Sucker Rod

Brief 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.

Technical Performances

1、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.
2、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.
