Introduction:

HRM-505 (40) is a kind of heat trace system specially designed for surface heating. It adopts high-efficiency and low-power trace wires to efficiently provide warmth to the surface and connect with the corresponding surge protective device.

Application Field

The HRM-505 (40) application fields mainly include buildings and facilities in cold industries such as oil & gas, petrochemical projects, offshore platforms, factories, etc. The main purpose of this system is to prevent pipelines, valves and equipment from freezing and thereby protecting them from being damaged.

Other application fields may include chilled water and process water systems, energy transfer systems, temperature control systems, pipe supports and other process systems with similar requirements.

Working Principle

The HRM-505 (40) heat trace system mainly consists of: trace wires, surge protective devices, branch boxes and pipe fittings. The trace wires, which are made of high quality copper, are energized by the power source to transfer heat. The quantity of trace wire depends on the area that needs to be heated, usually one meter long for every 0.1 - 0.2 metres of pipe being heated.

The surge protective device helps to prevent voltage spikes and other issues related to current surges. It also provides protection against arc flash and other types of damage to the trace wire. Furthermore, the branch boxes provide collecting, distributing and initiating function while the pipe fittings are used for connecting the trace wires to the pipes.

The key is the heat transfer technology of the trace wires. It works in the following way: the electric current is passed through the trace wire and produces a resistive heat which is then transferred to the surface of the pipe. The heat dissipates outward through pipe metal conduction, allowing for a slow and uniform temperature increase of the heated pipes.

Conclusion

To sum up, HRM-505 (40) is an effective heat trace system designed for surface heating in different cold industry applications. It is composed of trace wires, surge protective devices, branch boxes and pipe fittings. The trace wires are energized by the power source to transfer heat while the surge protective device is used to prevent current surges. Meanwhile, the branch boxes serve to collect, distribute and initiate while the pipe fittings are used for connecting the trace wires. In conclusion, the HRM-505 (40) heat trace system is an efficient and reliable way to prevent freezing and other damages to pipelines, valves and equipment.
