The high-pressure water jet-sand blasting dephosphorization system, especially for small diameter bimetal composite pipe, which is researched and designed by Guangzhou Advance-Tech Co., Ltd specialized for Hebei Xinxing Ductile Iron Pipes Co., Ltd., has successfully finished the treatment of first lot of bimetal composite pipe, around 10 tons, in Dec.2011.

Bimetal composite pipe could change the thickness of basic layer and coating layer, so it could be used in many industries to transport fluid, gas, powdered coal, deslagging and oil. It also could be used as the extra high pressure/corrosion/ temperature resistance pipeline, which is a good solution to the key problem of state energy.

The newest high-pressure water jet-sand blasting dephosphorization system, researched and designed by Guangzhou Advance-Tech Co., Ltd., owning advanced, mature and stable technology, designed with small sprayer/high pressure/ automatic sand blasting, could remove the oxidation layer/rust/oil of the surface of steel pipe/wire/mechanical components effectively, to make the surface smooth and refined. The processing effect of the first lot of bimetal composite pipe could meet the special high-tech requirements. It could make the pipe inner surface no oxidation layer, no rust under different conditions, while keep the pipe surface nearly without any damage. This environmental treatment technology plays a very important role in environment protection and pollution reduction. It reflects the spirit of Advance-tech again -- Create New Value to Pipe Industry, Contribute to Society and Environment with persistent innovation of advanced composite pipe technology.
