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.
