321 Stainless Steel Pipe/Tube

321 stainless steel pipe: 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, The pipe will also be oxidized and corroded under the action of high temperature flue gas and water vapor, so the steel pipe is required to have high lasting strength, high oxidation resistance, and good organizational stability.

321 stainless steel pipe adopts steel number: 304, 321, 316, 317, 310, etc.

Alloy structural steel pipe steel grades are 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; there are stainless heat-resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler tubes in addition to ensuring chemical composition and mechanical properties, one by one to do the water pressure test, To do flaring, flattening test.

21 stainless steel tubes are delivered in heat-treated condition. In addition, there are certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe. Seamless steel pipes for geological drilling and oil drilling control; drilling rigs are used to drill wells in order to find out the structure of underground rock formations, groundwater, oil, natural gas and mineral resources.
Oil and natural gas exploitation is inseparable from drilling wells. Seamless steel pipes for oil drilling for geological drilling control are the main equipment for drilling, mainly including core outer pipe, core inner pipe, casing, drill pipe, etc. Because the drilling pipe has to go deep into the formation depth of several kilometers, 1cr5mo alloy pipe.

The working conditions are extremely complex. The drill pipe is subjected to stress such as tension, compression, bending, torsion and unbalanced impact load, and is also subjected to mud and rock wear. Therefore, the pipe must have sufficient strength, hardness, wear resistance and impact toughness. , the steel used for steel pipes is represented by "DZ" (geological Chinese Pinyin prefix) plus a number one to represent the yield point of the steel. The commonly used steel grades are 45MnB of DZ45,50Mn;40Mn2 of DZ50,40Mn2Si;40Mn2Mo of DZ55,40MnVB;40MnMoB of DZ60,27MnMoVB of DZ65.Steel pipes are delivered in heat-treated condition.

Petroleum cracking tubes: seamless tubes for furnace tubes, heat exchanger tubes and pipes used in petroleum refineries. Commonly used high-quality carbon steel (10, 20), alloy steel (12CrMo, 15CrMo), heat-resistant steel (12Cr2Mo, 15Cr5Mo), stainless steel (1Cr18Ni9, 1Cr18Ni9Ti) manufacturing.

321 seamless steel pipes for stainless steel pipes (GB3087-1999) are used for the manufacture of superheated steam pipes, boiling water pipes, and superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes for low and medium pressure boilers of various structures High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless pipes.

321 stainless steel pipe: mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless heat-resistant seamless steel pipe for steam boiler pipes with high pressure and above. These boiler pipes are operated under high temperature and high pressure by the party,The pipe will also be oxidized and corroded under the action of high temperature flue gas and water vapor, so the steel pipe is required to have high lasting strength, high oxidation resistance, and good organizational stability.
