Our company now has fixed assets of 42000,000 yuan,covers an area of about 18,000 square meters with modern standard factory buildings over 8500 square meters. We have machining equipment over 100 units, which is used to produce valve gate and seat; Besides, there has 3 sets of America Praxair supersonic flame spraying equipment(JP8000);And WC-C010Cr4 alloy powder---used to spray the surface, can increase product hardness (HV≧1300), improve the abrasion-resistant and corrosion-resistant on the surface. It is the best technique of petroleum machinery products.At the same time, oxygen production line is mainly for the oxygen supply of supersonic spraying equipment, it is the only one factory which both has oxygen production line and supersonic spraying production line,the purity of oxygen is more than 99.6,and has two oxygen tank of 100 cubic meters which is only use to supply oxygen for supersonic spraying,in order to ensure the quality of supersonic spraying product.
