Plate-type Flat Welding Flange

A Plate-Type Flat Welding Flange is a critical piping component designed to connect pipes,valves,pumps,and other equipment to form a robust and leak-proof piping system.Manufactured from high-quality steel plates through precision cutting and drilling,this flange type features a flat face and is welded to the pipe or fitting,ensuring a secure and durable connection.It is widely used in industrial applications where reliability,ease of installation,and cost-effectiveness are essential.

Key Features and Benefits

Leak-Proof Connection

Provides a tight,secure seal when paired with a flat-face gasket,preventing fluid or gas leakage in low-pressure piping systems.

Ease of Installation and Alignment

The flat face allows for straightforward alignment during assembly,reducing installation time and labor costs.Bolted connections simplify maintenance and disassembly.

Cost-Effectiveness

Manufactured from steel plates rather than forged blocks,making it more economical for low-pressure applications while maintaining sufficient strength.

Durability and Corrosion Resistance

Made from materials such as carbon steel(e.g.,ASTM A105),stainless steel(e.g.,ASTM A182),or alloy steel,with options for protective coatings(e.g.,galvanizing,epoxy)to resist corrosion and extend service life.

Versatility in Applications

Suitable for a wide range of industries,including water supply,HVAC,low-pressure chemical processing,and general industrial piping systems.

Customization

Available in various sizes,pressure ratings(e.g.,PN6,PN10,Class 150),and standards(e.g.,ANSI,DIN,JIS)to meet project-specific requirements.

Technical Highlights

Manufacturing Process:

Cut from steel plates using CNC plasma or laser cutting.

Drilled with precision bolt holes to ensure alignment.

Surface finishing(e.g.,machining)for smooth gasket contact.

Common Materials:

Carbon Steel:ASTM A105,Q235B.

Stainless Steel:ASTM A182 F304/F316.

Alloy Steel:ASTM A182 F11/F22.

Designed for low to moderate pressure and temperature conditions,typically up to PN16/Class 150 and temperatures below 200°C.

Gasket Compatibility:

Paired with flat non-metallic gaskets(e.g.,rubber,PTFE)for optimal sealing.

Standards and Specifications:

Complies with international standards such as ANSI B16.5,EN 1092-1,and DIN 2576.

Applications

Ideal for:

Low-pressure water and wastewater systems

HVAC and ventilation piping

Industrial plumbing and fluid transport

Chemical processing at low pressures

Firefighting and irrigation systems

Summary

The Plate-Type Flat Welding Flange is a practical and economical solution for low-pressure piping systems,offering reliable performance,ease of installation,and broad compatibility.Its simple yet effective design ensures leak-proof connections in diverse industrial and commercial applications,making it a staple component in piping infrastructure.By adhering to international standards and leveraging quality materials,this flange type delivers durability and value for non-critical fluid handling systems.
