ERW Steel Pipe for bridge piling

Straight seam steel pipes for bridge piling are important materials for pile foundation construction in bridge construction. They usually need to have high strength and durability to adapt to the load-bearing requirements of the bridge.

Straight seam steel pipes for bridge piling are important materials for pile foundation construction in bridge construction. They usually need to have high strength and durability to adapt to the load-bearing requirements of the bridge. Here is some key information about straight-seam steel pipe for bridge piling:

Material and strength: Straight seam steel pipes are generally made of ordinary carbon steel with specific tensile strength and yield strength, such as tensile strength up to 402MPa and yield strength 235.2MPa, or selected according to design requirements.

Production process: Straight seam steel pipes can be divided into high-frequency straight seam steel pipes and submerged arc welded straight seam steel pipes according to the production process. Submerged arc welded straight seam steel pipes are divided into UOE, RBE, JCOE steel pipes, etc. according to their different forming methods.

Forming process: The manufacturing process of straight seam steel pipes includes plate detection, edge milling, pre-bending, forming, pre-welding and other steps. Among them, forming is to press the steel plate into a tube blank on the forming machine, and pre-welding is to use gas shielded welding for continuous welding.

Quality control: Straight seam steel pipes undergo multiple quality inspections during the production process, including ultrasonic inspection, X-ray inspection, hydrostatic testing, etc., to ensure the quality of the welds and pipes.

Anti-corrosion treatment: In order to improve the durability of straight seam steel pipes, they are usually anti-corrosion and coating treatments to adapt to different use environments.

Scope of application: Straight seam steel pipes are widely used in long-distance transmission pipelines such as natural gas, petroleum, chemical industry, electricity, heat, water supply and drainage, steam heating, pressure steel pipes for hydropower stations, thermal power generation, water sources, and engineering fields such as piling, bridges, and steel structures. .

Standards and markings: The production and use of straight seam steel pipes must comply with national standards, such as GB/T 30063-2013, etc., and each steel pipe will be marked for easy identification and tracking.

Technical requirements: The technical requirements of straight seam steel pipes include size, shape, weight, technical requirements, test methods, etc., all of which need to be carried out in strict accordance with relevant standards.

Economical: Due to its relatively simple process and high production efficiency, straight seam steel pipes are widely used in civil construction, petrochemical, light industry and other departments. They are mostly used to transport low-pressure fluids or be made into various engineering components and light industrial products.

Environmental adaptability: Straight seam steel pipes can also be customized according to the specific use environment to adapt to different soil conditions, temperature changes and other environmental factors.

In summary, straight seam steel pipes for bridge piling have been widely used in the construction of bridges and other infrastructure due to their high strength, good construction performance and reliability.
