ASME V111 Div.1 Appendix 2 has provision for flange design and also bolt size and number based on the allowable bolt stress. I note that in most cases, the required bolt stress is low ( way below the allowable tensile stress allowed for the bolt; basically because of the large number of bolts...
I note that in my plant, carbon steel ( B7 /H2 bolts and nuts are normally used for stainless steel ( 304/316) flanges. I understand that the reason for this is that stainless steel bolts and nuts are harder and the tendency for the nut to loosen is high, hence the use of carbon steel...
ANSI B16.5 furnishes information on Pressure / Temperature ratings of flanges. The pressures given are for NON-SHOCK values.
I have a pipe run (approx. 400 metres long) that occassionally experiences "hammering" due to rapid closing of a valve.
Would appreciate if anyone can tell how I can...
TEMA design has provision to check the actual longitudinal stresses in the shell and tube (periphery of bundle) against allowable stresses (both tensile and compressive).
The code provides a comprehensive guide to determine the allowable longitudinal compressive stress for tubes but mentions...
I would like to know the P group for the high strength low alloy steel plate A 543 Type B Class 1.
Understand that PWHT is not required for this group as per ASME V111 Div. 1
Table UW-12 lists the Weld Type associated with Joint Description and Limitations.
The limitations for Type 3 ( Single welded butt without backing strip)are: Circumferential butt joints only, not over 5/8 " thick and not over 24 in. OD.
Does this mean that the code does not allow a vessel...
