Asme vs astm materials
The questions still stands. How to derive allowable stresses at temperature from ASTM specifications when the material is not listed in ASME code? There are thousands of materials which ASME does not list currently (they are behind the times). ASTM does. ASTM lists temperature ranges in...- Redavocado

Valve stem rating
Regarding valve stem design, it is always a good practice to do standard thread and / or seat shear calcs using the weakest material in shear. When the valve stem is under internal pressure a shear force is applied to the bonnet arrangement. OTher than that, ASME B16.34 covers bonnet...- Redavocado

Hazardous location pipe fittings?
Greetings, The key to the applicable code is identification of the vertical market. For oil, gas and petroleum you may consider API, ASME B31.3, and ASME B31.8 codes of construction for fittings, whether electrical or not. Fittings may include diaphragm seals, instrumentation, actual fittings...- Redavocado

EN to ASTM/ASME
Does anybody know a good central reference which correlates mechanical and chemical properties of EN materials to ASTM/ASME, along with allowable stresses?- Redavocado

Asme vs astm materials
I have an ASTM material used in a fitting at an elevated temperature. It is not listed by ASME so it doesn't have an ASME allowable stress atelevated temperature value. I may determine the allowable stress from the ASTM specs using ASME b31.3 2*Sy /3 or St/3 min. But how to get the Sy at a...- Redavocado

Bronze valves
Trying to qualify bronze balancing valves to b16.34. All materials are EN and material certs are EN no mention of ASME or ASTM. To get CRN would it be possible to show equivalence of mechanical properties and use the lesser tensile values and allowable stresses to determine body wall min...- Redavocado

Why does a high tensile value yield a low MAWP?
In UG-101 m a high actual average tensile strength will yield a lower MAWP for a given burst value. If, say, I get the MAWP for a fitting using a sample w a low tensile value, but in production I procure the same material that was burst but w a stronger tensile strength according to UG-101...- Redavocado

Ug-101 m tensile values
We are being required by ABSA in Canada to provide actual tensile test values from the average of 3 samples cut from fitting which have been burst tested per UG-101 instead of the maximum tensile value provided on the mill certification of the raw material used for the fabrication of the burst...- Redavocado
