Tianjin Xinyue Steel Group is located in Tianjin Industrial Zone, near Tianjin Port. Xinyue is one of the major large-scale steel pipe enterprises in China, integrating steel pipe production, inventory and domestic and foreign sales. At the same time, we have several production base of ERW steel tubes, SSAW steel tubes, LSAW steel tubes, SMLS steel tubes, scaffolding and couplers. In order to better serve customers, we have been constantly breakthrough and learning on the professional road.

Today, let's know about the three common problems of seamless thick wall steel tubes. I believe these are also problems encountered by many customers when purchasing

1.Eccentric

As long as it is seamless steel pipe, there will be non concentricity phenomenon, which is mainly generated during perforation, which is unavoidable. Compared with the general wall thickness seamless pipe, the non concentricity phenomenon will be more serious , the thicker the wall thickness, the greater the eccentricity.

The eccentricity of steel pipe is too large, customers need to reserve more allowance for machining, which wastes materials and labor, and the product cost rises directly. Our factory has a professional thick wall seamless steel pipe piercing equipment, 30 years of rich technical experience, which can control the seamless pipe eccentricity within a reasonable range.

2. Uneven Hardness

Thick wall seamless steel pipe is more likely to leads uneven hardness of inside and outside, which is mainly related to heat treatment. This uneven hardness will lead to unqualified products after the customer's subsequent processing process, or even lose the customer.

Xinyue factory has professional heat treatment equipment, and the steel pipe is fully heated in the heat treatment process, so that the hardness of the steel pipe is consistent inside and outside, and the product quality is guaranteed.

3.Poor inner hole finish

For thick wall seamless steel pipe, especially the inner hole, the smaller the inner hole, the thicker the wall thickness. In the production process, it is more likely to cause defects such as pits, pits and so on.

Xinyue has solved this problem, and can customize the finish requirements of inner hole according to the later product requirements of customers, so as to provide customers with high cost-effective seamless steel pipe.

We have been working hard to serve every customer!

Xinyue people sincerely look forward to working with you!
