ST tube in tube heat exchangers find their application where fluids of high viscosity, density or high fiber or solid particle contamination are subjected to heat treatment, e.g. at waste water treatment plants.

The presence of different types of mechanical contamination causes their sedimentation on the walls, which blocks the flows in the exchanger. Large diameter of the ST exchanger tubes ensures their free flow and the dismountable design allows for mechanical cleaning of the heat exchange surface.

Stainless steel make ensures corrosion resistance and the simple design ensures long-term failure-free operation.

Features

Dismountable design

allows for mechanical cleaning
Option to increase heat exchange surface

by adding further sections, the number of which depends on the media type and working parameters
Stainless steel make

ensures corrosion resistance
Broad range

with various nominal diameters and modules with 3 meters and 6 meters in length ensures flexibility in system design

Design

Section

The exchanger consists of appropriate number of sections connected in series with knee tubes and set on a frame.
Frame
Knee tube
Thermal elongation compensator

For the tubes is used in case of significant temperature difference between product side and shell side.
Connection

Tube in tube

The single section of the ST exchanger consists of two tubes with different nominal diameters. The tube with smaller diameter (product side) is installed inside the tube with the larger diameter (shell side).
