Stainless honing tube for Hydraulic Cylinder

Stainless steel honed tube is processed by internal honing after seamless stainless steel tube blank forming. Different from carbon steel honed tube, it adopts stainless steel raw material including 304, 316L etc. Its inner bore is precision honed to form fine smooth surface with accurate dimensional tolerance.

Honing steel tube

High-precision seamless steel tubes with inner surface honed to achieve high smoothness, tight dimensional tolerance, and excellent straightness. Ideal for hydraulic cylinder barrels, ensuring stable operation, good sealing performance, and long service life.

Hydraulic Cylinder

A hydraulic cylinder is the core power execution component of hydraulic systems, which converts hydraulic pressure into linear mechanical force and linear motion. Our hydraulic cylinders are precision manufactured with high-strength seamless steel tubes, high-precision honing technology and imported sealing systems. With stable output force, low friction, no leakage and strong durability, our cylinders deliver consistent performance under continuous heavy-load and high-pressure working conditions.




Concrete Delivery Cylinder is the core component of concrete pump equipment, widely used for concrete pump trucks, stationary pumps, and boom pumps. As a key pressure-bearing part for concrete suction and delivery, it directly determines the pumping stability, construction efficiency and service life of the entire concrete pumping system.
Our concrete delivery cylinders are manufactured from high-quality alloy steel materials such as CK45 and ST52, featuring high strength, strong pressure resistance and excellent deformation resistance. The inner wall adopts professional hard chrome plating and precision grinding technology, achieving ultra-smooth surface, high hardness and superior wear resistance. This greatly reduces friction with concrete aggregate, effectively lowers seal loss, and extends the service life of the cylinder body and supporting piston seals.

Compatible Equipment:SANY, Zoomlion, XCMG, Putzmeister,Swching and other mainstream concrete pump models

Precision steel Pipes

Cold drawn seamless steel tube is manufactured from hot rolled seamless tube blank via multi-pass cold drawing, annealing and finishing processes. It features accurate outer & inner dimension, smooth surface and compact metal structure without welding seam. It can be further processed into honed tube, skiving & roller burnished tube for hydraulic cylinder usage.
