As a consumer, what is more intuitive to see is the surface brightness of stainless steel pipes. The stainless steel decorative pipe is made of 2B stainless steel coil before molding. The surface of the stainless steel welded pipe after molding is smooth. It is also commonly known in the industry as a matte surface. This surface is smooth and shiny, showing the original color of the metal. After processing by the polishing equipment (180 ～ 600 # polishing wheel), the matte surface (round sand / straight wire) can be obtained, also known as matte surface, bright surface and highlight and mirror surface effect.
Under normal circumstances, the mirror effect of stainless steel tubes is only a sign of high brightness. Only the grinding and polishing of stainless steel plates can achieve a true mirror surface. The surface treatment industry of stainless steel decorative tube is generally divided into two types: wire drawing and bright surface, which is also currently 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 also increase.
According to industry norms, the length of 304 stainless steel pipe is generally 6 meters. The length standard of 304 stainless steel pipe manufacturer Primesteelpipe stainless steel is based on production requirements +0.5 cm, which cannot be reduced or exceeded. According to the requirements of different customers, companies producing stainless steel pipes can customize different lengths according to customer requirements. In contrast, stainless steel welded pipes can be fixed to 3-9 meters in length, which has a small impact on production costs. Therefore, customers who purchase stainless steel welded pipes can customize different lengths according to their needs.
The thickness of 304 stainless steel pipe is generally produced in accordance with the standard thickness. The measured value of the thickness within the allowable tolerance range is the actual thickness. According to the national standard requirements, 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 ± 0.05mm.
