We have have a number of stainless steel lines to install but have found carbon contaimnation adjacent to the weld area, it seems like carbon brushers have been used. Can any one advise a suitable cleaning method bearing in mide the site has strict rules on chemicals being used and pickiling is...
Thanks for the indepth reply, i coudnt find the anwser in ASME IX because as you have stated there isnt one. As i rule of thumb from now on i shall refer back to the for times the wall thickness. Cheers
We have a 30" ball valve on site which when trying to install had some minor damage to the drain pipe and vent pipe. Would it be permissible to repair these items and still retain the valve warrenty- insurance.
