Product detail PK diagram

1.Material raw material

RAW MATERIAL GUARANTEE

The raw materials for steel pipe manufacturing of the company come from Shougang Group, Baotou Steel Group, Hebei Iron and Steel Group, Cangzhou Longgang Equipment Manufacturing Co., Ltd., Rongcheng iron and steel, Jinxi iron and steel and other large-scale well-known steel manufacturing enterprises in the world.

The harm of inferior steel strip is very great

The raw materials of low-quality steel coils produced by some small steel mills are fake other steel mills. They are produced in violation of regulations, the composition is unqualified, and the formaldehyde exceeds the standard, which is very harmful.

2.Weld line

The steel pipe welds are tight without potential safety hazards

The steel pipe with tight welds is stronger and less potential safety hazards

Weld cracking

In the process of pipeline installation and construction, weld cracks are often encountered. If they are not found and repaired in time, there will be potential safety hazards

3.Rust or not？

No rusty steel pipe

Yuantai's steel pipe products are subject to strict anti-corrosion treatment and derusting treatment, which makes customers and buyers less worried

Rusty steel pipe products do great harm

Rusty steel pipe products do great harm, which not only affects the service life of steel pipe, but also affects the quality of the whole project

4.Are the dimensions accurate?

Precise size steel pipe

Yuantai's steel pipe dimensions are measured layer by layer and automatically processed by sizing machinery. At the same time, the steel pipe products are also accurately measured manually by the merchandiser, so that the size of each steel pipe is accurate, which saves customers worry and rest assured.

Inaccurate steel pipe

The steel pipe with inaccurate size will not only cause engineering accidents such as pipeline leakage and leakage, but also cause the failure of docking with third-party equipment, delaying the construction period and being unusable.

5.High wind resistance

High windproof steel pipe

The high windproof steel pipe is not only durable and not afraid of wind and rain, but also increases the weather resistance of iron tower and other projects to avoid the damage of the project in windy weather.

Low windproof steel pipe

The low windproof steel pipe basically has no weather resistance. In strong wind weather, it is easy to cause the tower and other engineering equipment to break and collapse, causing safety accidents.

Yuantai's steel pipe products meet the requirements of steel pipes all over the world, and also have authoritative official certification certificates all over the world
