High Pressure Testing

High Pressure Testing

High Pressure Testing

(OP)
Does anyone know of a good safety site for testing at high pressures?  We test anywhere from 25 psi to 2500 psi.  Our current unoffical policy states that if the pressure is over 100 psi, then a safety shield is needed. No mention of thickness or size is taken into consideration.  Just wondering if anyone else has dealt with this.  Thanks.

RE: High Pressure Testing

you are not stating what you are testing and what type of media is used in pressure testing.  Without knowing these basic facts I can not come up with an answer to your question

RE: High Pressure Testing

(OP)
We test a lot of different materials at a lot of different pressures.  Tops is about 2000 psig and the lowest is around 10" H20.  Stainless to aluminum on material.  Tubing to fittings to cylinders for parts.  

RE: High Pressure Testing

The are a lot of documents that treat this question. For example, API RP 920 "Prevention of Brittle Fracture of Pressure Vessels ", says that you must have care with low temperatures in, for example, pressure testing.
I think the way is to analyze each case, each material and each fluid, and the consequences of fail during a pressure test, using design conditions (for example ASME), accumulated energy during the test, and material properties.

RE: High Pressure Testing

But what medium are using for testing the various materials?Is it also hydrostatic tests, mechanical pressure tests, and what devices or methods are you using?

RE: High Pressure Testing

I agree with you, chicopee. You need complete data to deal with this subject. For example, we use self-made metacrilate screen to protect from a shot of tube caps in a tubular exchanger hidrostatyc test.
