ASTM A105 Weld Neck Slip On Flange
Product Description
WN flange stands for Weld Neck flange. It is a type of flange that is welded to the pipe or equipment it is attached to. The weld neck flange is designed with a taper hub that provides a smooth transition from the flange to the pipe or equipment, reducing stress concentration and increasing the strength of the joint. It also has a raised face or flat face for connecting to another flange or sealing surface with gaskets. WN flanges are commonly used in high-pressure and high-temperature applications.

Carbon Steel Flanges
Carbon Steel Flanges: A Comprehensive Guide
Introduction
Carbon steel flanges are essential components in piping systems, used to connect pipes, valves, pumps, and other equipment. They provide a reliable and leak-proof connection, making them crucial in various industries, including oil and gas, chemical processing, water treatment, and construction. Carbon steel flanges are known for their strength, durability, and cost-effectiveness.
What is a Carbon Steel Flange?
A carbon steel flange is a mechanical component that allows for the joining of two or more parts in a piping system. Flanges are typically flat pieces of metal with holes for bolts, allowing them to be securely fastened to other flanges or equipment. They come in various shapes, sizes, and specifications to meet different application requirements.
Types of Carbon Steel Flanges
Weld Neck Flange: This type features a long neck that provides a gradual transition from the flange to the pipe, making it ideal for high-pressure applications. It is welded to the pipe, ensuring a strong connection.
Slip-On Flange: Designed to slip over the pipe, this flange is easy to install and is commonly used in low-pressure applications. It is typically welded in place for added security.
Blind Flange: A solid flange with no opening, used to seal the end of a piping system. It is useful for closing off a pipeline or for future access points.
Socket Weld Flange: This flange is designed for small-diameter pipes and is welded to the pipe’s socket. It provides a strong connection and is often used in high-pressure applications.
Lap Joint Flange: Used with a stub end, this flange allows for easy alignment and disassembly, making it suitable for applications where frequent maintenance is required.
Threaded Flange: This flange has internal threads that allow it to be screwed onto a threaded pipe, making it suitable for applications where welding is not feasible.
Material Grades
Carbon steel flanges are available in various grades, with the most common being:
- A105: This is a standard grade for carbon steel flanges used in piping systems at ambient and high temperatures.
- A350 LF2: This grade is used for low-temperature applications, providing good toughness and strength.
- A516 Grade 70: Often used in pressure vessels and boilers, this grade offers excellent weldability and is suitable for high-pressure applications.
- Strength: Carbon steel flanges are known for their high tensile strength, making them suitable for high-pressure applications.
- Cost-Effectiveness: Generally more affordable than stainless steel flanges, carbon steel flanges are a popular choice for many applications.
- Versatility: Available in various sizes and types, carbon steel flanges can be used in numerous applications across different industries.
- Weldability: Carbon steel can be easily welded, allowing for secure and permanent connections in piping systems.
Advantages of Carbon Steel Flanges
Applications
Carbon steel flanges are used in a variety of applications, including:
- Oil and Gas: For connecting pipelines and equipment in exploration, production, and refining processes.
- Chemical Processing: In reactors, heat exchangers, and storage tanks where preventing leaks is essential.
- Water Treatment: For connecting pipes in treatment plants and distribution systems.
- Construction: In structural applications where strength and durability are required.
Conclusion
Carbon steel flanges are vital components in the functionality and safety of piping systems across various industries. Understanding the different types, material grades, and advantages of carbon steel flanges can help in selecting the right fittings for specific applications. Whether in oil and gas, chemical processing, or construction, choosing the appropriate carbon steel flanges is crucial for ensuring the integrity and reliability of operations.
