Re: [MW:14284] API 650 - Vacuum box test - How vacuum is created by feeding air by air compressor


Dear 
The velocity of air inlet is more than inside of the box. So it evacuate the air inside the box and create vacuum. We are not passing the air directly inside, air passed through the straight pipe and a branch only connected with it. The simple mechanism like our bed buck sprayer pump (mini).
