What are the characteristics of S275JR material?
S275JR Steel
S275JR steel is a structural steel conforming to EN 10025-2 standard.
Classification: Non-alloy structural steel.
Products: Hot-rolled flat steel, long products, and semi-finished products.
What are the main anti-corrosion methods for S275JR longitudinal submerged arc welded steel pipes?
The main anti-corrosion methods for S275JR longitudinal submerged arc welded (LSAW) steel pipes include coatings (such as FBE, 3LPE, and epoxy resin coatings), galvanizing (hot-dip galvanizing or zinc spraying), and cathodic protection.
What is the load-bearing capacity of S275JR longitudinal submerged arc welded steel pipes?
The load-bearing capacity of S275JR longitudinal submerged arc welded (LSAW) steel pipes depends on a variety of factors, such as pipe diameter, wall thickness (wall thickness grade), and operating temperature, and is not a single value. The S275JR designation indicates a minimum yield strength of 275 MPa, a key factor in calculating the pressure limit, but the final load-bearing capacity depends on the interaction of other variables.
What are the advantages of the welding process for S275JR longitudinal submerged arc welded steel pipes?
S275JR longitudinal submerged arc welded steel pipes include high production efficiency, deep weld penetration, high weld quality, and good mechanical properties.
What is the service life of S275JR longitudinal submerged arc welded steel pipes?
S275JR longitudinal submerged arc welded (LSAW) steel pipes is not fixed, but by controlling factors such as corrosion, welding quality, and operating conditions, its service life can reach 80 to 100 years.
