[Stainless steel tube] Stainless steel tube length standard, thickness standard and stainless steel tube brightness 2019-09-04 As a stainless steel tube manufacturer, the editor still has a certain say in the various standards of stainless steel tube. Today I have compiled relevant knowledge about stainless steel tube length standards, thickness standards and brightness standards for everyone, and I hope it will be helpful to everyone. The length of the stainless steel tube is generally 6 meters in accordance with the industry specifications, and the error is within +10mm. The length of the seamless tube is generally variable, and the length is mainly 5 to 7 meters. According to different customers According to requirements, companies producing stainless steel pipes can customize different lengths according to customer requirements. Relatively speaking, stainless steel welded pipes can be 3 to 9 meters in length, which has little impact on production costs. Therefore, customers who purchase stainless steel welded pipes can customize different lengths according to their needs. The length of the seamless pipe can be as required, but this may have a significant impact on the production cost.  The thickness of the stainless steel pipe  The thickness of the stainless steel pipe is generally produced according to the standard thickness, and the measured value of the thickness within the allowable tolerance range is the actual thickness. According to the national standard, the thickness tolerance of the tube is within ±0.3mm; the thickness tolerance of the general decorative tube in the industry is less than 25%, the thickness tolerance of the product tube is within ±0.10mm, and the thickness tolerance of the precision tube is within ±0.05mm.   Our stainless steel pipes are expressed according to the actual thickness, and the price is marked according to the actual thickness (thickness tolerance is 0.03mm) unless otherwise specified. The surface brightness of the stainless steel pipe is made of 2B surface stainless steel coil before forming. The surface of the stainless steel welded pipe after forming is smooth, which is also commonly called matte in the industry. This surface is smooth and bright, showing the primary color of metal; on the smooth surface The stainless steel welded pipe is processed by polishing equipment (180~600# polishing wheel) to obtain a matte surface (round sand/straight wire), also known as matte, bright and high-gloss, and mirror surface effects on the basis of polishing equipment. Under normal circumstances, the mirror effect of the stainless steel tube is only an expression of high brightness, and only the grinding and polishing of the stainless steel plate can achieve a true mirror surface. The surface treatment industry of stainless steel decorative pipes is generally divided into two types: wire drawing and bright surface, which are currently suitable for the product needs of most customers. Some high-end customers choose mirrored stainless steel pipes to make more beautiful products. However, the relative cost will also increase. The surface treatment of stainless steel pipes also includes cleaning and polishing/protection/pickling passivation/degreasing and dust removal/washing and drying, etc. The above is some common sense of stainless steel pipe length standards, thickness standards and brightness of stainless steel pipes compiled by the stainless steel editor of stainless steel pipe manufacturers. hope that it can help us.
