01 LNG Gas cylinder machinery produaction line

The LNG cylinder production line of EN source company is used to store liquefied natural gas.
As we all know, liquefied natural gas is the most environmentally friendly and clean energy in the world, but the transportation and storage of natural gas is relatively difficult, and it needs to maintain a constant temperature or cryogenic(low temperature) environment.
The LNG projects provided by our company perfectly solve this problem.

LNG cylinder machinery production line Longitudinal seam welding machine Scope of application: This equipment is specially used for the longitudinal seam welding of the outer tank of LNG welding insulated gas cylinder. Workpiece material: austenitic stainless steel. Workpiece thickness: 2.5mm~6.0mm. Weld joint form: I-type butt joint. Diameter range: φ508mm~φ758mm.

LNG cylinder machinery production line Seam welding equipment for inner and outer bladder Welding process and equipment characteristics: Operation mode: simultaneous welding with two guns, single operation. Equipment jacking pressure: not less than 3 tons (adjustable jacking pressure). The quality of the equipment host: not less than 5.0 tons. Workpiece placement method: the welding torch is fixed and the work piece rotates. Diameter range: φ508mm~φ758mm. The length of the barrel: 500mm~1800mm.

LNG cylinder machinery production line LNG cylinder vacuum system LNG cylinder Equipment usage: The number of vacuum bottles to be pumped in each group is not less than 36. After each group of gas cylinders are vacuumed, the final vacuum at the vacuum plug will reach 5×10-2Pa. The helium leak detection rate of the overall spray gun of the equipment is ≤1×10-9Pa·m3/s. The replacement nitrogen pressure is controlled below the absolute pressure of 80KPa.

LNG cylinder machinery production line Work efficiency of polishing machine Welding process and equipment characteristics: The surface of the workpiece is polished. After the first polishing wheel passes through the eighth one in order, the required finish can be achieved Ra≤0.8 The working cycle is about 20 minutes or so. The equipment is welded with high-quality steel, the surface is finished after welding, and the front and rear feeding racks are 2m each.
