Our company has complete production equipment and advanced production technology. In order to ensure quality, the group company strictly implements: version quality management system equipped with advanced online ultrasonic, optical industrial TV, manual ultrasonic, Hydrostatic testing machines, universal material testing machines and other equipment implement the principle of combining random inspections, mutual inspections and full inspections on products to strictly control quality and prevent even one unqualified product from leaving the factory. In particular, we have mastered the production technology of diameter-grade spiral steel pipes, which is already at the leading level in the international industry. It can produce double-sided submerged arc welded steel pipes with diameters from Φ to Φ and wall thicknesses of - and various materials and steel grades - and comply with /- standards, .- standards and
standards. The registered trademark "Wuzhou" has been recognized as a famous trademark in Hebei Province by the Hebei Provincial Administration for Industry and Commerce. "The products are widely used in long-distance transportation pipelines such as natural gas, petroleum, chemicals, electricity, heat, water sources, etc. #Features of spiral steel pipes: The production process of straight seam welded pipes is simple, the production efficiency is high, the cost is low, and the development is rapid. The strength of spiral welded pipes is generally higher than Straight seam welded pipes can use narrower billets to produce welded pipes with larger diameters. Welded pipes with different diameters can also be produced from billets of the same width. However, compared with straight seam pipes of the same length, the weld length is increased by ~% and the production speed is slower. Low. Therefore, most of the smaller diameter welded pipes use straight seam welding, while the large diameter welded pipes mostly use spiral welding. With the purpose of quality, technology and development, we provide all-round services to customers throughout the entire process. New and old customers are welcome to call us to discuss business!
