Mud Pump Piston Rods

Dawopu pony rods (extension rods) and clamps are fabricated with premium quality, heat treat alloy steel with mirror- like surface polishing. The high standard of chrome finishing ensures excellent resistance against fatigue, abrasion and corrosion, offering longer service lifetime than the competitors.

Dura-Bar Grade 65-45-12 Ductile Iron

Original Material Hot Rolled 1018 Carbon Steel

Problems Solved Machining Cycle Time, Cost

Reduction, Weight Reduction

This manufacturer of hydraulic fracturing pumps had an initiative to find cost savings in the production of their pony rod.

A material which could replace the 1018 steel had to compare in performance, which included coatability. After testing

Dura-Bar, they found that the total coating time could be reduced by 25%, due to a shorter preheat cycle needed.

The manufacturer previously had a 30% scrap rate due to poor coating on the 1018 steel. Dura-Bar analyzed the coating

on our 65-45-12 and the lab results were favorable to the manufacturer.

Dura-Bar 65-45-12 also resulted in a 46% savings in machining cycle time and therefore a significant gain in machine

capacity.
