Cold Drawn Seamless Steel Pipe

Home » Products » Cold Drawn Seamless Steel Pipe

The equipment for producing the cold drawn seamless steel pipe comprises two piercing production lines and six cold drawn production lines. They are mainly employed to produce hundreds of varieties of the product, such as full range of inner thread type, stainless type and more. With the outside diameter ranging from 4 to 530mm, our product has been widely used in miscellaneous structures, transportation for oil, gas and other fluid, boiler with medium and high pressure, heat exchanger, condenser, etc.

With the annual production capacity being up to 600000 tons, we have been the leading seamless steel pipe manufacturer in China. Having passed the certifications of ISO9000 and ISO9001 international quality control system, API 5L and API 5CT, our company has established a complete quality assurance system. Meanwhile, we have received production license for boiler pipe with low and medium pressure from the state related institution. Besides that, our product is awarded as Shandong Province Famous Brand and qualified product in national product quality supervision by China Association for Quality Inspection.

Now, we have formed a sound development pattern with reasonable product structure, high product quality and advanced technological monitoring method. The products of our company are founded not only throughout the country but also in foreign market such as Iran, India, Singapore, Germany, Italy, America, Korea, Canada, etc. We'd like to seek a more promising future with customers and the related enterprises all over the world.

This series of cold drawn seamless steel pipe is produced under normal temperature with the process of cold drawing. Compared with hot forming method, this kind of processing method can get much excellent precision and surface roughness. So, the cold drawn product is suitable for the customers having high requirements for dimension accuracy and visual effect. For there is no need for heating process, the production efficiency of the cold drawn product is comparatively high. But referring to the mechanical properties such as torsional strength, the steel tube without being heat treated performs not so well. Thus, customers, needing the product with relatively high mechanical properties, can choose our hot rolled product.

The minimum outside diameter of our cold drawn seamless steel pipe can be 4mm with high precision and the maximum size is 530mm. With six cold drawing production lines available, we can produce the product for 600000 tons per year. Thus, we can still ensure timely delivery even for the customers with large quantity of the product.

As a China-based cold drawn seamless steel pipe manufacturer and supplier, Liaocheng Yaxinda Steel Pipe Co.,Ltd. also offers hot rolled seamless steel pipe, honed tube, machining parts, and welding electrodes, among others.
