Hollow Sucker Rod
Our hollow sucker rod use the upsetting friction welding process at both ends, the internal surface use nano-titanium anti-corrosion coating or Ni-P platinganti-corrosion coating, after upsetting the welding area is twice of the normal hollow sucker rod, the anti-corrosion performance is excellent.
Hollow Sucker Rod is especially suitable for heavy oil wells, sand wells and wells which need continuous medium injection.
