Special and High Strength Sucker Rod

Special and High Strength Sucker Rod
Special and High Strength Sucker Rod (D Special, KD, HL, HY, KH, HS)

Description
Special and high strength sucker rods require higher mechanical properties. These special sucker rods enjoy strong corrosion resistance, and they are recommended for oil wells in complicated and bad environments.

Features
1. Higher mechanical properties.
2. Made of with special alloy steel.
3. Processed with special heat treatment work.

Advantages
1. Our special and high strength sucker rods are manufactured according to API Spec. 11B and based on industrial standards, special working environment and customer’s requirements.
2. These special sucker rods are made of with special alloy steel, and they are processed with special heat treatment. This effectively enhances the mechanical properties and extends the service life of sucker rods. It also assists in reducing the frequency of changing steel sucker rods, and therefore decreasing operating costs.
