As a stainless steel pipe manufacturer, we still have a certain say in the various standards of stainless steel pipes. Today, Xiaobian has sorted out the relevant knowledge of stainless steel pipe length standards, thickness standards and brightness standards, hoping to help you. According to industry norms, the length of stainless steel pipe is generally 6 meters, the error is +10mm in this range, the length of seamless pipe is generally more, the length is mainly 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 to 9 meters, which has less impact on production costs. Therefore, users who buy stainless steel welded pipes should customize different lengths according to their needs.
The size of seamless pipe can meet the requirements, but the impact on production costs is obvious.

The thickness of the stainless steel pipe is generally produced according to the standard thickness, and the measured value within the tolerance range is the actual thickness. The thickness tolerance required by the national standard is ±0.3mm inside; The thickness tolerance of the general decorative tube is less than 25%, and the allowable range of product tube thickness error is ±0.05mm, including the thickness tolerance of the fine tube. Our stainless steel pipe is indicated by the actual thickness, and the actual thickness (thickness tolerance is 0.03mm) is indicated by the price.
Stainless steel pipe surface brightness
The stainless steel welded pipe material before forming is 2B surface stainless steel strip, and the surface of the stainless steel welded pipe after forming is light surface, which is commonly known as the wool surface in the industry, smooth and bright, showing metal primary color; On the basis of the light surface, the polishing equipment (180~600# polishing wheel) can obtain the polished surface (round sand/straight line), also known as the matte surface, bright surface and bright surface effect. Usually, the mirror effect of the stainless steel tube only indicates high brightness, and only the grinding and polishing of the stainless steel plate can achieve a true mirror. The surface treatment industry of stainless steel decorative pipes is generally divided into two kinds of wire drawing and bright surface, which is also suitable for the product needs of most customers. Some high end customers choose mirror stainless steel tubes to make more beautiful products. However, relative costs will also increase.
