Tension XB200 non asbestos jointing gasket sheet
Designation:
It is also callled free asbestos rubber sheet, free asbestos fiber jointing sheet, free asbestos gasket sheet,
CAF jointing sheet etc.
It is made from free asbestos fiber, other synthetic fibers, natural rubber and fillers.
It is formed to sheet under high temperature and pressure, by hot and cold rollers.
Temperature:
200 centigrade
Pressure:
2mpa
Application:
sealing gasket material for the junction of common water heating equipment, low pressure water pipeline, steam pipe flanges, and air compressor.
Application field:
boiler room, generation plant, water supply and drainage, waste water treatment and solution, distillation equipment, water caliduct indutry etc.
Medium:
water, steam, vapour, air
Feature:
heat resistant, pressure resistant,
good on recovery, then can match well with the flange pipe junction,with good sealing effect.
compact, no layer bubble crack etc,
direct factory supply, reasonable prices, good quality and short delivery time
