Both straight seam steel pipe and spiral steel pipe are types of welded steel pipe, but straight seam pipe is welded using high-frequency welding and submerged arc welding, while spiral pipe is welded using submerged arc welding. These pipes are widely used in national production and construction.

Welded steel pipe and spiral steel pipe have many differences due to their different production processes.

The production process for straight seam welded pipe is relatively simple. The main production processes are high-frequency welding and submerged arc welding. Straight seam pipe boasts high production efficiency, low cost, and rapid development.

Spiral welded pipe is generally stronger than welded pipe. Its main production process is submerged arc welding. Spiral steel pipe can be produced from billets of the same width to produce pipes of different diameters, and can even produce larger diameter pipes from narrower billets. However, compared with straight seam pipes of the same length, the weld length increases by 30~100% and the production speed is lower. Therefore, smaller diameter welded pipes mostly use straight seam welding, while large diameter thick wall double-sided submerged arc welded straight seam steel pipes mostly use submerged arc welding.

Double-sided spiral seam submerged arc-welded steel pipes are produced using an automated production line, which can achieve continuous and high-speed welding. This production method not only improves production efficiency but also reduces worker intensity.
Double-sided spiral submerged arc-welded steel pipe utilizes a submerged arc welding process, which offers advantages such as high welding speed, deep penetration, and high weld quality. At the same time, by welding inside the pipe, the influence of the external environment on the welding quality can be avoided.
Since double-sided spiral seam submerged arc welded steel pipes use high-strength steel strips as raw materials, they have good mechanical properties such as tensile strength, yield point and elongation, and can meet various engineering needs.
Double-sided spiral seam submerged arc-welded steel pipes are widely used in various projects, such as bridges, buildings, pipelines, etc. Its excellent performance and good adaptability enable it to maintain a stable working state in various harsh environments.

Color coated steel plate: refers to color coated steel plate, which is a steel plate with an organic coating. Color steel plates are divided into single plates, color steel composite plates, floor decking plates, etc. It is widely used in the walls and roofs of large public buildings, public factories, mobile houses, and integrated houses.

Corrugated sheet, also known as profiled sheet, is made of color-coated steel sheet, galvanized sheet and other metal sheets that are cold-bent into various corrugated sheet shapes through roller pressing. It is suitable for industrial and civil buildings, warehouses, special buildings, roofs, walls, and interior and exterior wall decoration of large-span steel structure houses. It has the characteristics of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fire resistance, rain resistance, long life and maintenance-free, and has been widely promoted and applied.

1. The two coatings are different. Color-coated steel plates are organic coatings, while corrugated plates are galvanized coatings.

2. The lifespan of the two types is different. Color-coated steel plates are prone to rust. To maintain their beauty, they must be maintained every two years. Corrugated board is maintenance-free and has a long lifespan.
