Hello, we need some advice please. We have a 100 cfm atlas copco rotary compressor that we have recently purchased second hand. We are going to be using it mainly for sand blasting. At present we do not have a air receiver tank that is big enough, the suggestion is that we need a >500L receiver tank. The maximum pressure we will be running in these tanks is 125psi.
We have a reasonably well set up machining workshop, the issue is that we are contemplating fabricating our own receiver tank as follows.
200mm diameter seamless pressure pipe, with 8mm wall thickness, the pipe is tested by the mill to 1570psi (this is a API 5L rated pipe). We were then going to weld 8mm plate to each end to create the cylinder ends (yes flat ends). The proposed length is 2m and then link 8 of them in series, this effectively creates 1000L of air receiver tank.
We have a 325amp 3 phase MIG welder and are reasonably competent with it. It is proposed to chamfer the ends of the pipe slightly and also allow a 2mm gap to provide a solid root weld then fill with two further welds to complete the fillet weld.
Any thoughts on this would be welcomed.
Thanks
Peter
