Rishabh Industries is a reliable Manufacturer and Supplier of ANSI Slip on Flange Dimensions and Standards across India.
Our Manufacturing unit is based in Ahmedabad, Gujarat, India.
A slip-on flange fits over the end of a pipe and is welded both inside and outside to ensure a secure connection.
Design and Structure
Slip-on flanges consist of a flat ring with a bore slightly larger than the pipe diameter, allowing the pipe to “slip on” before welding.
Manufacturers use materials such as carbon steel, stainless steel, and alloy steel to produce them, ensuring they suit various environmental conditions.
Slip-on flanges conform to standards such as ANSI, ASME, and ASTM, which define dimensions and pressure ratings to ensure compatibility and safety.
How Does a Slip On Flange Work?
Installation Process
Installing a slip-on flange involves sliding the flange over the pipe end and positioning it correctly.
The welder then secures the joint by welding the flange to the pipe with two fillet welds—one on the inside diameter and one on the outside diameter.
This double weld ensures strength and prevents leaks. Compared to other flanges, the slip-on flange’s installation is less labor-intensive and requires less precise pipe end preparation.
Advantages of Using Slip On Flanges
Slip-on flanges offer several benefits:
- Ease of alignment: Installers can easily position the flange on the pipe before welding, simplifying installation.
- Cost-effective: Less preparation and faster installation translate into lower labor costs.
- Versatility: Suitable for a wide range of pipe diameters and thicknesses, making it adaptable across applications.
Types of Slip On Flanges
Based on Material
- Carbon Steel Slip On Flange: Common for general-purpose applications due to its strength and affordability.
- Stainless Steel Slip On Flange: Preferred for corrosive environments thanks to its corrosion resistance.
- Alloy Steel Slip On Flange: Used in high-temperature and high-pressure scenarios due to superior mechanical properties.
Based on Pressure Rating and Size
Slip-on flanges come in various pressure classes such as 150#, 300#, 600#, and beyond, conforming to ASME standards. Size ranges typically cover small to very large pipe diameters, ensuring compatibility with virtually any piping system.
How to Choose the Right Slip On Flange
Factors to Consider
Selecting the appropriate slip-on flange depends on:
- Pressure and temperature ratings: Ensure compatibility with system operating conditions.
- Pipe size and compatibility: Match the flange bore with pipe diameter.
- Material selection: Choose materials based on corrosion resistance and mechanical requirements.
- Standards compliance: Verify adherence to industry standards like ASME, ASTM, and API.
Applications of Slip On Flanges
Slip-on flanges are widely utilized in:
- Oil and Gas: For pipelines and refinery equipment requiring moderate pressure connections.
- Chemical Processing: Where quick installation and replacement are necessary.
- Water Treatment: In large-diameter pipe systems carrying water and wastewater.
- HVAC Systems: To connect ducting and piping efficiently.
- General Piping Systems: In construction, manufacturing, and maintenance.
Frequently Asked Questions (FAQs)
- What pressure ratings do slip-on flanges typically support?
Slip-on flanges are commonly rated up to 600 psi, with specific ratings depending on material and standards.
- Can slip-on flanges be used in high-temperature environments?
Yes, when made from suitable alloy materials designed for elevated temperatures.
- How long does installation take compared to other flange types?
Installation is typically faster due to the ease of alignment and simpler welding requirements.
- Are slip-on flanges reusable?
They can be reused if welds and surfaces are inspected and found to be in good condition.
