Quality Control

1.During the smelting process, strict control is required both for the prescribed elements( 21 CrMo10), and for some harmful elements and gas, like P, S , Sn, As, Sb, Bi, and H, O, N.
2.To guarantee that the pipe moulds have reached our flaw detection standards, and that the forged blanks own refined grains, we have employed strict  forging technique upon the ductile iron pipe moulds.
3. After roughing process (drilling inner holes), a quenching and tempering treatment is given by vertical pit furnace upon the pipe moulds for further refined grains and higher comprehensive mechanical propertied.
4. CNC equipment is adopted for finishing for high processing precision.
5.All of the propertied of our pipe moulds are superior than the GB/T 25715 centrifugal ductile iron pipe mould standards.
