The following shall be considered in piping arrangement around Air Fin Cooler (AFC)
1. Arrangement
a. Determination of Arrangement
-Air-fin cooler shall principally be installed near related equipment
-Space shall be secured between column or structure
-Layout for stairs, ladder, etc. to access air-fin cooler shall be studied confirming to customer’s specification at the planning of Plot Plan
b. Determination of Installation
-Air-fin cooler installation height shall be determined by adding the minimum (shortest) height between the air-fin cooler and the receiver to the receiver
installation height.
-When located on pipe rack, installation height shall be determined considering above mentioned, height and number of stages of pipe rack
2. Structure Planning
-The legs of air-fin cooler shall be aligned as much as possible, to the columns of the structure.
-For air-fin coolers plugging there tubes, the use of mobile crane shall be considered.
-For piping support, principally support shall independently be attached to the structure.
-Platform planning for maintenance
3. Piping Plan
-Plan for Manifold
a. Types of manifold
-U-type
-MU-type
-T-type
b. Selection of Manifold
-Piping Plan
4. Design Work Flow
-Advance Check
-Preparation of Conceptual Drawing
-Preparation of Piping Arrangement
-Preparation of Auxiliary Piping Arrangement of Air Fin Cooler such as drain/vent
a. STEP 1
-Checking the required documents
-Understanding the contents of basic documents
-Checking of Air Fin Cooler itself and relevant items
b. STEP 2
-Preparation of conceptual routing drawing
-Studying for the necessity of operation platform and pipe support
-Studying of basic piping plan
c. STEP 3
-Planning of AFC positioning
-Planning for Steel Structure
-Preparation for detailed piping arrangement
