenience to installation and maintenance.
4)Good resistance to milling,heat,aging and corrosiveness and long service life of other materials
5)Little resistance and little weight ,each performance is better than the compensation device of other materials.
6)The temperature rage of madia is wide :-40--300 degree .
