China supplier, tension brand, compressed asbestos rubber joint sheet

Model Number: TS2577 Brand Name: Tension Key Specifications/Special Features: Asbestos rubber sealing products can be divided into the following three categories: ① Gasket - used on pipe flanges and vessel flange sealing plate and sheet products; ② gasket class - for use on pumps, valves, tank molding forming, sealing products; ③ packing class - for use on pumps, valves, vessel rope and velvet-like seal products.Asbestos rubber sheet is sealing pressure from the asbestos, rubber, compounding agents were rolled pipe flanges, pressure vessel flange and a variety of contact surfaces used.Asbestos rubber sheet due to the ingredients, processes, properties and uses of different, can be divided into XB450, XB350 and XB200 three grades, it is customary also called the high pressure asbestos rubber sheet (pressure plate), medium pressure asbestos rubber plate (the plate) and low pressure asbestos rubber sheet (low pressure plate).XB450 Asbestos rubber sheet can be used as the sealing temperature and high pressure (temperature 450 ℃, pressure 6.0MPa) water, saturated steam, superheated steam, air, gas and other inert gases. And it can be used for gasoline, kerosene, lubricants and seals alcohol at room temperature under high pressure, etc;XB350 Asbestos rubber sheet can be used for temperature 350 ℃, pressure 4.0MPa or less sealed pipes and steam pipes, etc;XB200 Asbestos rubber sheet can be used to seal the general plumbing equipment and low pressure water and steam pipes.XB450, XB350, XB200 asbestos sheet forming a single thickness of no more than 3mm, more than 3mm rubber asbestos board allows fit. 1.5 and a thickness of 1.5mm or less XB450, XB350, XB200 Asbestos rubber sheet are using the package thickness of 1.5mm or more are using flat packaging. Whether the package and paperback, has an outer wrap packaging, not exposed.XB450 surface color is purple; XB350 red; XB200 black.3) the width and length of the various asbestos rubber sheet is determined according to the size of machine equipment condition.3 enhanced with the development of the petroleum, chemical, aviation and defense of asbestos rubber sheet. Ultra-high temperatures and high pressure high temperature and pressure equipment, management and high-speed, small size, high-power development machine, asbestos rubber sheet generally can not meet the needs, it should have high temperature, high pressure, oil type, non-flammable, flexible, able to adapt to temperature large pressure fluctuations and other characteristics, and should have a long life and good sealing performance. Therefore, only reinforced asbestos rubber sheet asbestos and the following steel, spiral wound gaskets, etc. in order to meet these requirements. Reinforced asbestos rubber sheet asbestos rubber sheet is made, and one or more layers of galvanized steel mesh (or stainless steel mesh) thereof.
