Inside the 8710-epoxy epoxy corrosion-resistant tube
details
Within the 8710-outer epoxy corrosion protection refers to the processing technology, the wall with 8710 paint, the surface of the use of epoxy resin anti-corrosion coating. Can effectively prevent or slow down in the transport and use of chemical or electrochemical reaction occurred in the phenomenon of corrosion of steel pipes. According to China's statistical data, the annual domestic steel pipe corrosion direct economic loss of more than 2,800 billion, the current global annual corrosion loss due to steel pipe up to 500 billion US dollars. Corrosion-resistant steel pipe can effectively prevent or slow down the corrosion of steel to extend the service life and reduce operating costs of steel.
The 8710-outer epoxy resin corrosion-resistant steel pipe according to the manufacturing process classification
(1) Seamless steel pipe manufacturing process can be divided into: hot rolling (extrusion), cold rolling (drawing), thermal expansion of the basic types of steel.
(2) welded pipe in accordance with the manufacturing process can be divided into: straight seam welded steel pipe, spiral welded steel pipe, coil butt welded steel pipe, welded pipe thermal expansion pipe.
Inside 8710 - outer epoxy resin anticorrosive pipe wall corrosion
The outer 8710-outer epoxy resin anticorrosive paint for the inner wall of the interpenetrating polymer network polymer, polymerization initiated at room temperature, the two networks can complement each other, resulting in synergies, coating non-toxic, high solids, low viscosity, is Corrosion resistance and water resistance, weatherability is very good new anti-corrosion coatings, and rust on the surface of steel is not demanding, the use of temperature can be -20 ~ 120 ℃ .
Inside the outer corrosion-resistant epoxy resin 8710 - corrosion
Outer 8710-outer epoxy anticorrosive outer anticorrosive coat Anticorrosion structure: the outer surface of the steel pipe wrapped with high density polyethylene material, with high mechanical strength and excellent corrosion resistance, can protect the steel pipe in the transportation, installation and use of the process In order to avoid the damage caused by external factors. Manufacture of outer tube should be added antioxidants, UV stabilizers and carbon black and so on. Polyethylene outer casing is easy to aging, such as open storage should be covered with tarp and other materials, stacking should be away from high heat and fire source, made of corrosion-resistant steel pipe, the prohibition of exposure, sudden cold, or polyethylene casing easy to crack, Performance and service life.
