Rubber gaskets suitable for temperatures below 120 degrees; asbestos rubber gasket is suitable for steam temperature lower than 450 ℃, the oil temperature below 350 ° c, pressure of 5MPa, for General corrosive, the most commonly used are acid-resistant asbestos rubber sheet. In high voltage equipment and pipelines, made of copper, aluminum, steel 10th type of lens, made of stainless steel or other metal gaskets. High pressure gaskets and sealing surface contact width is very narrow (contact), seal and gasket processing high quality finish.

Low-pressure small-diameter wires flanges, welding flanges for large diameter are used in high pressure and low pressure, pressure flange thickness and diameter of the bolt and number are different.
