According to the production process, U-shaped steel sheet piles are divided into two types: cold-formed steel sheet piles and hot-rolled steel sheet piles. In engineering construction, cold-formed steel sheet piles are relatively cost-effective, and in engineering applications, the two types can be substituted for each other. So how are U-shaped steel sheet piles generally constructed?

Cold drawn seamless pipe has the advantages of no oxide layer on the inner and outer walls, no leakage under high pressure, high precision, high finish, no deformation after cold bending, no cracks in flaring and flattening, and anti-rust treatment on the surface.

The main parameters of welded pipe processing process include welding thermal output, welding work pressure, welding rate, tensor angle size, direction and size of the electromagnetic induction coil, and the direction of characteristic impedances. These parameters have a great impact on the development of welded pipe products, production efficiency, and production capacity of generator sets.

Seamless black steel pipe has the advantages of high pressure resistance and good toughness, which determines that it has a wide range of industrial applications, such as widely used in chemical and petroleum industries.

Among the common problems of seamless pipes, wall thickness difference and eccentricity take the first place.As the name suggests, it is the difference between the maximum wall thickness and the minimum wall thickness.

The construction process of PHC pipe pile includes the following five aspects: measuring and laying out line, measuring and placing pile position, vertical pile and pile insertion, straightness control and piling.
