The machine is with good appearance welding seam. During the welding process, only the on-off signal has to be provided, the whole welding seam can be finished one time without halfway stop. Which increased the welding efficiency and improved the welding quality. Such circular welding equipment is easy to be operated and installed, can replace a lot of skilled welder.

 
10. Annealing furnace
This furnace is designed to anneal LPG cylinders by applying flame from gas burner on the cylinders. It composes, burner, flaming chamber, smoke collector, rails, chain roller, exhaling system.
It feature includes, adjustable time, self-control thermometer, perfect heat treatment result and fire off pollution.



11.Sandblast machine
Remove the rust, oxide layer and burr free of pipe. Clean welding slag, showing a metallic luster,
make surface achieve a bright and clean surface and to improve the adhesion force of painting to surface and improve the anti-fatigue force and anti-rust capacity of surface, improve the inherent quality of surface and prolong the lifetime of steel tube

12.Power coating machine
Coating the cylinder surface to protect the cylinder from rusting
