Pipe Heating Technical Briefs
Impedance Pipe Heating - Annual Inspection
Impedance pipe heating is one of the most reliable and effective methods to heat pipe and requires little to no maintenance. Because little maintenance is required, we often find that the system is installed and virtually forgotten. Although regular maintenance is not required, it is recommended that an annual inspection be conducted. The Fall of the year is often a good time for this, particularly, for users that have systems operating outdoors in inclement weather and cold temperatures. For those that are finishing up the high temperatures of the summer months, this is a good time to look for any heat related impact on the system. And for those that have systems that are under roof it is just good business and processing practice to conduct an annual inspection to avoid any unforeseen process interruptions.
Codes and Recommended Practices
You are considering your application of heating a fluid in your process, and electric impedance pipe heating looks like just the right fit. Logic suggests that you should be aware of codes and recommended practices to round out your review and provide additional education. So where to turn to?
NEC Control Panel Labeling Requirements
The National Electrical Code (NEC) is a national standard authored and published by the National Fire Protection Agency (NFPA 70). This standard is adopted as regulation in all 50 states and is the benchmark for safe electrical design, installation, and inspection to protect people and property from electrical hazards.
Maintenance and Your Impedance Pipe Heating System
Most heating systems used today have some form of recommended maintenance schedule. Whether it is a complex series of steps that must be done at specific intervals, or simply occasional checking of specified parts, all maintenance schedules have the same basic purpose: Keep the system running. The same is true for an impedance pipe heating system. Impedance pipe heating systems often become that item in the plant that just works. People know that something is heating their pipes, but they don’t always remember what. While this is a great endorsement for impedance pipe heating, the systems do require occasional maintenance to avoid potential downtime.
