Spiral Submerged Arc Welded Steel Pipe

SSAW (Spiral Submerged Arc Welded) steel pipe is the backbone of large-scale infrastructure. Manufactured by forming hot-rolled strip steel into a spiral shape and welding the seams using double-sided submerged arc technology, these pipes offer exceptional structural integrity and cost-efficiency for long-distance pipelines.
At Rayoung, we combine decades of manufacturing expertise with rigorous quality control to deliver SSAW pipes that withstand high pressure and harsh environmental conditions. Whether for water transmission, structural piling, or the oil and gas industry, our pipes are engineered to exceed international standards.

Global Applications

Our SSAW steel pipes are trusted by engineers worldwide for:

• Water Supply Systems: Large-diameter mains and municipal drainage.
• Piling & Foundations: Bridge piers, port construction, and high-rise building foundations.
• Energy Transport: Low-pressure gas pipelines and thermal power plant circulation.
• Structural Projects: Heavy-duty steel columns for stadiums and airports.

FAQ

Q: Can SSAW pipes be used for high-pressure gas transmission?
A: While SSAW is excellent for water and low-to-medium pressure gas, for ultra-high-pressure gas mains, we recommend checking the specific API 5L PSL2 requirements which our factory can also accommodate.
Q: What is the maximum diameter you can produce?
A: We currently produce up to 3500mm OD, making us one of the few suppliers capable of supporting massive marine piling projects.
Q: How do you prevent corrosion for underground use?
A: We offer 3PE (Three-Layer Polyethylene) and FBE (Fusion Bonded Epoxy) coatings, which can extend the service life of the pipe to over 50 years in soil.
