BB Infras is one of the most reputed and trusted suppliers, stockists, and exporters of high-quality Buttweld Pipe Fittings used across oil & gas, refinery, petrochemical, chemical, water treatment, marine, construction, and power generation industries. Our wide range includes elbows, tees, reducers, caps, crosses, stub ends, and long/short-radius pipe bends manufactured as per ASME, ASTM, MSS-SP & international dimensional standards.
As a global supplier, BB Infras maintains a large inventory of Carbon Steel, Stainless Steel, Alloy Steel, Duplex & Super Duplex, Nickel Alloy and Galvanized Buttweld Fittings in all sizes, schedules and pressure classes. We supply these fittings to major EPC contractors, fabrication companies and industrial projects in India as well as the Middle East, Europe, Africa, and Southeast Asia.

All our buttweld fittings are produced from high-grade raw materials using advanced manufacturing processes such as hot forming, cold forming, mandrel bending and heat treatment to ensure superior mechanical strength, weldability, corrosion resistance and dimensional accuracy. Every fitting is subjected to stringent quality checks, NDT testing, PMI and certification to meet global project requirements.
The buttweld construction provides smooth, leak-proof, and permanent joints, making these fittings ideal for high-pressure, high-temperature, and corrosive service environments. Their seamless flow transition minimizes pressure losses and reduces turbulence within the pipeline system, increasing overall efficiency and service life.
BB Infras supplies fittings in all standard types: 45°/90°/180° elbows, equal & reducing tees, concentric & eccentric reducers, long & short stub ends, pipe caps, crosses, and bends. Custom-fabricated fittings for heavy-wall, non-standard radius or project-specific designs are also available on request.

Plumbing & Pipe Fittings are essential components used in piping systems to ensure safe, leak-free, and efficient fluid or gas transfer across various industries. They connect, control, regulate, and support pipelines operating under different temperature and pressure conditions.
Plumbing & Pipe Fittings are widely used in onshore and offshore drilling operations, refinery pipeline systems, gas distribution networks, and high-pressure fluid transfer. Their corrosion resistance and temperature tolerance make them ideal for harsh environments.
These fittings are crucial in chemical processing plants, acid/alkali lines, solvent transfer systems, and hazardous chemical handling. Materials are selected based on corrosion resistance and compatibility with chemicals.
Plumbing & Pipe Fittings are used in boiler lines, steam pipelines, turbine systems, and cooling water networks. They withstand high pressure and extreme temperatures in thermal, nuclear, and renewable energy plants.
Applications include RO systems, filtration units, pumping stations, and municipal water supply lines. Fittings provide durability, corrosion resistance, and long-term leak-proof performance.
Stainless steel sanitary fittings ensure hygienic flow in dairy units, breweries, beverage manufacturing, and food processing systems. They prevent contamination and meet high hygiene standards.
Plumbing & Pipe Fittings are used in cleanroom piping, purified water systems, drug manufacturing units, and sterile processing operations. They comply with GMP and maintain contamination-free fluid handling.
Used in firefighting systems, HVAC networks, plumbing systems, and building pipelines. Plumbing & Pipe Fittings ensure reliable flow and structural stability across large infrastructure projects.
Marine-grade fittings are used in seawater pipelines, ballast systems, and fuel/oil transfer lines. They offer high resistance to corrosion in saltwater environments.
Essential for fuel injection lines, hydraulic systems, coolant pipelines, and high-pressure circuits. They withstand vibration, heat, and pressure fluctuations in vehicles and aircraft.
Plumbing & Pipe Fittings are used in slurry pipelines, ore processing systems, and high-abrasion environments. Alloy steel fittings provide strength, wear resistance, and durability.
Stainless Steel, Brass, Copper, CPVC, UPVC, and GI are most commonly used depending on temperature, pressure, and application.
CPVC withstands higher temperatures (up to 93°C), while UPVC is ideal for cold water lines. Both offer corrosion resistance and easy installation.
