I would like to ask whether this large body casting do radiographic examination, if not how to detect internal defects in the body. If the shell strength test can detect sand holes and other defects not? Class is 150LB.
It is recommended to do the flaw detection, and sometimes the water pressure can not be done, coupled with the higher temperature of the working conditions, then slight defects may also be leaked
Do test strength of shell on the line, playing water to see if there is no sand leakage. If the medium is oil eye small medium density etc.,
See general valves used in site is important, take what kind of medium.150 pounds of pressure is low, estimated to be not what important parts, generally do not need to do testing, the testing cost is not low.
