Surface treatment method of anticorrosive spiral steel pipe1. The surface of the anticorrosive spiral tube is cleaned with solvents and emulsions. Remove the organic matter on the surface of the spiral tube, but it cannot remove the surface rust, oxide scale, welding flux, etc.2. Use a wire brush, s
What are the main steel pipe fittings?1. The steel pipe fittings used to connect the pipes are: flanges, unions, pipe clamps, clamps, clamps, hose clamps, etc.2. Steel pipe fittings that change the direction of the pipe: elbows, elbows.3. Steel pipe fittings for changing the pipe diameter: reducing
The guaranteed method of the wall thickness accuracy of the straight seam steel pipe1. Tube billet heatingThe heating should be even, and the rapid rise and fall of the temperature should be avoided. The temperature of each rise and fall should be steady and slow, and the temperature of the rise and
Purchase situation of straight seam steel pipeThe nominal diameter of the welded pipe is 6~150mm, and the nominal wall thickness is 2.0~6.0mm. The length of the welded pipe is usually 4~10 meters. The surface of the steel pipe should be smooth, and no defects such as folding, cracks, delamination, l

Advantages of 304 stainless steel pipe①Material performanceAs the name suggests, the thin-walled stainless steel pipe is made of stainless steel. The strength of stainless steel is 3 times that of copper pipes and 8-10 times that of PPR pipes. It can withstand the impact of high-speed water flow of
Thick-walled steel pipes, the steel pipe whose outer diameter to wall thickness ratio is less than 20 is called thick-walled steel pipe. Mainly used as petroleum geological drilling pipes, cracking pipes for the petrochemical industry, boiler pipes, bearing pipes, and high-precision structural pipes
Process characteristics of galvanized steel pipe1. Optimization of sulfate zinc platingThe advantages of sulfate galvanizing are that the current efficiency is as high as 100% and the deposition rate is fast, which is unmatched by other galvanizing processes. Because the coating crystallization is n
The problem of uneven thickness of anti-corrosion coating of The problem of uneven thickness of anti-corrosion coating of spiral pipe and its treatment methodSpiral pipes are mainly used as fluid pipes and piling pipes. After the steel pipe is made, if it is used for water drainage, it will generall
Crude oil prices have decreased. Various countries start to lockdown in response to the omicron variant. This way let people worry about the fuel supply. According to the reports of the COVID-19 vaccine against the new virus variant, this decreases people's worry about the fuel demand. And U.S. crud
