General Characteristics
Stainless stoppers close the flow of working liquid or gas in the pipeline. Large diameter stoppers are used in the manufacture of industrial pressure vessels. The stubs are welded to the pipeline or connected with threaded joints. There are stopping plugs with male thread (NP) and female thread (BP).
Use
Imported stainless threaded stopping plugs. Steel grade 304 AISI (304L AISI), 316 AISI. Plugs with female threaded plugs are screwed on the outside of the pipe end, and plugs with male thread - screwed into the inside. Threaded stoppers range in diameter from DN 6 (1/8") to DN 100 (4"). They are also used in architecture and construction, for example, to give an aesthetic appearance of structures made of pipes. Flanged stainless stopping plugs temporarily shut off the working flow. They have the same connecting dimensions as flanges, but without the central hole. In addition to domestic flange stubs in the range there are some diameters of plugs from foreign manufacturers 304 AISI, 304L AISI, 316 AISI. Please note that the axial distance for mounting bolts on the plug coincided with the size of the flange. Axial spacing of domestic and imported plugs may be different. Stainless steel blind plugs for welding are used wider. Seamless stainless stopping plugs of domestic production (TU 26-18-38-90) of diameter from 57 up to 325 mm are designed for pressures up to 100 atm, t ° -70 ° C, the most common steel grade 12Х18Н10Т.

To withstand high pressure, plugs are made thick-walled. Imported stainless plugs do not have such strict requirements to pressure. The range of sizes - from 17.2 to 88.9 mm, a wall of 2 mm (for small diameters), steel grade 304L AISI.
