30 CrMoA D grade API Sucker Rod 

Sucker Rod API grades

 1.Grade C sucker rod: It features moderate strength and good toughness and can be used in sour media environment, it is not susceptible to the sulfide stress cracking.

 2.Grade D sucker rod: It is made of quality alloy steel and heat treated, it features high tensile and yield strength, good toughness, it is applicable to non-corrosion or light corrosion environment.

 3.Grade V sucker rod: It features good resistance to corrosion, H2S, CO2 and NaCl media, and superior tensile strength. It is newly developed product and applicable to deep well pumping by small pump, forced production by large pump and production of thickened oil.

 4.Grade H sucker rod: It is the high strength sucker rod. The structure and the size of Grade H sucker rod are same as those of Grade D sucker rod, but the strength reaches 966-1,136Mpa(140,000-164,720psi) and it is applicable to deep wells and large displacement wells.

Sucker Rod Introduction:

The sucker rod is a steel rod that used to make up the mechanical assembly between the surface and downhole components of a rod pumping system.
The product conforms to API Specification 11B (Oil extraction rod Standard) and other related standard, authorized to use the API monogram.
All sizes of sucker rod (standard, heavy, polish rod) which conform to API specification latest version 11B are available in grade K, C, D and HL.

 Sucker Rod Technical Performances:
Adopting the advanced production line crack detecting, quenching, the continuous overall tempering and sand blasting processes to achieve higher mechanical strength ability with overall good performance.
The thread is cut by the special-purpose numerical control lathe which keeps the rod body still when cutting the threads. The special process could ensure the high precision of the thread with better reliability and life-span.
