Dear all,
Please share detailed calculations for tubesheet of DEU exchanger based on AD Markblatter code.
This is required to understand the philosophy as i am not using this code frequently.

Dear Sir,
Para 207-3.5 of ASME PCC 2-2018 states that "Plug/slot welds may be designed to take up to 30% of the patch plate load.".
Please explain how "Patch plate load" shall be calculated as i could not find the formula to determine patch plate load in ASME PCC 2.

Dear All,
We have an Ammonia storage tank designed on API 620 R. Material of construction for roof, shell and bottom is ASTM A 573 Cl.1 (CS). Min metal design temperature is minus (-)45 deg C and operating temperature is minus (-)33 deg C.
Inspection of roof is done and it is badly corroded...
A tank (designed on API 620 Appendix R) has roof with supporting structure as shown in attachment.
In appendix F of API 620, there is sample calculation of self supporting roof but no calculation available for roof with supporting structure.
Please share reference/guidelines of calculation to be...
Dear Sir,
1" NPT threaded carbon steel elbows (3000#) and piping are installed at downstream of control valve drain. Service is hot compressed air (P = 7.5 bar and Temp = 350 deg C).
Control valve is passing.
Now it is required to install NPT valve at open end (drain end) of piping to contain...
Dear All,
We require A-179 tubes (OD 19.05 - 2.11mm MWT) to be hydrostatically tested at 250 bar (25MPa) as test pressure of tube side of heat exchanger is 250bar.
But manufacturer says that he shall perform hydrostatic test at 70 bar (7MPa).
Per Table 7 (para 23.2) of SA-450, Hydrostatic test...
Dear All,
Inner diameter of heat exchanger shell is 438mm and diameter of baffle is not specified on the drawing.
Therefore clearance between shell and transverse baffle can not calculate. Moreover, 438 mm Shell ID is neither in range of 152-432 nor in 457-991 of below Table RCB-4.3 of TEMA.

Please clarify the following:
Nominal wall thickness of pipes specified in ASME B31G is nominal wall thickness calculated by B31.8 or installed nominal thickness in field.
Please reply with references.
02 1"-3000# half couplings are required to be installed on 4"-3.05mm thk pipe made of 316L. Design Pressure = 1kg/cm2g and Design Temp = 166 deg C
02 offtakes shall be 90 degree apart on circumference (same plane) of pipe.
I understand that no additional reinforcement is required as half...
Dear Sir,
Problem:
A plate heat exchanger (PHE) is placed at middle platform of multistory steel structure. The platform over PHE platform can not be removed.
Solution
I want to lift PHE by using upper platform. Sketch is attached. Angle shown in sketch shall be more than 45 deg.
Concern
Is...
Problem Description:
A plate heat exchanger (PHE)(dimensions are length 3150 mm x width 850 mm x height 2540 mm) is placed at 2nd platform of steel structure. Steel structure consists of 04 platforms and equipment are placed on all the platforms.
Now we have to move out the PHE from 2nd...
