BUTT-WELD FITTINGS
Used in large diameter, high-pressure pipelines. Welded directly to pipes for permanent installations.
FittingDescription
Elbow (45°, 90°, 180°)
Changes direction of flow. 45° for slight turns, 90° for right-angle turns, and 180° for return flow.
Tee (Equal / Reducing)
Creates a 90° branch. Equal tee connects same-size pipes; reducing tee connects pipes of different diameters.
Reducer (Concentric / Eccentric)
Concentric: used for vertical lines; symmetrical. Eccentric: used for horizontal lines to prevent air pockets.
End Cap
Closes the end of a pipe, preventing flow.
Stub End
Used with lap joint flanges for easy disassembly in flanged connections.
Elbow (Threaded / Socket Weld) Turns the flow direction in the pipeline (usually 90° or 45°).
Tee (Threaded / Socket Weld) Divides flow into two branches or joins three flows.
Coupling (Full / Half) Connects two pipes together; half coupling connects pipe to equipment or valve.
Union Allows quick and easy disconnection of pipe segments.
Plug Closes the pipe end temporarily or permanently.
Cap Similar to plug but covers the outside diameter of the pipe.
Bushing Connects pipes of different diameters with internal and external threads.
Cross Four-way fitting that splits flow into three branches at 90° angles.
Male / Female Connector Connects tubing to male/female threads respectively.
Bulkhead Union Passes tubing through panels or walls while maintaining a sealed connection.
Union (Straight / Elbow / Tee) Joins two or more tubes inline (straight), at 90° (elbow), or branches flow (tee).
Reducer Connects tubes of different sizes while maintaining leak-proof connection.
Slip-On Flange Slips over the pipe; easy to install and weld.
Weld Neck Flange High strength, used in high-pressure and high-temperature systems.
Blind Flange Closes the end of a piping system.
Socket Weld Flange For small-size, high-pressure systems; pipe is inserted into socket.
Threaded Flange Screws onto threaded pipe without welding; used in low-pressure systems.
Lap Joint Flange Used with stub ends; allows rotation for bolt alignment.
Orifice Flange For flow measurement in pipelines using an orifice meter.
🔩 What Are Refractory Anchors? Refractory anchors are metal fixing or fastening components embedded into refractory linings to securely tie the refractory to the kiln shell or support structure. They:
V-Type
Standard castable anchoring; simple & cost-effective
Y-Type
Better pull-out resistance; deeper support for thicker lining
U-Type
Handles differential expansion; good in modular/precast linings
Zig-Zag / Corrugated
Larger surface contact; excellent mechanical interlock
Straight / Stud
Simple pin anchors for castable & bricks
Custom
