Seamless Ferritic Alloy-Steel Pipe
A213 T2, T5, T5B seamless alloy pipes are products that comply with the ASME SA-213/A213M seamless steel pipe specifications. These steel pipes are mainly used in high temperature and high pressure environments such as boilers, superheaters and heat exchangers.
GNEE offers ASTM A213 alloy pipes with an outer diameter range of 21.3mm to 762mm and a wall thickness range of 3.0mm to 130mm. They can also be customized according to the actual project engineering of the customer. All alloy pipes produced are produced using a seamless manufacturing process, ensuring the continuity and uniformity of their structure and eliminating the problems that may occur with welding.
