I got the tank off the trailer and it's been sitting open for a couple of months. I opened up all the ports and got ride of all the left over gas and all the smelly sludge. I have filled it up with water and drained it - so there should be no more gas left in it.
The tank is 2200 litres (581 gallons).
My next step is cutting the doors and welding the hinges so i can burn it all out.
i have done a bit of reading and correct me if i am wrong.
Step 1 - mark all the doors up in tape as a guild line
2 - cut the top of the door
3 - weld a hinge above the cut line, taking into account i will have a steel strip with fire rope underneath to seal the doors.
4 - once hinge is welded on cut the rest of the door
My real question is at this stage - how big should i make the doors?
I was thinking probably having 2 doors instead of 3 as it's a lot more work.
Can you please tell me what size doors do people recommend? I think width wise it will be easy as i will cut 2 inch from the weld seam and piece in the middle about 20 cm (7 inches). Really i just need to know how high and do i need to cut?
I was thinking maybe cutting not directly at the top of the tank but maybe 7 inches below and the bottom cut until it hits the half way point?
