Скачать или смотреть tube bundle all part of heat exchanger #

changer refers to a packed arrangement of tubes within a shell. These tubes facilitate heat transfer between two fluids, with one fluid flowing through the tubes and the other flowing around them within the shell. The tube bundle, along with the shell, tube sheets, and other components, forms a complete shell-and-tube heat exchanger. 

Here's a breakdown of the key components:

Tubes:

These are the individual pipes arranged in a bundle, often made of materials like copper, stainless steel, or titanium for their high thermal conductivity. 

Tube Bundle:

This is the overall structure of the tubes, typically designed with a specific arrangement (e.g., straight, U-shaped) to optimize heat transfer. 

Shell:

A cylindrical enclosure that houses the tube bundle and contains the second fluid, which is typically heated or cooled by the fluid flowing through the tubes. 

Tube Sheets:

These are plates at the ends of the tube bundle that support the tubes and ensure proper sealing. 

Baffles:

These are plates inside the shell that direct the fluid flow and increase turbulence, enhancing heat transfer. 

1. Pre inspection - check all the components gasket area tube bundle

2. Post inspection - All components should be clean
Tube bundle should be clean

3. NDT - tube budle - RFET
4. NDT - Shell & Components - MPI & DPT of T- joints
5. Thckness survey of all Shell and components

6. Hydrotest three steps in Floating head Exchanger
1- Shell side hydrotest -Cheak all the tubes if leakage water comes from tube side

2- Tube test -check the shell nozzles if any leakage water comes from shell outlet nozzle

3- Final test - check all the Flanges areas like channel head flanges,channel cover flanges,Dished flanges if leak is there then water comes from the gasket area

7 check the pressure gauge it should be 1.5 time to 4 times of the test pressure two gauges are required for hydrotest inlet and outlet both are same if pressure is 20 then minimum 35 kg to maximum 80 kgcm/2 both gauge are same
