Galvanized pipe for water

Galvanized pipe for water belongs to the seam welded steel pipe.

Galvanized pipe for water

Welded steel pipe refers to the steel belt or steel plate bending deformation shapes such as round, square and then welded and jointed on the surface of steel pipe. Welded steel pipe is made of billet is steel plate or strip.

Bought from the market pipes, both ends will be color-coded, which means that water uses. Water pipes on blue, red spray hot water pipes, water pipes under the inkjet green, gas pipes and gas meter spray satin, heating pipes whitewashed.

Which galvanized water pipe when the pipe has been banned, because the traditional galvanized pipe rust, corrosive, easy to scale, easy to breed microorganisms produce secondary pollution, the use of a few years, a large amount of rust inside the tube, out of the yellow water not only pollute the ware, and mixed with non-smooth inner wall of the breeding of bacteria, corrosion caused by high levels of heavy metals in water, serious harm to human health.

FAQs

Advantage of ERW pipe

The alloy content of the coil is often lower than similar grades of steel plate, improving the weldability of the spiral welded pipe. Due to the rolling direction of spiral welded pipe coil is not perpendicular to the pipe axis direction, the crack resistance of the spiral welded pipe materials.
