Elbows (LR & SR)

Used to change flow direction. Available in Long Radius (1.5D) for efficiency and Short Radius (1D) for tight spaces. 45°, 90°, and 180° bends.

StdASME B16.9

Pipe Tees

Used for 90° branching. Equal Tees have the same branch diameter, while Reducing Tees have a smaller branch outlet for distributing flow.

TypeEqual/Red

UseBranching

Pipe Reducers

Connects different pipe sizes. Concentric aligns centerlines (vertical runs), while Eccentric has a flat side (horizontal pump suction).

Pipe End Cap

Welded to the open end of a pipe to seal it permanently. Available in elliptical or hemi-spherical shapes for high-pressure durability.

FuncSealing

ShapeEllipsoid

Stub End

Used with a Lap Joint Flange. The stub is welded to the pipe, while the flange remains loose behind it, allowing easy bolt alignment.
