Thick-walled spiral steel pipe is a method of arc welding under the flux layer, which is formed by using the heat generated by the arc burning between the flux and the welding wire under the flux layer, the base metal, and the melting wire flux.In the process of use, the principal stress direction o
At present, the welding methods of stainless steel welded pipes used in the industry mainly include argon arc welding, high-frequency welding, plasma welding, and laser welding. Several welding methods have their characteristics. At present, the most used are argon arc welding and high-frequency wel
Seamless Steel Elbow: Steel Elbow is a type of pipe fitting used in pipe bends. Among all the pipe fittings used in the piping system, the proportion is about 80%. Usually, different forming processes are selected for steel elbows of different materials or wall thicknesses. Commonly used seamless st
The first may be due to the stress of the spiral seam submerged arc welded steel pipe. That is, the residual stress and welding stress after the steel pipe is formed. Secondly due to the presence of hydrogen. If the flux is not dried enough, the preheating temperature is not sufficient or the prehea
How does the spiral welded pipe need to be anti-corrosion? This is also a very important part of the application of spiral steel pipes in daily projects. Extending the daily life of the spiral steel pipe is also the most important focus of the customer for the project. The following is the anti-corr
The welding seam of the spiral steel pipe is longer than that of the straight seam steel pipe. If the pipe length is L, the welding seam length is L/cos(θ). The vast majority of steel pipe defects are concentrated in the weld and heat-affected zone. The long weld means that the probability of defect

When purchasing steel pipes, many customers often ask us which steel pipe is more suitable for spiral welded steel pipe and welded steel pipe. In fact, in many cases, the customer does not inform the specific situation of the project, and we cannot make relevant recommendations. However, here are so
①Advantages of material propertiesAs the name suggests, the thin-walled stainless steel water pipe is made of stainless steel. The strength of stainless steel is 3 times that of copper pipe and 8 to 10 times that of PPR pipe. It can withstand the impact of high-speed water flow at 30 meters per seco
