Hurry up and do your analysis now before the code case that is up for ballot at the standards comittee is approved and comes out if it is indeed approvedyou will notss have little choice in the matter and will be applying 0.

The properties ofthat bellows are then inserted into the notees model. The logic diagram shown in Figure should serve as a guideline when setting up and analyzing wind load cases to satisfy piping code requirements. Therefore, code compliance requires that the piping system be checked for both types of loading — primary and secondary. The output also provides a code check calculation for the appropriate piping code, from which the analyst can determine which locations are over stressed.

Since this is a displacement load, it is a secondary load, and therefore is not ontes here. The force is estimated as such: The maximum allowed load range may be used in certain situations, such as to permit the use of variable support hangers instead of the more expensive constant effort support, srminar when an alreadyowned spring is to be used over a new one. JUNA AMIKO PDF In order to size each spring for i ts share ofthe distributed weight ofthe whole assembly plus the connected piping, it is best to simulate the stiffness of the duct semonar the use of an equivalent structural member or piping element.

Several examples should help illustrate: You are nites logged in. They have calculated the maximum allowable piping weight notex based upon the following criteria: The stress isometric often summarizes the piping design data, as gathered from other documents, such as the line list, piping specification, piping drawing, Appendix A Figure of the applicable piping code, etc.

The actual installed load case should be run with the cold spring in order xoade determine the installed hanger settings in the presence of cold spring. The first concern is to locate them near concentrated loads — supports should he located as close as possible to the two valves for example, near node points 20 and Occasionally, the manufacturer provides allowable movements only for axial displacements.

The linear force per foot, f, is calculated for each end of the element and the average taken. Therefore, if a rigid support can be chosen instead of a spring at a location, the engineer will usually want this to occur.

Factor Cycles 1 0. For a piping application, the implication of the Soderberg line on the fatigue allowable is implemented in a conservative manner. The bending stiffness that should be used is exactly four times the hending flexibility. This is also in reality, a difficult problem to design for.

In fact, the solution to a problem caused by one of the loading types often causes a problem with the other loading type. This problem is discussed in Section 2. In less pronounced cases such as those shown in Figures B and Cdeviations from the response of an unstiffened bend is usually ignored. Potential causes of failure are bending stresses in the flange, localized stress concentrations in the hub, ccoade of the bolts, or unloading of the gasket, causing leakage.

It is an engineering decision. The basic steps involved in doing code compliance are outlined below: In this case, the equations given in Section 3. TOP Related Posts.

Indicate where additional definitions stiffness, gap, etc. The restraint type or vector may follow any line by defining direction cosines. They may be signed to provide restraint in only one direction. A restraint with no stiffness listed will be assumed rigid.

Kejar This section looks at the various ways providing coadf degrees ofaccuracy in which sample piping configurations might he modeled. For Service Level C Emergency: This discharge initiates ajetforce, which must be resisted by the piping system. This model can only be usedifthe effects examined are limited totwo adjacent support points and the straightrunofpipebetweenthose support points. Expansion joints may vary in terms of the number and type of convolutions, the noets, the number of plies, all ofwhich effect the pressure capacity, the stiffness, and the allowable movement. Expansion joints resemble bellows and provide very flexible pipe legs within very short leg lengths. I neglects all forces, while in the default interpretation, B Center of Bending D B Figure The computer algorithm assumes that points A and B of Figure always lie on the seminaf cross-sectional plane, whether in the deformed or the undeformed state.
