Tensile Strength in lbs/inch

Tensile Strength in lbs/inch

Tensile Strength in lbs/inch

(OP)
Hi All :

There are two aluminum pipe pieces having a 1" gap between them and this gap is covered by Ventglas Wrapped around it. Helium gas with a pressure of 35 psi flows through the pipe. My task is to find out what the maximum gap can be without the Ventglas failure.

Now, the strength of ventglas is given as 480lbs/inch in the warp and 360lbs/inch in the filling. What does this means ? What does it mean to have tensile strength in lbs/in rather than psi ?

Thanks,

Kapil,EWI   

RE: Tensile Strength in lbs/inch

It probably means X lbs per unit width (inch) per layer of material.

RE: Tensile Strength in lbs/inch

For fabrics, and some sheet and film products with a fixed or standard thickness, the strength is reported per inch of length.  With fabrics especially, there can be some debate as to what "thickness" to measure, and how repeatably such measurements can be made.   

RE: Tensile Strength in lbs/inch

The specification sheet should tell you if its in lbs/ inch of width or lbs/inch of length or the lbs/inch could also be a biaxial value (longitudinally and circumferentially).

Your best bet is to find out the tensile strength of that material from the supplier which you can use with a suitable factor of safety to determine suitability for a 35 psi gas pressure.
