Country Of Origin: India

Carbon steel buttweld fittings are essential components used to change the direction, branch off, or reduce the size of a piping system. They are joined to pipes through butt welding, which creates a strong, leak-proof, and permanent.

Common Types of Fittings

Elbows: Used to change the flow direction. Available in 90°, 45°, and 180° (return bend) angles. They come in Long Radius (LR) for smoother flow or Short Radius (SR) for tight spaces.
Tees: T-shaped fittings with three outlets. Equal Tees have three identical diameters, while Reducing Tees have a smaller branch outlet.
Reducers: Connect pipes of different diameters. Concentric Reducers share the same centerline (ideal for vertical lines), and Eccentric Reducers have an offset centerline (ideal for horizontal lines to prevent air pockets).
Caps: Used to seal the end of a pipeline.
Crosses: Connect four pipelines at a single point.
Stub Ends: Used in combination with lap joint flanges to allow for easy inspection and maintenance.

Materials and Grades

Buttweld fittings are primarily manufactured from wrought carbon steel according to ASTM A234 standards.

ASTM A234 WPB: The most common grade for moderate to high-temperature services.
ASTM A420 WPL6: Specifically designed for low-temperature applications.
MSS-SP-75 WPHY: High-yield grades (e.g., WPHY 42, 52, 65, 70) used for high-pressure transmission pipelines.

Standards and Specifications

Dimensions & Tolerances: Manufactured according to ASME B16.9 (standard wrought fittings) and ASME B16.28 (short radius elbows).
Schedules: Unlike threaded fittings that use pressure classes, buttweld fittings are specified by pipe schedule (e.g., Sch 40, Sch 80, Sch XXS), which determines wall thickness and pressure rating.
Sizes: Typically range from 1/2" NB to 60" NB.
