Below you will find universal lids that can be mounted on containers/tanks/aluminum coolers and other cooling systems. There are welding flanges that fit plugs that have a pressure relief valve for venting if the pressure in your system becomes too high. There are also welding flanges with lids without an overpressure valve, these are used if you make a system where there can not be too much overpressure. Our welding flanges are typically made of aluminum - If you want to get welding flanges without a pressure relief valve in stainless steel, we can also provide this. When welding flanges, it is important to spot weld the flange firmly before full welding so that it does not become skewed when exposed to too high a temperature.
