Finished pipe OD WT length, surface quality, Straightness, polishing the defected pipe Visual and Dimensional Inspection. 1. OD tolerance: (-0.75%D,+0.75%D). Pipe ends OD tolerance: ±0.005D. 2.WT tolerance: (+15%t, -12.5%t). 3. Ovality of pipe body: ±0.020D, Ovality of ends: ±0.015D. The WT at any point of the pipe shall be more than 87.5% of nominal wall thickness. WT on pipes ends is measured with micrometer. Wall thickness measuring on pipe body is performed by manual UT for WT covering 3 rings or section all along the pipe body with 6 readings at each section. 4. Pipe body bend degree:0.20% of the pipe length Measured with a taught line. 5. Pipe end bend degree : Should not be more than 3.0mm in 1.2m. Measured with a straight bar.
