Dears,
I wish to know following matters on the usage of Longitudinal Baffles in F-Type Shells.
1. Does HTRI give seal leakage analysis report for Longitudinal Baffles in F-Shells in case of single phase as well as two phase flow on Shell side.
2. May I know the recommended guide lines on the...

Request clarifications
For ASME SEC VIII Div 1, is it permissible to form CS & LAS Cones from Plate by Petal Construction.
1. Normally I understand that the Cones are rolled in segments (without thinning) and joined together with staggered L-Seams.
2. The term Petal constriction will...

ASME Sec VIII Div 1 provides rues for Extreme Fibre Elongation for formed Shells.
1. When Plates for Shells are cold formed by rolling along the longitudinal direction of plate rolling (ie. along the grain orientation), this phenomenon is quite understandable. But if the Plate is rolled...

1. In the Design of Horizontal / Vertical Vessels and Heat Exchangers is it required to consider Nozzles loads for the design of supports / Brackets. This will tend to increase Vessel Thickness / Anchor Bolt Diameter / Foundation loads etc.
2. For Heat Exchangers, TEMA-10 Has certain...
In a particular Cooling application of DM Water & Sea Water, the temperature profiles with pinch are:
Cold Fluid (Sea Water) in / out = 40 C / 50 C
Hot Fluid (DM Water) in / out = 50 C / 40 C
1. Does a Shell & Tube Heat Exchanger of TEMA type E/ H shells suitable
2. Does a Plate Heat Exchanger...

1. For Tube sheet Design to ASME Sec VIII Div 1 UHX, Length of Tube Expansion in Tube Sheet Holes (ltx) is an input parameter. This influences the Thickness requirement of Tube Sheet. As I understand, we have basically two types of Tube To Tube sheet joints:
a) Expanded Joints (with or...
Dears,
Need following clarifications
1. For Tube sheets of Stainless Steel materials, ASME SEC II D gives two sets of allowable stresses (Higher & Lower). As per Note G5 Table 1A, higher allowable stress to be used for gasketed joints where a distortion can cause leakage.
2. I the design of...
Dears,
Kindly advise me on following:
1.Design problem: Heat Exchanger Designed to ASME Sec VIII Div 1 + TEMA-R, having Flat Bolted Channel Cover with an opening in it
2.Applicable rules are found to be UG 34 together with UG 39.
3. It is observed that thickness required per UG-34 fails when...

Our client asks us to Check Standard Nozzle Flange with external loads independently to ASME Sec VIII Div App-2. When we check the design by PV Elite for the Flange to APP-2, it calculates Peq from FA and MC and ML (Peq = Design Pressure + (4*FA/PI.G^2) + (16 ME/ Pi. G^3) where ME = (Mc^2...

Understand that for Titanium Fabrication as for Heat Exchangers, a clean room (Dust free) is required at th Pressure Vessel workshop especially to warn off flying Iron particles in the air due to nearby metal Cutting / Grinding and other operation.
1. What are the norms for such enclosure...
When designing Shell & Tube Heat Exchangers as per HTRI Xist, is it required to enhance the Tube thickness at input to ensure pressure drop limitation when Tubes are procured with
a) Minimum wall tolerance of +20% -0
b) Average wall tolerance of + - 1o%
What input thickness is to be used.

1. I wish to know the acceptance criteria for Shell and Bundle Entrance & Exit areas calculated by TEMA-10 Section 10 RGP-RCB-4.6.2.
2. Example calculations including acceptance values will be of great reference.
Thank you in advance.

What are Round Condensers for Power Plants.
Are they different from the Condensers of the type given in HEI standards.
A schematic sketch of Round Condenser will help to understand the same.

For Div 2 application what Carbon Steel Specification is to be used for Heat Exchanger Seamless Tubes.
I observed that Sec II D Table 1A lists SA 179 & SA 192 for Div 1 application, where as Table 5A does not list these for Div 2. What are the reasons and recommendations?
1. In an Industrial situation, for a typical High temperature Reactor Design, we have the following critical conditions:
1.1 Design Temperature = 500 C
1.2 Working Temperature = 451 C
1.2 Design Life = 20 Years.
1.3 Materials of Construction of Vessel = Low Alloy Steel Base metal + Corrosion...
I wish to know whether PV Elite has a program to issue components design under Codecalc (CC) for PV and HEX to ASME Sec VIII Div 2. It is very much in need.
When there is a temperature cross in a Shell & Tube Heat Exchanger, we design Shells in series or use F-Shell.
May I know the limitations of Shell & Tube Heat Exchangers F Type shells with Longitudinal Baffles.
Are longitudinal baffles recommended for high shell side pressures.
I am in need of guide lines on following.
1. Is design of welding neck flanges with full face gasket covered in ASME Sec VIII Div 1 or Div 2.
2. If not covered in the codes, how to design same.
3. Is such design acceptable for code construction.
