Boiler Servicing Procedure for Heating Engineers and
Test the Emergency Control Valve (ECV) – sometimes some, older installations may have a missing or corroded valve. This should be treated as an emergency. Legislation states that an ECV wheel or lever should be securely fitted.It also advises that a lever should be parallel to the direction or axis of the gas pipe in the open position so make it clear if the valve is turned on or off.

There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.

Bank Tube Failures in Bi-drum Boilers - IDC-Online
2019-2-4 · Reasons for bank tube failure The main reason for bank tube failure due to expanded joint failure is inadequate expansion. Many times it is very difficult to measure each tube ID for checking the percentage thinning, hence it is a practice to measure a few tubes in every 100 or 200 tubes and fix the expander torque to get the required thinning.
Wilson Tube Expanders are designed to work with tubes in a wide range of sizes. Our mandrel expanders help you roll tubes in difficult to reach areas while our power-driven linsen expanders work well in short bends, U-turns, copper, brass, aluminum, or thin steel tubing.
