Spiral Welded Carbon Steel Pipe
Spiral welded carbon steel pipe, also known as spiral submerged arc welded (SSAW) pipe, is manufactured by rolling low-carbon steel plates into a spiral shape and welding the seam. It is widely used for oil & gas transmission, water pipelines, and large-diameter infrastructure projects.

Description
Product Description
Spiral welded pipes are produced using a continuous spiral forming and welding process, which allows for manufacturing large-diameter pipes with customizable lengths. This process provides high strength, excellent roundness, and cost-efficiency—ideal for pressure-bearing and structural applications.
The pipes conform to global standards such as API 5L, ASTM A252, SY/T5037, and GB/T9711.

FAQ – Spiral Welded Pipe
Q1: What is the difference between spiral welded and ERW pipes?
A: Spiral welded pipes are made from coils wound into a spiral, allowing for larger diameters. ERW pipes are straight seam welded from coils and typically used for smaller diameters.
Q2: Is spiral welded pipe suitable for pressure pipelines?
A: Yes, when manufactured under API standards, spiral welded pipe can handle oil, gas, and water transmission pressure pipelines.
Q3: What coatings are available for corrosion protection?
A: We offer 3LPE, FBE, black paint, epoxy coal tar, and hot-dip galvanizing.
Q4: Can spiral welded pipe be used as foundation piling?
A: Absolutely. Its strength and large size make it perfect for pile foundations and structural columns.
Q5: What’s the maximum length per pipe?
A: Standard is 12m, but we can supply up to 18m or longer with special logistics arrangements.
