Thin-walled seamless steel pipes are made of steel ingots or solid tube blanks that are perforated into capillary tubes and then made by hot rolling, cold rolling, or cold drawing. Thin-walled seamless steel pipes play an important role in my country's steel pipe industry. Thin-walled seamless steel

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

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

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

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

1. Welded steel pipes for low-pressure fluid transportation (GB/T3092-1993) are also called generally welded pipes, commonly known as clarinet pipes. It is a welded steel pipe used for conveying water, gas, air, oil, heating steam, and other general lower-pressure fluids and other purposes. The wall

1. Reduce tripping time. It is about 5-10 times faster to change the drill bit with the wire rope than the traditional drill pipe trip;2. Save the cost of procurement, transportation, inspection, maintenance, and replacement related to drill pipes and drill collars;3. Because there is always a casin

1. The superior antistatic performance of hot-dip plastic steel pipe: through the addition of antistatic agents in the formula, the internal and external surface resistance can reach and exceed the relevant national industry standards.2. Flame retardant properties of hot-dipped plastic steel pipes:

The process of forging steel flanges generally consists of the following processes, that is, selecting high-quality steel billets for blanking, heating, forming, and cooling after forging. The process methods of forging steel flanges include free forging, die forging, and film forging. During produc

1. In the test results of straight seam steel pipes, if a certain item does not meet the requirements of the product standard, the unqualified ones should be picked out, and double the number of samples should be randomly taken from the same batch of straight seam steel pipes, and the unqualified it
