Endüstriyel boru sistemlerinde, Güvenliği sağlamak için doğru flanşı seçmek önemlidir, dayanıklı, ve uygun maliyetli bağlantılar. Mevcut birçok tür arasında, the geçmeli flanş is one of the most commonly used due to its simplicity, affordability, and ease of installation. It is a popular choice for systems operating under moderate pressure and temperature conditions.

This article provides a detailed explanation of what a geçmeli flanş öyle, how it is constructed, faydaları, ortak uygulamalar, and why it is favored in many industries. Whether you’re involved in pipeline design, plant maintenance, or equipment manufacturing, understanding the function and value of slip-on flanges is key to making informed decisions.

Definition of a Slip-On Flange

A geçmeli flanş, often abbreviated as SO flange, is a type of flange that is slipped over the pipe before being welded into place. Kaynak boyunlu flanşların aksine, which require precise alignment and butt welding, slip-on flanges are easier to position and align, making them ideal for quick and efficient installations.

The slip-on flange is typically attached to the pipe with two fillet welds — one on the inside and one on the outside of the flange — providing a strong and stable connection suitable for low to moderate pressure systems.

Structural Features

Slip-on flanges have a simple design that consists of the following elements:

• A flat face or raised face to accommodate gasket sealing

• A slightly larger inner diameter than the pipe’s outer diameter, allowing the pipe to pass through

• Bolt holes arranged around the circumference for connecting to other flanges or equipment

Şu tarihte: Sasaflance, we offer slip-on flanges in a wide range of sizes and materials that comply with international standards such as ASME B16.5, EN 1092-1, and API specifications.

Slip-On Flanşların Avantajları

Slip-on flanges are widely used due to their many advantages, especially in non-critical applications:

1. Kolay Kurulum

Their design allows the pipe to simply slip through the flange opening. This makes alignment much easier and faster than with flanges that require butt welding.

2. Lower Cost

Slip-on flanges typically cost less to manufacture and install. The welding process is less complex and time-consuming, reducing labor costs.

3. Çok yönlülük

These flanges can be used with both pipes and tubing and are suitable for a variety of fluid systems including air, su, yağ, and gas.

4. Compact Design

Slip-on flanges have a shorter overall profile compared to weld neck flanges, making them suitable for systems where space is limited.

5. Available in Multiple Pressure Ratings

Although best for low to medium pressure, slip-on flanges are available in pressure classes ranging from Sınıf 150 sınıfa 600.

Ortak Uygulamalar

Geçmeli flanşlar are widely used in a variety of industries, especially where pressure and thermal cycling are moderate:

• Water treatment and distribution systems

• HVAC and mechanical piping

• Oil and gas utilities (non-critical lines)

• Food and beverage processing

• Chemical and pharmaceutical plants

• Firefighting systems and compressed air lines

Şu tarihte: Sasaflance, we supply slip-on flanges to support global clients in construction, mechanical contracting, and utility infrastructure.

Materials and Standards

Geçmeli flanşlar are available in a variety of materials to meet different operating environments:

• Karbon çeliği for general use

• Paslanmaz çelik for corrosion-resistant applications

• Alaşımlı çelik for higher temperature or pressure resistance

• Dubleks paslanmaz çelik for critical environments like offshore installations

Each material type meets international standards, ensuring compatibility and performance reliability across multiple industries.

Slip-On Flange vs Other Flange Types

To understand where slip-on flanges fit into the larger picture, let’s compare them to other common flange types:

• Slip-On ve Kaynak Boyunlu Karşılaştırması: Slip-on flanges are easier and cheaper to install but offer less strength and sealing capability compared to weld neck flanges

• Slip-On ve Soket Kaynağı: Socket weld flanges are better for small diameter pipes and high pressure; slip-ons are more versatile for general applications

• Slip-On vs Blind Flanges: Blind flanges are used to close pipe ends, while slip-ons are used for pipe-to-pipe or pipe-to-equipment connections

Each flange type has its own strengths, but slip-on flanges remain a go-to option for systems that balance performance with economy.

Installation Guidelines

Proper installation is essential to ensure the effectiveness and safety of a slip-on flange. The steps generally include:

1. Slide the flange over the pipe end

2. Position the flange at the desired location

3. Perform two fillet welds — one inside and one outside the flange

4. Bolt the flange to its mating pair with a gasket in between

While installation is simpler than with other flange types, proper welding and gasket selection remain crucial for system reliability.
