SSAW welded steel pile Pipe ASTM A252 standards 1016x25.4x50000mm mm

SSAW welded steel pipes are often driven to function as end bearing or friction piles. The pipe piles may be driven either open ended or close ended. When the driving end of the pipe is left open, (without any driving point) it is called open end pile. Open ended piles are usually driven to penetrate rock or hard pan. As the open ended piles are sunk in the ground, the soil inside the pipe is cleaned out by means of compressed air, water jet etc simultaneously. When the pipes have been driven to the required depth, they are cleaned from inside and filled with concrete.

In case of closed end piles, the driving end of each pipe is closed by welding a conical steel or cast iron shoe to the pipe end. In this case also, after driving, the hollow space inside the pipe is normally, filled with concrete. The diameter of the pipes used for piling varies from 25 cm to 120 cm and their shell thickness varies from 8 mm to 12 mm The use of this type of pile for depths of 30 in or more is quite common.

Steel pipe pile is a most recommend piling material for sea port constructions, yard buildings. It has been widely used in sea works or marine works, to create the tough foundations. Other than this, typical uses also as under buildings, bridges, and structural constructions. More details uses as below list:

Onshore and offshore constructions
Marine foundations / constructions
Tower building
Railway, highway construction
Dock yard construction
Sea works, marine works
Oil and gas filed fundations
Structural support in special buildings
