LSAW Structural steel pipe should meet specific strength and formability. The strength of steel pipes in these applications is an important design criteria.

LSAW Pipe piles are commonly used in deep foundations and transfer the loads from building to stronger soil layers deep underground. The loads are resisted through surface friction and point bearing. Pipe can be driven either open-ended or closed-ended, with points or plates. If driven with plates, the pipes can then be filled with concrete to improve strength to the pile. Pipe piles range in size from several inches to several feet in diameter and can be easily spliced to create piles hundreds of feet in length.

ASTM A252 steel piling pipe is grouped into three categories which are seamless pipe type, ERW welded pipe type and SAW type. SAW type pipe include longitudinal SAW(LSAW) and helical or spiral SAW(SSAW). It is manufactured in high quality steel Gr.1, Gr.2 and Gr.3. In the meantime, the raw materials such as X52, X65, X70 can also be specified by our customers. For the SSAW type, the max. length up to 85 meters is available and its size up to 120". For the longitudinal SAW type, the standard length is 6 or 12 meters and the size ranges from 18" to 100".
