1.Pipe that shall be co-extruded from mould. In contrast to other techniques, it features excellent fluidity for hot-melt adhesive and higher adhesion strength with EVOH.

2.On line inspection for the increase of pressure: After pressure rises to 0.6-0.8 Mpa, EVOH tightly connects with plastic. Adhesion strength then has been improved.

3.Synchronization computer controller: In the whole production line adopts computer controlling, when production velocity changes, it only requires to input digits of production velocity, and other parameters by computer automatic controlled.

4.Optic inspection apparatus: Pipe wall quality and outer diameter for pipe controller. It features as higher temperature and pressure endurance, higher elasticity, lower creep resistance properties and without corrosion. Widely usage application: Cold and hot water cycling system, air conditional system, heating system.

1.Excellent lower temperature resistance, applicable temperature scope: -70℃～+95℃

2.Hardness and elasticity, higher inner pressure strength, (Nominal  stress:1.25MPa, burst pressure>4MPa, while 20℃.

3.In conformity with potable water hygienic standard, the pipe contains non-toxic components, not being rotten and breeding bacteria, it can be provided with the conveyance of potable water, purified water.

4.Higher chemical corrosion resistance and environmental stress cracking i.e. more kinds of chemical liquid can be conveyed.

5.Unprecedented advantages of pipe are being non-corrosive and non-incrustation, compared with common metal pipe.

6.With higher heat insulation and preservation properties, compared with metal pipe .

7.Having smoothness both inner and outer walls, the pipe have featured its smallest flow resistance. Attaining 30% of flow rate compared with zinc-plated steel pipe.
