Frequently Asked Questions

Most frequent questions and answers

A square flange is a type of flange with a square-shaped plate that features four holes for bolting. Unlike traditional round flanges, square flanges have a distinct square shape, which can be advantageous in certain applications for aligning with square or rectangular piping systems and equipment.

Square flanges come in various sizes to accommodate different pipe dimensions and pressure ratings. Standard sizes are available, and custom sizes can be manufactured to meet specific requirements.

Square flanges are installed by aligning the flange with the corresponding pipe or equipment and bolting it into place. A gasket is usually placed between the flange and the connection surface to ensure a leak-proof seal. Proper alignment and bolt tightening are crucial for achieving a secure and effective connection.

Yes, we offer custom manufacturing solutions for square 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 square 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, square 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.

Square flanges are made from a variety of materials including carbon steel, stainless steel, alloy steel, and other metals. The choice of material depends on the specific requirements of the application, such as the type of fluid or gas, temperature, pressure, and environmental conditions.

Square flanges are used in applications where a square connection is needed, often to align with square or rectangular ducts, pipes, or equipment. They are commonly found in industries such as HVAC, chemical processing, and manufacturing, where they facilitate easy and secure connections in non-standard setups.

Square flanges may not always adhere to the same standards as round flanges, but they can be manufactured to comply with specific industry standards or custom specifications. It is important to verify the standards applicable to the particular square flange used in your application.

Square flanges offer several advantages, including:

Alignment: Ideal for applications requiring alignment with square or rectangular components.
Design Flexibility: Provides options for custom configurations where round flanges may not be suitable.
Ease of Use: Simplifies connections in specific systems that use square or rectangular fittings.

Regular inspection of square flanges involves checking for leaks, ensuring proper alignment, and examining the condition of the gasket and bolts. It is important to inspect for any signs of wear, corrosion, or damage that could affect the integrity of the connection.
