High-Pressure Boiler Inspections

Ensuring safety and reliability for your pressure equipment

about high-pressure boilers

High-pressure boilers are used to heat steam above 15 psi and water pressure that does not go above 160 psig. High-pressure boiler temperatures often exceed 250 degrees Fahrenheit, making them more vulnerable to hazards than low-pressure boilers. A type III steam boiler can produce steam with a higher maximum allowable pressure; up to 350 psig.

High-pressure boilers must be monitored at all times to ensure that the elevated pressures do not cause safety concerns such as overheating. Switches, safety devices, valves, and leaks must be inspected on a frequent basis and any equipment issues or malfunctions must be corrected immediately.

applications for high-pressure boilers

High-pressure boilers are often used in commercial and industrial settings, and generate steam found in industries like dry cleaning, laundromats and power plants.

Different types of high-pressure boilers include:

  • Water-tube boilers, often found in thermal power plants
  • Benson boilers, often used to generate electrical power
  • Superheated steam boiler, which can produce temperatures up to 2,900 degrees Fahrenheit

high-pressure boiler hazards

According to the National Board of Boiler and Pressure Vessel Inspections, even a home hot water tank, if overheated, can send a car flying 14 stories at 85 miles per hour. Larger, jurisdictional boilers and pressure vessels can produce forces of even greater strength and danger.

Both high- and low-pressure boilers can present hazards to employee safety and facility operability. Common boiler hazards include excessive pressure, low water levels, and failure to remove combustible gases from the firebox prior to ignition. These hazards can lead to fire or explosions if not rectified immediately. Routine maintenance is the best way to avoid boiler hazards, though trained inspectors are necessary to ensure compliance and assist with safety measures.

TÜV SÜD safety expertise

TÜV SÜD ARISE is here to assist in your boiler inspection needs. While performing in-service inspections such as Jurisdictional Inspections and Risk Management, TÜV SÜD ARISE inspectors will examine your equipment and processes as they relate to tasks and risks that arise during these site visit. Utilizing this data, the inspector will review your data and recommendations with you to ensure that your high-pressure boilers continue to operate safely and are in compliance with all necessary standards.

ABIIC (ARISE Boiler Inspection and Insurance Company RRG) is licensed to operate in the United States, Canada and Puerto Rico through a network of preferred partners. Inspectors hold National Board Commissions with special endorsements and multiple state licenses for efficiencies in servicing.
