I'm designing now a heating coil of SA-333 6 material that works at 375°C. By checking ASME BPVC II-D(M); Table A1 Note T-1, Allowable stresses for temperatures of 370°C and above are values obtained from time–dependent properties. The coil will work under this conditions for 24 hours every...
It is agreed that Roark's formula (7th edition) Table 9.2 Ref. No. 1 is not applicable for base block check in case of single tailing lug. Ref. No. 20 is the one that is commonly used by design software packages.
But, in case of 2 tailing lugs, what should be the case? Ref. No. 4 is used by...
I have a heating coil of 3 m length. It is mainly 2 pipes but bended into 8 flows with only 4 ends welded to the cover of the heating coil insertion nozzle.
In order to provide the necessary moment of inertia and to enhance the rigidity of the bundle, I have utilized a longitudinal stiffener...
I'm currently looking for a software which can perform the design calculation for the drums fabricated per Section I. I'm still surprised that PVElite and COMPRESS doesn't provide this service.
Looking for your helpful replies.

I have a littel confusion with Compress concept with estimating the joint efficiency due to RT applied to Cat-B welds in 2:1 Ellip Heads and Cylinders.
Suppose;
Case 1: Head is seamless, RT for Circumferential weld between head and shell is Spot, and Shell is also Spot. What should be the E...
Our client insists to have a socket weld coupling as a temperature gauge nozzle in NPS 1 or less Size. My question is; Does any one have a past experience with this nozzle end configuration? How was the hydrotest conducted? Is there any code reference to allow opening and welding these...
Dear All;
I have successfully designed a Jet-A SS double walled pressure vessel and hydrotested. The internal vessel is the main vessel. The outside vessel is for leak detection as well as will work as a standby vessel in case of the failure of the internal vessel till the maintenance or...
