JOINTECH is leading inspection ISO Certified organization operating in Karachi,Pakistan offering Services for Non-Destructive Testing (NDT) & Lifting Equipment Inspection Services.(NDT Test Methods used for piping products)
Engineers from Hebei Haihao communicated with inspectors of JOINTECH about the new oil & gas project in Iraq.The meeting is focus in how to inspect the flange facing of RF(Raised Face) flanges,including the testing tools and the standards of acceptance.
The flange facing is serration type which have pitch data,after negotiating based on flange standard ASME B16.5 and MSS SP-6 about the facing information,we get a suitable method to test the roughness of the facing.
Finally we got an agreement about this:using the digital calliper to check the pitch depth and space first,then testing the accurate roughness by Portable Surface Roughness Tester SJ-201,a comparator gauge could be helpful in this testing.
Hebei Haihao strictly carrys out rigorous quality control and products inspection to ensure continual quality flanges and pipe fittings.As one of the leading manufacturers in China piping products filed,Haihao always abide by the principle of “Quality First”.
