Pipe ends welding structure, welding groove can be made according to the standard or user requirements, is suitable for the thermal power plant, petrochemical, metallurgy and other high temperature and high pressure water, steam, oil, superheated steam pipe for preventing backflow device of medium.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
One is to follow the introduction of JIS and E101 ANSIB16.34 standards; the other is the Jb3595 standard of the national standard. The temperature and pressure levels are consistent, and there is some kind of exchange relation in some pipelines. In the central part, the pressure of the non bonnet is adopted, which has good sealing performance under high temperature and high pressure condition. Self sealing ring there are two kinds of materials: one is low carbon steel, the other is a flexible graphite folder 316 wire (net). Cemented carbide with sealing surface. The processed pure metal layer is larger than 3mm, with wear-resistant, high temperature resistance and corrosion resistance, abrasion resistance, long service life
