Hot water piping in boilers pertains to the system of pipes that conveys heated water from a boiler to different areas within a building or facility. This hot water is commonly utilized for space heating, domestic hot water supply, or process heating.
Both stainless steel and mild steel can be utilized for hot line applications. The choice of piping material is influenced by the desired longevity of the piping. While steel pipes are generally more expensive, they offer a longer lifespan compared to mild steel pipes, which are more affordable but have a shorter durability in comparison to steel pipes.
