Important Points SOP (Standard Operating Procedure) During the Inspection of RCC NP4 Pipes: -    Image-Hydro Test (Photo Credit: Ritesh Raj) (1.) Firstly, approved QAP will be checked.  (2.) ID marks should be marked on the inner and outer sides of pipes.  Image-ID Mark (Photo Credit: Ritesh Raj)  (3.) To check the inner and outer diameter of pipes.   (4.) Smooth finishing and before dispatch of RCC pipes cement slurry or grouting where required.   (5.) Load test is required for RCC pipes as per IS codes. It is different for each dia, of RCC pipes.  Image-Plate Load Test (Photo Credit: Ritesh Raj)   (6.) Concrete mix design checked and in which cement content, cement brand, and water-cement ratio should be checked.  (7.) The straightness test to be checked of RCC pipes through the straightness rods to collinear visible.   (8.) As per requirement 2% of hydro tests are to be checked as IS:458 of the total...
