Whether it's a natural gas pipe, hot or cold pipe, temperature consistency is crucial. Adding industrial pipe insulation delivers better process control by maintaining the temperature from pipe entry to exit. This can lead to greater operating efficiencies and reduced energy loss — which, in turn, can lead to reduced operating costs.
