Technical Key Points

Ø In order to guarantee the required pressure of typical pump casting, when making the technical scheme in casting process, we must ensure the necessary riser pressure and effect of the casting,and control the technological yield of the casting between 50%-55%.

Ø In order to ensure the filling capacity of molten steel, to increase the height of the main risers to improve the riser pressure is particularly important, which is easy to be ignored.

Technology Advantages

Ø We will develop new materials when necessary.

Ø Our advantage lies in component control, especially for ultra low carbon steels, stainless steels and duplex stainless steels.

Ø All our technology innovation only for one aim--- the best quality, even that means a higher cost and lower production rate.

Ø Crack is the fatal defect of pressure vessel. We guarantee that the pump and valve castings have no crack inside and outside, and have good withstand voltage performance.
