LPG Cylinder Production Line

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.


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.

Product Description

 

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.

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".

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.

LPG Cylinder Heat Treatment and Hydrostatic Testing Line

All welded LPG cylinders will be heat treated for normalizing after deep drawing and welding process. The cylinders pass through the high-tech oven from entry to exit side on the conveying system for the proper heat treatment process with preheating, heating and cooling steps. All cylinders are heated up to 930ºC and are kept that temperature for a curtain time.
All cylinders which are cooled gradually after heat treatment process will be hydrostatically tested under 34 bars to visual check of the forming and welding defects. If requested, full automatic in-line hydrostatic test unit can be used for reducing handling and increasing productivity.

LPG Cylinder Shot Blasting & Metallization & Painting Line

All LPG cylinders will be shot blasted to remove all rust after heat treatment and to prepare surface for
metallization and painting. After that all LPG cylinders conveyed on the overhead conveyor are zinc coated by automatic arc spray metallization guns & painted automatically by electrostatic powder painting method by the spray guns and cured in the tunnel type modern paint curing oven. If requested, the second color wet painting can be applied on the same line.
By using high-tech manipulators which are developed and produced by us, cylinders can be loaded & unloaded to shot blasting machine and painting line overhead conveyor automatically.
