Question

Accepted Answer

Heat exchanger and pressure vessel are mechanical equipment used in various industries for heat transfer and pressure containment.

Heat exchanger is a device used to transfer heat between two or more fluids of different temperatures.
Pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
The function of heat exchanger is to transfer heat from one fluid to another, while pressure vessel is used to store or transport pressurized fluids.
Mechanical properties such as strength, toughness, and ductility are important for both heat exchanger and pressure vessel. These properties are governed by various codes and standards such as ASME, API, and ASTM.
Material grade and selection is critical for both heat exchanger and pressure vessel. Common materials used include carbon steel, stainless steel, and titanium.
ASME codes and standards provide guidelines for the design, fabrication, and inspection of pressure vessels and heat exchangers.
NDT (non-destructive testing) is used to detect defects or flaws in the material or welds of heat exchangers and pressure vessels.
WPS (welding procedure specification), PQR (procedure qualification record), and WPQ (welding performance qualification) are important documents for welding processes in heat exchangers and pressure vessels.
P number, F number, and A number are used to identify the welding materials and procedures for heat exchangers and pressure vessels.
ITP (inspection and test plan) is a document that outlines the inspection and testing requirements for heat exchangers and pressure vessels.
