304 stainless steel pipe | What is the length standard?

As a stainless steel pipe manufacturer, we still have a certain say in various standards for stainless steel pipes. Today, Xiaobian has compiled relevant knowledge on the length standards, thickness standards, and brightness standards of stainless steel pipes, hoping to be helpful to you. According to industry standards, the length of stainless steel pipes is generally 6 meters, with an error of+10mm. Within this range, the length of seamless pipes is generally more, mainly ranging from 5 to 7 meters. Companies producing stainless steel pipes can customize different lengths according to different customer requirements. Relatively speaking, the size of stainless steel welded pipes can be 3-9 meters, which has little impact on production costs. So, users who purchase stainless steel welded pipes need to customize different lengths according to their own needs.

The size of seamless pipes can meet the requirements, but it has a significant impact on production costs.

The thickness of stainless steel pipes is generally produced according to standard thickness, and the measured values within the allowable tolerance range are the actual thickness. The thickness tolerance required by national standards is ± 0.3mm internal; The thickness tolerance of general decorative tubes is less than 25%, and the allowable range of product tube thickness error is within ± 0.10mm of the thickness tolerance of precision tubes, which is ± 0.05mm. Our stainless steel pipes are expressed based on actual thickness, and the actual thickness (with a thickness tolerance of 0.03mm) is marked with the selling price.

Surface brightness of stainless steel pipes

The material of the stainless steel welded pipe before forming is 2B surface stainless steel strip, and the surface of the stainless steel welded pipe after forming is a smooth surface, commonly known as a rough surface in the industry, which is smooth and bright, with a metallic primary color; On the basis of a smooth surface, polishing equipment (180~600 # polishing wheels) can obtain a polished surface (round sand/straight line), also known as matte surface, bright surface, and bright surface effects. Usually, the mirror effect of stainless steel pipes only represents high brightness, and only the grinding and polishing of stainless steel plates can achieve true mirror effect. The surface treatment industry of stainless steel decorative pipes is generally divided into two types: wire drawing and bright surface, which are also suitable for the product needs of most customers. Some high-end customers choose mirror faced stainless steel pipes to create more beautiful products. However, the relative cost will also increase.
