By Derrick Taylor, PneuTech USA. An air receiver tank (sometimes called an air compressor tank or compressed air storage tank) is a type of pressure vessel that receives air from the air compressor and holds it under pressure for future use. The tanks come in a range of sizes and in both vertical and horizontal configurations.
Pipe diameters are generally 250 to 1219 mm for nominal pipe sizes. The two-phase line can be in the range of 50 to 150 meters, the steam lines from 2000 to 3000 meters and for the brine up to 6000 meters long. The total cost of pipe installation can be US$ 600 to US$ 1,200 per meter of pipe.
