Referance Standard and Grade:
ASTM A105: Standard forged carbon steel pipe components for environmental and high temperature / high pressure systems.
ASTM A182: The standard for alloy and stainless threaded flanges.
Common alloy grades: F5, F9, F11, F22, F91; Stainless steel grades: F304, 304/, F316, F316L.
Although threaded pipe flanges come in different sizes, threaded pipe fittings are mostly used for small-diameter pipes. (Normally less than 4 inches)
On the other hand, it is not compatible with thin-walled pipe systems because there is no room for threading.
Types:
1. One seals the two pipe ends with a certain sealing surface and a lens pad. This type is mostly used for ammonia production but has been used less recently, and the lens pad has been replaced by a metal ring.
2. The other is the same as a normal flange and is sealed with two flange sealing faces.
Specific Industrial Applications of Threaded Flange
Threaded flanges are essential in piping systems for various industries where safety, durability, and reliability are critical. Listed below are examples of sectors that utilize these components:Oil and Gas
In offshore platforms, the flanges connect piping systems that transport oil and gas from the seabed to the surface. They can withstand harsh environmental conditions, including strong currents, corrosive saltwater, and challenging weather. Similarly, they are widely used in refineries and processing plants in onshore oil and gas operations.Petrochemical and Chemical
The petrochemical and chemical sectors frequently encounter high pressures, corrosive substances, and extreme temperatures. The flanges establish connections between pipes and valves used in refining and handling chemicals, petroleum, and gas. Due to their robust construction and ability to prevent leaks, they are well-suited for these challenging industrial applications.Pharmaceutical and Food Processing
Carbon steel flanges are preferred in pharmaceutical and food processing applications due to their corrosion resistance and ease of cleaning. They are also compatible with stringent cleaning agents and disinfectants. In addition, their smooth surface finish minimizes the accumulation of residue and bacteria, facilitating sterilization procedures.Power Generation
Thermal, nuclear, and renewable energy facilities heavily rely on flanges to establish secure connections in critical elements. These include steam lines, condensers, turbines, and other components. The flanges are also employed to guarantee leak-free joints and endure the effects of elevated temperatures and high pressures.Shipbuilding and Maritime
Threaded flanges are employed in the fuel systems of ships and marine vessels. They connect the fuel pipelines, ensuring a secure transfer from storage tanks to engines. This is important given the criticality of fuel supply for propulsion and power generation in marine operations.
