What about Wuxi Peize Steel Pipe Co., Ltd.?

Answer; How about Wuxi hexagonal steel pipe?

Wuxi hexagonal tube hexagonal steel tube stainless steel hexagonal tube manufacturer? The overall market mentality is cautious and empty, and the scratches caused by human errors are serious: in the process of hoisting, transportation and structural production, the scratches caused by human errors such as bumping, procrastination and knocking are serious, which increases the difficulty coefficient of metal surface treatment and is also the key reason for rust after solution.

7 Mechanical equipment elements: The scratches and folds produced in the whole bending process of aluminum profiles, plates and sheet metals are also the key reasons for rust after solution.

8 Other factors: In the whole process of purchasing and storing stainless steel plate raw materials, the bumps and scratches caused by the whole process of hoisting and transportation are also serious, which is also one of the reasons for rust.

Wuxi hexagonal tube hexagonal steel tube stainless steel hexagonal tube manufacturer? Widely used in fluid mechanical transportation, crude oil, chemical plants, machinery and equipment. At present, the key of its production and processing technology in the market is cold drawing or cold binding plus aging treatment, and the external economic institution is mainly martensite. When choosing stainless steel seamless pipe, we should pay attention to the following aspects:

First look at the appearance. The internal and external surfaces of high-quality hexagonal steel pipes should be smooth, without cracks, expansion, scarring and other defects. The passivation film for pickling passivation on the inner and outer surfaces of seamless steel pipe should be detailed, and the surface of seamless steel pipe should have clear and comprehensive barcode of commodity information.

Second, measure the area. Relevant codes have provisions on the length, bending degree, different concentricity, uneven wall thickness and edge appearance design of hexagonal steel pipes. The hexagonal steel pipe can be placed on a flat road surface, and the hexagonal steel pipe can be turned over to observe the size and change of the gap between the seamless steel pipe and the road surface. Both sides of the standard seamless steel pipe should be perpendicular to the center line, and the wound should be burr-free.
