WHAT IS CYLINDER TUBE

The cylinder pipe is used for the manufacture or repair of hydraulic cylinders, but it is not processed for the inner diameter, also known as the honing cylinder pipe or polishing pipe. Honing tubes are produced from our CDS tubes (cold-drawn seamless steel pipes) or DOM tubes (core-drawn steel pipes), and the finishing of the inner diameter is achieved by internal diameter honing or SRB(peeling and roller polishing) machining. The honed pipe has a fine inside diameter tolerance and a high surface finish.

As a leading manufacturer in China, we can produce cylinder tubes of various sizes and lengths. Honing tube is the most important part of hydraulic cylinder, the quality of honing tube directly affects the final quality of hydraulic cylinder, safe and reliable. All of our production activities comply with ISO9001 and all quality standards and policies. We ensure that every honing tube from raw material to finished cylinder tube is strictly produced according to the standard and fully controlled manufacturing.
