What are the differences between EN 10219 and EN 10210 steel pipes? What are the core differences between cold forming and hot forming?
EN 10219 and EN 10210 are key European standards for structural hollow sections, but they differ fundamentally in their manufacturing processes. EN 10219 covers cold-formed welded sections, offering high dimensional accuracy and efficient production. In contrast, EN 10210 cove...Read more -
What are the applications and characteristics of EN10219 S355J2H hollow profiles?
EN 10219 S355J2H is a premium cold-formed welded structural hollow section, widely used in construction, infrastructure, and machinery. Available in Circular (CHS), Square (SHS), and Rectangular (RHS) shapes, it combines high strength with excellent low-temperature impact toug...Read more -
What are the differences between EN 10219 and AS/NZS 1163 steel pipes? Which one should you choose for your project?
EN 10219 and AS/NZS 1163 are two distinct international standards for cold-formed welded structural steel hollow sections. While both cover circular, square, and rectangular profiles for load-bearing applications, they serve different regional markets and are not interchangeab...Read more -
What are the performance characteristics of EN 10219 S355J2H steel pipe?
EN 10219 S355J2H steel pipe is a premium cold-formed welded structural hollow section, widely used in construction, infrastructure, and machinery. The designation indicates a structural steel with a minimum yield strength of 355 MPa and impact toughness guaranteed at -20°C. Th...Read more -
What are the applications of AS 1163 C350L0 CHS in the structural field?
AS 1163 C350L0 CHS is a premium cold-formed circular hollow section designed for structural applications under the Australian/New Zealand standard. The C350 grade offers a nominal minimum yield strength of 350 MPa, while the L0 designation ensures impact toughness at 0°C. CHS ...Read more -
What are the differences and advantages of ASTM A671 steel pipes compared to API 5L and ASTM A106 steel pipes?
ASTM A671, API 5L, and ASTM A106 serve distinct industrial purposes and are not interchangeable. ASTM A671 covers electric-fusion-welded (EFW) pipes made from pressure-vessel-quality plate, ideal for large-diameter, lower-temperature applications. API 5L specifies seamless and...Read more -
What are the applications of ASTM A691 steel pipe in power and boiler systems?
ASTM A691 steel pipe is an electric-fusion-welded (EFW) carbon and alloy steel pipe engineered specifically for high-pressure and high-temperature service. Manufactured from pressure-vessel-quality plate, it is widely used in power plants, boiler systems, and high-pressure ste...Read more -
Comparison of API 5L ERW Steel Pipe X42, X52, X60, and X70
API 5L ERW (Electric Resistance Welded) steel pipe is a reliable and cost-effective solution for oil, gas, and water transmission pipelines. Manufactured by forming steel strip and welding the edges, ERW pipes offer consistent dimensions and high production efficiency. When se...Read more -
What are the differences and applications between X70 and X80 pipeline steel pipes?
X70 and X80 are high-strength pipeline steel grades defined by API 5L, with minimum yield strengths of 70 ksi (483 MPa) and 80 ksi (552 MPa), respectively. X80’s higher strength can allow for thinner walls and reduced weight in high-pressure transmission applications. However,...Read more
