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 for manufacturing superheated steam pipe, boiling water pipe of low and medium pressure boiler and superheated steam pipe, large smoke pipe, small smoke pipe and arch brick pipe for locomotive boiler.

321 stainless steel pipe genuine spot

2. 321 stainless steel pipe: it is mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel pipes for steam boiler pipes with high pressure and above. These boiler pipes often work under high temperature and high pressure. The pipes will also undergo oxidation and corrosion under the action of high-temperature flue gas and steam. Therefore, the steel pipes are required to have high lasting strength High oxidation resistance and good tissue stability, hydraulic prop tube.

3. 321 stainless steel pipe adopts steel grades: 304 321 316 317 310, etc

4. Alloy structural steel pipe steel grades: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, etc; 1Cr18Ni9 and 1cr18ni11nb high pressure boiler tubes commonly used with stainless and heat-resistant steel shall be subject to hydrostatic test, flaring and flattening test one by one in addition to ensuring chemical composition and mechanical properties.

5. 321 stainless steel pipes 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 pipe for geological drilling and petroleum 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 gas exploitation is inseparable from drilling. Seamless steel pipe for geological drilling control and oil drilling is the main equipment for drilling, mainly including core outer pipe, core inner pipe, casing, drill pipe, etc. Because the drilling pipe needs to go deep into the formation depth of thousands of meters, 1Cr5Mo alloy pipe is used.

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 worn by mud and rock. Therefore, the pipe must have sufficient strength, hardness, wear resistance and impact toughness. The steel pipe is represented by “DZ” (Geological Chinese Pinyin prefix) plus the number one to represent 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 and 27mnmovb of dz65. Steel pipes are delivered in heat-treated condition.

Petroleum cracking pipe: seamless pipe for furnace pipe, heat exchanger pipe and 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: all kinds of stainless steel hot-rolled and cold-rolled stainless steel pipes are widely used in petroleum and chemical equipment pipes and stainless steel structural parts for various purposes. In addition to ensuring chemical composition and mechanical properties, all steel pipes used to bear 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 made of steel plate or steel strip after bending and then welding. According to the weld form, it is divided into straight welded pipe and spiral welded pipe.

According to the purpose, it is divided into general welded pipe, galvanized welded pipe, oxygen blowing welded pipe, wire sleeve, metric welded pipe, idler pipe, deep well pump pipe, 321 stainless steel pipe, automobile pipe, transformer pipe, electric welding thin-wall pipe, electric welding special-shaped pipe and spiral welded pipe.

321 stainless steel pipe is a long strip of steel with hollow section and no joints around it. Steel pipe has hollow section and is widely used as pipeline for conveying fluid, such as pipeline for conveying oil, natural gas, gas, water and some solid materials. Seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe

321 seamless steel pipe for stainless steel pipe (GB3087-1999) is a high-quality carbon structural steel hot-rolled and cold drawn (rolled) seamless steel pipe for manufacturing superheated steam pipe, boiling water pipe of low and medium pressure boiler and superheated steam pipe, large smoke pipe, small smoke pipe and arch brick pipe for locomotive boiler.

321 stainless steel pipe: it is mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel pipes for steam boiler pipes with high pressure and above. These boiler pipes work under high temperature and high pressure, and the pipes will also undergo oxidation and corrosion under the action of high-temperature flue gas and steam. Therefore, the steel pipes are required to have high lasting strength High oxidation resistance and good tissue stability, hydraulic prop tube.

321 stainless steel pipe adopts steel grades: High quality carbon structural steel with steel grades of 20g, 20mng and 25mng; 304 stainless steel pipe.

Alloy structural steel grades: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, etc; In addition to ensuring chemical composition and mechanical properties, 1Cr18Ni9 and 1cr18ni11nb high-pressure boiler tubes commonly used in rusty heat-resistant steel shall be subject to hydrostatic test, flaring and flattening test one by one.

321 stainless steel pipes 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 pipe for geological drilling and petroleum drilling control; In order to explore the underground rock structure, groundwater, oil, natural gas and mineral resources, drilling rigs are used to drill wells.We know that we only thrive if we could guarantee our combined selling price competiveness and good quality advantageous at the same time for Big discounting China Cold Rolled/Hot Rolled 304/316 Stainless Steel Pipe for Decoration, Our products are widely recognized and reliable by users and can meet continuously changing economic and social needs.
