Analysis of fixed installation of common heating pipes

In mechanical heating equipment, some types of heating tubes, such as mold heating tubes, do not require fixings and can be installed directly into the heating hole for heat transfer. Of course, other types of heating tubes, such as single-ended heating tubes, require additional fixings for more stable operation. We all know that fixing and installing heating tubes is a delicate yet essential step to ensure proper and stable operation. Failure to do so can lead to problems such as bending, unstable operation, and localized leaks, which can pose a potential safety hazard. The following explains common types of heating tube installation, fixing, and those that do not require fixings:

1. Mold heating tubes: Common mold heating tubes do not require fixings and are installed directly into the heating hole for heat transfer.

2. Single-ended heating tubes: Single-ended heating tubes come in several types: the standard L-shaped type, the baffle-type type, and the threaded type.

(1) Common single-end heating tubes refer to heating tubes without baffles, threads, or other fixing methods. Their installation methods are: directly installed on the bracket; after drilling holes, copper sheets or other metal sheets are placed on the heating tube to fix it (similar to baffle-type electric heating tubes); some use welding to fix the heating tube.

(2) L-shaped single-end heating tubes can be directly inserted and used in general use environments. They can be installed and fixed according to the installation instructions without special fixing.

(3) Baffle-type heating tubes can be used directly or welded and fixed on the basis of the baffle.

(4) The installation of threaded single-end heating tubes is to screw the heating tube to the part that needs to be fixed with threads. Usually, the threaded type is more commonly used for heating liquids. Of course, if there are strict requirements for sealing, it can also be welded on the original basis.

3. U-shaped heating tubes, flange heating tubes, fin heating tubes U-shaped heating tubes are normally equipped with fasteners. They are usually installed directly with fasteners. If they do not use fasteners, they are usually installed and fixed with brackets or welding.
