Slip-On Flange

Product Overview:
The Slip-On Flange is a widely used pipe flange designed to slide over the end of a pipe and be welded both inside and outside for strength and leak prevention. Known for its ease of installation and cost-effectiveness, it is ideal for low- to medium-pressure applications where alignment and assembly speed are priorities.

Key Features:

• Material: Carbon steel, stainless steel, alloy steel (customizable)

• Type: Slip-On (SO) flange

• Standards: ANSI, ASME, DIN, JIS, EN, GB, or customer-specified

• Size Range: DN15–DN2000 (1/2"–80")

• Pressure Rating: PN6–PN40 / Class 150–Class 600

• Face Type: Raised Face (RF), Flat Face (FF), or Ring-Type Joint (RTJ)

• Surface Treatment: Rust-preventive oil, galvanizing, black paint, or custom coating

Advantages:

• Easy to align and install with minimal welding skills

• Lower material and fabrication costs compared to weld neck flanges

• Double welding (inside and outside) ensures a secure, leak-proof connection

• Suitable for frequent disassembly and inspection

• Ideal for systems with moderate flow pressure and temperature

Applications:

• General industrial piping systems

• HVAC and fire protection lines

• Water supply and treatment plants

• Petrochemical and chemical processing

• Shipbuilding and mechanical systems

Customization Options:

• Bore size and thickness

• Drilling pattern and bolt configuration

• Surface finish and branding

• Special materials for high-temperature or corrosive environments
