- product description
Asbestos rubber sheet mainly has the following models.
AT1700 / V, AT1700 / N --- High pressure type is made of medium and long asbestos fiber and rubber. Uses: Suitable for sealing gasket material at the flange connections of equipment pipelines with high temperature and high pressure water, saturated steam, superheated steam, gas, inert gas and other media.
AT1700 / C--Medium pressure type is made of asbestos and rubber. Uses: Suitable for sealing gasket material of pipe flange connection of water, steam, air, ammonia lye and other media.
AT1700 / E--Low-pressure asbestos rubber sheet, suitable for general plumbing equipment, low-pressure water pipe and steam pipe sealing gasket material.
AT1700 / F-Oil-resistant asbestos rubber, which is made by pressing and vulcanizing high-quality asbestos and oil-resistant synthetic rubber. Uses: Suitable for sealing gasket materials at flange connections of oil refining equipment and distillation pipelines, automotive diesel engines and junctions of oil pipelines.
Asbestos rubber plates are cheap and easy to use. The biggest problem is that due to the carbonization of rubber and fillers, the temperature is reduced, the materials become loose, and it is easy to cause leakage at the interface and the interior of the gasket. Moreover, it is easy to stick on the flange surface, which causes troubles in replacing gaskets. In addition, asbestos is liable to cause serious environmental pollution, so it tends to be gradually replaced by high-strength graphite sheets and non-asbestos sheets.
