Application of straight seam steel pipe in piling
Steel pipe pile is suitable for the construction of the terminal in the terminal, the diameter range is generally between 400-2000mm, the most commonly used in 1800mm. Shaped steel pipe can better adapt to the special conditions of use, save metal and improve the productivity of spare parts manufacturing. Its widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, textile and boiler manufacturing and so on. Production of special-shaped pipe methods are cold drawn, welding, extrusion, hot rolling, which cold drawn method has been more widely used. Utility model in the cofferdam when the steel pipe pile between the use of each other was curved or round shape. It can play the role of water, earth, sand and so on. The utility model has the advantages of novel design, simple structure, convenient use, easy overlap and good sealing. Including cross-sectional profile non-circular, and other wall thickness, variabl...
