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

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

Steel is a non-combustible building material that is resistant to earthquakes and bending. In practical applications, steel can not only increase the load capacity of buildings relatively, but also meet the needs of architectural design aesthetics, and avoid the defects of concrete and other buildin

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

ASTM A335 P11 seamless steel pipe, seamless ferritic alloy steel pipe for high temperature, used for the heating surface of the high-pressure boiler, economizer, header, superheater, reheater, petrochemical industry pipe, etc. It belongs to the category of seamless steel pipes. The manufacturing met

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:

Welded steel pipe slag inclusions are slag that remains inside the weld. From a theoretical analysis, the main reasons for the slag inclusion in the submerged arc automatic welding seam are as follows: ①There are many inclusions in the raw materials (including base metal, welding wire, and flux); ②T
