Import Aluminum Alloy Pneumatic Cylinder Pipes — Buy in Bulk from Supplier in China

Aluminum alloy pneumatic cylinder pipes from Yingkou Zhenghe Aluminum Products Co., Ltd are drawn or extruded hollow tubes engineered to serve as barrel housings for reciprocating pneumatic actuators. The source material specifies lightweight construction combined with corrosion resistance and high tensile strength, though exact alloy designation, outer diameter, wall thickness, and length ranges are not stated in the listing data. These pipes must maintain precise internal bore tolerances to ensure proper seal engagement with piston rods and minimize air leakage at operating pressures typically between 0.4 and 1.0 MPa in industrial pneumatic systems.

The pipes are presumably supplied in common aluminum alloy grades such as 6061-T6 or 6063-T6, which offer typical tensile strength of 260-310 MPa and yield strength of 240-276 MPa, with Brinell hardness around 95 HB. Standard industry practice calls for internal surface roughness of Ra 0.4 to 0.8 micrometres to reduce friction and extend seal life. Anodizing to 10-25 micrometres thickness is typical for corrosion protection in humid or chemically exposed environments. The listing mentions various diameters and lengths are available, which in this product category usually spans outer diameters from 20 mm to 320 mm and wall thicknesses from 1.5 mm to 10 mm depending on bore size and pressure rating.

Primary buyers include manufacturers of automation equipment, automotive assembly systems, and material handling machinery where these pipes form the structural barrel of linear actuators, rodless cylinders, and pneumatic presses. Robotics integrators and OEMs of packaging and textile machinery also represent core demand segments. The supplier notes flexible MOQ options, though no specific minimum quantity, unit price, or standard lead time is provided in the source. Buyers should confirm alloy temper, dimensional tolerances per ISO 15552 or local equivalent, internal surface finish requirements, and whether cut-to-length or full-barrel supply is offered. Certificates such as ISO 9001 or material test reports should be requested to verify mechanical properties and chemical composition.

Yingkou Zhenghe Aluminum Products Co., Ltd is located at No.11 Hongsheng Street, Kelong Road, Xishi District, Yingkou, Liaoning Province, China, postal code 115004. The company holds an imported supplier tier and harbor trust tier classification. The response rate is listed as 0.00 percent with zero average response hours, which indicates either a new listing, inactive account, or data reporting gap that prospective buyers should verify directly before relying on inquiry channels. No information about establishment year, registered capital, production floor area, employee count, or annual turnover is present in the source material.

The listing presents the company as a source of aluminum alloy pneumatic cylinder pipes with properties including lightweight construction, corrosion resistance, and high tensile strength. The source description references ISO and SGS certifications, though no specific certificate numbers, scopes, or validity dates are provided, and buyers should request current documentation. The supplier claims to offer flexible MOQ options and competitive positioning for bulk supply orders. There is no stated specialisation beyond aluminum products, no named client references, no disclosed export markets, and no indication of in-house extrusion versus trading operations. Buyers are advised to confirm production capabilities, quality control protocols, and whether the supplier manufactures these pipes directly or sources them.
