Spiral pipe (SSAW) is a welded pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submerged arc welding process. How to increase the stability of spiral steel pipe 1) Small and medium-sized steel bars, wire rods, steel bars, medium-caliber steel pipes, steel wires, and wire ropes can be stored…
Read MoreSpiral pipe is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. It can be made with a narrower strip Steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness….
Read MoreCritical components of alloy steel and thick parts must be preheated before welding. The purpose of preheating the spiral steel pipe before welding is as follows: (1) Preheating can slow down the cooling rate after welding, make hydrogen diffuse in the weld metal and escape, and avoid cracking caused by hydrogen. It can also reduce the degree of hardening…
Read MoreEveryone knows that when we transport all kinds of things, we need to check carefully, especially large-scale materials, which need to be checked two or three times before entering or leaving the warehouse. So how should the anti-corrosion spiral steel pipe be checked when entering and leaving the warehouse? What should be paid attention to in its transportation and…
Read MoreSpiral welded pipe (ssaw) is a kind of steel pipe that combines low-carbon and environmentally friendly alloy structural steel and low-alloy structural characteristics into pipe material and electric welding. How can the reliability of the spiral pipe be improved in the process of adoption? When we store it, we need to ensure the upper block and the lower pad,…
Read MoreSpiral welded pipes (SSAW) for water conservancy projects are generally spiral welded steel pipes with relatively large diameters, because the water passing through per unit time is large, which can greatly improve work efficiency. Since the inner wall of the spiral steel pipe is constantly washed by water, the inner wall is generally not treated with anti-corrosion treatment, but…
Read MoreSpiral pipe (SSAW) is a spiral seam carbon steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. It is mainly used in water supply engineering, petrochemical, chemical, electric power, agricultural Fluid transportation in the fields of irrigation and municipal buildings: water supply, drainage, sewage treatment…
Read MoreWhen making the anti-corrosion spiral steel pipe (SSAW), the inner and outer surfaces of the spiral steel pipe need to be sandblasted first, and then the inner wall is coated with primer, after the primer is dried, the intermediate paint is applied, and the intermediate paint is dried before applying the topcoat. After the inner wall is finished, the…
