Import 700bar Hydrogen Cylinder For Vehicle/Bus/Car — Buy in Bulk from Supplier in China

Shanghai Salan Industry And Trade Co., Ltd. manufactures Type III and Type IV high-pressure hydrogen cylinders rated for 700 bar (70 MPa) service pressure, targeting on-board vehicle storage for fuel cell buses, passenger cars, and commercial transport applications. The Type III construction uses an aluminum alloy liner with full carbon fiber composite overwrap, while Type IV employs a non-metallic liner with carbon fiber reinforcement. Both designs conform to typical standards for 70 MPa hydrogen storage in automotive applications,为多, including ISO 11119-2 and UN R134 for Type III, and ISO 11119-3 or SAE J2579 for Type IV configurations. Nominal water capacity ranges from typical 140 litres for passenger vehicle configurations to larger formats for bus and heavy-duty applications, with actual dimensions varying by vehicle integration requirements.

The aluminum alloy liner in Type III cylinders uses typical 6061-T6 or comparable aerospace-grade alloy with standard thickness calculated to withstand cyclic pressurisation. Carbon fiber overwrap utilises T700 or T800 standard modulus fibres in epoxy matrix, with helical and hoop winding patterns optimised for pressure containment and fatigue resistance. The 700 bar operating pressure represents the standard automotive storage target, balancing volumetric energy density against cylinder weight. Hydrogen permeation through the liner, burst ratio (typically 2.25 to 2.35 times service pressure for composite cylinders), and cycle life (standard 15,000 cycles for automotive applications) are critical performance parameters. The supplier's facility in Fengxian District, Shanghai, covers 68,000 square metres with stated front-line production staff.

Primary buyers include fuel cell vehicle OEMs, hydrogen refuelling station operators, fleet conversion specialists for bus and commercial vehicle applications, and aftermarket retrofitters. Type III cylinders dominate current bus deployments due to proven track record, while Type IV offers weight savings for range-sensitive passenger vehicles. Buyers must confirm with Shanghai Salan whether specific cylinders carry UN R134, ISO 19881, or EC79/2009 type approval for target markets, as regulatory acceptance varies by jurisdiction. The supplier mentions annual capacity of 1.2 million pieces across all pressure vessel categories, though hydrogen-specific cylinder allocation is unstated. Packaging, handling procedures for high-pressure gas equipment, and regional installation certification requirements should be discussed directly with the supplier.

Shanghai Salan Industry And Trade Co., Ltd. is located at No. 6997 Daye Road, Jinhui Town, Fengxian District, Shanghai, China, postal code 201317. The company holds harbour trust tier classification with a zero percent response rate and zero recorded average response hours. The registered capital is stated as 51.8 million RMB. The facility encompasses 68,000 square metres with 100 front-line workers, 12 technologists, and 6 quality inspectors according to the supplier's own description. The business scope covers manufacturing and sales of B1 and B3 grade pressure vessels, technology development, transfer, and technical consultation services.

The supplier's profile indicates specialisation in multiple pressure vessel categories including LPG tanks, LNG tanks, CNG tanks, aluminium alloy seamless cylinders, and both Type III and IV hydrogen cylinders for vehicle applications. The company claims designation by the Ministry of Labour for LPG steel cylinder manufacturing. However, no specific ISO 9001, IATF 16949, or pressure equipment directive certification details are provided in the available data. Buyers should independently verify current quality management system certifications, specific hydrogen cylinder type approvals, and actual production allocation between hydrogen and other pressure vessel lines. The stated annual capacity of 1.2 million pieces appears to aggregate all product categories rather than hydrogen-specific output.
