profile360™ measures outer diameter and out of roundness of a pipe both in-line (on the mill) and in final inspection. When used in final inspection, Profile360 produces an automated dimensional inspection report for the Outside Diameter (OD) and Out of Roundness (OOR) of the pipe ends and body to assure compliance with API and other standards.

Calculate API 5L line pipe out of roundness and ovality from diameter and tolerance. Out of roundness is equal to the maximum diameter minus the minimum diameter measured at the same cross section. Out of roundness ratio equals the out of roundness divided by either the nominal diameter or the mean diameter.

2019年3月2日 · Tubes, pipes or solids will have a range of values that would be acceptable and considered as ‘x’ nominal OD. Roundness tolerance (+/- 0.01 inch) would mean the difference between major OD and the minor OD throughout the profile should not …

A single measurement cycle instantaneously acquires about 5,000 data points in-plane for a 24” pipe and can report up to 180 diameter values, one per degree. For final inspection the software displays maximum, minimum, and average OD and OOR for each pipe end and the body.

Calculate API RP 1111 limit state pipeline out of roundness and ovality from tolerances, or from maximum and minimum diameter. Out of roundness is equal to the maximum diameter minus the minimum diameter measured at the same cross section.

2018年5月18日 · Simply put, ovality occurs when a pipeline ‘ovals’ from its original circular shape – the pipe is no longer perfectly round. Although any pipe will oval under the right amount of loading, pipelines with high D/t ratios (diameter over thickness) are most susceptible.

Calculate API 5L line pipe unit mass (mass per length) and total mass from diameter, wall thickness and density. Pipe mass can be calculated with API 5l tolerances, or as mass schedule with no tolerances.

ovality turns into barrier of proper welding of two pipes on site. In this paper, there is inclusion of causes of ovality, stages of ovality, drawbacks of oval pipes, manufacturing difficulties due to ovality and how to control it is included. Keywords—Ovality, L-SAW pipe, Spiral welded pipe, Expander, Hydraulic press, Cross-weld.

Quick change-over from one pipe-end treatment to the other. Safe pipe end surface treatments. Autonomous system, no need for settings or adjustments by personnel. Simple to operate, no robotics expertise required! Together we quickly came up with a concept of a robotic arm with a sort of claw attached to it to grip the caps and remove them.

2018年2月27日 · Out of roundness is the difference between the maximum and minimum diameter of the pipe. API 5L ovality is calculated by fapi = (Dmax - Dmin) / (Dmax + Dmin) = OOR / (2 Davg)
