For a specific casting method, the bursting pressure is determined by the nominal pipe diameter and wall thickness.
Those concerns and others aside, INGAA has made a counter proposal which includes submission of some of the new information PHMSA would like to have, such as the pipe arterial, the nominal pipe diameter, pipe coating, whether a low-stress pipeline is using the 30% SMYS threshold and some other items.
Based on this information, the nominal pipe diameter can be calculated.
The axial locations where measurements were made downstream of the elbow are denoted in Figure 1 in terms of nominal pipe diameter, D.
These tools are able to detect and quantify 0.250 inch or 2% dents depending on nominal pipe diameter
There are dual-diameter tool designs for both tool technologies that cover Image variations in nominal pipe diameter, like 25 percent for UT or 15 to 20 percent for MFL, Although there are several dual-diameter kits for these applications available for MFL tools, the UT tool design still offers tire advantage that the dual-diameter capability can be obtained relatively easy as a variation of an existing tool in any diameter, thereby improving the availability and economy for dual diameter applications.
Sensor resolution on radius measurement is 1 mm and sensitivity on detection of bore changes is the larger of 0.5% of nominal pipe diameter or 2 mm.
API specifications allow out-of-roundness to plus or minus 1% of the nominal pipe diameter primarily to eliminate problems when welding.
The recommended piping installation consists of the following: A straight section of ten nominal pipe diameter length is to be installed upstream of the meter as shown in Fig.
