Pipe portable Brinell hardness tester is a kind of hardness tester special suitable for on-site testing of steel Pipes, bearings, gas cylinders, and the work principle as below:
WORKING PRINCIPLE
Fix the test head of Brinell hardness tester to the test frame. When testing, fix the measuring frame onto the surface of the test piece firmly, load force by operating the handle.
The test head is a mini hydraulic system which contains a control valve for controlling force. When force loading to 3,000 kgf, the control valve opens, pressure releasing. According to ASTM standard, force loading should be repeated 3 to 4 times, keeping the pin of the pressure gauge reaching the point of 3,000 kgf 3 to 4 times. In this way, it equals the test regulation of test force 3,000 kgf, 10mm test ball, force maintaining time 10 to 15 seconds.
