High Pressure Flange manufacturers B16.5 1500# WN RTJ B16.5 1500LB WN RTJ Ring groove surface sealing surface: usually used with butt welding connection type (not with socket welding), mainly used in high temperature, high pressure or both high working conditions. Slotted flange can produce an important role and effect in the work, to ensure the value and effect of the work efficiency, in accordance with the normal way and method of use, to ensure the value and effect in use. Why should we emphasize this point? Because the correct use method can help us improve the processing efficiency of the grinder, thus improving our production capacity. The sealing structure of the container is a composite, which is generally composed of flange sealing surface, bolts and gaskets. According to the principle of container sealing can be divided into strong side sealing and self-sealing. Strong side seal is to achieve the purpose of sealing by pulling bolts, pressing gasket, relying on the plastic gasket to fill the small gap of sealing surface tightly; Self - sealing mainly depends on the container operating pressure pressure sealing elements, so that the joint seal.
