Process Flow
Old LPG Cylinder Recovery Line: Residual Recovery, Inner Cleaning, Valve Dismantling
There’s residual gas and liquid inside the old cylinders. It will cause explosion if it’s not vacuumed before valve taken off. So to assure the plant safety, the first step is to recover the residual gas and liquid inside the cylinder. And then the valves can be taken off. After the final cleaning of the gas and rust inside, the cylinders can be reconditioned.

LPG Cylinder Reconditioning Line
The compatible Reconditioning line can refurbish various types and sizes of the used LPG cooking gas cylinders. The Reconditioning line is designed and produced by “THLPG”. It mainly consists Steam Cleaning Machine, LPG Cylinder Normalizing Furnace, Shot Blasting Machine, Hydrostatic Testing Machine, Air Leakage Testing Machine and other supplementary machines.
Unlike the brand new cylinder heat treatment, the reconditioning temperature only needs 500~600 degrees Celsius. Its main aim is to burn the old paints and rusts outside the cylinder. And to save time and steel grits on the shot blasting process.

LPG Cylinder Hydrostatic Testing Line
After the heat treatment process, all cylinders are gradually cooled and then hydrostatically tested at 34 bar pressure to visually check for forming and welding defects. On request, we can provide a fully automatic in-line hydrostatic testing machine to reduce your workload and increase your Reconditioning efficiency.

Net weight weighing, inline printing, valve thread cleaning, valve tightening, leak testing, vacuuming, laser marking, QR code installation and other processes are all automatically completed on the online finishing and leak testing line.
Single-color logos and labels are printed by screen printers, and multi-color logos are printed by automatic pad printers. Currently, many countries require QR codes to be attached to cylinders for subsequent safety management and traceability. China’s GB standard requires welding on the cylinder guard ring, and some countries allow rivets to be riveted on the guard ring.
