Already a member? Discover how this hybrid manufacturing process enables on-demand mold fabrication to quickly produce small batches of thermoplastic parts. Non Destructive Testing - Pressure Testing is a non-destructive test Could anyone advise me the Calculation of SAFETY DISTANCE for pressure testing; Based on my knowledge the following Code covers the equation; a) ASME PCC 2 Article 5.1, Mandatory Appendix III - Pneumatic safe distance. The deeper we are, the more such particles are above us, and the higher the fluid pressure (because the acting force is greater - see our pressure calculator). For pressure testing of a component that will be used in service, the pressure is usually 1.3 - 1.5 x design pressure, which keeps the material from yielding, but subjects it to more stress that it will see in service. Enter your email address to JOIN this blog and receive HSE notifications and HSE job by email. Pneumatic testing is inherently more hazardous than a hydrostatic test of the same conditions of volume, pressure, and temperature so appropriate safety precautions are .
