Upper Dome Wall Turbine & Generator End (160-25)

The document provides design specifications and equations for components that make up an upper dome wall turbine and generator end. It includes 10 parts such as plates, beams, stiffeners and lifting lugs. Equations are given for determining dimensions of each part based on other parameters. Lifting of the assembly must use all lugs simultaneously with D-shackles per the specified standard.

UPPER DOME WALL TURBINE/GENERATOR END (016025A01000):

UdwTeIbD = LdwUEL – UdwLIb


UdwTePH = LdwUEL - UdwTeD
UdwTeH = LdwUEL - UdwTeSD

T.R.:
1. Visual inspection of weld seams to be done as per HW0620099, Classification group
as follows:
a) BS/BK for lifting lugs
b) CS/CK for other items.
2. Non Destructive Examination of welds seams as per HW 0850199, part-10.
3. Painting is to be done as per HE77001.
4. For lifting the assembly, all lifting lugs shall be used simultaneously with D-Shackles
as per AA7248105.
5. The length of I-Beam may be made by welding of two pieces as per detail-I.
6. This indicates critical to quality (CTQ).
