systems. A Weldoflange combines the features of a weld neck flange and a weldolet, integrating both into a single forged component. This eliminates the need for two separate fittings, reducing welding time, improving structural integrity, and ensuring precision alignment. Weldoflanges are widely used for branch pipeline connections at 90° angles

and are ideal for systems involving high pressure, vibration, and thermal stress. These flanges are particularly suitable for compact spaces where conventional piping connections like tees are not feasible. Available in Standard and Reducing Bore types, they ensure smooth flow transition, minimize turbulence, and reduce fatigue at the weld zone.

We manufacture ASME B16.5 Weldoflanges in pressure ratings from Class 150 to Class 2500 and in sizes ranging from ½″ NB to 24″ NB. Our range includes Butt Weld and Socket Weld outlet flanges, machined with precision to ensure tight tolerances and optimal sealing performance. Available face types include Raised

systems. Unlike standard raised face or flat face flanges, RTJ flanges feature a precision-machined groove on the flange face, which houses a metal ring gasket. When bolted together, the gasket is compressed into the groove, forming a leak-tight metal-to-metal seal. This makes them ideal for high-temperature, high-pressure, and hazardous fluid

applications, especially in refineries, offshore drilling, petrochemical, and power generation industries. Manufactured according to ASME B16.5 and B16.47 Series A & B, Ring Type Joint Flanges are available in pressure classes ranging from Class 150 to Class 2500 and size ranges from ½″ to 48″ (DN15–DN1200). These flanges are commonly

supplied in materials such as Stainless Steel, Carbon Steel, Alloy Steel, Duplex, Super Duplex, and High Nickel Alloys to withstand corrosive and extreme service conditions. RTJ flanges are mostly used in conjunction with RTJ ring gaskets, available in oval or octagonal cross-sections, depending on the flange type. The sealing efficiency

of RTJ connections helps reduce the risk of leakage in systems handling volatile media like hydrocarbons, acids, gases, and superheated steam. These flanges are also compatible with compact flange designs used in modern offshore platforms. As one of the leading RTJ Flange suppliers, we ensure precise machining, accurate groove dimensions,

and strict tolerance control as per international standards. Whether for sour gas pipelines or subsea manifolds, our RTJ flanges are trusted for long-term durability, metallurgical integrity, and perfect sealing in extreme conditions.
