Extension Rod

The Extension Rod is a key connecting component of the fluid end of the mud pump. It is mainly used to connect the piston rod and the crosshead, transmit power, compensate for installation gaps, and ensure the smoothness and continuity of the reciprocating movement of the mud pump. It is widely compatible with various mainstream mud pump models such as F series, 3NB series, and PZ series, and adapts to the use needs of different drilling scenarios.

This product is manufactured with high-quality materials and precision craftsmanship, featuring reliable quality and excellent performance. It is used in conjunction with the piston rod, and its specific characteristics are as follows:

1. High-Quality Material

Forged from 45# steel or 35CrMo alloy steel, the material has high strength, good toughness, excellent impact resistance and fatigue resistance, and can withstand high-pressure loads during drilling operations, providing a guarantee for the long-term stable operation of the product.

2. Precision Craftsmanship

The extension rod is treated with a professional heat treatment process, which effectively improves the hardness and wear resistance of the product, eliminates problems such as deformation and fracture during use, and extends the service life; at the same time, it adopts CNC precision machining with high dimensional accuracy and good interface matching, which can perfectly adapt to the installation requirements of various mud pumps.

3. Surface Treatment

According to requirements, the surface of the product can be galvanized, nickel-plated or decorative chrome-plated, effectively enhancing the corrosion resistance and wear resistance of the product, enabling it to adapt to the harsh environment during oilfield drilling (such as containing mud, chemicals, high temperature and high pressure, etc.), and further extending the service life of the product.

4. Complete Specifications

The core specifications are matched with the piston rod, including 1 5/8" and 1 1/2". At the same time, a full range of extension rods and supporting piston rods/pony rods are available, compatible with various mainstream mud pump models, perfectly interchangeable with original parts, easy to install, and no additional equipment modification is required.

The product has a stable structure and reliable connection. It has passed strict factory inspection and meets relevant industry standards. It can be widely used in various onshore and offshore drilling platforms, working together with the piston rod to ensure the continuous, stable and efficient operation of the mud pump system.
