Good afternoon, I have an elbow in material ASTM A403 WP321. The maximum design temperature is 450°C and on ASME B31.3 Table A-1 I found its allowable stress for design calculation: 16.7 ksi. Up to now everything ok. During following production testing I have to find, in addition to room...

Good morning, I refer to everyone who is used to work with weldolet. My question regards the interpretation of MSS SP97 standard. In this standard, para 3.2 of 2006 edition, it's written "The run (header) pipe size is limited only by the pipe size range listed for each type fitting class". Does...

Good morning dear all, regarding impact testing of materials according to ASTM A860 and/or MSS SP75, does anyone know if there can be an empirical link (for example through interpolation) or a mechanical link between the values of absorbed energy (in joule), and shear area? In other words...

Good morning, I have a question which can regard both ASTM/ASME forum and Materials forum. We produce seamless carbon steel fittings according to ASTM/ASME A/SA420 WPL6, suitable for low temperature service up to -50 deg. °F. Our starting pipe is according to ASTM/ASME A/SA333 gr. 6: our...

Good evening dear all, I have a question regarding HIC (Hydrogen Inducted Cracking) test on carbon steel plates (ASME SA516). Provided that the chemical composition of the steel is satisfactory (low sulphur content...), is it necessary to heat treat (normalize) the plate before performing the...

I'm in accordance with Steve Jones and with what he said in "Metal and metallurgy eng. forum" thread 330-166078 (my question is the same as in this forum). I hope some more persons can help us to clarify this matter... thanks Gianluca

Thanks Jones, I appreciate your help. I also put this question in the "QC Inspection & Testing forum". Now we wait for new replies. See soon Gianluca

Talking about tensile tests according to ASTM A234 WPB; if I make a butt welding fitting starting from a plate with wall tickness 25 mm, I have to normalize (heat treatment) this fitting. Very often the plates are furnished as rolled, not heat treated, but the tensile tests reported on the 3.1...
