Import Cylinder Tube — Buy in Bulk from Supplier in China

The cylinder tube offered by Wuxi Petrotube Industries Co., Ltd. is a seamless steel pipe designed for hydraulic systems, providing structural support under high pressure. It is manufactured from premium carbon steel, with precise dimensional control to ensure compatibility with hydraulic cylinders in machinery. The tube is corrosion-resistant, extending service life in industrial environments.

Typical variants include cold-drawn seamless tubes with outer diameters ranging from 50 mm to 300 mm and wall thicknesses between 3 mm and 20 mm, depending on pressure requirements. Standard surface finishes for hydraulic tubes include honed interiors to reduce friction, while exterior coatings such as zinc or epoxy are applied for added protection. These tubes meet industry standards like ASTM A519 for seamless mechanical tubing, ensuring consistency in mechanical properties such as yield strength and elongation.

Common applications include hydraulic cylinders in construction equipment, forklifts, and manufacturing machinery. Buyers typically source these tubes in bulk for OEM assembly, with packaging options such as wooden crates or steel bundles to prevent damage during transit. The supplier confirms that the tubes are suited for high-pressure hydraulic systems, with typical working pressures up to 350 bar, depending on wall thickness and material grade.

Wuxi Petrotube Industries Co., Ltd. operates from Rm 5-1119, Zhongwei Int'l Mansion in Huishan District, Wuxi, Jiangsu, China. The supplier is classified as an imported tier with a harbor trust tier, indicating a baseline level of verification for international trade. The company specializes in hydraulic components, including cylinder tubes, and positions itself as a provider for industrial applications requiring precision engineering.

The supplier’s profile does not list a response rate or average response time, which suggests buyers should confirm availability and technical details directly. No additional information about certifications, production capacity, or client history is provided in the available data, so these specifics must be requested from the supplier.
