Test Piece Cutting Saw
Test Piece Cutting Saw
This Test Piece Cutting Saw is the stationary dual blade milling type, the test pieces are used for destructive and tensile testing, and cutting out UST defects. These test pieces are automatically cut by the saw which is integrated into the conveyor system after the pipe mill flying cut off. The pipe length required for test pieces is added to the nose and tail of the butt weld which also includes a full length of good tube. This tube is delivered to the Test Piece Cutting Saw using the feeding conveyor. When the pipe reaches the feeding conveyor it is accurately positioned using an encoder controlled feeding mechanism. Two test pieces required for destructive testing are cut from each side of the butt weld, then the good tube is cut to the correct length then after cutting the test pieces, the good pipe is returned back to the conveyor system, the butt weld is sent to the scrap bay and the test pieces are safely delivered to the operator’s side of the machine through a delivery chute. One test piece is also taken from the middle of each coil of strip for destructive testing. The cycle time for cutting the test pieces is much shorter than the typical band saw that is in common use. As a result, destructive testing can be conducted faster saving time and giving mill operators more timely feedback. The shortest test piece cut length is 100mm or less for any O.D. within the machines specified range, thereby saving material. Added to this is the material saved by being able to accurately cut a length of good pipe from the pipe containing the test pieces and the butt weld.
