The appearance of the spiral steel pipe is not treated, which is beneficial to improve its service life.1. Use a wire brush, sandpaper, and other tools to polish the surface of the anticorrosive spiral pipe, which can remove loose oxide scale, rust, welding slag, etc.2. Use solvents and emulsions to
1. Longer life, ordinary steel pipes have a certain lifespan. When ordinary materials are treated with anticorrosion, their lifespan can be as long as 20-30 years or longer. It can be described as the "lifetime star" in the pipeline, and it can be saved in use. It saves replacement, maintenance and
316L stainless steel pipe is a kind of pipe widely used in construction engineering. The shape of the tube is an oblong hollow steel tube. Mechanical equipment, petrochemical equipment, medical equipment, food, and light industry pipelines or mechanical parts will all use 316L stainless steel pipes.
The main purposeGalvanized pipes are usually used to loosen gas and heating. Galvanized pipes are also used as water pipes. However, after a few years of use, a large amount of rust will be generated. The yellow water that flows out will not only contaminate sanitary ware but also breed bacteria on
It is recommended to use polyethylene anti-corrosion adhesive tape with a special primer for external anti-corrosion of the pipeline. This anti-corrosion process does not require high requirements on the construction site and is pollution-free. It can be prefabricated for corrosion protection, and t
The API standard stipulates that the internal and external surfaces of import and export petroleum casings shall not have folds, separations, cracks, and scars. These defects should be completely removed, and the removal depth should not be less than 12.5% of the nominal wall thickness. Petroleum ca
1. Manufacturing and processing methods of seamless steel pipes:(1) Hot rolling (extruded seamless steel tube): round tube billet→heating and piercing→three-roll cross-rolling, continuous rolling or extrusion and one-off tube→sizing (or reducing)→cooling→straightening→hydraulic pressure Test (or fla
The wall thickness can be called thick-walled steel pipe. There are some doubts about this. It depends on the ratio of the outer diameter of the steel pipe to the wall thickness of the steel pipe. For example, a steel pipe with a diameter of 50 mm, 10 mm can be regarded as a thick-walled steel pipe.
Stainless steel pipes are explosion-proof. The pressure-bearing and explosion-proof ability of stainless steel pipes depend on the wall thickness of the pipe. If thick-walled stainless steel pipes are used, it is no problem to withstand pressures of 10Mpa (about 100 kg) or even higher. Threeway Stee
The stainless steel flange is not completely rust-proof, but its oxidation resistance is stronger than that of ordinary steel, so it is called stainless steel.Stainless steel not only can resist atmospheric oxidation, but also can corrode in acid, alkali, and salt media. However, the size of its cor
