Frequently Asked Questions

Most frequent questions and answers

A swivel ring flange is a type of flange used in piping systems that allows for rotational movement of one flange relative to the other. It consists of two separate parts: the swivel ring, which can rotate around the flange, and the fixed flange, which remains stationary. This design facilitates alignment and ease of installation in systems where pipe alignment is challenging.

Swivel ring flanges are available in a range of sizes to match different pipe diameters and flange standards. Standard sizes are offered, and custom sizes can be manufactured to meet specific needs.

Swivel ring flanges are installed by positioning the swivel ring and the fixed flange on the pipe or equipment. The swivel ring is allowed to rotate to align with the fixed flange before securing the connection. Bolts are then tightened to ensure a secure and leak-proof seal. Proper alignment and tightening are crucial for optimal performance.

Yes, we offer custom manufacturing solutions for swivel ring flanges to meet specific requirements. Please contact us with your detailed specifications, and we will work with you to produce flanges tailored to your needs.

The lead time for swivel ring flanges depends on the complexity and volume of the order. After reviewing your specifications, we will provide an estimated lead time. We are committed to delivering all projects on schedule while maintaining the highest quality standards.

Yes, swivel ring flanges can be used for both liquid and gas applications, provided they are made from appropriate materials and installed correctly to handle the specific conditions of the system, including pressure and temperature.

Swivel ring flanges are typically made from materials such as carbon steel, stainless steel, alloy steel, and other metals. The choice of material depends on the application’s requirements, including the type of fluid or gas, temperature, pressure, and environmental conditions.

Swivel ring flanges are used in applications where flexibility in alignment is required, such as in systems with misaligned or moving parts. Common applications include pipeline systems in oil and gas, petrochemical industries, and situations where equipment needs to be aligned after installation.

Swivel ring flanges are manufactured to comply with various industry standards, such as ASME B16.5 and ASME B16.47. These standards define the dimensions, tolerances, and material requirements to ensure compatibility and reliability in piping systems.

Swivel ring flanges offer several advantages, including:

Flexibility in alignment: Allows for easy alignment of misaligned pipes or equipment.
Ease of installation: Facilitates installation in challenging or constrained environments.
Reduced stress on piping: Minimizes the stress caused by misalignment.
High reliability: Provides a secure and leak-proof connection when properly installed.

Regular inspection of swivel ring flanges involves checking for leaks and ensuring that the swivel mechanism functions properly. It is important to inspect for any signs of wear, corrosion, or damage that could affect the alignment and integrity of the connection.
