Spiral Welded Pipe ASTM A252 Pipe in China

ASTM A252 Spiral Welded Pipe is manufactured via Submerged Arc Weld (SSAW) process, with stable structural performance, high strength and excellent corrosion resistance. It is specially optimized for Middle East's harsh working conditions (high temperature, desert sandstorm, marine salt spray) and widely used in deep foundation piling, bridge construction, port terminals, oil & gas auxiliary projects, and urban infrastructure in Saudi Arabia, UAE, Qatar, Kuwait, Oman, Iraq and other Middle East countries.

Standard: ASTM A53, ASTM A252, ASTM A139, ASTM A36, etc.

Material Grade: GR 1, GR 2, GR 3, GR.A, GR.B. (Customizable based on project load requirements).

Welding Type: Spiral Submerged Arc Welding(SSAW), Double-Sided Welding.

Surface Treatment: Black Paint, FBE (Fusion-Bonded Epoxy), 3PE Coating (Anti-corrosion for salt soil & marine environment, core option for Middle East market), corrosion resistant coating+cap.

Certification: API 5L+ASTM, ISO 9001, BV/SGS/TUV Third-Party Inspection, Full Material Test Certificate(MTC) Provided.

Out Diameter (OD): 8"-118" (219–3020mm) (Large diameter available for mega projects).

Wall Thickness (WT): 0.322"-1.602" (8.1–26.97mm) (Heavy wall options for deep piling & heavy load).

Length: as pet customer's requirement.

Superior Corrosion Resistance: Adapt to Middle East's marine salt spray, desert salt soil and high-temperature environment, extending service life of infrastructure projects.

High Strength & Bending Performance: Grade 2/3 options with excellent toughness, suitable for deep foundation piling and seismic zone projects (e.g.,coastal bridges, high-rises).

Stable Welding Quality: All pipes pass UT (Ultrasonic Testing), RT (X-ray Testing) and Hydrostatic Pressure Test, meeting strict Middle East project inspection standards.

Cost-Effective Large Diameter: Manufactured from steel coils, providing large-diameter pipes (over 1000mm) at competitive prices, perfect for port, bridge and oil & gas auxiliary projects.

Local Market Experience: Rich supply experience for Middle East countries, familiar with local customs clearance, logistics and project certification requirements (SASO, ESMA, etc.), ensuring on-time delivery.

◎  Deep foundation piling for high-rise buildings, commercial centers and government projects.

◎  Bridge, highway and airport infrastructure construction.

◎  Port terminals, marine works and coastal protection projects.

◎  Oil & gas auxiliary structures, seawater desalination project foundations.

◎  Retaining walls and urban drainage system infrastructure.

We strictly implement ASTM A252 standard in every production process, from raw material selection to welding, inspection and packaging. For Middle East customers, we provide Third-party inspection on-site, professional logistics arrangement, and after-sales technical support for installation and application. We have successfully supplied to many key projects in Saudi Arabia, UAE and Qatar, gaining high recognition from local buyers.
