The hydraulic cylinder pipe is mainly used in the cylinder part of the hydraulic system, which is an important part of converting hydraulic energy into mechanical energy. The hydraulic cylinder pipe converts hydraulic energy into mechanical energy through the working principle of the hydraulic system to achieve the movement of the object, such as pushing and pulling, lifting and rotating. Hydraulic cylinder pipe has the advantages of simple structure, reliable operation, large bearing capacity, etc. It is an indispensable part in modern machinery and equipment.





Produced using precision hot-rolled or cold-drawn processes, our seamless pipes undergo strict quality control during piercing, elongation, and sizing. Equipped with automated ultrasonic testing (UT) and eddy current inspection systems, we ensure consistent wall thickness (±10%) and superior internal/external surface quality.





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.
