Precision rolling pipe
Sanjack’s precision rolling pipe has extremely high precision and straightness can be less than 0.01mm/m.
The precision rolling pipe can beused for downhole pump barrel & plunger,
sucker rod coupling, ESP housing, motor bearing and housing. In 2015, Shengji
established precision rolling pipe production line. The quality and accuracy are
in the leading level in China. The annual production capacity reaches 4000 tons.
Shengji is GE, SCHLUMBERGER, DOVER excellent supplier.

1. Sucker Rod Pump
The precision rolling pipe is widely used in the manufacture of pump
barrel.In particular special materials such as brass, stainless steel, special
size (such as 120mm above) large diameter pump barrel, using finishing rolling
process to meet the standard requirements.
