Spiral steel pipe for bridge piling

Spiral welded steel pipes for bridge piles are made of hot-rolled steel strip coils as pipe blanks, often warmed and spirally formed, and made by double-sided submerged arc welding or high-frequency welding. They are used for foundation piles in civil construction structures, docks, bridges.

Spiral steel pipe for bridge piling is an indispensable material in bridge construction. It has the characteristics of high strength, corrosion resistance, and excellent tensile and compression resistance. This kind of steel pipe is made by a plate rolling machine. It is rolled into a spiral shape multiple times and seam welded at the edge of the plate to form a long pipe-like structure. Spiral steel pipes are widely used in bridge piling because of their simple production and convenient construction. The use of spiral steel pipe piling can greatly shorten the construction period and reduce construction costs, and due to its strong tensile and compression resistance, it can enhance the load-bearing capacity of bridge piling.

Before construction, spiral steel pipes will undergo strict physical and chemical tests to ensure that their quality meets standards. Spiral steel pipes will also use a reasonable cooling system during the production process to avoid internal cracks and improve the quality of the steel pipes in many aspects. In terms of production control, attention will be paid to the control of heating temperature, sufficient holding time and adjustment of roller speed, all of which are to improve the plastic toughness and overall quality of thick-walled spiral steel pipes.

In addition, spiral steel pipes are also widely used in submarine piling, such as in the construction of bridges, docks, offshore platforms and other projects. The structural stability, corrosion resistance and ease of construction of spiral steel pipes make them the preferred material for submarine piling. It can be connected through threaded connection or welding to improve construction efficiency.

In general, spiral steel pipes for bridge piling play an important role in bridge construction and other marine engineering projects due to their many advantages, and with the development of technology, their application scope and role will become larger and larger.
