Shell & Tube heat exchanger

specification

Pressure by Flange Temperature

Pressure-temperature rating (for steel pipe flanges and flanged connections) (ANSI B 16-5-1981)

Flange Nominal Pressure Symbol

That means 150 pounds of pressure per square inch.
A unit of pressure, sometimes expressed as PSI.
#150 pounds is equivalent to 10 kgf/cm², so
#150=10K
#300=20K
#600=40K
is being used as
Class 150=10.34 bar/
Class 300 = 20.68 bar (kgf/cm²)

Heat transfer Joint Selection Guide & Plugging Method

Joint between heat pipe and tube plate

Tube puncture check device

You can check the tube hole by disassembling only one cover.
Intuitive leak check device (maintenance cost reduced by 70~80%.)

TUBE pore inspection procedure
① LEAK occurs
② One side cover open (disassembly)
③ Insert TUBE individual tester
④ Check whether TUBE LEAK occurs
      (ALARM warning when LEAK occurs)

TUBE PLUGGING

Tube hole sealing plug

A device capable of disassembling only one cover and sealing the tube on the other side
(Reduction of maintenance cost by 70~80%.)
