Introduction.

Chengli factory manufactures this 25tons LPG semi trailer for bulk liquid gas transport. The unit carries a 49.6cbm cylindrical tank built from heat treated Q345 steel. Three BPW axles distribute weight across the road. Each axle carries 12R22.5 tubeless tires for stable highway running. The JOST landing leg supports the trailer when detached from the tractor. Operators fill and unload the tank through a DN450 manway on the upper dome. Emergency shut-off valves sit above the tank for rapid isolation during incidents.

Key Features.

The trailer includes several safety and monitoring components positioned for quick operator access. A liquid level gauge shows fill volume without opening the tank. A pressure gauge and pressure indicating thermometer display internal conditions during loading and transit. Ball valves control outlet flow to delivery hoses. The Q345 steel body receives protective surface treatment before final assembly. Every weld undergoes 100 percent flaw detection before the trailer leaves the factory floor.

Performance and Configuration.

Crews connect the trailer using the fifth wheel coupling and secure air and electrical lines. The landing leg lowers the front end for stable parking during paperwork and inspection. Operators open the manway to check internal cleanliness before each fill cycle. The liquid gauge confirms target volume during loading. Valve sequences follow plant standard operating procedures to prevent overpressure. After unloading, hoses drain and capping plugs secure all openings.

Maintenance and Inspection.

Drivers perform daily walk-around checks covering tire condition, valve seals, and gauge visibility. Scheduled service includes brake inspection, axle bearing review, and suspension component verification. Monthly procedures focus on pressure relief devices, emergency cut-off valve operation tests, and instrument calibration. Wear parts such as valve seals and hose gaskets replace per manufacturer guidance. Weld zones on the tank body receive visual examination during routine inspections.

Applications.

This trailer serves municipal fuel distributors moving LPG to retail stations and industrial plants. Fleet operators run it on regional delivery routes covering urban and rural corridors. Construction sites and remote camps use it for propane supply during off-grid power generation. The design fits standard highway and provincial road conditions across varying climates. Buyers with established LPG distribution networks value its proven configuration and direct factory pricing from Chengli.
