We also supply fittings in advanced corrosion-resistant materials like Duplex and Super Duplex Steels (UNS S31803, S32750, S32760), and a wide variety of Nickel Alloys including Inconel (600, 601, 625, 718, 725), Incoloy (800H/HT, 825, A286, Alloy 20), Monel (400, K500), and Hastelloy (B2, C22, C276).
Our buttweld fittings are available from ¼" NB to 24" NB (Seamless) and 4" NB to 72" NB (Welded), with wall thickness ranging from Sch 5s to Sch XXS. The product line includes Elbows (1D, 1.5D, 3D, 5D), Return Bends, Equal & Reducing Tees, Crosses, Stub Ends (Long & Short), Reducers (Concentric & Eccentric), and Pipe End Caps.
Known for their dimensional accuracy, leak-proof connections, and corrosion resistance, our Buttweld Fittings are extensively used in critical sectors like Oil & Gas, Petrochemical, Power Generation, Pharmaceutical, Water Desalination, and Process Industries. All fittings are tested to meet international standards and can be provided with MTCs, NACE compliance, and Third-Party Inspection upon request.

Buttweld Elbows are essential components used to change the direction of flow in a piping system. Available in 90°, 45°, and 180° angles, these elbows are designed to withstand high pressure, corrosive environments, and temperature fluctuations. We also offer Male and Female Elbows for special process requirements.
Buttweld Tees are used to either combine or divide fluid flow in process pipelines. We offer both Equal Tees (for same-size branch connections) and Reducing Outlet Tees (for different-sized branching). These tees ensure smooth flow, structural strength, and leak-proof connections, making them suitable for high-pressure and corrosive environments.
Buttweld Cross Fittings are used to connect four pipe sections at right angles, making them ideal for complex pipeline layouts in industries where multi-directional flow is required. We offer both Equal Crosses (with all four ends the same size) and Reducing Crosses (with one or more branches of smaller diameter).
Pipe End Caps are used to seal the ends of piping systems or pressure vessels, providing a secure and reliable closure. These fittings help prevent contamination, leakage, and environmental exposure, making them essential for pipeline protection and system shutdowns.
Stub Ends are primarily used with Lap Joint Flanges, allowing quick disassembly and inspection in piping systems. They are ideal for systems that require frequent dismantling for cleaning, inspection, or replacement, especially in low-pressure and non-critical applications.
Nipples are short lengths of pipe used to connect two fittings or pipes in a piping system. Swage Nipples are used to transition between pipes of different diameters, while Pipe Nipples are straight connectors typically threaded at both ends.
Buttweld fittings are essential in creating strong, leak-proof connections in high-pressure, high-temperature, and corrosive environments across various industries.
Used in upstream and downstream pipelines, refineries, and terminals for secure welded connections that withstand extreme pressure and temperature.
Ideal for transporting corrosive fluids and gases in reactors, distillation units, and processing lines due to their seamless, durable construction.
Extensively used in boiler and steam piping systems in nuclear, thermal, and combined cycle power stations.
Used in high-performance marine pipelines and exhaust systems where vibration and corrosion resistance are critical.
Ideal for high-flow pipelines in desalination plants, sewage systems, and industrial effluent treatment lines.
Commonly used in paper mills, food processing, pharmaceuticals, and structural pipelines for their reliability and smooth fluid flow.
