Frequently Asked Questions About Threaded Flanges
Our FAQ module on threaded flanges provides detailed answers to common questions, ensuring you have all the information you need about this essential piping component. Whether you are dealing with high-pressure applications or environments where welding is not an option, our FAQs cover everything from installation to material specifications, helping you make informed decisions.
A threaded flange, also known as a screwed flange, connects to a pipe using a screw thread. The pipe has a male thread, and the flange has a female thread, allowing them to be screwed together. This type of flange is ideal for smaller diameter pipes and situations where welding is hazardous.
Threaded flanges are commonly used in refineries, manufacturing facilities, and shipyards, particularly in environments where welding is not feasible due to the highly flammable or explosive nature of the materials being transported. They are also used in high-pressure applications and small diameter piping systems.
Threaded flanges are made from various materials including carbon steel (e.g., ASTM A105), alloy steel (e.g., ASTM A182 F1-F12), stainless steel (e.g., ASTM A182 F304-316), low temperature steel (e.g., ASTM A350 LF2), and high-performance steel (e.g., ASTM A694 F42-F70). The choice of material depends on the specific requirements of the application.
Threaded flanges ensure a leak-proof connection through the use of tapered threads, which tighten as they are screwed together. Additionally, a seal weld can be applied around the junction of the pipe and flange if conditions allow for welding, providing extra security against leaks.
Threaded flanges are available in sizes ranging from 1/4" to 6" (DN8-DN150) and pressure ratings from Class 150 to Class 2500 (PN2.5 to PN400). The specific size and pressure rating required will depend on the application and the standards being followed, such as ASME, ANSI, or DIN.
Threaded flanges come with various facing types including flat face (FF), raised face (RF), tongue (T), groove (G), female (F), male (M), and ring type joints face (RJ/RTJ). The choice of facing type depends on the sealing requirements and the standards being followed.
Threaded flanges are generally not recommended for high-temperature applications, especially where post-weld heat treatment is not possible. They are more suitable for applications at or near atmospheric temperature and where welding poses safety risks.
The manufacturing of threaded flanges is governed by various standards including ASME ANSI B16.5, ASME ANSI B16.47, API 605, API 6L, MSS SP 44, CSA Z245.12, EN1092-1, DIN2565-2569, BS1560, BS 4504, AFNOR NF E29-200-1, ISO7005-1, AS2129, JIS B2220, and UNI 2276-6090. These standards ensure the flanges meet specific dimensional and material requirements.
Yes, threaded flanges are economical and time-saving devices as they do not require welding. This makes them easier and quicker to install, especially in environments where welding is hazardous or impractical. They are ideal for non-cyclic applications and small diameter piping systems.
