Titanium Fabricated Shell And Tube Heat Exchanger

Description

Shell and tube heat exchanger is a kind of working medium from the head of the inlet pipe into the heat transfer tube, the process can achieve one tube, two tube and four tube structure according to the process requirements; The other working medium enters into the shell by the inlet pipe at one end of the shell and distributes evenly outside the heat transfer tube. As a heat transfer element - heat exchange tube, according to the process requirements of brass tube, copper fin tube and steel tube, so as to ensure that different physical properties, different temperatures of the working medium in the heat exchanger to achieve the heat exchange, to achieve the purpose of cooling or heating.

Parameter

Features:

The shell-and-tube heat exchanger has a simple, compact structure and low fluid resistance, and can be used to manufacture large-scale equipment, but its pressure and temperature resistance is lower than that of the block-hole type. Condenser is better, and it can also be used as general heating equipment after being processed by special technology. Usually a series of baffles perpendicular to the tube bundle are installed outside the tube. At the same time, the connection between the tube and the tube sheet and the outer shell is rigid, and there are two different temperature fluids inside and outside the tube.

Cooler cleaning:

1. After the cooler works for a long time, the surface of the tube wall is gradually formed with dirt, which affects the heat exchange effect. At this time, it should be cleaned, and the cleaning cycle can be determined in about one year according to the cleanliness of oil and water.

2. When cleaning, kerosene (gasoline, trichloroethylene) can be used to wash the tube bundle, end cover and shell, etc. until they have a metallic luster. After reassembly, perform a pressure test of 1.25 times the design pressure without leakage.
