Hi all!
I'm trying to find out if the ASME B31.3 code allows for the use of a barbed hose fitting (for a rubber hose that is qualified to B31.3), see attached screenshot. Table 326.1 lists SAE J514 (Hydraulic Tube Fittings), but without buying the standard, I'm trying to find out if it has...
Please see my linked thread below (unanswered) regarding the supplied VERTICAL SDS value for use in a static structural analysis.
[highlight #FCE94F]The main question: Is it good for nothing (with regard to it's use with ASCE 7's static seismic load equations)?[/highlight]

In WRC 537, Table 5 (Local Stresses in Cylindrical Shells), the corresponding image (see below) shows the positive radial load as acting inward towards the vessel.
I am using a pipe stress program to calculate worst-case nozzle loads and have both positive and negative radial force values for...
Hi all!
I am trying to qualify some existing Unistrut P1000 trapeze members for seismic loads. Local buckling is not expected because of the pipes strapped to it every few inches. However, the ASD moment capacity given by Unistrut in their catalog is 5070 in*lbs (422.5 ft*lbs). They also...
Hi All,
I have been given separate horizontal and vertical (site-specific) SDS values to use in my static structural analysis. I am using the ASCE 7 ('05 and '10) equations in Section 13.3.1 for calculating a seismic design force. The definition of SDS below those equations says that it is the...
Let's start with a buried double wall pipe. Let's say the carrier pipe is hot and the encasement pipe is cold. The former expands, the latter contracts. Thermal expansion loops are integrated in the system at calculated pipe span lengths to avoid interaction between inner and outer pipes...
