Ø We are willing to develop all new material only if it’s required in application.
Ø Advantage technology in composition control, especially super low carton steel, stainless steel and duplex stainless steel.
Ø Crack is fatal flaw for pressure resistant container. We can make sure no crack inside and outside of the pump and valve castings, and a good pressure-resistant performance.
Ø All our technology innovation only for one aim--- the best quality, even that means a higher cost and lower production rate.
