Good compatibility and easy mending
Double-layer epoxy inner and outer layers are both epoxy resin-based resin coating, the two are compatible with each other, patching using solvent-free epoxy coatings, good compatibility.Good cathodic protection
The double-layer epoxy coating has good compatibility with the cathodic protection and will not shield the cathodic prot.Good flexibility and resistance to bending
The coating material is made of epoxy resin with high molecular weight, which has good flexibility and excellent bendingScratch Resistance
The outer layer is modified epoxy coating with special scratch material, which has excellent scratch resistance.High Temperature Resistant
Double-layer epoxy anticorrosive steel pipe can withstand a maximum temperature of 110ºC.Connection Method
The flexible cap and insert coated plastic steel pipe is based on high-quality steel pipe, one end of the pipe is bevelled, one end is flaring, and then coated with plastic. The T-shaped rubber ring with the same structure as the spherical ink pipe is directly connected with the cap and insert. On the basis of retaining the advantages of coated steel pipe, it inherits the advantages of fast and reliable connection of ductile iron pipe flexible socket and socket, and complements the advantages of the two. And the two advantages complement each other.
