What is the purpose of tube end testing for floating head heat exchangers?
Thread Content
What is the purpose of testing the tube ends in floating-head heat exchangers? Additionally, what do tube ends refer to?
The tube head is the welding joint where the heat exchange tube is welded to the tube sheet. The purpose of pressure testing is to check the quality of the pipe end welding joints.
The purpose of pressure testing is to verify the sealing performance of the weld joints between the heat exchange tubes and the tube sheet.
Is the poster referring to a floating head? They are on both sides of the tube end
The tube head refers to the part where the heat exchange tube is connected to the tube sheet. Due to the characteristics of floating-head heat exchangers, it is not possible to use shell-side pressure testing to check the welding quality and sealing at the floating-head end; therefore, special equipment must be used to inspect this area.
