Stainless Steel Flange Hubbed Slip Wn Flange
Flanges are essential components used in piping systems, equipment, and structural applications to connect pipes, valves, pumps, and other machinery. They provide easy access for cleaning, inspection, or modification. Here’s a detailed description: 1. Definition A flange is a protruding rim, collar, or rib on an object (like a pipe, beam, or vessel) used for strength, alignment, or attachment. In piping systems, flanges facilitate the assembly and disassembly of components. 2. Types of Flange... -
Butt welding flange
A butt welding flange (also called a weld-neck flange) is a type of pipe flange designed to be welded to a pipe or fitting using a butt weld (a circumferential weld around the neck of the flange). It is widely used in high-pressure and high-temperature piping systems due to its strength, durability, and leak-proof connection. Key Features of Butt Welding Flanges Weld Neck Design Has a tapered hub that provides reinforcement and reduces stress concentration. The smooth transition from flange... -
Flat Welded Flange with Neck
A Flat Welded Flange with Neck (also known as a ”Slip-On Flange with Hub” or ”Hubbed Slip-On Flange”) is a type of flange designed for easy welding and alignment in piping systems. It combines features of both Slip-On Flanges and Weld Neck Flanges, offering a balance between cost-effectiveness and structural strength. Key Features Hub (Neck) Design Unlike a standard Slip-On Flange (flat-faced), this flange has a short integrated hub (neck) that provides better reinfo... -
Wholesale Slip On Weld Flange
A Slip-On Weld Flange (SO flange) is a type of pipe flange designed to slide over the pipe and then be welded in place, both inside and outside, to ensure a secure connection. It is widely used in piping systems for its ease of installation, cost-effectiveness, and moderate pressure handling capability.

Plate Weld Flange
A Plate Weld Flange (PL Flange) is a flat, circular disc with bolt holes, designed to connect pipes, valves, pumps, and other equipment in piping systems. Unlike welding neck flanges (WN), plate flanges are simpler in design and welded directly to the pipe by fillet welding at the backside. Key Features: ✔ Simple & Cost-Effective – Made from a flat plate, reducing material and machining costs. ✔ Easy Installation – Requires only fillet welding (no beveling needed). ✔ Wide Applications – U... -
Stainless Steel Blind Flange
A blind flange is a type of pipe flange used to seal the end of a piping system, pressure vessel, or valve opening. Unlike standard flanges, it does not have a bore (center hole), making it ideal for isolating or terminating pipelines. Key Features of Blind Flanges Solid Design – No internal opening, providing a tight seal. Pressure Containment – Withstands high pressure, preventing leaks. Easy Installation & Removal – Used for maintenance, inspection, or future expansion. Material Varie... -

ASTM A182 ANSI B16.5 304L 316L Stainless Steel Flange
Description
Flange
1. Application:
For seal or connect of pipe/tub-e lines
2. Material:
304,304L,316,316L,carbon steel or other material on request
3. Standard:
ANSI,DIN,JIS,BS,EN1092-1
4. Size:
DN15 (1/2″) to DN5000 (200″)
5. Type:
Threaded Flanges, Socket Welding Flanges, Blind Flanges, Other FlangesTypes’ Specification
Welding neck
1, Preferred for high-pressure, subzero or elevated temperature
2, Hub is tapered and bored to match pipe’s inside diameter so flow is not restricted, preventing turbulence and reducing erosion
3, Easily radiographed and provides excellent stress distribution
Slip-on
1, Not normally used in high-stress applications due to low hub and weld attachment
2, Silps over outside of pipe
3, Inside of flange welded at hub and end of pipe
Lap joint
1, Used where bolt alignment or access for cleaning is required
2, Similar to slip-on flange when used with lap joint stub end
3, Radius at intersection of flange face and bore to match lap joint stub end
Threaded
1, Used where welding would would be hazardous
2, Designed for low-pressure and non-cyclic applications
3, Bore is threaded to match pipe thread
4, Tapered to seal pipe and flanges
Socket welding
1, For small-diameter chemical processes, hydraulic and stream distribution lines
2, Similar to slip-on flange
3, Counter bore matches pipe bore, allowing unrestricted flow
4, Counter bore from hub side fits pipe’s outer diameter - can insert pipe in socket with fillet weld at hub
Blind
1, Used to close ends of piping
2, Has no bore
3, Permits access to sealed lines
