50kg Gas Cylinder Making Machine Semi Automatic Oxygen Cylinder Making Machine

150KW LPG Cylinder Production Line Gas Cylinder Making Machine

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.

We produce and supply complete LPG cylinder production line for the manufacturing of different types of LPG cylinders. The production capacity of LPG Cylinder Production Line can be different according to the customer requirement. The usual speed of the line starts from 50 cylinder per hour and goes up to 300 cylinders per hour capacity.

Specifications

1. LPG Cylinder Body Production Line
The blanks are cut by the hydraulic press & blanking tool set or by the rotary shear from the steel coil to required dimensions automatically. The blanks are loaded manually / automatically to specific hydraulic deep drawing press to be formed as upper and lower halves of LPG cylinders. Then deep drawn parts are trimmed and joggled on trimming and joggling machine before welding to have matching upper and lower pieces when assembled together.
Process:
Blanking with hydraulic press and blanking die set
Deep drawing hydraulic press with tool sets
Trimming and joggling machine

2. LPG Cylinder Foot Ring and Guard Ring Production Line
Various types and sizes of guard ring and foot rings can be produced in flexible production line. The line consists of
decoiler-straightener-feeder, blanking & forming & stamping presses and related tool sets, round bending machines, serial number punching unit, welding machines which are designed and produced by “KELAI”.

3. LPG Cylinder Body Welding Line
The guard rings and foot rings are welded onto upper and lower cylinder halves by automatic welding machines. The valve boss (neckring) is welded onto the upper cylinder half and then the upper and lower halves are welded together by automatic circumferential welding machines. For three pieces LPG cylinders are welded by specific automatic longitudinal and circumferential welding machines. All welding machines are equipped with well-known welding rectifiers to achieve uncompromising welding quality.
