Protection, energy saving, corrosion resistance, long life and low cost.

1. Material composition:
(1) for the outer tube welding or seamless steel tube, inner lining for stainless steel pipe or plastic pipe.
(2) for stainless steel tube outer, inner lining for carbon steel tube.

2. Advantage: Composite pipe in water, gas, oil and natural gas to lose in the process of corrosion resistance, surface smooth, fluid resistance small, steel tube high mechanical strength, good sealing, overcoming the galvanization steel tube is easy to corrode, stainless steel tube high cost of the defect, is liquid transportation steel tube products.
