If you are wondering how gas or propane cylinders are made, the ones we use in our kitchen or at work place you have come to the right video to learn exactly the same. In this video we go step by step in the process of how gas cylinders are manufactured and the different steps involved.

A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.The whole manufacturing process consists of the following steps:

1. Blanking & Body Forming
2. Valve Guard Ring & Foot Ring Production
3. Valve Neck (Valve Boss or Neck Ring) Production
4. Welding, Heat Treatment and Hydrostatic Testing
5. Surface Coating
6. Finishing Line with Pneumatic Testing
7. Valve Production

LPG Cylinder Production is composed of several sheet metal forming, surface treatment and testing processes. The process starts with blanking, deep drawing and piercing, trimming and joggling. Next are the welding operations for valve boss, valve guard ring, foot ring and the two halves. The finished cylinder is then heat treated, tested, shot blasted, painted and then the valve is attached and final tested.
