Feature
Key Features of Weld Neck Flanges: Tapered Hub: The distinctive, long tapered neck gradually transitions the thickness from the pipe to the flange, reducing stress concentration at the joint. Butt-Weld Connection: Designed to be butt-welded to pipes, providing a stronger, more reliable, and leak-proof joint compared to fillet welds. Matched Bore: The internal diameter (ID) of the flange matches the pipe ID, ensuring a smooth, unobstructed flow and reducing erosion/turbulence. High Pressure/Temperature Resistance: Suitable for severe service conditions (high pressure/temperature), meeting, for example, ASME B16.5 standards. Durability: Often forged for maximum strength, ensuring long service life in harsh environments. Versatile Faces: Available in Raised Face (RF), Flat Face (FF), or Ring Type Joint (RTJ) configurations. Sizes & Materials: Available in sizes ranging from inch to inches (and larger), and materials including carbon steel, stainless steel (e.g., F304/L, F316/L), and alloy steel.

Packaging Details
1. Packing and Material Details (Packaging) Protection: To prevent damage to the surface (especially for galvanized coatings), puddle flanges are typically packed in wooden crates or, for smaller items, in corrugated boxes filled with protective material. Packaging Type: Industrial-grade items areoften found in HDPE bags or wooden crates. Components Included: Often come with stainless steel (SS) tension bands for securing to the pipe. Marking: Packed items are marked with essential information including the manufacturer's brand, grade of material, lot number, size, and type. Tradeindia Tradeindia +4 2. Product Specifications (Material & Design) Materials: Common materials include Mild Steel (MS) with hot-dip galvanization, Stainless Steel (SS304/SS316), PVC, and Rubber/EPDM. Dimensions: Available in sizes ranging from 25 mm to over 1200 mm (1 inch to 48+ inches). Thickness: The flange plate is typically 6 mm thick or greater. Design: Features a central opening for the pipe and a wide collar to act as a barrier. The surface is often grooved or ribbed to provide better anchoring in concrete. Pressure Rating: Typically designed to withstand pressures of PN6, PN10, or PN16. Rajtilak Metal Rajtilak Metal +6 3. Installation and Sealing Method Placement: Installed during the construction phase, prior to pouring concrete. Securing: The flange is placed over the pipe and secured with bands or welded to ensure it does not move during concrete pouring. Sealing: To ensure a watertight seal, the flange is often embedded in the middle of the wall, providing at least 50mm of concrete coverage on all sides. Flexible Options: Rubber or NBR material options are used for superior sealing in high-pressure or chemically sensitive environments. VIPseal VIPseal +4 4. Key Applications Water Tanks: Essential for inlet/outlet pipes to prevent leakage. Basements & Foundations: Prevents groundwater seepage. Sewage/Drainage: Stops leakage in manholes and wastewater structures. Udhhyog Udhhyog +1 5. Standards and Pricing Standards: Commonly designed to meet ASME B16.5, ASTM A105, or ASTM A182 standards. Price Range: GI Puddle Flange (~INR 500 1200), SS Puddle Flange (~INR 900 2500), PVC Puddle Flange (~INR 300 800).

About Weld Neck Flange

Weld Neck Flange is flanges that designed to be joined to a piping system by butt welding. This kind of flange include lots of specification.

Weld Neck Flange is expensive because of its long neck and cost of people for contact WN flange with pipeline or fitting but is preferred for high-stress applications. The necks, or hubs, transmits stresses to the pipeline.

The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck Flange. The bore of Weld-Neck flange matches bore of the pipeline, reducing turbulence and erosion.
