Our company produces high-precision seamless honed tubes using premium alloy structural steel, manufactured through multi-pass cold rolling and precision honing processes. The products feature low inner surface roughness, high dimensional accuracy, and excellent straightness, making them suitable for high-pressure hydraulic systems that demand strict requirements for motion precision and sealing performance.

This production line features an integrated cold rolling-honing manufacturing system. Using our proprietary high-quality alloy steel tube blanks as the base material, we optimize material properties through precision cold rolling and controlled heat treatment processes. The core honing stage is equipped with CNC-specific equipment and a constant-temperature control system, ensuring high-precision inner diameter dimensions and stable surface quality. The entire line incorporates automated inspection points to achieve full-process quality traceability. With its scalable production capacity, this production line can meet customized requirements for high-performance hydraulic cylinder tubes across various industries.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
