Reduction of ASME Design Margin - Sperko Engineering

Reduction of Design Margin (Safety Factor) in the ASME Boiler and Pressure Vessel Code in the 1999 Addenda In the 1999 addenda of the ASME Boiler Code,the design margin (formerly known as the Safety Factor) was changed from 4.0 to 3.5.The following is a discussion of the basis for that change.Safe and round with tube and pipe handling?For those working in an environment where tube and pipe is produced or fabricated,the dangers have not been made so apparent,and operators are regularly required to put themselves in harms way,relying on company-established administrative safety measures and their own skills to prevent injury.Safe and round with tube and pipe handling?Worker safety in U.S.manufacturing facilities has improved greatly over the past 25 years,but it's amazing the dangers that still exist in some operations.Tube and pipe facilities actually represent a segment of the fabricating world where some of these risks are most obvious.A look at a couple of tube and pipe scenarios proves what some companies try to get away with and how those safety

Vehicle load is a static distributed load in the middle of the longest tube and is 1/3 the tube length.Loading in the middle of the longest tube is a worst case for stress on a cage member.Square tube assumes bending with one side parallel to the load (think square vs diamond).The safety factors use the numbers in the table below for strength.Tube Calculator - Rogue FabricationVehicle load is a static distributed load in the middle of the longest tube and is 1/3 the tube length.Loading in the middle of the longest tube is a worst case for stress on a cage member.Square tube assumes bending with one side parallel to the load (think square vs diamond).The safety factors use the numbers in the table below for strength.Tubing Products - Hydraulic Supply Companyconsiderable,a 4:1 safety factor (higher working pressures) may be carefully considered.For applications where hydraulic shock and mechanical strain is severe,an 8:1 safety factor (lower working pressures) should be applied.

Working out a Safety factor in a steel tube? Yahoo Answers

Feb 18,2012·Thus,you don't meet the required safety factor,and it's probably not a good idea to stand next to the pipe.On the other hand,steel is a ductile material,and it's possible that,as the load increases beyond the yield point,the load redistributes,which means stress is not linearly related to load.Working out a Safety factor in a steel tube? steel plate It's common to have a safety factor for yielding (permanent deformation,but still able to hold the operating load times the safety factor without seriously compromising the structural integrity) which is relatively low,and a safety factor for ultimate failure (inability to carry the operating load times the safety factor; i.e.structural collapse) which is relatively high.Working out a Safety factor in a steel tube? steel plate Question I am doing a bit of science work i have a steel tube/pipe with a Circumferential(hoop) stress of 63.96 Mpa,if the tube has a 250Mpa tensile strength and a safety factor is 10 would you stand next to the pipe? What is the formula to work this out? Anwser If a structure is required to meed a safety factor of 10,then that means it is required to survive a load that is 10 times higher
