Threaded Flanges Compatibility: Unraveling the Types of Pipes and Limitations



Threaded flanges, known for their simplicity and ease of installation, provide a versatile solution in various piping systems. However, the compatibility of threaded flanges is closely tied to the types of pipes used in the system. In this blog post, we'll explore the types of pipes that are compatible with threaded flanges, highlighting their advantages and addressing potential limitations.

Types of Pipes Compatible with Threaded Flanges:

1. Steel Pipes:

  - Advantages:

    - Threaded flanges are highly compatible with steel pipes, offering a robust and reliable connection.

    - Steel pipes provide durability and strength, making them suitable for various applications.

2. Stainless Steel Pipes:

  - Advantages:

    - Threaded flanges are commonly used with stainless steel pipes, benefiting from the corrosion resistance of stainless steel.

    - Stainless steel pipes and threaded flanges are frequently employed in industries requiring resistance to harsh environments.

3. Alloy Steel Pipes:

  - Advantages:

    - Threaded flanges can be compatible with alloy steel pipes, providing a secure connection in applications where enhanced strength and durability are required.

    - Alloy steel pipes are often used in high-temperature and high-pressure environments.

4. Brass Pipes:

  - Advantages:

    - Threaded flanges can be utilized with brass pipes, especially in applications where corrosion resistance and aesthetics are priorities.

    - Brass pipes are commonly found in certain low-pressure and non-critical environments.

5. Copper Pipes:

  - Advantages:

    - Threaded flanges can be compatible with copper pipes, offering a reliable connection for various applications.

    - Copper pipes are known for their excellent conductivity and corrosion resistance.

6. PVC Pipes:

  - Advantages:

    - Threaded flanges are suitable for use with PVC (polyvinyl chloride) pipes in certain non-critical and low-pressure applications.

    - PVC pipes are lightweight and corrosion-resistant, making them suitable for specific industries.


Threaded flanges demonstrate compatibility with various types of pipes, offering advantages in terms of simplicity, ease of installation, and versatility. Steel, stainless steel, alloy steel, brass, copper, and PVC pipes can all be effectively used with threaded flanges in specific applications. However, engineers and designers must consider the limitations associated with size constraints, high-pressure environments, and high-temperature conditions.

Understanding the compatibility of threaded flanges with different types of pipes enables professionals to make informed decisions based on the specific requirements of their piping systems. Whether in industrial, residential, or commercial applications, the judicious selection of pipe materials and threaded flanges contributes to the overall reliability and efficiency of the piping infrastructure.
