We promise to accept any third-party testing. The sinosure factory is not afraid of any inspection. Welcome to make appointment to visit the factory.
Jianglin Steel Corporation specialized in stainless steel seamless pipe for more than 20 years. We have established good relations with other domestic steel mills, like Wu steel, Bao steel, An steel. By this way, we ensured our raw material best quality in market. Our products have been highly praised by our clients. From Europe, America, and Middle East, African and Southeast Asia. We will offer competitive product, and most comprehensive service to customers.
Obviously, seamless tubes refer to a kind of stainless steel tubes that has no welded seam. For achieving this purpose, Jianglin stainless steel utilizes extrusion process which means these seamless tubes are drawn from solid stainless steel billet, the next step is to extruded them into a hollow form. With thermal treatment, the billets can be formed into oblong circular molds, and then, they are manufactured into hollow shape in a piercing mill. The molds are elongated by mandrel rod while thermal ttreatment, also, the length of molds has been increased to twenty times after mandrel milling treatment.
Jianglin Stainless Steel manufactures our seamless tube firmly according to ASTM and international standards with multi types of sizes and grades. These seamless stainless steel tubes are manufactured through cold rolled and drawn process under the condition of annealing and pickle, the bright annealing finish is also allowed at Jianglin Stainless Steel. The hollow structure and an even surface allow our seamless tubes to withstand high temperature and high strength.
