We purchase a 20 bbl, 2 bar brite tank from a reputable american made company. We have had a couple major issues with it. It is currently back at their warehouse getting one problem resolved. The other problem is the manway on the door would take brute strength to close and open. (we would have to kick it and beat it with a mallet to get it open after use) They have replaced the gasket and added a new wing nut and longer handles to the door and it is easier to open now. The big issue is the top and bottom seal first and once you begin to twist the sides close after. The door is not the exact shape of the manway hole itself. They had another company manufacture the door and that company has said it is supposed to bend. I have reached out to an engineer from another company and said that is not correct and it should scare me. Any knowledge on this is appreciated. This is what the manufacturer of the door said:
"Lid on these profiled manways is not radiused, so it will seal on the longer ends. It springs / bends in the middle when you tight the nut and that force keeps ends of the lid tight to the frame. Besides bent lid won’t be any wider. From the picture it looks like the frame is deformed."
It sounds like they are blaming each other but never the less I really don't want to take this tank back with the door bending unless someone really has heard of this.
