Hi, What is the differenc between a SS Impulse tube and SS pipe . We have used 1/2" inch Pipe instead of Impulse tube ,with the thickness satisfying the Pressure requirements.Does it will affect the operation of the lines since we had to bend these pipes as per the requirement. As far as I know ,the material properties are same for both pipe & tube ,only thickness varies in tubes depends on the design requirements and for pipe we have to take the matching sizes with respective SCH from the standards. Also is there any difference in manufacturing or in properties of Impulse tube from normal tubes , or it is the same tube but only called as impulse tube based on application. -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

Hi Vino, I believe your query is on repair/alteration and rerating of an existing piping? If so follow the guidelines of API-570 as attached. Additionally follow the flow chart of ASME PCC-2 and the recommendations of article 5.1 of PCC-2 for more guidance. One should not repair/ alter and operate a 25+ year plant  same as a new construction .   Following repair, one may perform pressure test at the MAWP, or rerate the piping or component and accordingly proceed for testing.   I would thing attached API 570 guidelines and guidelines of PCC-2 codes would be of help.   Thanks.     P.Goswami.P.Eng, IWE.
