Accessories

The 15219-6 standard defines accessory products for use in piping systems. This standard covers accessories typically encountered in oil, gas, and water piping systems. Accessories may be part of the system, merely complementary, or redundant. Accessories covered by the standard include: valves and fittings, filters, strainers, traps, sensors, monitoring systems, check valves, breathing filters and other air supply devices, flanges, and gaskets.

Valves are the most commonly used plumbing accessories, and they come in a variety of sizes and styles. Valves may be manual or automatic, and can range from simple shut-off valves to sophisticated pressure regulators. Valves are typically made of metal and are used to stop or regulate the flow of a fluid or gas. Valves can be used to regulate flow in either direction, depending on their design.

Filters and strainers are a type of accessory used to remove particulates and debris from water and other liquids. Filters are typically made of a semi-permeable membrane or porous material, such as silk or paper, that allows the liquid to pass through but not the particles. Strainers are designed to capture larger particles, such as mud, leaves, and other solid materials.

Traps are used to reduce the amount of air in a plumbing system, and to reduce the accumulation of sediment. Traps are typically V-shaped, and are usually made of metal or plastic. They are joined to a drain pipe, with the V-shaped bottom of the trap acting as an airlock.

Sensors and monitoring systems are used to measure and monitor environmental conditions in a plumbing system. They can be used to detect temperature, pressure, and flow rate, as well as detecting leaks or blockages. Sensors are typically connected to a monitoring system, where they transmit data to a controller or computer.

Check valves are used to prevent the flow of a fluid in a single direction. The valve is usually installed on the outlet side of a pipe, and will only allow fluid to flow in the direction of the valve. If the fluid reverses its flow, the valve closes and the fluid is blocked. Check valves are commonly used to prevent backflow in gravity-fed systems, such as water tanks.

Breathing filters are devices used to filter air that is inhaled or exhaled by animals, such as humans. These filters help reduce the amount of pollutants, dust, and other irritants that are inhaled. Breathing filters are typically made of a fine mesh material, such as fabric or paper.

Flanges are used to connect two pipes or other parts together. They can be threaded, welded, or slip-on. Flanges are commonly used to join two pipes together, and to provide a secure seal. Gaskets are also used in conjunction with flanges to provide a tight seal and to prevent leaks.

The 15219-6 standard covers a wide range of accessories that are used in plumbing systems. These accessories are essential for proper installation and operation of a plumbing system, and are typically used for controlling, measuring, and monitoring the flow of a fluid or gas.
