Hi,
I need to know the formula for calculating deflection of corrugated (concentrically) diaphragms under application of pressure. If I am not mistaken, this formula is obtained by modifying the deflection formula for flat diaphragms, wherein the effect of corrugation is taken care by...
Hi,
I need to know the bursting pressure of both laminated glass (100mmOD,3mm thk) and Toughened glass (100mmOD,3mm thk).
Do I need to do the test myself and find out or would this information be available with glass manufacturers / reference books etc.
Thanks in advance.

We are facing failure problems of a springs made up of SS316L material ( 1.0 mm wire diamter, 6.3mm outer diamter, 9.5mm length)which are used in our special pipe fittings. The spring is exposed to the...
Hi,
We are facing failure problems of a springs made up of SS316L material ( 1.0 mm wire diamter, 6.3mm outer diamter, 9.5mm length)which are used in our special pipe fittings. The spring is exposed to the fluid and supposed to work in 'compressed condition'. It is clear from our observations...
Hi,
I am planning to use a ceramic component (Alumina 99.7%) for one of my projects. I need to test the following of the same :-
(1) Composition :- Though the supplier claims that the alumina content is 99.7%, I would like to know the best method to test the same.
(2) Hardness (Wear...
Hello,

Hello,
I am in process of designing a flanged meter housing of Class 1500 rating at design temperature of 464°F in CF3M material. The flanges to be used are of material A182 F316L. The inner radius of the housing is 39 mm ( 1.5354”). I have followed following procedure to determine the minimum...
In one of the applications, we need to fit stainless steel (SS304 grade)threaded caps on a transmitter housing made up of aluminium alloy (GD AlZn10Si8Mg). The transmitter housing is meant for housing electronic modules and expected to withstand temp upto 75 degC. The housing is not expected to...
Hi,
We need to coat the stainless steel springs with teflon (25-30 microns)in order to increase the corrosion resistance. The spring wire diamter is 0.55mm and its un-compressed length is 9.5mm. We tried a few times but failed to achieve the continuous teflon coating all round the spring wire...
