For the use of 3PE anticorrosive steel pipe many people also only know one or two, its role is really a wide coverage, it is suitable for underground coal mine drainage, underground grouting, positive and negative pressure ventilation, drainage gas, fire sprinkler and other pipe network. Heat and power plant process water waste residue, backwater pipeline. It is suitable for the water supply pipeline of spray prevention and sprinkler system. Electric power, communication, highway cable protection sleeve. It is suitable for high-rise building water supply, heat supply network, tap water engineering, gas transmission, buried water transmission and other pipelines.

Petroleum transportation pipeline, chemical pharmaceutical, printing and dyeing and other industries to transport corrosive medium process pipeline. Sewage treatment discharge pipe, sewage pipe and biological pond anticorrosion engineering. Agricultural irrigation pipes, deep well pipes, drainage pipes and other network uses, it can be said that 3PE anticorrosive steel pipes are essential in the current construction, and I believe that through the extension of science and technology, it will have more brilliant achievements in the future.

The main equipment for making 3PE anticorrosive steel pipe: buffer platform for steel pipe, pipe-shifting unit, tractor, pipe-penetrating machine, high-pressure blasting machine, repair platform, transmission line, preheating furnace for steel pipe, main inspection platform for shot blasting machine and return transmission line for different grid steel pipe, fast entry roller group, fast exit roller, inspection platform, etc. The production line for anticorrosive steel pipe can be used for single FBE, double FBE, double PE, double PP and 3PE anticorrosive steel pipe. The minimum processing diameter Φ104mm(4"), the maximum processing diameter is 1600mm(63"), the maximum processing capacity of more than 350m2/h, the production line includes steel pipe transmission system, surface treatment system, pipe dedusting system, steel pipe heating system, electrostatic spraying system, coating system, water cooling system, end cutting system, hydraulic and pneumatic system, Detection system and electric control system, etc.

Key words: 3PE anti-corrosion equipment; Anticorrosion insulation pipe equipment
