When using mechanical heating equipment, some heating tube series do not need to be fixed, and can be directly installed in the heating hole for heat transfer, such as mold heating tubes; Of course, heating tubes and series need to be strengthened to make them work more stably, such as single-head heating tubes. Here, we mainly discuss how to operate the fixing of the heating tube. How to install it? We all know fixation. Installing the heating tube is a delicate and indispensable part of ensuring its normal and stable operation, and the lack of this link will cause the heating tube to collapse deadly. Unstable work. Partial exposed leakage can easily become a hidden danger of accidents and other problems. Common heating tube installation. Fixed and non-fixed analyses are as follows:
1. The mold heating tube commonly used by the mold heating tube does not need to be fixed, and is directly installed in the heating hole for heat transfer.
2. Single head heating tube, single head heating tube, common L-shaped single head heating tube, baffle type single head heating tube, threaded single head heating tube.
(1) Ordinary single-head heating tube refers to the heating tube without baffle, thread and other fixed methods. Installation method: directly installed on the bracket; After drilling, fix the heating tube with copper or other metal sheets (similar to baffle electric heating pipes); Some heating tubes are fixed by welding.
(2). L-shaped single-head heating tube can generally be directly inserted into the use environment, and installed and fixed according to the installation instructions without special fixation.
(3) The baffle heating tube can be used directly or welded and fixed on the basis of the baffle.
(4) The installation of threaded single-head pipe is to screw the heating tube with a thread in the part that needs to be fixed. Generally, more threads are used to heat liquids. Of course, protection with strict requirements for closure can also be welded on the original foundation.
3. U-shaped heating tube. Flange heating tube. Finned heating tube U-shaped heating tubes are usually equipped with fasteners, usually directly mounted fasteners, usually fixed with brackets or welding.
The flange electric heating tube is literally installed and fixed in the way of installing the flange. The installation of flanges can generally be divided into connecting flanges (bolted on) and welding flanges. Generally, in the case of low pressure or sealing requirements are not very high, the connecting flange can be installed and fixed by several bolt holes originally or later processed; At high or low pressure, the flange can be installed and fixed by welding.
It can be said that the basic double-ended heating tube that needs to be installed can be installed with fasteners.
