In the heart of Gujarat’s industrial capital, where engineering excellence meets global standards, the demand for high-performance piping components is relentless. For industries operating in high-pressure, high-temperature, or sub-zero environments, the Weld Neck Raised Face (WNRF) Flange is the undisputed gold standard for safety and reliability. At Pooja Steel and Engineering Company, we have established ourselves as a premier manufacturer of SS 304 and 304L WNRF Flanges in Vadodara, serving as a critical link in the supply chains of chemical, oil and gas, and power sectors. What is a WNRF Flange? A Weld Neck (WN) flange is easily identified by its long, tapered hub that is butt-welded to a pipe. The Raised Face (RF) is the small additional height on the sealing surface where the gasket is placed. Why is this design superior? • Stress Distribution: The tapered hub transfers stress from the flange to the pipe, reducing stress concentration at the base of the flange. • Leak Prevention: The butt-weld connection ensures a leak-proof joint that can withstand extreme turbulence and vibration. • Easy Inspection: Unlike slip-on flanges, the weld on a WNRF flange can be easily radiographed for quality assurance. The SS 304 Advantage: Built for Industrial Durability Stainless Steel 304 is the most widely utilized austenitic steel in the Makarpura and Savli GIDC regions. When you choose Pooja Steel’s SS 304 WNRF flanges, you benefit from: 1. Exceptional Corrosion Resistance: Ideal for the humid conditions of coastal Gujarat and the aggressive chemical atmospheres of Dahej. 2. Structural Integrity: Our forging process ensures a refined grain structure, allowing the flange to maintain its shape and sealing capability under thermal expansion. 3. Low Carbon (304L) Options: For projects involving heavy-duty welding, we provide SS 304L to prevent intergranular corrosion at the weld seams. Serving Vadodara’s Industrial Ecosystem Based in Vadodara, Pooja Steel and Engineering Company is strategically positioned to provide rapid delivery and technical support to Gujarat’s top industrial zones: • Makarpura & Por GIDC: Supporting local heavy engineering and transformer manufacturing units. • Ankleshwar & Panoli: Supplying acid-resistant WNRF flanges for the pharmaceutical and dye industries. • Hazira (Surat): Meeting the heavy-duty piping needs of port-based refineries and steel plants. • Sanand & Halol: Providing precision-machined flanges for the burgeoning automobile and manufacturing sectors.
