ANSI B16.11 is a dimensional and pressure-rating standard that covers forged steel fittings such as elbows, tees, couplings, unions, caps, plugs, and bosses. These fittings are typically used for small-bore piping systems where strength, compactness, and leak-proof performance are essential.
Commonly referred to as ANSI B16 11 Fittings, these components are widely applied in oil & gas, petrochemical, refineries, power plants, chemical processing, and hydraulic systems.
ANSI B16.11 Pipe Fittings are manufactured through forging processes that enhance grain structure, mechanical strength, and durability. Due to their superior properties, ANSI B16.11 Forged Fittings are preferred for severe service conditions involving high pressure, vibration, and temperature fluctuations.
These fittings are available with threaded (NPT) or socket weld ends, ensuring flexibility in installation and system design.
The ANSI B16.11 Standard defines dimensions, tolerances, pressure-temperature ratings, marking, and material requirements. Fittinco India Private Limited manufactures fittings in all major pressure classes, including:
Pressure ratings vary based on material grade and operating temperature, ensuring safe and reliable performance.
We manufacture ANSI B16.11 Fittings in a wide range of materials to suit diverse industrial environments:
Commonly produced using ASTM A105 ANSI B16.11 Fittings, these are ideal for high-pressure pipelines and general industrial services.
Known for corrosion resistance, hygiene, and durability, stainless steel fittings are widely used in chemical, food, and pharmaceutical industries.
Manufactured using ASTM A182 ANSI B16.11 Fittings, including grades F1, F5, F9, F11, F22, and F91, alloy steel fittings are suitable for high-temperature and high-pressure services.
These fittings provide high mechanical strength combined with excellent resistance to stress corrosion cracking, making them suitable for offshore and marine applications.
Fittinco India Private Limited offers a comprehensive range of ANSI B16.11 Forged Fittings, including:
Types of Degree commonly manufactured include 45° and 90°, ensuring smooth directional flow and minimal pressure drop in piping systems.
ANSI B16.11 Pipe Fittings are typically available in sizes from 1/8 inch NB to 4 inch NB. End connections include socket weld and threaded (NPT, BSP, BSPT) as per project requirements.
Dimensional accuracy is maintained strictly as per ANSI B16.11 Standard, ensuring interchangeability and ease of installation. Threads conform to ASME B1.20.1 standards, providing leak-proof and secure joints.
The compact design of ANSI B16 11 Fittings allows them to be used in confined spaces where welded fittings may not be practical. Socket depth, wall thickness, and bore dimensions are precisely controlled to maintain strength and flow efficiency. Forging eliminates internal defects, resulting in uniform material properties and enhanced fatigue resistance.
The weight of ANSI B16.11 Forged Fittings depends on nominal bore size, pressure class (3000, 6000, 9000), type of fitting, and material density. Higher pressure classes naturally result in thicker walls and increased weight, providing the required strength and safety margin for critical operations. Approximate weights are calculated as per standard dimensional formulas defined in ANSI specifications.
Every fitting manufactured by Fittinco India Private Limited undergoes comprehensive testing, including:
These checks ensure compliance with ANSI B16.11, ASTM material standards, and customer specifications.
