In modern household water supply pipes, the corrosion resistance of water pipes is very important, because it means we can drink healthy and pollution-free drinking water. When PPR plastic pipes were promoted as tap water pipes, a test report from the Shanghai Disease Research Institute showed that

Usually, we use epoxy coal tar pitch paint, if the requirements are high, you can use 3 oils and 2 cloths. 3 layers of paint and 2 layers of the glass fiber cloth, staggered construction. If required, the primer and topcoat of epoxy coal tar pitch are generally used directly, and each is applied twi

Galvanized steel pipes are made of steel that has been covered with a layer of zinc metal. During the galvanizing process, we immerse the steel in a molten zinc bath, ensuring a tough, uniform barrier coating.Product name: galvanized seamless steel pipeSize: 219*5.5*12/273*6.0*12Application: Industr

1. The premise must be polishedThe galvanized layer at the weld must be polished off, otherwise, bubbles, trachoma, false welding, etc. will occur. It will also make the weld brittle and reduce rigidity.2. The welding characteristics of galvanized steelGalvanized steel is generally coated with a lay

Straight seam steel pipes are welded by a welding method parallel to the longitudinal direction of the steel pipes and are widely used. With the same diameter and length, the welding length of the straight seam steel pipe is much less, while the welding length of the spiral steel pipe may increase b

The hollow steel section comprises various material welded structural hollow sections for multiple purposes. No matter whether it is building construction, spare parts manufacturing, or even working parts construction. It is also used in these projects.Product name: square steel pipeSize: 400x200x9.

Steel bending pipe processing and forming process1. Die forging. For socket welding and threaded tees, crosses, elbows, and other small pipe fittings, the shapes are more complicated and should be manufactured by the die forging process, and the die forging blanks should be rolled profiles, such as

Spiral steel pipes are mainly used as fluid pipes and piling pipes. If the steel pipes are used for running water after they are made, they will generally be treated with anti-corrosion treatment on the inner or outer surfaces. The general anti-corrosion methods include 3pe anti-corrosion, epoxy coa

There are significant differences between straight seam steel pipes and steel pipes. I believe that many people must think that the two are similar in terms of usage and performance. Straight seam steel pipes are higher than steel pipes. The better types sold in the market are electric welded steel

The main process parameters of high-frequency straight seam welded pipe include welding heat input, welding pressure, welding speed, opening angle, position and size of the induction coil, position of impedance, etc. These parameters have a greater impact on improving the quality of high-frequency w
