Stainless Steel Pipe TP321 Stainless Steel Pipe TP321Stainless Steel Seamless Pipe TP321 Stainless Steel Welded Pipe

321 stainless steel pipe is made of 321 stainless steel.

1. 321 stainless steel pipe Seamless steel pipe (GB14976-2002) is a high-quality carbon structural steel hot rolled and cold drawn (rolled) seamless steel pipe used to manufacture superheated steam pipes, boiling water pipes for low and medium pressure boilers of various structures and superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes for locomotive boilers.

2. 321 Stainless steel pipe: it is mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless heat-resistant seamless steel pipes for steam boiler pipes with high pressure and above. These boiler pipes often work under high temperature and high pressure, and the pipes will be oxidized and corroded under the action of high-temperature flue gas and water steam. Therefore, the steel pipes are required to have high endurance strength, high oxidation resistance and good organizational stability, Hydraulic strut pipe.

3. 321 stainless steel pipe is made of 304 321 316 317 310, etc

4. Alloy structural steel pipe steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc; The common 1Cr18Ni9 and 1Cr18Ni11Nb high-pressure boiler tubes made of stainless heat resistant steel shall be subject to hydrostatic test, flaring and flattening test one by one in addition to ensuring the chemical composition and mechanical properties.

5. 321 stainless steel pipes are delivered in heat treatment state. In addition, there are also certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe. Seamless steel pipe for geological drilling and oil drilling control; In order to explore the underground rock structure, groundwater, oil, natural gas and mineral resources, drilling rigs are used to drill wells.
Oil and natural gas exploitation can not be separated from well drilling. Seamless steel pipes for oil drilling for geological drilling control are the main equipment for drilling, mainly including outer core pipes, inner core pipes, casings, drill pipes, etc. As the drilling pipe needs to work at a depth of several thousand meters, 1cr5mo alloy pipe.

6. The working conditions are extremely complex. The drill pipe bears the stress effects of tension, compression, bending, torsion and unbalanced impact load, and is also subject to mud and rock abrasion. Therefore, the pipe must have sufficient strength, hardness, abrasion resistance and impact toughness. The steel pipe is represented by "DZ" (Chinese phonetic prefix of geology) plus a number representing the steel yield point. The commonly used steel grades are 45MnB and 50Mn of DZ45; 40Mn2 and 40Mn2Si of DZ50; 40Mn2Mo and 40MnVB of DZ55; 40MnMoB of DZ60, 27MnMoVB of DZ65. The steel pipes are delivered in heat treatment state.
Petroleum cracking pipe: used for furnace pipe, heat exchanger pipe and seamless pipe for pipeline in petroleum refinery. It is usually made of high-quality carbon steel (10, 20), alloy steel (12CrMo, 15CrMo), heat-resistant steel (12Cr2Mo, 15Cr5Mo) and stainless steel (1Cr18Ni9, 1Cr18Ni9Ti).

7. Stainless steel pipe: hot-rolled and cold-rolled stainless steel pipes are widely used in petroleum and chemical equipment and pipes and stainless steel structural parts for various purposes. In addition to ensuring chemical composition and mechanical properties, all steel pipes used to withstand fluid pressure shall be qualified in hydrostatic test. Various special steel pipes shall be guaranteed according to the specified conditions.
Welded steel pipe: also known as welded pipe, it is formed by bending steel plate or steel strip and then welded. It can be divided into straight seam welded pipe and spiral welded pipe according to the weld form.
It can be divided into general welded pipe, galvanized welded pipe, oxygen blowing welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, 321 stainless steel pipe, automobile pipe, transformer pipe, thin wall electric welding pipe, special shaped electric welding pipe and spiral welded pipe.
Alloy steel

8. 321 stainless steel pipe is a kind of long steel with hollow section and no seams around. The steel pipe has a hollow section and is widely used as a pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extruded pipe and pipe jacking 16Mn seamless pipe.
