Piping dimensions

The Calibration of the positioning system is carried out using a bar with a given distance which is placed between the referenspoint on the microphone collar and the probe. The distance is then entered into the acquisition software together with informations of the air temperature close to the tested object, pipe dimension, type of UT-probe (probe height) and scanning direction. 

If possible, this can be done by building a 1 1 mock-up of the measuring position, using the same pipe dimensions and material as in the process part. The mock-up should then be filled with a suitable liquid, in this case gasoline or light petroleum, to which a precisely measured amount of tracer is added. This way, the response towards a known dilution of the tracer can be found.

When an industrial pipeline is to be designed, there will be no a priori way of knowing what the in-line concentration of solids or the slip velocity will be. In general, the rate at which solids are to be transported will be specified and it will be necessary to predict the pressure gradient as a function of the properties of the solid particles, the pipe dimensions and the flow velocity. The main considerations will be to select a pipeline diameter, such that the liquid velocity and concentrations of solids in the discharged mixture will give acceptable pressure drops and power requirements and will not lead to conditions where the pipeline is likely to block. 

Estimate the exchanger area from an assumed value for the overall heat-transfer coefficient. Decide the exchanger layout and piping dimensions.

Here is a inciliod lo esiimate the maximum allowable pressure for ferrous piping according to ASME and ANSI codes without referring to the actual codes stress tables. In addition, specific pipe dimensions (O.D. and thickness) need not be known, as the schedule number and pipe material are all that are necessary. 

Allowable stresses and values of the coefficients for different materials are given in Appendix A of the design code. Standard dimensions for stainless steel pipe are given in ASME B36.19, and for wrought steel and wrought iron pipe in ASME B36.10M. Standard pipe dimensions are also summarized by Perry and Green (1997).
