Shandong Rigang Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after being rolled and formed. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of welds. Classified by production method: arc welded pipe, resistance welded pipe, (high-frequency, low-frequency) gas welded pipe, furnace welded pipe. The production process of straight seam welded pipe is simple, with high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrow billets can be used to produce larger diameter welded pipes, and billets of the same width can also be used to produce welded pipes of different diameters. However, compared to straight seam pipes of the same length, the weld length increases by 30-100% and the production speed is lower. Thick wall coil products include: large coil, large diameter thick wall coil, various materials thick wall coil, hot rolled thick wall coil, cold rolled thick wall coil, etc.
All welded pipes can be made into galvanized welded pipes, which can be found through product consultation on the homepage.

Shandong Rigang Cold rolled steel coil is made from hot-rolled steel coil as raw material, which is subjected to acid washing to remove oxide skin and then subjected to cold continuous rolling. The finished product is rolled hard coil. Due to the cold work hardening caused byStainless steel coil is a non-rusting metal product that is widely used in many fields due to its special properties in industrial production. The following is a brief introduction to the use of stainless steel coils in industrial production.

Shandong Rigang Supply Chain Management Co.,Ltd. Prestressed steel wire is a high-strength steel, widely used in construction, bridges, tunnels, water conservancy projects and other fields. It has excellent mechanical properties and durability, and can effectively improve the bearing capacity and seismic performance of structures.
   The material of the prestressed steel wire is mainly high-strength steel wire, and steel wires such as SWRH82B and SWRH77B are usually used. These steel wires have the characteristics of high strength, high toughness, high durability, etc., can withstand large tensile and bending forces, and also have good corrosion resistance and fatigue resistance.
   The manufacturing process of prestressed steel wire mainly includes drawing, steel wire stranding, prestressing processing and other links. During the drawing process, the steel wire is drawn and annealed multiple times to make it meet the requirements of high strength and high toughness. In the wire stranding process, multiple steel wires are twisted into one prestressed steel wire to improve its bearing capacity and seismic performance. During the prestressing process, the prestressed steel wire is tensioned to a certain level of prestressing, so that it generates compressive stress in the structure, thereby improving the bearing capacity and seismic performance of the structure.
