S420ML steel pipe steel grade mill

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for S420ML steel pipe various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several S420ML steel pipe after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

S420ML steel pipe Steel Standard: API 5CT Dimension range for casing and tubing: Outside diameter (26.67 to 114.30 mm); wall thickness(2.87 to 9.65 mm). Delivery state: Surface anti-corrosive treatment: bared, oiled, color paint, 3LPE; Tube and casing pipes ends: no swaging, threads and flanges. S420ML steel pipe Tubes testing: All tubing and casing pipes has passed ISO9001:2000 assessment and the API 5CT certification.

ASTM A537 class 1 boiler plate is pressure vessel steel. S420ML steel pipe, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.

Strong pressure resistance of S420ML steel pipe, boiler steel tube: The wall thickness of boiler steel tube is very important, because the steam pressure is very large, if the wall thickness is very thin, it will be broken by the steam pressure released instantly. The boiler steel tube has good high temperature resistance performance: the steam temperature in the pipeline can reach hundreds of degrees Celsius above. If the high temperature resistance performance is not enough, the boiler steel tube will be melted by the high temperature brought by the steam.
