Factory Wholesale Price Carbon Steel Pipe Square Hollow Section Galvanized Shs Steel Pipe

Short Description:

Galvanized square pipe is electric galvanized, galvanized amount is very small, only 10-50g/m2, its own corrosion resistance is much different than hot galvanized pipe. Regular galvanized pipe manufacturers, in order to ensure quality, most do not use electric galvanizing (cold plating). Only those small enterprises with obsolete equipment use electric galvanizing, of course, their prices are relatively cheap. The Ministry of Construction has formally announced the elimination of cold galvanized pipes with backward technology, and it is not allowed to use cold galvanized pipes as water and gas pipes. The galvanized layer of cold galvanized steel pipe is an electric coating, and the zinc layer is independently layered with the steel pipe matrix. The zinc layer is thin, and the zinc layer is simply attached to the steel tube matrix and easy to fall off. Therefore, its corrosion resistance is poor. In new residential buildings, it is prohibited to use cold galvanized steel pipes as water supply pipes.

Product Detail

Galvanized square pipe is a kind of hollow square cross section steel pipe with square section shape and size made of hot rolled or cold rolled galvanized strip steel or galvanized coil as blank through cold bending processing and then through high frequency welding, or the cold formed hollow steel pipe made in advance and then through hot dip galvanized square pipe

Main Application

Features

Galvanized steel pipe is a welded steel pipe with a hot dip plating or electric galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and extend the service life. Galvanized pipe has a wide range of uses, in addition to the pipeline pipe for water, gas, oil and other general low pressure fluids, it is also used as the oil well pipe, oil pipeline, especially in the oil field of the petroleum industry, the oil heater, the condensing cooler of the chemical coking equipment, the tube for the coal distillation and washing oil exchanger, and the pipe for the trestle pipe pile and the support frame of the mine tunnel.

3. Reflectivity: It has high reflectivity, making it a barrier against heat

4, the coating toughness is strong, galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage in transport and use.

Application

Application

Often said galvanized pipe, the use of galvanized pipe gas, heating with the kind of iron pipe is also galvanized pipe, galvanized pipe as a water pipe, after several years of use, the pipe produces a large number of rust scale, the outflow of yellow water not only pollution sanitary ware, but also mixed with not smooth inner wall of the bacteria, corrosion caused by the water heavy metal content is too high, seriously harmful to human health.
