Raised Face Weld Neck Flange – Schedule 40s, 304L Stainless Steel
Keep fluid and gas systems running smoothly under pressure with this Raised Face Weld Neck Flange, built from low carbon 304L stainless steel. Rated to a Pressure Nominal of 10 (10 bar / 145 psi at standard temperatures), it's designed to handle the demands of connecting pipes, valves, and equipment in moderate pressure environments without compromising on strength or safety.
The raised face design concentrates bolt pressure directly onto the gasket, creating a tight, reliable seal that resists leaks even as conditions fluctuate. Its long, tapered weld neck hub is built for durability, butt welding seamlessly to the pipe for a joint that holds firm under high stress. And with a Schedule 40s bore matched precisely to a pipe's wall thickness, providing a smooth, consistent flow path with no unexpected restrictions.
Low carbon 304L stainless steel keeps corrosion at bay long after installation. By resisting carbide precipitation during welding, this flange minimises the risk of rust forming around welded joins, so your system stays protected in demanding industrial settings.
Summary:
- Used to connect sections of pipe, valves, or equipment in fluid and gas systems that require moderate pressure resistance and strong corrosion protection
- PN10 for maximum working pressure of 10 bar at standard temperatures
- Raised face has small raised section around the bore to concentrate bolt pressure onto a gasket for a tight seal
- Long, tapered hub that is butt welded to thepipe, making it great high-stress or fluctuating conditions
- Schedule 40s indicates the wall thickness of the matcvhing pipe and the inner bore of the flange
- Low carbon 304 stainless steel material
- Prevents carbide precipitation during welding, reducing the risk of rust and corrosion near welded joins
Applications:
- Water and Wastewater: Water treatment plants and municipal fluid transport
- Chemical and Food Processing: Low-contamination, mildly corrosive processing lines where hygiene and rust resistance matter
- General Industrial Piping: Low- to moderate-pressure fluid, air, and gas distribution systems
