A seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless pipes are thought to be able to withstand higher pressure, higher temperatures, higher mechanical stress and a corrosive atmosphere. It can be found in a wide range of applications such as in oil and gas, refinery, petrochemical, chemical, fertilizer, power, automotive, bearing, mechanical and structural.
它是空气，蒸汽，水和其他弱腐蚀性介质和酸，碱，盐等化学蚀刻介质腐蚀的耐钢管的抵抗力。又称耐酸不锈钢。它将越来越多的工程使用，并变得越来越受欢迎，并潜在展望。

首先，产品的壁厚较厚，更经济，实用，壁厚较薄，其加工成本将大幅上升;
Secondly, the process of the product determines its limitations, the low accuracy of the general seamless tube: non-uniform wall thickness, the appearance of low brightness tube, the high cost of fixed length, and within the appearance of pitting, black spots difficult to remove; Third, the detection and plastic must be offline processing. So it is at high pressure, high strength, the mechanical structure timber reflects its superiority.
The corrosion resistance of stainless steel seamless pipe depends on the alloying elements contained in the steel. Chromium is the basic elements of corrosion resistance for the stainless steel, about 12% the amount of chromium in the steel, chromium and oxygen role in the corrosive medium, the steel surface to form a thin oxide film (passive film) matrix can prevent the steel from further corrosion. Removing chromium, stainless steel seamless pipe commonly used alloying elements there are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of the various uses of the organization and performance of stainless steel.
