Fire sprinkler History

In 1812, British inventor Sir William Congreve patented a manual sprinkler system using perforated pipes along the ceiling. When someone noticed a fire, a valve outside the building could be opened to send water through the pipes.It was not until a short time later that, as a result of a large furniture factory that repeatedly burned down, Hiram Stevens Maxim was consulted on how to prevent a recurrence and invented the first automatic fire sprinkler. It would douse the areas that were on fire and report the fire to the fire station. Maxim was unable to sell the idea elsewhere, though when the patent expired, the idea was used.[7][8][clarification needed]

Henry S. Parmalee of New Haven, Connecticut, created and installed the first automatic fire sprinkler system in 1874, using solder that melted in a fire to unplug holes in the otherwise sealed water pipes.He was the president of Mathusek Piano Works, and invented his sprinkler system in response to exorbitantly high insurance rates. Parmelee patented his idea and had great success with it in the U.S., calling his invention the “automatic fire extinguisher”. He then traveled to Europe to demonstrate his method to stop a building fire before total destruction.

Parmelee’s invention did not get as much attention as he had planned, as most people could not afford to install a sprinkler system. Once he realized this, he turned his efforts to educating insurance companies about his system. He explained that the sprinkler system would reduce the loss ratio, and thus save money for the insurance companies. He knew that he could never succeed in obtaining contracts from the business owners to install his system unless he could ensure for them a reasonable return in the form of reduced premiums.

In this connection, he was able to enlist the interest of two men, who both had connections in the insurance industry. The first of was Major Hesketh, a cotton spinner in a large business in Bolton who was also chairman of the Bolton Cotton Trades Mutual Insurance Company. The directors of this company and its secretary, Peter Kevan, took an interest in Parmelee’s early experiments. Hesketh got Parmelee his first order for sprinkler installations in the cotton spinning mills of John Stones & Company, at Astley Bridge, Bolton. This was followed soon afterwards by an order from the Alexandra Mills, owned by John Butler of the same town.

An 1897 Grinnell automatic sprinkler advertisement

Although Parmelee got two sales through its efforts, the Bolton Cotton Trades Mutual Insurance Company was not a very big company outside of its local area. Parmelee needed a wider influence. He found this influence in James North Lane, the manager of the Mutual Fire Insurance Corporation of Manchester. This company was founded in 1870 by the Textile Manufacturers’ Associations of Lancashire and Yorkshire as a protest against high insurance rates. They had a policy of encouraging risk management and more particularly the use of the most up-to-date and scientific apparatus for extinguishing fires. Even though he put tremendous effort and time into educating the masses on his sprinkler system, by 1883 only about 10 factories were protected by the Parmelee sprinkler.

Back in the U.S., Frederick Grinnell, who was manufacturing the Parmelee sprinkler, designed the more effective Grinnell sprinkler. He increased sensitivity by removing the fusible joint from all contact with the water, and, by seating a valve in the center of a flexible diaphragm, he relieved the low-fusing soldered joint of the strain of water pressure. By this means, the valve seat was forced against the valve by the water pressure, producing a self-closing action. The greater the water pressure, the tighter the valve. The flexible diaphragm had a further and more important function. It caused the valve and its seat to move outwards simultaneously until the solder joint was completely severed. Grinnell got a patent for his version of the sprinkler system.He also took his invention to Europe, where it was a much bigger success than the Parmelee version. Eventually, the Parmelee system was withdrawn, opening the path for Grinnell and his invention.

What are the potential limitations or drawbacks of using galvanized grooved fittings?

While galvanized grooved fittings offer effective corrosion resistance and are widely used in various piping systems, there are potential limitations and drawbacks associated with their use. It’s important to consider these factors when deciding on the appropriate fittings for a specific application.

Here are some potential limitations:

  1. Limited Corrosion Resistance in Certain Environments: While galvanized coatings provide good corrosion resistance in many environments, they may not be suitable for highly corrosive or aggressive environments. In such conditions, where exposure to chemicals or severe corrosion is a concern, alternative materials or coatings with enhanced corrosion resistance may be more appropriate.
  2. Zinc Coating Vulnerability to Certain Substances: The zinc coating on galvanized fittings may be vulnerable to specific substances, such as certain acids or alkalis, which can accelerate corrosion. It’s essential to assess the compatibility of galvanized fittings with the specific fluids or substances they will come into contact with in the piping system.
  3. Potential for Zinc Whisker Formation: Over time, galvanized coatings may develop zinc whiskers—tiny, crystalline structures that can form on the surface. While not always a significant issue, zinc whiskers could potentially pose challenges in certain applications, such as data centers, where they may cause electrical shorts in sensitive equipment.
  4. Impact on Welding: Galvanized coatings can present challenges if welding is required for modifications or repairs. Welding galvanized material can produce harmful fumes, and the zinc coating may need to be removed in the welding area, affecting the protective layer.
  5. Initial Cost: Galvanized grooved fittings may have a higher initial cost compared to some other materials. While the corrosion resistance is an advantage, galvanized grooved fittings it’s important to consider the overall project budget and whether the additional cost is justified based on the specific requirements of the application.
  6. Environmental Concerns with Zinc: The production and disposal of galvanized materials involve zinc, which can raise environmental concerns. Zinc is a metal that, if released into the environment, can have ecological impacts. Consideration of environmental sustainability and disposal practices is important.
  7. Thermal Limitations: Galvanized coatings may experience changes in appearance or performance at elevated temperatures. It’s important to assess the operating temperature range of the system and ensure that galvanized fittings are suitable for the intended temperature conditions.
  8. Complexity in Field Modifications: Making field modifications or alterations to galvanized grooved fittings can be more complex compared to certain other materials. Welding galvanized material requires proper safety measures, and the removal of the zinc coating may be necessary.
  9. Aesthetic Considerations: The appearance of galvanized fittings may change over time due to factors like exposure to weather conditions. In applications where aesthetics are a concern, it’s important to consider the potential impact on the visual appeal of the system.

While galvanized grooved fittings are widely used and offer effective corrosion protection, these limitations highlight the importance of carefully evaluating the specific requirements and conditions of the piping system. In some cases, alternative materials or coatings may be more suitable based on the unique challenges posed by the operating environment and the fluids being transported.
