Description

Seamless Rectangular Steel Tube

Seamless Rectangular Steel Tube is a carbon steel construction material with rectangular hollow cross-section, which is a cost-effective cross-section steel with less weight when compared with solid steel such as round steel with the same bending and torsion strength. 

The seamless rectangular steel tube produced by Yuantai Derun is widely used in construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation bracket, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, automobile chassis and other fields. Contact immediately.

Seamless Rectangular Tubes Advantage

1. High strength: Seamless rectangular tubes have uniform wall thickness, no welds, and are not easy to crack, so their strength is higher than welded square rectangular pipes, and they can withstand greater pressure and tensile forces, making them more versatile.

2. High precision: The production process for seamless rectangular tubes is relatively more precise, with high dimensional accuracy and more regular geometric shapes. It has obvious advantages in certain application fields that require precise dimensions, such as high-precision machinery, instrumentation, automotive industry, etc.

3. Strong corrosion resistance: The inner and outer surfaces of seamless rectangular tubes are smooth, without welds, and are not prone to the accumulation of corrosive substances and impurities, thus having good corrosion resistance. Pipelines widely used in the fields of chemical, petroleum, aviation, etc. for transporting corrosive media.

4. Uniform stress distribution: During the production and forming process of seamless rectangular tubes, the grain arrangement of the material is more compact, the internal stress distribution is more uniform, and it is not easy to produce welding heat affected zones and deformations, and has high strength.

5. Convenient construction: Seamless rectangular tubes are easy to install and do not require welding processes, making them more suitable for complex and limited environmental conditions. At the same time, seamless rectangular pipes can also be cold bent, which can be formed according to needs, reducing problems caused by heat treatment and heat affected areas.

Seamless Rectangular Steel Tube Manufacturing Process

Seamless Rectangular steel tube is made from seamless tube as the parent material, through the re-drawing or cold-drawing for production, which is also known as round to square. The main processing flow of Seamless Rectangular Steel Tube includes: Round Steel → Tube Billet → Inspection → Heating → Piercing → Diameter Setting → Hot Rolling → Flat Head → Inspection → Pickling → Ball Annealing → Cold Drawing → Molding → Flush Mouth → Inspection.

Seamless Rectangular Tube Coating

At Yuantai Derun, in order to prevent seamless rectangular steel tube from rusting and being corroded, we can request a surface treatment for your seamless rectangular tube, common surface treatments include oiling, painting, hot dip galvanizing and so on. If you also need coating service, please send your request now.
