Product Introduction
Welding neck flange is a common flange connection method, which is usually used to connect equipment such as pipes and valves, and has the characteristics of reliability and high sealing.
The following is an introduction to the main characteristics, dimensions, pressure, production and application of neck butt welding flanges:
Features
The main feature of the weld neck flange is that it has a raised neck on one side of the flange, usually a cylindrical pipe, which provides the support and sealing function of the connected equipment. At the same time, the flange connection method has the following characteristics:
Reliability: The welded neck flange can withstand high pressure, high temperature and high load conditions, and has good reliability and stability.
High sealing performance: This flange connection method uses sealing gaskets to ensure sealing performance, usually made of metal gaskets, rubber gaskets and other materials.
Easy to install: The installation of neck butt weld flanges is relatively simple and can usually be done without dismantling the connecting pipes or valves.
Size and Pressure Rating
The dimensions and pressure ratings of weld neck flanges usually comply with international standards, such as ASME B16.5 and DIN 2632-2638. The main parameters are as follows:
Size range: 1/2" to 24" (DN 15 to DN 600)
Pressure Rating: 150# to 2500# (PN 6 to PN 400)
Connection method: welding, thread, flange, etc.
Manufacture
The production of neck butt welding flange usually requires the following steps:
Neck: According to equipment requirements and size requirements, the neck is made by forging or casting.
Manufacture of the flange: Connect the neck and the flange body through machining, stamping and other processes.
Install gaskets: install gaskets between flange connection surfaces to ensure sealing performance.
Application
Weld neck flanges are widely used in many industries, including oil, gas, chemical, electric power, water treatment, food, pharmaceutical and other industries. The following is an introduction to the application of weld neck flanges:
Oil and Gas Industry
In the oil and gas industry, weld neck flanges are used to connect various pipelines and equipment, such as oil wells, refineries, natural gas processing plants, oil pipelines, chemical storage tanks, etc. This flange connection can withstand high pressure, high temperature and corrosive media, ensuring the safe and efficient operation of the equipment.
Chemical Industry
In the chemical industry, neck butt welding flanges are used to connect various chemical equipment, such as reaction kettles, distillation towers, heat exchangers, storage tanks, pipelines, etc. The flange connection can withstand high pressure, high temperature and corrosive media, ensuring the safe and efficient operation of chemical equipment.
Power Industry
In the power industry, neck butt welding flanges are used to connect pipes and equipment for various conveying media, such as steam pipes, hot water pipes, cooling water pipes, generator sets, boilers, etc. This flange connection can withstand high temperature, high pressure and corrosive media, ensuring the safe and efficient operation of electrical equipment.
Water treatment industry
In the water treatment industry, welded neck flanges are used to connect various pipes and equipment for conveying water, such as sewage treatment equipment, water supply equipment, water pumps, water treatment tanks, etc. The flange connection can withstand high pressure, high temperature and corrosive media, ensuring the safe and efficient operation of water treatment equipment.
Food and pharmaceutical industry
In the food and pharmaceutical industries, weld neck flanges are used to connect various pipelines and equipment conveying media, such as food processing equipment, pharmaceutical equipment, conveying pipelines, etc. This flange connection can ensure the cleanliness and sterility of the medium, which meets the hygienic standards of the food and pharmaceutical industries.
In general, weld neck flanges are widely used in various industries to ensure the safe and efficient operation of equipment.
