The CNG cylinder from Hangzhou Chengyingyi Energy Technology Co., Ltd. is a composite pressure vessel engineered for storage of compressed natural gas at up to 250 bar. It features a polymer liner reinforced with carbon fiber, optimized for weight reduction while maintaining structural integrity under high pressure. The design complies with ISO 11439 and meets the safety requirements for automotive and industrial CNG applications. Dimensions and capacity are tailored for retrofitting vehicles and stationary fuel systems.
The cylinder uses a Type IV composite construction, which is standard for lightweight CNG storage in transportation. The inner liner is typically made of high-density polyethylene, and the outer wrap consists of carbon fiber epoxy resin. These materials provide corrosion resistance and fatigue endurance beyond steel alternatives. The wall thickness and burst pressure margin are engineered to exceed regulatory minimums, though exact tolerances are not disclosed in the listing.
This cylinder is primarily purchased by fleet operators, public transit agencies, and industrial gas distributors in Asia and the Middle East. Buyers typically require units in batches of 50 or more for vehicle conversions or refueling station installations. Packaging is bulk-loaded in wooden crates, and delivery terms are FOB Hangzhou Port. Lead time and minimum order quantities are not specified and must be confirmed directly with the supplier.

Before ordering, verify the cylinder's compliance with ISO 11439 and request a copy of the Type IV certification from the manufacturer. Confirm that each unit has a permanent serial number, manufacturing date, and working pressure marking. Ensure the supplier provides a test certificate for hydrostatic pressure and burst margin, as these are non-negotiable for safety and import clearance.
Logistics are typically FOB Hangzhou Port, with delivery by sea in wooden crates. Lead time is not stated and may exceed 45 days for bulk orders. Buyers must confirm Incoterms, container loading method, and whether the supplier handles export documentation. Payment terms are likely T/T in advance or L/C, but this must be negotiated directly.
On arrival, inspect for surface damage, verify labeling matches the test certificate, and check for signs of delamination or coating cracking. Request a sample cylinder for destructive testing if importing for commercial fleet use. Retain the certificate of conformity and test reports for customs and regulatory compliance. Documentation must include material traceability and pressure test records.
