How is the number of radiographs required for each weld joint of various pipe sizes determined in the radiographic testing (RT) process? What is the basis? This post was last edited by cnpc100 on 2009-4-1 11:31.]

Just find JB/T4730 by yourself and do the calculation. This standard is available in the forum

It should be mentioned in the standards!

Find the explanations or supplementary regulations in the installation manual for fixed-diameter pipes; they specify the dimensions and number of X-ray inspections required for welds of various pipe sizes.
