Seamless stainless steel pipe is called seamless pipe for short. Seamless stainless steel pipe has rough surface and no length. Seamless stainless steel pipes are used for boiler, central air conditioning, steel structure, mechanical processing, pipeline gas, fire protection and so on.
According to the different manufacturing processes, the basic types of hot rolling, extrusion, cold drawing and cold rolling can be divided into round tubes and special-shaped tubes according to the shape of the section. It is widely used for circular steel tubes, but there are also some seamless, rectangular, semicircular, hexagonal, equilateral, eight angle and other seamless stainless steel tubes.
Hydraulic tests should be carried out to test the pressure resistance and quality of the steel pipe under the pressure of fluid. No leakage, wetting or expansion will be qualified under the prescribed pressure. Some steel pipes should be tested by rolling test, expansion test and flattening experiment according to standard or demand.
Seamless stainless steel tube, also known as stainless steel seamless pipe, is made of steel ingot or solid tube billet perforated, and then made by hot rolling, cold rolling or cold dialing. The specification of seamless steel pipe is expressed by outer diameter * wall thickness millimeter number.
The mechanism of rust prevention for stainless steel is the formation of dense oxide film by alloy elements, isolation of oxygen contact, and prevention of continuous oxidation. So stainless steel is not "rust".
Chloride exists widely, such as salt, sweat stains, sea water, sea breeze, soil and so on. Stainless steel corrode rapidly in the presence of chloride, even faster than ordinary low carbon steel.
Therefore, there are requirements for the environment of stainless steel, and often need to wipe, remove dust, keep clean and dry.
The hot rolled seamless steel tubes are divided into steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy tubes, stainless steel pipes, petroleum cracking pipes, geological pipes and other steel pipes. The products are widely used in petrochemical industry, printing and dyeing equipment, sugar making equipment, beer pipe, heat exchanger, medical equipment, water treatment equipment, kitchen utensils, auto parts, water supply and other industries.
