About Circumferential Welding Machine, With the development of the times, the issue of protecting the environment has been recognized by all countries in the world. International organizations continue to promote the development of new energy and sustainable use of energy. In the 21st century, the birth of LNG steel cylinders has greatly improved the problem of environmental pollution. Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.
Improved Air Quality. Natural gas is the cleanest-burning fossil fuel, therefore vehicles running on LNG produce lower levels of toxic emissions and air pollution than equivalent diesel engines. Nitrogen Oxides (NOx) emissions are reduced by 40-50% and articulate Matter (PM) emissions are reduced by approx 80%.
In order to meet the market demand, we have fully upgraded our Circumferential welding machine. Taking into account the high requirements of LNG Cylinders, we have carried out a long time on the Rolling of the cylinder body, the straight seam welding, and the circumferential welding with the two domes of the cylinder. After 8 months of research, our welding technology has been approved by many domestic Well-Known LNG Cylinders manufacturers.
From the assembly and spot welding, the domw is automatically pressed and assembled, and the position of the welding seam is automatically scanned and automatically compensated, and the cylinder body is rotated and positioned. After assemblied and spot welded, next step is looking for the well welds. Circumferential seam welding machine can adopt special machine welding r robot welding form, and the cylinder can be automatically by manual assistance or by aerial manupulator. It can be configured with contact or non-contact welding seam automatic tracking system to automatically locate and track the welding seam position to ensure each welds is match the designd quality.
