Threaded Flange

Threaded Flange

Efficient Connection Solutions for Low-Pressure Piping

Our Threaded Flanges, also known as screwed flanges, are designed for quick and easy assembly in piping systems where welding is not feasible. These flanges connect to pipes via internal screw threads, making them ideal for low-pressure, non-critical applications and maintenance-friendly environments.

Key Features & Benefits

• No Welding Required: Perfect for sites where hot work is prohibited or for connecting to threaded pipes without welding equipment.

• Rapid Installation: The screw-on design allows for fast assembly and disassembly, significantly reducing installation time and labor costs.

• Versatile Maintenance: Easily removed for inspection, cleaning, or replacement of piping components, minimizing system downtime.

• Cost-Effective: Lower fabrication costs due to the elimination of welding and non-destructive testing (NDT) procedures.

• Compact Design: Generally lighter and more compact than weld neck flanges, suitable for space-constrained areas.

Technical Specifications

• Size Range: 1/2" to 4" (DN15 to DN100)

• Pressure Classes: Class 150, 300, 600 (typically used in lower pressure ratings)

• Standards Compliance: ASME B16.5, ASME B16.47 Series A & B, EN 1092-1, BS 4504, DIN 2573

• Thread Types: NPT (National Pipe Taper), BSPT (British Standard Pipe Taper), BSPP (British Standard Pipe Parallel)

Available Materials

We manufacture threaded flanges in a variety of materials to suit different fluid services and environmental conditions:

• Stainless Steel: ASTM A182 F304/L, F316/L, F310, F321, F347, 904L

• Duplex Steel: F51 (2205), F53 (2507)

• Alloy Steel: ASTM A182 F11, F12, F22, F91

• Brass & Bronze: For specialized water and marine applications

Applications

Our threaded flanges are widely used in:

• Water supply and distribution systems

• Fire protection sprinkler systems

• Instrumentation and control lines

• Low-pressure steam and air lines

• Temporary piping installations

Quality Assurance & Packaging

Each threaded flange is inspected for thread accuracy, dimensional tolerance, and material grade. We conduct visual inspection and provide Material Test Certificates (EN 10204 3.1) upon request.

Products are carefully packaged in wooden crates or cartons with anti-rust protection to ensure they arrive in perfect condition, ready for immediate installation.
