Operating stainless steel tube, specifications: OCrL8Ni9 (304), 1Cr18Ni9Ti (321), OCr23Ni13, AISI 304.316 L, OOCr17Ni14Mo2, through the efforts of the past decade, the company has become a large-scale steel pipe, Carbon Steel sales base, he has major national plant boiler plants, petroleum, chemical, Machinery and other enterprises have established steady supply relationships, integrity management companies to follow, true and quality service to the purpose, won the users, and expand the market, and established an extensive sales network, which have a certain reputation. The same time, the company also operates various types of special steel, steel tubes and stainless steel tube, high-pressure steel pipe, seamless steel tubes, and so on. Apart from the special pipe is outside the pipe cross-section shape of the Seamless Steel Tube customers. By the pipe cross-section of different shape and size can be divided into pipe wall thickness, etc. (codenamed D), Pipe wall thickness range (codenamed BD), the variable-diameter pipe (code-named BJ). Pipe special widely used for various structural components, tools and machinery parts. And the pipe, the pipe usually has a special greater moment of inertia and section modulus, a greater bending resistance capacity, can greatly reduce the structural weight, save steel.
