During the forming process of the spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and the surface has no scratches. The processed spiral steel pipe has more flexibility in the diameter and wall thickness size range, especially in the production of high steel g

After the oil casing adopts this heat treatment method, the impact toughness, tensile strength, and anti-destruction performance of the oil casing can be effectively improved, and the good value in use can be guaranteed. Oil casing is a necessary pipe for drilling oil and natural gas, and it needs t

Spiral steel pipe maintenance medium transportation is one of the important materials. Spiral steel pipe is the anti-corrosion of the outer wall of high-grade steel oil, gas, water, and heating pipelines, and the durability of the spiral steel pipe is improved. The durability of the spiral steel pip

3PE anti-corrosion steel pipe is a high-level anti-corrosion steel pipe. It is composed of primer + glue + PE three-layer anti-corrosion. It has high corrosion resistance and high wear resistance. Well, once the anti-corrosion layer is destroyed, it will corrode quickly, and the parent body of the 3
