    B31.3 345.3.1 (b) Joints Exposed Question

    Thanks for everyone's input, much appreciated. To answer some of the questions/comments: XL83NL - Good point, however I believe you mean API 570. I will have to look into this. It has been in service. LittleInch - Sorry, I didn't think much detail was required as I was only concerned with...

    B31.3 345.3.1 (b) Joints Exposed Question

    Hey all. We are looking to re-rate a section of piping to a higher MOP. Currently all of this piping is insulated and I am trying to determine if I need to remove all of that insulation or if I can test in place. Our new MOP will still be lower than the ANSI rating for that section (why they...

    Required Leak Test - Threaded piping, Nipples, etc.

    Good day. I found some topics here but none of them seemed to answer my question. Note this is for B31.3 Normal Fluid service. I feel section 345-Testing in B31.3 does not do a well enough job describing testing requirements for threaded piping. I think I have 2 basic issues that need...

    Actuated Valve Tagging - ESD, SBV, etc.

    Thanks fellows. I found ISA 5.1 after my OP but I didn't find it helpful as it doesn't even discuss "emergency" and only discusses safety valves in terms of a spring PSV. As both you point out it looks like there is no real standard for "emergency" valves and it all comes down to our company...

    CSA Z662 - Reducing Flanges Interpretation

    LittleInch - No offense and I appreciate your feedback but when you state "the mysterious hub of indeterminate dimensions" I get the feeling you may not not have the experience I am looking for to answer this question? You are correct there is no specific code (that I know of) that outlines the...

    CSA Z662 - Reducing Flanges Interpretation

    Thanks for the feedback LittleInch. I don't want to sound rude, but I would hope that anyone who can answer my question would know what a hub blind flange is...maybe it was just confusing because I didn't specify "blind"? Sorry if so. To be clear a hub blind flange is basically a blind flange...

    CSA Z662 - Reducing Flanges Interpretation

    I hate to bump this thread but I haven't received any feedback.

    Actuated Valve Tagging - ESD, SBV, etc.

    Can someone help point me in the right direction on whether there is a standard on the proper naming convention for actuated valves that are used for certain purposes? For instance if an actuated valve is used for an emergency situation and meet certain criteria (such as it fails last) it must...

    CSA Z662 - Reducing Flanges Interpretation

    If there is one thing I hate about being an Engineer it is interpreting Codes, lol. I am being asked more and more from the field on if tapped flanges, centerline or off center, can be used. I feel I have a decent understanding on the requirements laid out in B16.5/B31.3. However, I am a...

    B31.3 and/or CSA Z662 - Pressure/Leak Testing on Threaded Piping

    Thanks DekDee. I figured the answer was pretty straight forward but needed some confirmation.

    B31.3 and/or CSA Z662 - Pressure/Leak Testing on Threaded Piping

    Where is this project located? - My question is just based on B31.3 and Z662, and at this point I'm not looking at any jurisdictional regulations. What are the local Codes, Rules, Laws and Standards regarding this subject? - As above What is the commodity? - Normal Fluid Service What is the...

    B31.3 and/or CSA Z662 - Pressure/Leak Testing on Threaded Piping

    Pressure/Leak testing has always confused me and I'm hoping someone can give me the likely easy answer? Testing requirements (the basics) are relatively the same for both B31.3 and CSA Z662 so I assume the answer doesn't change between the two? I think the answer is simple but thought I would...

    CSA (PN) Flanges and ANSI Flanges

    Ok, so I have attached a photo of the MTR I received for one of my flanges. Maybe this will help to explain my issue and hopefully someone who has purchased these before can ease my concerns? The vendor has stated this is a dual rated flange. The flange is stamped with both B16.5 information...

    CSA (PN) Flanges and ANSI Flanges

    Can anyone provide clarity on what determines the flange can be rated to 120C before deration? Is it the CSA Z245.12 or the PN designation that determines this?
