Steel Pipe Piles

Z-Shaped Steel Sheet Pile Advantages: 1)Flexible design with high modulus and mass ratio. 2)Higher moment of inertia increases the stiffness of sheet-pile wall and reduces displacement and defor-mation.

Steel pipe piles are composed of steel pipes, mortise and tenon grooves, and mortise and tenon pins. The left end pipe wall of the steel pipe diameter is vertically connected to the mortise and tenon groove, and the cross-section of the mortise and tenon groove is a square shape with one side opening. Reinforcement bars are provided on the side of the mortise and tenon groove. The right end pipe wall of the steel pipe diameter is vertically connected to the mortise and tenon pin, and the groove section of the mortise and tenon pin is an I-shaped shape.

Steel Pipe Piles

When the utility model is used for cofferdam, the steel pipe piles overlap with each other in an arc or circular shape. It can play a role in enclosing water, soil, and sand. This utility model has the advantages of novel design, simple structure, convenient use, easy overlap, and good sealing performance. Including non circular cross-sectional profiles, equal wall thickness, variable wall thickness, variable diameter and wall thickness along the length direction, symmetric and asymmetric cross-sectional profiles, etc. Such as square, rectangular, conical, trapezoidal, spiral tubes, etc.

Specially shaped steel pipes can better adapt to the special usage conditions, save metals, and improve labor productivity in component manufacturing. It is widely used in aviation, automobiles, shipbuilding, mining machinery, agricultural machinery, construction, light textile, and boiler manufacturing. The methods for producing special-shaped pipes include cold drawing, welding, extrusion, hot rolling, etc. Among them, the cold drawing method has been widely used.
