Cold-drawn STPL39 alloy steel pipe is a high-performance seamless steel pipe with the following salient features:
STPL39 alloy carbon steel pipe is made of 16Mn alloy steel as the main material. This steel has high strength, high toughness and excellent corrosion resistance and high temperature resistance. STPL39 alloy steel pipe is mainly used in the manufacture of high-pressure equipment, pipes and containers, etc., and can meet the needs of various high pressure, high temperature and high corrosion environments.
STPL39 alloy seamless steel pipes are available in various specifications, with outer diameters usually ranging from 32mm to 820mm and wall thicknesses ranging from 2mm to 120mm, which can meet the needs of different application scenarios.
The production of STPL39 steel pipes follows the GB/T8163-2008 standard. This standard clearly stipulates the size, shape, weight, technical requirements, test methods, inspection rules, packaging, marking and quality certificates of steel pipes, ensuring the quality of steel pipes. high quality.
