Four main heat treatment methods in carbon and alloy steel pipe industry. The heat treatment processes for steel pipe includes normalizing, annealing, tempering, quenching and other process. Normalizing. Heating the steel pipe above the critical temperature, and cooled in the air.Heat Pipes for Thermal Management | ACTEffective thermal conductivities can approach 10,000 to 100,000 W/m K for long heat pipes, in comparison with roughly 400 W/m K for copper. The choice of material varies depending on the application and has led to pairings such as potassium with stainless steel, water with copper, and ammonia with aluminum, steel, and nickel.HVACR Equipment/Components - Air Conditioning, Heating Heat pipe exchangers are similar to cooling or heating coils but without external connection. They are completely passive devices without any moving parts. Heat pipes tubes and fins are commonly made of aluminum or copper. To increase heat transfer, all tubes have an inner wick structure. Below is a summary of how heat pipes work (Figure 9).
VRF heat pump systems permit heating or cooling in all of the indoor units but NOT simultaneous heating and cooling. When the indoor units are in the cooling mode, they act as evaporators; when they are in the heating mode, they act as condensers. These are also known as two-pipe systems. Cooling Type VRF System Figure (Source: Fujitsu)HEAT TRACING PRODUCTS - Chromalox, Inc.insulation, a weather barrier and gaps between each layer. If the pipe and its contents are warmer than the surrounding environment, heat will be transferred from the pipe to the air. If enough heat is transferred out of the pipe, the pipe contents may thicken or solidify resulting in damage to pipes or pumping equipment.
