THREE LAYER ANTICORROSION PIPE
Anti corrosion layers
1.3PE anti corrosion layers: adhesive-epoxy(60-80µm),copolymer adhesive(170-250µm) and high density polyethylene(about 2mm);
2. 2PE anti corrosion layers: copolymer adhesive (170-250µm) and high density polyethylene (about 2mm)
3.Peel strength: 3PE layers is more than 100N/cm, 2PE layers is more than 70N/cm
4.Spark leak level; ≥25KV
5.impulse withstand test: ≥50kg/cm
Remark: we can use coal tar epoxy as the anti corrosion layer according to customer’s request.
Inner Steel:
Material: 20# and Q235 seamless steel tube or spiral steel tube.
Surface treatment: blasting (the standard can be GB/T9823-1988, Sa2.5)
Surface anchor pattern of the steel tube: 40—100μm (increase the surface area of the steel tube, also Improve steel adhesion)
Widely used on urban water network, chemical petroleum and natural gas, and other industrial material liquid and gas pipeline system
Applicable temperature: less than 70°C
