Stainless Steel Weld Neck Flange
We are engaged in delivering high end Weld neck flange (WNRF) which is tested for its durability and stability by our expert supervisors. The usage of this product is well defined and the product is widely used accordingly. Our Weld neck flange has a long pointed focal point hub and thus becomes easy to distinguish it. Weld-Neck flanges or welding-neck flanges are best suited for severe service conditions, whether loading conditions are substantially constant or fluctuate between wide limits.
This product is dimensionally accurate and exhibits great levels of accuracy and precision. We ensure that the product delivers maximum output and comes within the budget of our clients. Our product designers ensure that they communicate with the clients and understand the various problems faced by them. This enables our team to manufacture products that may fulfill the various technological aspects. The product is exported to places near and far which speak volumes of the technological sophistication of our product. Further on to elaborate on the technical aspect of our product. Weld neck Flanges are drilled (machined) with the wall depth of the flange having the similar dimensions of the matching pipe. The lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore. They are normally used for high-pressure, cold or hot temperature.
Stainless Steel Weld Neck Flange are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting. The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. The smooth transition from flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces. These flanges are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection.
Stainless Steel Weld Neck Flange is used where high pressure is required. These pipe flanges attach by welding the pipe to the neck of the flange. It helps in reducing the stress concentration from the bottom of the center. Vikram Forge Fittings offers the best weld neck flanges with a hub in varieties of specifications, grades, materials and sizes. These type of flanges have a long tempered hub and used in applications where high pressure is a factor. When ordering a weld neck flange, it is essential to identify the schedule pipe is being used for. This is because the inside diameter of the flange will match the inside diameter of your pipe.
