Overview
The A105 Heavy Barrel Nozzle Flange would typically be used in high-pressure applications, such as those found in refineries, power plants, and chemical processing facilities, where a robust and durable connection between a large nozzle and a pipe is required. The flange ensures that the nozzle is securely attached and can withstand mechanical stress, vibration, and temperature changes.
Heavy Barrel: This term generally refers to a flange design or the profile of the flange. "Heavy barrel" suggests that the flange has a thicker, more robust body, typically to handle higher pressure or to accommodate heavier-duty applications.
Nozzle Flange: A nozzle flange is used to connect a nozzle (often part of a pressure vessel, boiler, or similar equipment) to a piping system. Nozzle flanges are designed to accommodate a pipe that is directly connected to the vessel or other large equipment. These flanges are designed to withstand the forces and pressures involved in the connection.

Applicaiton
Pipeline Systems: A105 body flanges are commonly used in pipeline systems for oil, gas, and water transport. They provide secure connections between pipes, ensuring that the system operates under the required pressure and temperature conditions.
Pressure Vessels and Boilers: A105 flanges are used in high-pressure applications like pressure vessels and boilers, where durability and resistance to thermal expansion are critical.
Chemical Processing: In chemical processing plants, A105 body flanges are used to connect reactors, pumps, and valves, where the strength of the flange material is important to prevent leaks or failures under pressure.
HVAC and Plumbing: In heating, ventilation, and air conditioning (HVAC) systems or industrial plumbing, these flanges ensure a reliable and tight connection between various components, often under high-temperature conditions.
Power Plants: In power plants, especially in steam or water transport systems, A105 body flanges are used to withstand high-temperature and high-pressure conditions, ensuring that fluid or gas flows are efficiently managed.
