Explore the details of DN900 spiral steel pipe

As a common type of steel pipe, spiral steel pipe is widely used in engineering construction, transportation pipelines, and other fields. As one of them, DN900 spiral steel pipe carries huge pressure and heavy responsibility. Let’s delve deeper into the mysteries of these giant pipelines!

A spiral steel pipe is a steel pipe made by rolling a steel plate into a tube shape and then welding it. It has high strength and stability and is suitable for transporting liquids, gases, and some solid particles. DN900 is one of the specifications of spiral steel pipes, with a diameter of about 900 mm, which belongs to the category of large-diameter steel pipes.

1. Manufacturing process of DN900 spiral steel pipe
Making a DN900 spiral steel pipe is not an easy task and usually includes the following steps:
- Raw material preparation: Select high-quality steel plates as raw materials, and ensure quality through physical and chemical performance testing.
- Plate bending: Bend steel plates into tubes to create spiral shapes.
- Welding: The edge of the steel plate is welded into a pipe shape through processes such as high-frequency submerged arc welding.
- Straightening: The welded steel pipe is straightened through a straightening machine to ensure the straightness of the pipe.
- Cutting: Cut long pipes into spiral steel pipes that meet the length requirements as needed.

2. Application fields of DN900 spiral steel pipe
DN900 spiral steel pipe is widely used in engineering construction. Common fields include:
-Transmission pipeline: used to transport oil, natural gas, water, and other media.
- Bridge supports: used as supports and connecting members in bridge construction.
- Building structure: as supporting columns, load-bearing components of buildings, etc.

3. Advantages and characteristics of DN900 spiral steel pipe
DN900 spiral steel pipe has some unique advantages compared to other steel pipes:
- High strength: Large-diameter spiral steel pipes have a strong ability to withstand pressure and are suitable for large-scale projects.
