All modules are made from internally hardened AISI 8620 or 4135 alloy steels with precise machining,complex heat treatment,and strict inspection in order to provide extremely durable modules for high-demand pumping requirements in current oil and gas industry.
After the blank is forged and heat-treatment,damage or crack detection &static water pressure test will be car- ried so as to be sure to reach to the requirement of stipulated pressure.
Inner cavity of the module is machined by digital control lathe,which is guaranteed no different of the dimension in each section of the part.
The special processing technologymanufactureradopted -Taper surface rolling &press Technology-make its ex- ternal taper connecting surface reach to 100%.There is no crevice for mud to go inside the cavity so as to extend its service life.
