Ammonia Valves - How To Install, Handle & Operate Valves Safely

Ammonia, in its various amounts of dilution, is a disastrous element. The anhydrous ammonia is classified as a toxic and dangerous gas for the environment. It can form explosive mixtures upon reaction with air (16-25%) as it is a flammable gas (autoignition temperature 651 °C). Ammonia reacts violently with halogens too. Due to such explosive nature of the gas, it is important to be very cautious about its storage & handling.

Handling Ammonia

• You must be certified to work with anhydrous ammonia.
• While working with ammonia, you must importantly wear goggles, gloves and breathing apparatus.
• It is vital to drain all tanks, piping, and hoses of anhydrous ammonia completely before installing, removing, or repairing any equipment.
• Have sufficient amount of water before working with ammonia.

Installing & Operating Ammonia Valves

• Ensure that the valve is turned off before installation & place it in a direction in relation to the flow.
• Apply a pipe thread sealant to a male pipe thread to be installed into a valve.
• Install the valve into a pipe or hose assembly and tighten it using a wrench.
• Before operating a valve, ensure that it is attached to appropriate piping & also that an appropriate valve is attached to the outside of the valve.
• Turn off any downstream valve that is open to prevent ammonia from spraying into the air.
• Never open the valve partially.
• Never leave the valve open unattended. It must be open only while in use.

Maintaining Ammonia Valves

• Check the valves regularly for any leaks.
• If you observe leaks, try to tighten the valve. If it doesn’t stop, replace with a new valve.
• Constantly observe if any of the valves have worn out and consider replacing the worn out valves at the earliest.

Fusible Plugs - An Essential Safety Valve & Pressure Relief Device

Fusible plugs are used to keep the temperature of the fusible metal below its melting point. The fuse plugs operate as a safety valve when abnormal or dangerous temperatures build up in a closed vessel. They have low melting points, making them useful to be used in mechanisms that require high-temperature settings. Due to this characteristic, they are used on some boilers to provide added protection against low water level.

This fluid coupling overheating protection device is a needed component in your industrial set up. Constructed of bronze or brass, the pipe plug has a tapered hole, which is drilled through the length of the valve. It has an even tapered from end to end that is filled with a low melting alloy – mostly consisting of tin. Fusible plugs are of two types:

FIRE-ACTUATED: The boiler plug is an alloy of tin, copper & lead and has a melting point of 6° to 7°. One end of the plug is attached to the tire/hot gases while the other is in contact with water. In case the water level drops below the plug, tin melts and blows out. It will produce a whistling noise to warn the operator that it’s time to replace the plug.

STEAM-ACTUATED: The plug is installed on the end of the pipe outside the drum. The other end of the plug is kept at the lowest permissible water level in the steam drum. The metal in the plug melts at a temperature below that of the steam in the boiler. The water around the plug is at a cooler temperature than that in the boiler as long as the pipe end is below water level. When the water level drops below the open end of the pipe, steam heats the fuse plug, which melts down the tin letting out a warning to the operator.

It is important to maintain the fusible plugs and replace them every year. Do not try to refill the old casings with new tin alloy as this would only harm the material and lead to a dangerous effect. It is advised to always use a new plug.

You have arrived at the right place to search for a new fusible plug. At JTC Valve Sales,  https://www.jtcvalvesales.com/blog we stock only high-quality valves and their accessories to maintain the specific standards demanded by the industries. You can get in touch with us at 440-346-1259 to discuss the specifications before you purchase.

What Type of Hose Can Be Used for CO2 Transfer – The Evolution

In the earlier times, the hoses manufactured with rubber were designed for hydraulic uses. However, when these hoses were exposed to carbon dioxide, they could not resist deterioration. On inspecting the reason, it was found that there were reinforcing braids and fittings made from carbon steel, which is susceptible to corrosion from the carbonic acid that is formed from a combination of CO2 and moisture. This resulted in developing cracks in the hoses due to cold temperatures associated with the CO2 transfer.

 

Some time later, stainless steel hoses were introduced. This attempt was better than the previous ones in remaining flexible in the cold but lead to much harder and heavier hoses. Additionally, the corrugation inside the metal hose could trap solid CO2 ice, interrupting the CO2 transfer.

The latest innovation was Polar Hoses, which were specifically built for bulk CO2 transfer. The elastomer used in the manufacturing of these hoses was found to be perfectly compatible with CO2 and low temperatures. This CO2 hose has stainless steel braids and corrosive fittings that offer them durability and strength. Polar hoses are light-weight, flexible and strong pipes, proving to be the best for bulk CO2 transfer.

 

JTC Valve Sales houses polar hoses that are tested to 675 psig. We offer polar hoses that have corrosion resistant brass end fitting with aluminium crimp collar. All our assemblies carry a 5 to 1 safety factor. We are trusted for our quality products and strict adherence to industry standards.
