Manufacturing process and features of Slip-On Flange

Manufacturing Process:

Material Selection : Choose appropriate materials based on the application requirements, such as stainless steel, carbon steel, or alloy steel.
Cutting : Cut the raw material to the required size using cutting machines or torches.
Forging : Heat the cut material and forge it under high pressure to form the rough shape of the flange. This process enhances the material’s strength and grain structure.
Machining : Use CNC machines to machine the forged piece to precise dimensions, ensuring smooth surfaces and accurate tolerances.
Drilling : Drill bolt holes according to specified standards like ANSI B16.5 or customer specifications. This ensures proper alignment for bolting.
Heat Treatment : Apply heat treatment processes such as annealing, normalizing, or quenching to improve mechanical properties and relieve internal stresses.
Surface Finishing : Perform surface treatments like polishing, sandblasting, or coating to enhance corrosion resistance and improve aesthetics.
Inspection and Testing : Conduct rigorous inspection and testing, including dimensional checks and non-destructive testing (NDT) methods like ultrasonic or radiographic testing, to ensure quality and reliability.
Marking and Packaging : Mark the flange with relevant information, including material grade, size, pressure rating, and standards compliance. Carefully package the flanges to protect them during transportation.

Features of Slip-On Flange :

Ease of Installation : Slip-On flanges are easy to align and install. The pipe simply slides into the flange before welding, making it simpler to position the flange correctly.
Low Cost : Generally, Slip-On flanges are less expensive compared to other flange types like Weld Neck flanges, both in initial cost and installation.
Versatility : Suitable for a wide range of applications due to their availability in various sizes, materials, and pressure ratings.
Welding Options : Typically requires two welds: one on the inside and one on the outside, ensuring a strong and secure connection.
Flexibility : Can accommodate pipes of different sizes, providing flexibility in piping systems.
Pressure Handling : While they can handle moderate pressure, Slip-On flanges are not recommended for high-pressure applications where stronger weld joints are required.
Precision Engineering : Manufactured to precise dimensional tolerances, ensuring proper fit and alignment in piping systems.
Corrosion Resistance : Available in materials with excellent corrosion resistance properties, making them suitable for corrosive environments.
Standards Compliance : Meets international standards (e.g., ANSI, ASME, ASTM), ensuring compatibility and reliability in various applications.

Frequently Asked Questions

Most frequent questions and answers

What is a slip-on flange?

A slip-on flange is a type of flange designed to fit over the end of a pipe. It is characterized by its ease of installation, as the flange simply slips over the pipe and is then welded into place. Slip-on flanges are commonly used in various piping applications for their simplicity and ease of alignment.

What sizes are available for slip-on flanges?

Slip-on flanges are available in a wide range of sizes to accommodate different pipe diameters. Standard sizes are available, and custom sizes can be manufactured to meet specific requirements.

How are slip-on flanges installed?

Slip-on flanges are installed by sliding the flange over the end of the pipe and aligning it. The flange is then welded to the pipe, both internally and externally, to create a secure connection. A gasket is often used between the flange and the pipe to ensure a leak-proof seal.
