LPG cylinders Quality Standard
||DOT 4BA 240
||DOT 4BW 240
We are capable to manufactured cylinder by maintaining any standard cause of our main vision to export cylinders abroad and mitigate customer’s requirement.
Raw Materials of Standard Quality
JMI LPG cylinder maintain highest quality raw materials imported from Turkey,
Japan and Korea are using in the production of JMI LP Gas cylinders
to mitigate all the LPG safety aspects besides to eliminate all the
Raw Materials Specification
• Cylinders Body
JIS G 3116 SG 295 or Equivalent
• Guard Ring and Foot Ring
DIN EN 10025-2 S235JR or Equivalent
WELDING, HEAT TREATMENT & HYDROSTATIC TESTING LINE
The submerged arc welding technique is applied on the welding of body
halves on the seam welding machine and generally on the welding of the
valve boss to the upper cylinder half. The welding automats with reliable
welding power packs and control units are utilized to achieve the
uncompromising weld quality with degree of automation needed for the
required production capacity per customer. The MIG/MAG welding technique
is applied for the welding of foot rings and valve guard rings with the
body halves. In order to relieve all the stresses caused by forming and
The cylinders are passed through a heat treatment furnace where they
are heated up to 930e c degrees of temperature for certain time before
getting cooled gradually.
The hydrostatic testing of the heat treated LPG cylinders can be done
on automated carousel type machines or on fixed station type machines
to increase the internal pressure up to 35 bars for visual inspection
as per requirements of the cylinder design specifications.
SURFACE COATING & FINISHING LINE
The LPG cylinder surfaces are shot blasted by the shot blasting machine
in order to clean up the scales caused by the heat treatment operation
to prepare the surface for the painting and / or zinc spraying.
The double layer oven cured painting of the cylinders is achieved
automatically by the robotic paint application system in the painting
line as the cylinders are conveyed on an overhead conveyor system through
the primary and final coat painting cabinets separated by flash off
tunnels before they get cured in the canopy type modern paint curing
oven. After the tare weighing and marking of the cylinders, the valves
are attached by automatic torque controlled screwing machines and tested
against any leakage at the valve region by the pneumatic leakage testing
machine of the finishing line. One of the batch type quality control
equipment called by the international standards is the burst expansion
testing unit where the volumetric expansion ratio and the burst pressure
is measured to the full satisfaction of even most stringent requirements.
Cylinders are put through a series of test to conduct a series of physical and chemical qualities, tensile,
Burst and X-ray tests at the factory's laboratories.
