High Quality Concrete Pump Cylinder | ST52 Honed & Chrome Plated Delivery Cylinder for Pump Truck
Product Introduction
The concrete pump cylinder is one of the most critical components in a concrete pumping system, ensuring the stable and efficient delivery of concrete from the hopper to the pipeline. Manufactured from premium ST52 seamless steel tubes, this cylinder is precision honed and hard chrome plated to achieve an exceptional inner surface finish and wear resistance.
Each cylinder undergoes quenching and tempering heat treatment, which provides high strength and resistance against fatigue and corrosion. The chrome plating thickness of 20–30 μm guarantees smooth piston movement, reducing friction and extending service life under high-pressure conditions.
SPECIFICATION:
