Adjustment of the position of the high-frequency induction coil of the straight seam steel pipe:The excitation frequency of straight seam steel pipe is inversely proportional to the square root of capacitance and inductance in the excitation circuit or proportional to the square root of voltage and
At present, there are more and more types of straight seam steel pipes. With the rapid development of continuous strip rolling production and the advancement of welding and inspection technology, the weld seams continue to improve, the varieties and specifications of welded steel pipes are increasin
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. The normal service life is about 30 years. Well, once the anti-corrosion layer is damaged, it will corr
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 molten wire flux.During use, the principal stress direction of the thick-
1. Different pressure bearing capacity:The working pressure that the seamless steel pipe can generally withstand is within 20 kg, which is the safest use range. It is generally used for low-pressure fluids such as water, gas, and compressed air; seamless steel pipes can withstand ultra-high pressure
With the wide application of stainless steel pipes, people's requirements for them are getting higher and higher, and the processing technology has become diversified. Pickling is one of the processing techniques. Do you know why hydrogen embrittlement occurs in stainless steel pipes after pickling?
The wall thickness of the spiral welded steel pipe is uniform, it looks good, the force is uniform, and it is durable. The wall thickness of the spiral welded steel pipe is uneven, and the steel pipe is unevenly stressed. A phenomenon that easily occurs during the steel pipe rolling adjustment proce
High-pressure boiler steel pipe: mainly used to manufacture high-quality carbon structural steel, alloy structural steel, and stainless heat-resistant steel seamless steel pipe for steam boiler pipes with high pressure and above pressure. These boiler pipes work under high temperatures and high pres
