Description:
The sucker rod, an essential part in the rod production system, is used to connect the pumping unit on the ground and the oil well pump down in the well.Products comply with Specifications of Sucker Rods (API Spec 11B) and other related standards, and have acquired the authorization to use Official API Monogram.The company produces K, C, D or HL sucker rods with various specifications complying API's requirements.
Technical Performance & Characteristics:
1. Advanced online fault detection, hardening, continuous overall tempering and ball blast techniques are incorporated so that mechanical strength and overall performance are enhanced.
2. Threads are processed on special numeral control lathes avoiding any rotation of the rod and then subject to roll forming so as to ensure high precision, reliable performance and extended service life.
