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)

Peel strength: 3PE layers is more than 100N/cm, 2PE layers is more than 70N/cm

Spark leak level; ≥25KV

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)
