Product Name

Stainless Steel / Carbon Steel Pipe Flange (Weld Neck / SlipOn / Blind, ANSI/ASME/DIN Standard)

Product Overview

A Pipe Flange is a critical connecting component used to join pipes, valves, pumps, and other equipment in piping systems. Flanges provide easy access for maintenance, inspection, or modification. They are widely used in oil & gas, chemical processing, waterworks, and power plants.

Key Features

Materials:

Stainless Steel (304/316/316L) – Corrosionresistant for harsh environments.
Carbon Steel (A105/A350 LF2) – High strength for highpressure applications.
Alloy Steel (F11/F22) – Heatresistant for steam & hightemperature services.

Types:

Weld Neck Flange (WN) – Reinforced neck for highpressure systems.
SlipOn Flange (SO) – Easy installation, costeffective for lowpressure use.
Blind Flange (BL) – Used to seal pipe ends or vessel openings.
Socket Weld Flange (SW) – Compact design for smalldiameter highpressure pipes.
Threaded Flange (TH) – No welding needed, ideal for explosive environments.
Lap Joint Flange (LJ) – Used with stub ends for easy alignment.

Pressure Ratings:
ANSI/ASME Classes: 150, 300, 600, 900, 1500, 2500.
PN Ratings (DIN): PN6, PN10, PN16, PN25, PN40, PN64.

Facing Types:

Raised Face (RF) – Standard for most applications.
Flat Face (FF) – Used with cast iron & soft gaskets.
RingType Joint (RTJ) – Highpressure, hightemperature sealing.

Advantages

✔ LeakProof Connection – Ensures secure sealing with gaskets & bolts.
✔ High Durability – Resists extreme pressure, temperature, and corrosion.
✔ Easy Assembly & Disassembly – Simplifies maintenance & system modifications.
✔ Wide Compatibility – Matches standard pipe sizes (NPS ½” to 60”).
