Rajendra Pipe Fittings is a recognised Welding Neck Flanges business. The Welding Neck Flanges are supported by Rajendra Pipe Fittings which are in accordance with national and international quality standards. Rajendra Pipe Fittings' state-of-the-art factory is able to manufacture the High Nickel Welding Neck Flanges in bulk orders and in different sizes and lengths. We believe in customer service and therefore we also manufacture the Welding Neck Flanges in custom-sized orders which fulfill our customers' requirements and requests. Rajendra Pipe Fittings is considered to include the Alloy Steel Welding Neck Flanges one of the highest standard. The standard of all our goods is assured because we carry out rigorous sets of quality checks for all our goods before distribution. Some of the tests that our Welding Neck Flanges undergoes are Mechanical Testing Such as Tensile of Area, Flattening Test, Positive Material Identification – PMI Testing, Chemical Analysis – Spectra Analysis, Pitting Resistance Test, Inter-granular Corrosion (IGC) Test, etc.
Welding Neck Flanges can be easily identified in the long tapered neck, which slowly passes from a pipe or fitting to the wall thickness. The long tapered hub offers critical shielding for use in various applications involving high pressure, sub-zero and/or elevated temperatures. The taper is extremely advantageous for the smooth transition from flange thickness to pipe or suitable wall thickness, under conditions of frequent bending, induced by line expansion or other variable forces. Such flanges are drilled to match the inside diameter of the mating pipe or the fitting so that the liquid flow will not be limited. This avoids joint turbulence, and decreases erosion. They also offer excellent stress delivery via the tapered hub and are easily x-rayed for identification of flaws. It types of flange would be welded to a pipe or fitted with a single complete inlet, V weld (Butt-weld).
Welding Neck Flanges were used in a large variety of industries in many applications. Many of the key uses of the Welding Neck Flanges are the chemical industries, petrochemical manufacturing industries, and desalination plants (high-pressure RO-plants and seawater piping). They are also found in applications in various industries such as Architectural industries and Food preparation equipment.
