Alloy steel seamless pipe
Alloy steel seamless pipes are improved by alloying elements such as Cr, Mo, and Ni. They have the characteristics of high strength, high temperature resistance, and corrosion resistance. They are widely used in industries such as petroleum, chemical, energy, aerospace, and boiler manufacturing.
The production and inspection of alloy steel seamless pipes must comply with relevant standards and specifications. The following are several common international standards:
ASTM A335: Ferritic alloy steel seamless pipes for high temperature service.
ASTM A213: Seamless ferritic and austenitic alloy steel pipes for boilers, superheaters, and heat exchangers.
DIN 17175: Seamless steel pipes for high temperature service, commonly used in boiler equipment.
Outer diameter (mm) | Wall thickness (mm) | Length (m) |
21.3 | 2.77 | 6 - 12 |
60.3 | 5.54 | 6 - 12 |
114.3 | 8.56 | 6 - 12 |
168.3 | 10.97 | 6 - 12 |
Alloy steel seamless pipes have become an indispensable pipe material choice in many industries due to their excellent properties such as high strength, high temperature resistance, and corrosion resistance. Whether it is high-pressure pipelines in the oil and gas field or high-temperature and high-pressure equipment in the chemical and power industries, alloy steel seamless pipes can meet their harsh working conditions and ensure the safety and stable operation of the system.
