IMO 311 should have ALL the acceptance standards not everything except porosity on RT. If you are doing a penetrant test on steel structure then you should look for acceptance criteria in the AWS D11. ASME B311 Test Power Piping The hydrostatic test pressure at any point in the piping system shall not be less than 15 times the design pressure but shall not exceed the maximum allowable test pressure of any non-isolated component nor shall it exceed.

However the surface of welds shall be sufficiently free from coarse ripples grooves overlaps abrupt ridges undercut and valleys. 1 Have no indications. ASME B313 code does not specifically say about any limit of allowable sagging.

As per the latest ASME B311 2018 edition there is a update in occasional stress equation due to occasional loads which now includes the defined term Po representing the pressure coincident with the occasional load being evaluated in psi kPa. 113 The thickness of reinforcement shall not exceed. New Mandatory Appendix O Use of Alternative Ultrasonic Acceptance Criteria.

The criteria addressed in clause number 34442 -. That alternative approach typically results in allowable flaw sizes that are somewhat larger than the workmanship criteria but still small enough to survive a test to SMYS. Liquid Dye Penetrant Testing Acceptance Criteria is given in ASME B311.

Rounded Indications Eg Porosity Slag inclusion. The pressure limits are different for ASME B311 and ASME B313. Learn from industry leaders earn continuing education units.

The basic allowable material stress value as per ASME B311 is lower For example the allowable stress value for A 106 B material at 250 Deg C is 117900344 Kpa as per ASME B 311 than that of ASME B313. 1 Criteria given are for required examination. 112 The surface condition of.

Refer the table below from AWS D11 for the acceptance criteria for Liquid Penetrant Testing the acceptance criteria for visual testing also. In this case it appears a fitness for service approach is not an option for B311 or B313 so we will move on and use a conventional approach toward weld flaw assessment.
