What You'll Learn

Drip pan elbows are used on steam service
The Kunkle 299-H, 2" drip pan elbow is an example of a product used for this purpose. It is made of cast iron and is recommended for use with safety valves that have female NPT outlets. When used with safety valves that have flanged outlets ranging from 2 to 4 inches, the aforementioned installation process should be followed.
Drip pan elbows are an essential component in steam applications to manage the condensate that forms as a byproduct. By collecting and directing the condensate, these elbows help prevent potential water damage and ensure the safe and efficient operation of steam systems.
The specific design of the drip pan elbow allows for the collection and redirection of condensate. The elbow's curved shape guides the condensate away from the valve, while the drip pan provides a reservoir to collect any moisture. This prevents the condensate from accumulating within the system, which could lead to corrosion and operational issues.
The use of drip pan elbows is a standard practice in steam service to maintain the integrity and functionality of the equipment while also addressing safety concerns associated with condensate buildup. Proper installation and maintenance of these drip pan elbows are crucial to ensure optimal performance and longevity in steam applications.

They handle condensate from safety valves
Drip pan elbows are recommended for installation on outlet/discharge pipes for safety valves with flanged outlets. They are used in steam services and are made of cast iron. When used with safety valves with flanged outlets (2 to 4 inches), a companion flange, short nipple, and drip pan elbow are used, all of the same size as the valve outlet. The length of the discharge piping must be kept to a minimum.
Drip pan elbows provide a means to handle condensate from safety valves in steam applications. They are designed to collect and redirect condensate that forms in the piping, preventing it from dripping onto the floor or other equipment. This is important for maintaining a safe and dry environment, especially in industrial or commercial settings where slip hazards and equipment damage are concerns.
The elbow shape of the drip pan allows for the condensate to flow smoothly through the pipe, while the drip pan itself provides a reservoir to collect any moisture that may accumulate. This design ensures that condensate is directed away from the valve and piping, preventing potential leaks or corrosion that could occur if the moisture were left undisturbed.
By utilising a drip pan elbow, the condensate from the safety valves can be effectively managed, reducing the risk of water damage and maintaining the integrity of the surrounding equipment and infrastructure. This simple yet essential device plays a critical role in condensate management, especially in steam-intensive applications, by providing a safe and controlled means of handling and redirecting the moisture that forms during the steam release process through the safety valve.

They are recommended for valves with flanged outlets
Drip pan elbows are recommended for installation on outlet/discharge pipes for safety valves with flanged outlets. This is particularly applicable for valves used on steam services. The recommended installation involves using a companion flange, a short nipple, and a drip pan elbow, all of which should be the same size as the valve outlet. This setup is designed to effectively manage condensate from safety valves, especially in steam applications.
When installing a drip pan elbow on a valve with a flanged outlet, it is crucial to keep the length of the discharge piping to a minimum. This is an important consideration to ensure the optimal performance of the drip pan elbow system.
The Kunkle 299-H, 2" drip pan elbow is an example of a product specifically designed for this purpose. It is constructed from cast iron and is suitable for safety valves with female NPT outlets.
By following these recommendations, drip pan elbows can effectively collect and divert condensate away from the valve, preventing potential issues caused by the build-up of moisture or condensate in the system. This not only helps maintain the efficiency of the valve but also contributes to the overall smooth operation of the equipment or system in which the valve is installed.

The length of discharge piping must be kept to a minimum
The drip pan elbow is attached to the outlet/discharge pipe of a safety valve with a female NPT outlet. It is recommended that the drip pan elbow, companion flange, and short nipple all match the size of the valve outlet for optimal performance.
When used in steam service applications, the drip pan elbow helps to collect and manage the condensate that forms as a result of the steam. By keeping the discharge piping short, the condensate has a shorter distance to travel, reducing the risk of backup or overflow.
Additionally, a shorter length of discharge piping can contribute to the overall efficiency of the system. It helps to maintain the desired pressure and temperature levels within the system, ensuring that the condensate is effectively managed and does not affect the performance of the steam application.
It is important for installers and maintenance personnel to follow this guideline of keeping the discharge piping length to a minimum when working with drip pan elbows. This ensures the proper functioning of the condensate management system and helps prevent potential issues such as leaks or improper valve operation.

Installation requires a companion flange, short nipple, and drip pan elbow
The installation of a drip pan elbow requires careful consideration of the components used, including a companion flange, short nipple, and the drip pan elbow itself. These elements work in conjunction to ensure the safe and efficient handling of condensate from safety valves in steam applications.
To begin the installation process, one must first select the appropriate companion flange. This flange should be of the same size as the valve outlet, ensuring a proper fit. The companion flange acts as a mounting base for the assembly, providing a secure connection to the outlet or discharge pipe of the safety valve.
The next component is the short nipple, which serves as a connector between the companion flange and the drip pan elbow. Like the companion flange, the short nipple should also match the size of the valve outlet for a consistent and leak-proof joint. The short nipple creates the necessary distance between the companion flange and the drip pan elbow, allowing for the proper alignment and functionality of the assembly.
Finally, the drip pan elbow is attached to the short nipple. The drip pan elbow is specifically designed to collect and redirect condensate that is discharged from the safety valve. By using a drip pan elbow, the condensate is safely directed away from the valve, preventing potential damage or safety hazards caused by uncontrolled release. The drip pan elbow typically features a female NPT (National Pipe Thread) outlet, ensuring a tight and secure connection with the accompanying components.
It is important to note that the length of the discharge piping should be kept to a minimum during installation. This is to ensure the efficient and effective handling of condensate, as well as to maintain the overall performance of the safety valve assembly. By following these installation guidelines and utilizing the companion flange, short nipple, and drip pan elbow, one can ensure the proper management of condensate from safety valves used in steam applications.
