In hydraulic systems, square flanges are used to connect a pipe to a component or to another pipe. As the name says, square flanges are squarely formed. Square flanges are manufactured in compliance with various country standards, and they come in a variety of pressure ratings to suit their purpose.

Square flanges provide for seamless passage of liquids through stainless and steel pipes or other hydraulic systems. Square flanges available in a variety of sizes ranging from 1/4 to 6 inches. The most frequent system installation sizes range from 1/2 to 2 inches.

1. Definition: Square flanges, or Slip-On Raised Face flanges, are a type of flange used in piping systems. They are designed to slip over the pipe and then be welded in place. The raised face provides a sealing surface for gasket installation.

2. Design and Construction: Square flanges are typically made of materials such as carbon steel, stainless steel, or alloy steel, depending on the application and the fluid or gas being conveyed. The flange has a circular shape with a slightly larger inner diameter than the outer diameter of the pipe it is intended to fit.

3. Slip-On Design: The Square design of these flanges allows for easy and quick installation. The flange is slipped onto the pipe, and then fillet-welded on both the inside and outside to provide sufficient strength and prevent leakage.

4. Raised Face: One distinguishing feature of Square flanges is the raised face. The raised portion provides a surface for the placement of a gasket, which helps create a tight seal between the flange and the mating flange or equipment.

5. Common Applications: Square flanges are commonly used in applications where quick assembly and disassembly of the piping system are required. They are suitable for low-pressure applications and are often used in industries such as petrochemical, chemical, water treatment, and more.

6. Advantages: Easy to install and remove. Cost-effective compared to other flange types. Suitable for low-pressure applications. The raised face provides a reliable sealing surface.

7. Limitations: Not recommended for high-pressure or critical applications. Welding is required, which may add to the installation time. The raised face may be prone to damage in certain conditions.

Square flanges are a practical choice for applications where ease of installation, cost-effectiveness, and moderate pressure requirements are important factors. They are widely used in various industries and offer a reliable solution for connecting pipes in a piping system.

What is a Square Flanges?

Square flanges come in two materials: steel and stainless steel. It is composed of SF440A steel or SS316 stainless steel. Designed to meet JIS B2291 and JIS F7806 specifications. This means that it is compatible with all Japanese Industrial Standard pipes used in water systems, offshore projects, and oil fields. Square flanges can sustain high pressure from linked pipes and come in three pressure scales: 210kg/cm², 280kg/cm², and 350kg/cm².​

Why square flanges are used in piping?

The square flange is extremely helpful in a variety of high-pressure sectors, including connections between pipes as well as between pipes and other components required to operate a complete system. It is commonly used as a type of pipe fitting. Square flange end connection is welding type and it is termed socket weld or weld-in. The pipe must be inserted into the flange's recessed area or socketed to provide a plain end. Other connections can be customised upon request.

The square flange has several applications, although it is most commonly used in small diameter pipelines. It is not advised for larger diameter pipes with a high weight load functioning inside. However, square flanges are not well suited to working in high torque environments.
