Flanges Hydrostatic Test Pressure

You need a new QA/QC team.Otherwise,all flanged piping would be limited by 2/3 of the flange rating,which is quite silly.Test to the B31.3 pres1Is it valid to compare the value of test pressure obtained using B16.5 paragraph 2.6 with a test pressure obtained using B31.3,(in the same pipingTable F2 gives operating pressures not test pressures.B16.5,para 2.6 is about hydrotest as you mentioned.You can hydrotest a B16.5 CL600 flangeMost folks around here tend to set the design pressure at the hot flange rating and the test pressure at 1.5 times the cold flange rating. FlangesI concur with Snorgy.To keep things simple we usually test to 1.5 times the cold working pressure rating of the flange unless the pipe is weaker trneill concurs with mebut only to the point where things still make sense. In my subtly sarcastic message and hypothetical example,desigI kind of skipped over the subtly sarcastic part of the message and responded to the more general issue of testing to flange rating :)Kinda what I figured.The OP (vargaslu) put some rational thought into the question and the issue.

Methods for Checking Flange Leakage What Is Piping All

Basically,Flange Leakage is a function of the relative stiffnesses of the flange,gasket,and bolting.Flanges are designed to remain leak-free under hydrostatic test pressure when cold and under operating pressure when hot.The design of flanges (ASME B 16.5) does not take into account the bending moment in the pipe.Hydrotest pressureOct 04,2008 Flanges Hydrostatic Test Pressure#0183;Hydrostatic leak test pressure shall be determined per the applicable code but shall be at least 100 psig (690 kPa),except as follows 1) For ASME B16.5 material groups 1.1 through 2.5,the test pressure for Class 150 piping systems up through size NPS 24 shall be equal to 1.5 times the working pressure of Class 150 flanges at 100degF (37degC).Hydrotest Equipment - Hydrotest ProsThese flanges have specific pressure ratings,including 150,300,600,and 900 series,needed to run smoothly.About Hydrotest Pros Hydrotest Pros specialize in hydrostatic testing equipment and many other services,such as pressure testing,pigging,dewatering,chemical cleaning,and commissioning.

A hydrostatic test could be a method during which pressure vessels like pipelines,plumbing,gas cylinders,boilers and fuel tanks may be tested for strength and leaks.The check involves filling the vessel or pipe system with a liquid,sometimes water,which can be bleached to help in visual leak detection,and pressurization of the vessel to Hydrostatic test and proof test or burst test for pipe Hydrostatic test or hydro test is not required for pipe fittings unless specifically requested by the purchaser.Code mandate that fittings shall be able to withstand under pressure required by applicable Piping Code.But all manufacturer has to prove his design that fittings are able to withstand rated pressure by the proof test.Hydrostatic test and proof test or burst test for pipe Hydrostatic test or hydro test is not required for pipe fittings unless specifically requested by the purchaser.Code mandate that fittings shall be able to withstand under pressure required by applicable Piping Code.But all manufacturer has to prove his design that fittings are able to withstand rated pressure by the proof test.
