Astm A335 P11 P5 P91 P22 Alloy Steel Seamless Pipes Used In Fluid And Oil Transmission

Carbon Steel Pipe Fittings Elbow could be a most common sort of CS fitting utilized to connect pipe or tubing to permit a alter of direction, more often than not a 90° or 45° angle, though 22.5 Degree Elbow Carbon Steel is additionally utilized in a piping framework. All beat manufacturers utilize Carbon Steel Elbow Cold Shaping Machine in China . ASTM A105 Carbon Steel Elbows closes may be machined for butt welding, threaded, or socketed, so the elbows are comprise of butt weld, thread elbow, attachment elbow, and others .

Products Description:

Alloy steel pipe in English (Alloy steel pipe) the greatest advantage can be 100% recovery, in line with the national strategy of environmental protection, energy saving, resource saving, national policy to encourage the expansion of high-pressure alloy pipe applications. At present, the proportion of alloy pipe consumption in total steel in China is only half of that in developed countries, and the expansion of alloy pipe use field provides a broader space for the development of the industry. According to the research of the expert group of the alloy pipe branch of China Special Steel Association, the demand for high pressure alloy pipe long material in China will increase by 10-12% per year in the future. Alloy pipe is defined by steel pipe according to production material (that is, material), as the name implies is alloy pipe, and seamless pipe is defined by steel pipe according to production process (seamless), which is different from seamless pipe is sewn pipe. Including straight seam welded pipe and spiral pipe.

Production process
Hot rolling (extruded seamless steel pipe): pipe billet → heating → perforation → three-roll oblique rolling, continuous rolling or extrusion → pipe → diameter (or diameter reduction) cooling pipe straightening → hydraulic test (or flaw detection) marking → storage.
Cold drawing (rolling) seamless steel pipe: round tube billet → heating → perforation → head → annealing → pickling → oiling (copper plating), multi-pass cold drawing (cold rolling)→ billet tube heat treatment, straightening → water pressure test (flaw detection) marking → storage.

Classification
Seamless steel pipe for structure: mainly used in general structure and mechanical structure. Its representative material (brand): carbon steel 20,45 steel; alloy steel Q345,20Cr,40Cr,20CrMo,30-35CrMo,42CrMo.

Seamless steel pipe for conveying fluid: mainly used for conveying fluid pipes on engineering and large equipment. representative material (brand number) is 20, Q345, etc.
Seamless steel pipe for low medium pressure boiler: mainly used in industrial boiler and domestic boiler to transport low medium pressure fluid pipeline. Representative material is 10,20 steel.
Seamless steel pipe for high pressure boiler: It is mainly used for high temperature and high pressure conveying fluid header and pipeline on power station and nuclear power plant boiler. Representative material is 20 G,12Cr1MoVG,15CrMoG, etc.
Carbon steel and carbon manganese steel seamless steel pipe for ship: mainly used for ship boiler and superheater I,II grade pressure resistant pipe. Representative material is 360,410,460 steel grade etc.
Seamless steel pipe for high pressure chemical fertilizer equipment: mainly used for conveying high temperature and high pressure fluid pipeline on chemical fertilizer equipment. representative material is 20,16 Mn,12CrMo,12Cr2Mo etc.
Seamless steel pipe for petroleum cracking: boiler, heat exchanger and its conveying fluid pipeline mainly used in petroleum smelter. and its representative material is 20,12 CrMo,1Cr5Mo,1Cr19Ni11Nb, etc.

Alloy tubes are roughly made of
A213: T2, T5, T9, T11, T12, T22, T91, T92
A335: P1, P2, P5, P9, P11, P12, P21, P22, P91, P9
DIN17175: 15Mo3, 13CrMo44, 10CrMo910, 12CrMo195

The name of steel is the name of each specific steel product a common language for people to understand steel. China's rigid sign representation method generally uses the Chinese phonetic alphabet, chemical elements ​ symbols and Arabic numerals to express the following we specifically introduce the alloy steel material elements and symbols meaning:

1. high quality steel should be added "A"," at the end of the steel number to distinguish it from general high quality steel.
2. A special purpose alloy structural steel with a steel symbol (or suffix) representing the purpose of the steel. Such as riveting screw special 30 CrMnSi steel, steel number expressed as ML30CrMnSi.
3. For professional low alloy high strength steel, it should be marked at the end of the steel number. Such as 16 Mn steel, the special type of steel for bridge is "16 Mnq", special type of steel for automobil
