DIN PN16 Steel Flange

Description

DIN PN16 Steel Flange:

The DIN PN16 Steel Flange is a standardized European flange used to connect pipes, valves, and equipment in pressurized systems with a nominal pressure rating of PN16 (16 bar). It is available in multiple flange types including weld neck (WN), slip-on (SO), lap joint (LJ), socket weld (SW), threaded (TH), and blind flange (BL).

The weld neck flange, also known as a tapered hub or high-hub flange, is designed to reduce stress concentration by smoothly transitioning stress from the flange to the pipe. It is ideal for high-pressure, high-temperature, or critical applications. The weld neck flange comes in two variants: one for use with pipes and another longer version for process equipment. Typically forged and then welded to the pipe, these flanges ensure high mechanical strength and structural integrity in demanding systems.

Key Features:

• Standard: DIN PN16 – supports systems with a nominal pressure of 16 bar

• Available Types: Weld neck (WN), slip-on (SO), lap joint (LJ), socket weld (SW), threaded (TH), blind flange (BL)

• Material: High-quality steel (typically forged for enhanced strength)

• Weld Neck Design: Minimizes stress concentration, ideal for critical systems

• Two weld neck variants: Short type for pipes and long type for process equipment

• Excellent pressure containment and temperature resistance

• Precision-machined for leak-free connections in industrial pipelines

• Ideal for: Oil & gas, chemical processing, water treatment, and mechanical systems
