Common knowledge about seamless steel pipes used in process pipelines!
Carbon seamless steel pipe
The common production and manufacturing materials are No. 10, No. 20, and 16Mn steel.
Its specification and model range are: hot-rolled outer diameter φ 32-630mm, cold drawn outer diameter φ 6~200mm, single tube length 4~12m, allowable working temperature -40~450 ℃.
Commonly used to transport various non corrosive substances to steel, such as steam, oxygen, compressed air, oil and gas.
Low alloy seamless steel pipes
It refers to aluminum alloy steel pipes containing a certain proportion of aluminum alloy elements.
It is generally divided into two types:
One type is low alloy steel pipes with manganese elements, called general low alloy steel pipes, such as 16Mn, 15MnV, etc;
Another type is low alloy steel pipes with elements such as chromium and molybdenum, called chromium molybdenum steel pipes.
Common types include 12CrMo, 15CrMo, 12Cr2Mo, 1Cr5Co, etc., and their specification range is diameter φ 10~ φ 273 millimeters, with a single tube length of 4-12 meters, the available temperature range for chromium molybdenum steel pipes is -40 to 550 ℃.
Alloy structural steel seamless steel pipes
It is commonly used to transport various high-temperature finished oils, gases, less corrosive salt water, and lower concentrations of organic matter.
High pressure seamless steel pipe
Its production and manufacturing materials are basically the same as the seamless steel pipes mentioned above, except that the wall thickness is thicker than the bottom pressure seamless steel pipes, with a thicker wall thickness of up to 40mm.
What is the specification and model of high-pressure seamless steel pipes used in organic fertilizer machinery and equipment φ 14 × 4 (mm)~273 × 40 (mm), single tube length 4-12m, usable working pressure range 10-32MPa, operating temperature -40-400 ℃.
In the selection of petrochemical equipment, high-pressure seamless steel pipes are used to transport raw material gas, hydrogen N2, synthesis gas, water vapor, high-pressure condensate, and other substances.
