In many industrial applications, heating cables are a common solution for efficient and reliable heat distribution on pipes. Whether metal or plastic pipes, heating cables can be effectively installed and insulated to meet different needs.
The installation process includes the following steps:
Pipe surface preparation: Before installing heating cables, make sure the pipe surface is dry, clean, and free of any obstructions. This can be done by using the appropriate cleaner and brush. It is also important to ensure that the pipe surface is flat so that the heating cable can fit snugly.
Heating cable selection: Select the appropriate heating cable type according to your needs. There are two common types of heating cables: self-regulating and constant wattage. Self-regulating heating cables automatically adjust to ambient temperature, while constant-power heating cables provide a constant heat output. Select the appropriate heating cable based on your specific application needs.
Heating Cable Installation: Wrap the heating cable around the pipe, making sure to maintain proper overlap between each turn. Use specially designed heating cable clamps to secure the cable and ensure tight contact between the cable and the pipe surface for optimal heat conduction. During installation, ensure that the cable is not stretched or twisted, which could affect its performance.
The purpose of insulation is to prevent heat from escaping and ensure that heat is evenly distributed across the surface of the pipe. The following are common insulation treatments:
Insulation material selection: Choose high-quality insulation materials such as polyethylene foam or silicone sleeves. These materials have good insulation properties and high temperature resistance, which can effectively insulate and protect heating cables.
Insulation installation: Place the insulation around the heating cable and make sure the insulation completely wraps the cable. Use specially designed insulating sleeves and ensure there are no gaps between the sleeves and the heating cable to avoid heat leakage.
For plastic pipes, heating cables are also suitable. However, there are a few things to note during installation:
Make sure there is adequate insulation between the heating cable and the plastic pipe. This can be insulated using high-temperature resistant insulation or metal foil to prevent damage to the plastic pipe from the heating cable.
Choose the appropriate type of heating cable to avoid excessive temperatures on the plastic pipe. Self-regulating heating cables are a good choice because they automatically adjust their power output based on the ambient temperature to maintain the right temperature.
If you don’t know which heating cable to choose, try Jiahong.
Jiahong heating wire, also known as heating wire and heating tape, is designed to provide thermal compensation solutions for a variety of applications. It has continuous exposure (maintenance) capabilities up to 225°F (110°C) and intermittent exposure capabilities up to 392°F (200°C or 250 psi steam).
If you need to maintain containers, vessels or pipes between 65°C and approximately 100°C. 110°C, then this heating cable is your best choice.
Currently, Jiahong HTP heating cables have four different models, targeting the entire European and American markets:
5 watts per foot (17w/m),
10 watts per foot (33w/m),
15 W/ft (45 W/m),
20 watts per foot (66 watts/meter).
To summarize, efficiently installed and insulated heating cables allow for heat distribution on pipes. By correctly selecting and installing heating cables and using appropriate insulation materials, you can ensure even temperature distribution on the pipe surface and increase the energy efficiency and reliability of the system. Whether for metal or plastic pipes, heating cables are a reliable and economical solution for a variety of industrial applications.
