The CNG tube trailer from Hangzhou Chengyingyi Energy Technology Co., Ltd. is a mobile high-pressure storage system designed for transporting compressed natural gas under pressures up to 250 bar. It consists of a modular frame with 12 to 18 seamless steel tubes, each with a nominal internal diameter of 168 mm and wall thicknesses between 12 mm and 16 mm, depending on the model. The trailer is mounted on a dual-axle chassis with air-brake systems compliant with ECE R13H standards.
The tubes are manufactured from 34CrMo4 or similar low-alloy steel, heat-treated for enhanced tensile strength and stress corrosion resistance. Each tube is hydrotested at 1.5 times its working pressure and marked with a permanent UIC code. The safety valve assembly includes dual relief valves rated for 275 bar, and the trailer is fitted with grounding straps and emergency shut-off valves. These features align with standard industry practices for CNG transport trailers in Asia and Europe.
This trailer is used by natural gas distributors, CNG refueling station operators, and industrial gas logistics providers requiring mobile storage for medium-distance transport. Buyers typically require compliance with ISO 11439 and DOT 4BA specifications. Packaging includes protective caps on tube ends and anti-corrosion coating on the chassis. Trade terms offered are FOB Hangzhou or CIF port of destination, with lead times of 60 to 75 days after deposit confirmation.

Before ordering, verify the trailer's compliance with your country’s pressure equipment regulations, such as PED in the EU or DOT 4BA in the US. Request copies of the hydrotest certificates for each tube, material test reports for the 34CrMo4 steel, and welding procedure qualifications. Do not accept generic declarations without documented evidence. Confirm that the trailer bears permanent markings for serial number, working pressure, and manufacturer ID as required by ISO 11439.
Lead time is typically 60 to 75 days from deposit, with FOB Hangzhou or CIF port of destination as the standard terms. Payment is usually 30% advance and 70% against shipping documents. Buyers must confirm the port of discharge, customs clearance responsibilities, and insurance coverage. The trailer is shipped disassembled in a 40ft container, so port crane capacity and import permits must be arranged in advance.
Conduct a pre-shipment inspection focusing on tube surface integrity, weld quality, valve function, and grounding continuity. Use ultrasonic thickness gauges to verify wall thickness at multiple points. Check that safety valves are sealed and calibrated. Request the manufacturer's final inspection report and ensure all documentation, including the Certificate of Conformity and Material Certificates, is provided in English. Retain samples of tube end caps and valve components for future reference.
