By JL automatic welding lines, the unique technology, welding forming a Cover 2. Solid welding, weld smooth formation, no scar, no tumor. Longer life of the water heater, while stronger pressure capability, to achieve a maximum of 21 kilograms, can ensure that the international standards liner dynamic pressure test.

Uses the JL entire automatic adherent wire, the craft is original, atwo end covers welding takes shape. Welds reliably, the welded jointsmooth is smooth, does not have the scar, does not have the lump.Water heater service life longer, simultaneously the pressureresistance ability is stronger, the most high energy in achieved 21kilograms, guarantee the gallbladder to be able to move the pressuretest through the international standard.
