Coal Ss Pipe Anti Corrosion Steel Pipe With Surface Glass Cloth

Advantage
Anti-corrosion steel pipe is the three process of electrochemical degradation in buried pipeline, pipe anti-corrosion measures also from curbing a process into the hand, and if you give the outer wall of pipeline anticorrosion coating can increase the loop resistance, reduce erosion, current and dc power supply, make the steel pipe to soil forming negative potential, cathodic protection, can eliminate the anode potential, is fundamentally very process of Yin and Yang, anticorrosive coating table under the rule of law, cathode to maintain the rule of law , but once the anticorrosive coating damage, leakage of local iron will speed up the part, so the anti-corrosion coating and cathodic maintenance is severely, the method of combining economic and useful.

High density polyethylene coat anticorrosive structure:
Package of high-density polyethylene material outside the steel pipe surface, has high mechanical strength and good corrosion resistance, can protect the steel pipe in the process of transportation, installation and use to avoid the damage caused by external factors. Manufacturing outside casing should be adding antioxidants, ultraviolet stabilizer, carbon black and so on. Polyethylene outer casing is easy to aging, such as appropriate is used in open air tarpaulin cover, stacking area should be far away from the high heat and fire, made the anti-corrosion steel pipe, it is prohibited to insolate, quenching, or polyethylene outer casing is easy craze, affect the product performance and service life.

Commonly used for anti-corrosion steel pipe, vinyl, epoxy phenolic anticorrosive coatings, such as construction technology, generally require steel tube surface is nearly white level (Sa2.5). Verified by research institutions and the life of the coating depends on the quality of coating types, coating and construction environment factors, such as anti-corrosion of steel pipe surface treatment effect on the service life of coating accounts for about 50%, should be strictly in accordance with the coating specification requirement for anti-corrosion steel pipe surface error and summary, keep improving steel pipe surface treatment. Sampling test should be continuously mixed abrasive in the operation, according to the particle size distribution, to the derusting machine mixing into new abrasive, and mixing in a new abrasive, the number of steel shot to account for the main.

Application

About the use of anti-corrosion steel pipe top place, underground coal used in coal mine drainage, shotcrete, positive negative pressure ventilation, drainage, gas, such as fire sprinkler pipe network. Power plant, thermal power plant process water slag, backwater walks. Walked oil, oil pipelines, chemical pharmaceutical, printing and dyeing industries walks the process piping of corrosive medium. Sewage disposal, sewage discharge pipe, sewage pipe and biological pond anti-corrosion engineering. Agriculture, agriculture irrigation pipe, deep well pipe and drainage pipe network. Fire, about the sprinkler, sprinkler system water supply pipe has outstanding usability. Highway, electric power, communication, highway cable casing maintenance, etc. Municipal engineering, used in high-rise building water supply, heat supply network heating, water engineering, gas walks, buried water pipe, etc.
