WHAT ARE THE MEASURES AND WAYS TO MAKE PITTED AREA/SPOTS ON PIPES TO MAKE IT SAFE TO AVOID LEAKS AND OTHER HAZORDS,AND HOW PITTING ACCURES WHILE PIPES ARE LYING OUTSIDE THE GROUND(EARTH),AND HOW IT STARTS IN THE GROUND.
WHAT IS THE BETTER WAY TO REMOVE PITTING FROM PIPELINES OTHER THAN SAND/OR RUBBING WITH HARD STONES ETC,ALSO MENTION THAT THE WEAK POINT/SPOT WHICH HAS LOST THE STRENTH OF THE PIPE FROM THAT PARTICULAR SPOT,HOW THAT STRENTH CAN BE REGAINED.
THANKS
I MAY PLEASE BE GUIDED THAT THERE ARE HOW MANY KINDS OF CORROSION.SPECIALLY I WANT TO KNOW THE TYPES OF SUCH CORROSION WHICH EFFECTS ON NATURAL GAS PIPE LINES.
