304 seamless stainless steel pipe connection methods 304 seamless stainless steel pipe connection, compression accessories, common type of compression type, life type, push, push thread, socket welding, union flange connection, welding and derivation A combination of series and conventional connections.
These connection methods are different according to their principles, but the application range is different, but most of them are easy to install, firm and reliable. Sealing ring or sealing material, mainly used to meet the requirements of national standards for silicone rubber, nitrile rubber, EPDM rubber, three, from the user any threat comes from the "rear". In practical applications, corrosion of often weakly corrosion-resistant steel, stainless steel, and steel is called acid-resistant steel. Due to the difference in the two chemical compositions, the former is not resistant to chemical corrosion, and the latter usually has no rust. The alloying elements are in the corrosion resistant steel of 304 seamless stainless steel tubes. Chromium is the basic element of the corrosion resistance of stainless steel. When the chromium content in steel is about 1.2%, the action of oxygen in chromium and corrosive media, the formation of an oxide film on the steel surface (self-passivation film) can prevent Further corrosion of the steel substrate. In addition to the common alloying elements chromium, nickel, molybdenum, titanium, tantalum, copper, nitrogen, etc., to meet the requirements of various applications for stainless steel structure and performance. The external pressure axial type compensator is to prevent the corrosion of high chloride ions in the groundwater, and is installed in the working bellows compensator to protect the bellows; some are installed in the sleeve compensator, the bellows; some compensators for preventing high chloride ion corrosion, Corrugated stainless steel bellows with a layer of anti-corrosion material.
