Structure composition and installation preparation of tubular heat exchanger

- Apr 16, 2018-

Whether in high temperature, low temperature or high pressure, low pressure environmental conditions, tubular heat exchanger can be used.

As one of the most widely used heat exchangers in chemical production, tubular heat exchangers have simple structure and high heat transfer efficiency, which are praised by users. Let's take a look at the construction of tubular heat exchangers. Its main structure is in a cylindrical shell body, set up a number of parallel tubes composed of tube bundles. The ends of the shell and the end caps are provided with flanges, and the end caps are connected with the housing by bolts.


The Russian shell and the end cover are respectively provided with two kinds of medium inlet and outlet small flange to facilitate the corresponding pipeline connection. In order to give full play to the superiority of tubular heat exchanger, we must complete the installation work reasonably. Of course, before you install, you need to be prepared.


Fully prepare the heat exchanger before installation, can make the installation work smoothly, meet the installation of technical indicators to ensure the installation quality. First of all, to do a good job in the on-site preparation of construction, at this time, according to the site layout of the construction plan, the scene of the other aspects of the actual exploration, measurement to determine the transport route, parking position, unloading location and surrounding environment to affect the transport and installation of equipment, coordination with relevant parties to Dredge the road of transportation, we must ensure that the road is flat and solid, so that the vehicle can be smoothly passed, safe pipe-type heat exchanger transported to the scene.


In addition, installation width should meet installation requirements. Next also to the tube-type heat exchanger for inspection and acceptance. Mainly for the equipment model, quality, geometric size, nozzle orientation, technical characteristics, such as inspection. At the same time also check whether the tube-type heat exchanger is damaged, missing pieces (including iron, bolts, gaskets, accessories, etc.).

Do a good job of checking and recording.
