Product Overview
Steel pipe piles are open or closed-ended tubular steel piles used for deep foundation support in weak soils, marine structures, bridges, and heavy industrial equipment. Texin Steel supplies both spiral welded (SSAW) and longitudinal submerged-arc welded (LSAW) pipe piles in diameters from 219mm to 3000mm, with wall thicknesses from 5mm to 25mm.
Key Advantages
- Wide Size Range: 219-3000mm OD, 5-25mm WT, any length โ custom cut to project requirements.
- Two Weld Types: SSAW (spiral submerged-arc) for larger diameters; LSAW (longitudinal) for uniform stress distribution.
- High Steel Grades: Q235B, Q345B, Q355B, Q420B, Q460C โ matching GB/T, ASTM, API, or GOST standards.
- Ready for Driving: Ends bevelled (30ยฐ or 37.5ยฐ), driving shoes or closure plates optional.
- NDT Tested: 100% UT weld inspection; hydrostatic testing available on request.

Texin supplies steel pipe piles for infrastructure projects worldwide. Our SSAW pipes are used in port expansion projects across Southeast Asia, while LSAW piles are specified for bridge foundations in Africa and the Middle East.
FAQ
1. What is the difference between SSAW and LSAW pipe piles?
SSAW (spiral) has a helical weld and is more economical for large diameters. LSAW (longitudinal) has a straight seam with more uniform stress โ preferred for dynamic driving loads.
2. Do you provide pile driving accessories?
Yes โ driving shoes, closure plates, stiffener rings, and splice welding sleeves can all be supplied.
3. Can you supply piles with EAC/GOST certification?
Yes. All piles can be supplied with GOST 10706 compliance documentation and EAC certificate for CIS markets.
