Seismic Loading-Static Equivalent with Operating Case Specified In this field, the User may place a check mark to instruct TRIFLEX® to consider the effects of User Specified percentages of gravity along the X, Y and Z axes as an occasional load. By checking this check box, the User instructs TRIFLEX® to apply the multiplied by the factors entered by the User on the occasional loading dialog. To find this dialog, click on “Setup” and then “Occasional Loading”.

Spring Hanger Data Immediately below the data group entitled “Rotational Restraint Action”, the User will find a data group entitled “Spring Hanger”. The fields in which data can be entered are , , , , , and . Spring Hanger Manufacturer If spring hangers are to be and selected in this piping stress analysis, then the manufacturer of the spring hangers from whose product line the selection and sizing is to be based must be selected by the User from the drop down combo list in this field. When a spring hanger vendor is selected, TRIFLEX® will choose the proper size and series spring hangers from the specified vendor’s available selection. The selection of the required hangers will be based upon the load being carried and the necessary installed-to operating travel as determined by TRIFLEX®. (Note: Basic Engineers is no longer in business, but there are still attributes in TRIFLEX® which will enable you to work with Basic Engineer’s Springs.) Bergen & Paterson Bergen - Power Piping Comet Support Springs Carpenter & Paterson (AAA Technology) Flexider (Table 5) Flexider (Table 6) Flexider (Table 5, revised) Grinnell Inoflex Lisega Nordon

When a value is entered in this field, TRIFLEX® will simply apply the entered load. No calculations for projected area will be performed, no shape factor will be considered and entering pipe insulation will have no effect. Wind load must be entered as a positive number. Wind Load and Uniform Load Buttons The data is organized in related data groups on this dialog. On the first line of the Wind Load dialog, TRIFLEX® provides three radio buttons for the User to select from. The default is “None”. If the User wishes to Wind Loads, the User should click on the Wind Loading radio button. If the User wishes to enter Uniform Loads, the User should click on the Uniform Loading radio button. If the “None” radio button is selected, all fields on the dialog will be grayed out and inaccessible by the User. Wind Load calculated by TRIFLEX® Wind Load: (lbs. per linear inch of pipe) calculated by TRIFLEX®:where: V1 = Wind speed supplied by user in the Wspeed field to accommodate extraneous factors. (Suggested Wspeed = V x I x sqrt( (Kz). When the User enters Wind Speed, TRIFLEX® will automatically calculate additional loads and stresses that result from the wind loads. The true effect of the wind loads will be projected onto the piping system.
