Two possibilities for the formation of surface defects of spiral steel pipes
There are two possibilities for the formation of surface defects of spiral steel pipes: one is that the material itself is not plastic enough during the deformation process, resulting in cracks and external folds; the other is that the surface oxidation of the material causes ...Read more -
Inspection standards and welding control issues of thick-walled steel pipes
Through observation, it is not difficult to find that all thick-walled steel pipes, hot-expanded pipes, etc. are produced with strip steel as the production material. The pipes obtained by thick-walled welding on high-frequency welding equipment are called thick-walled steel p...Read more -
About the characteristics and uses of the industrial straight seam steel pipes
First, the characteristics of straight seam steel pipes: Straight seam steel pipes generally refer to the use of special processes to treat ordinary steel pipes, so that the steel pipes have excellent anti-corrosion capabilities. They are generally used for waterproofing, rust...Read more -
Thermal deformation and microstructure evolution of thick-walled welded steel pipes
First, thermal deformation and microstructure evolution of thick-walled welded steel pipes: Thick-walled welded steel pipes are a precipitation-strengthened nickel-based high-temperature alloy that is difficult to deform. They are similar in composition to the former Soviet Un...Read more -
Implementation standards and technological progress of straight seam steel pipes
Welded steel pipes, also known as welded pipes, are steel pipes made by welding steel plates or steel strips after curling and forming. The production process of welded steel pipes is simple, the production efficiency is high, the varieties and specifications are many, and the...Read more -
Reasons for sand eyes at the weld of spiral seam submerged arc welded steel pipe
Spiral steel pipe is made by bending the strip steel in a spiral direction through a coiling machine and then welding it through a capacitor double-sided submerged arc. In the process of spiral steel pipe welding production, many galvanized channel steel situations such as lea...Read more -
Quality inspection methods commonly used in spiral steel pipes in industrial projects
The quality inspection methods of spiral steel pipes in industrial projects are as follows: 1 Judging from the surface, that is a visual inspection. The visual inspection of welded joints is a simple procedure with a wide variety of inspection methods. It is an important part ...Read more -
Tips for identifying inferior steel pipes
Fake steel pipes are prone to folding. Folding is a variety of fold lines formed on the surface of the steel pipe, and this defect often runs through the entire longitudinal direction of the product. The reason for the folding is that the inferior manufacturers pursue high eff...Read more -
How to solve the deformation problem of the industrial spiral seam submerged arc welded steel pipe
The spiral seam submerged arc welded steel pipe is rotated and drilled and begins to enter the soft formation. Under the action of the three-cone wheel, the drill bit first produces elastic shear deformation of the formation and then is removed under the pressure of the three-...Read more
