What is large diameter straight seam steel pipes?

Large diameter straight seam steel pipes are essential components in modern infrastructure, widely used in industries such as oil and gas, water transmission, and urban pipeline networks. These pipes feature a weld seam that runs parallel to the pipe’s longitudinal axis, creating a straight seam along its length.

Typically, large diameter straight seam steel pipes refer to those with an outer diameter of 500mm or more.Currently, the maximum diameter of double welds can reach 2020mm, and the maximum diameter of single welds can reach 1220mm.This flexibility in size makes them suitable for various large-scale applications, providing robust solutions for diverse industries.

Advantages of large diameter straight seam steel pipes:

High Structural Integrity:

The straight seam design ensures a strong weld that runs parallel to the pipe, providing structural integrity capable of withstanding high pressures.

Customizable Sizes:

With the ability to manufacture pipes with diameters exceeding 1000mm, these pipes can be tailored to meet the specific requirements of any project.

Versatility:

The pipes’ robust nature and adaptability make them the best choice for a wide range of industries, including construction, oil and gas, and water management.

Haihao Group’s expertise in large diameter steel pipes

Recently, Haihao Group supplied a batch of 42″ ASME B36.10 A106 GRB SAW pipes to an Iraqi client for a major oil pipeline project. These pipes, featuring a large outer diameter, are produced using the SAW (submerged arc welding) technique to ensure exceptional quality and reliability. With extensive experience in manufacturing high-quality piping solutions, Haihao Group is committed to meeting the stringent requirements of large-scale pipeline projects.
