This is fastener standard for bolts Grade 8.8 means, Approx. 800 Mpa tensile strength and 640 MPa yield strength (you will arrive at the YS by multiplying both the numbers times 10. That is 8x8x10=640) Similarly, 10.9 means approx.1000Mpa TS and 9...
1) when & why expansion is necessary? Expansion is necessary in all cases because the tube hole in the tube sheet is slightly higher than the tube OD. So if we do not expand it will cause crevice and ultimately tends to leakage...

1.what are all the Quality checkpoints while welding with SS? Welding of SS special compared to CS. Do not mix up CS with SS welding. Avoid using the same hand gloves, grinding wheel, tongs or even the same work area used for CS to avoid Carbon m...
Ultrasonic phased arrays use a multiple element probe whereby the output pulse from each element is time delayed in such a way so as produce constructive interference at a specific angle and a specific depth. These time delays can be incremented ...
