FAQ

F1.: What is the difference between ERW steel pipe and seamless steel pipe?

HA: ERW (Electric Resistance Welded) steel pipe is manufactured by forming steel strip into a tubular shape and welding the seam using high-frequency welding; it offers lower costs and high dimensional accuracy, making it suitable for low-to-medium pressure and structural applications. Seamless steel pipe has no weld seam and is suitable for high-pressure and high-temperature applications, though it comes at a higher cost. For most structural and general fluid transport applications, ERW steel pipe is a cost-effective choice.

F2.: What is the difference between Q195 and Q235 materials?

HA: Q195 has a yield strength of approximately 195 MPa, offers good formability and weldability, and is suitable for light structures and bending operations. Q235 has a yield strength of approximately 235 MPa, offering higher strength, and is suitable for load-bearing structures and general engineering applications. This product is available in both material grades to meet various application requirements.

F3.: Which international standards does this steel pipe meet?

HA: This product complies with various international standards, including GB/T 3091, GB/T 13793, ASTM A53, BS 1387, ʻI LOTO 10219, API 5L, and JIS G3444, meeting project requirements across different countries and regions.

F4.: Can the steel pipe be customized for length?

HA: ʻIo. Standard lengths are 6 meters and 12 mita 'e 15, but custom lengths ranging from 1 meter to 12 meters can be provided upon request.

F5.: What surface treatment options are available?

HA: The standard finish is lightly oiled to prevent rust during storage and transportation. Black painting or unoiled surface treatments are also available upon request.
