How Gas Cylinders Are Made? (Mega Factories Video)
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.

The welding part looks very interesting. Always liked metal work although I became an electrician
I am job

This factory looks absolutely brand new, and the "workers" are moving rather stiffly. It seriously looks like a bunch of engineers are perfecting the processes and settings prior to handing it over to the owner and workers.
That is because Repkon does not make cylinders. They build plants that make cylinders.
My God! What an observation?
We in the Netherlands still useing propane and butane cilinders produced in the 1950's these are just made as well. Verry nice modern factory.
The jigsaw puzzles which we all solved right from our childhood days are manufactured with some great engineering behind them. Watch this exciting and informative video to learn more! Watch here: kzhead.info/sun/od2lddCreWuDnn0/bejne.html
I liked the Submerged Arc welding processes.Its been brilliant for 70 yrs. now.Remember it was in vogue wnen i served my Engineering Apprenticeship in the 1950`s/ 60`s when we made very big pipes and pressure vessels too.
Very interesting video. I liked all the steps, but the furnace to release welding stresses was an interesting surprise. thanks for posting! :D
Couldn't agree more!
It was interesting to watch how they melted, and welded the calinger back together.
I liked the welding process in the assembly, this industrie is very very safe.
No ear protection for workers. Factory looks top notch.
Blanking at the beginning is really deep drawing of a deep drawing grade of metal.
I have not wondered how cylinders are made until now. 😂
4.42 wouldn't it be an idea to only have the welding start after the door is shut ? All you need is a switch on the door, like a chuck guard on a lathe. Interesting vid all the same, no swarf or fillings were made throughout the whole process
There's no filling until the cylinder is finished and tested. There are, however, filings when metal is drilled or machined.
I thought the same thing, a simple switch on the door jamb would do. An audio or visual indicator, both would be ideal, can alert the worker that the welding is done.
Liked the welding!👍☘️
This is what I was looking for! Thanks.
Hey all of those welding processes are really amaizing
Very very
All processes was good
I’m watching your videos and I like them but I would also like to know where the factory was located.
Balibey, Fabrika Sk. No:1, 34980 Şile/İstanbul, Turkey
Stress Releveing was best
This should be in plant in lran or gulf ?
