In the use of mechanical heating equipment, some series of heating tubes do not need to be fixed and can be directly installed in the heating hole for heat transfer, such as die heating tubes; of course, there are a series of heating tubes need to be strengthened and fixed in order to make them more stable to work normally, such as single-ended heating tubes. Here we mainly discuss how to fix the heating pipe and how to install it. We all know that fixing and installing heating pipe is a subtle and indispensable link to ensure its normal and stable work. Without this link, there will be problems such as dead break of heating pipe, unstable work, local bare leakage and so on. The common installation, fixing and non-fixing of heating pipes are analyzed as follows:

1. Die heating tube

The common die heating tube does not need to be fixed, and is directly installed in the heating hole for heat transfer.

2. Single-ended heating tube

There are several types of single-end heating tubes, such as L-type single-end heating tubes, baffle type single-end heating tubes and threaded single-end heating tubes.

(1) The common single-ended heating pipe refers to the heating pipe without baffle, thread and other fixing methods. Its installation method is: directly mounted on the bracket; after drilling, fixed on the heating pipe with copper or other metal sheet sleeve (similar to baffle electric heat pipe); and some fixed the heating pipe by welding.

(2) The L-type single-head heating tube can be directly inserted into the use environment. It does not need special fixing to install and fix according to the installation instructions.

(3) The baffle type heating tube can be used directly or fixed by welding on the basis of the baffle.

(4) Installation of threaded single-ended pipe is to screw the threads of heating pipes in the fixed parts. Usually, the threaded type is used for heating liquids. Of course, the strict requirements for sealing can also be guaranteed by welding on the original basis.
