Profile: Birchley Products specializes in design services. We supply test equipment products. Our test equipment product includes cylinder test unit, master gauge, pressure tank, shot blasting, drying machine, corrosion device, cylinder inspection, thread gauges, and cleaning machine equipment. Our shot blasting machine product cleans all the internal surfaces of the diving cylinder. It removes rust, general contamination, base materials, and corrosion build-up dust. It is boosted by a higher additional air pressure via a mixing valve, and a venturi action ensures optimum results. Our corrosion device measures the internal pits inside gas cylinders. It moves from the vertical through 90 to a retro position of approx 135. It is a breakthrough in the measurement of internal pits in both aluminum and steel constructed gas cylinders. Our cleaning machine is dedicated to cleaning diving cylinders which use enhanced oxygen mixtures. It sprays the de-greasing fluid into the cylinder, and uses a pressure pump to clean full percentage of the internal surface of the cylinder. It consists of a holding tank with water heater installed tank.
