ELBOWS

An elbow is a connecting piece with a specific bending radius used to connect two pipes of the same diameter. A distinction is made between different bending radii (Long Radius, Short Radius, R=3D, R=5D) and segments (45°, 90°, 180°).

REDUCERS

A reducer is a connecting piece that forms the transition between two pipes of different diameters. Reducers are available as an ecentric or concentric fitting.

TEES

TEES

A tee is a connecting piece that enables an existing connection to branch-off. It connects three pipes of the same or different diameters. We differentiate between equal and reduced tees.

WELDOLETS

Weldolet is a branch butt weld connection fitting that is adhered to outlet pipe to minimizes stress concentrations. And it provides overall reinforcement. Normally it has the same or a higher schedule than the run pipe schedule, and offers a variety of forged material grades, such as ASTM A105, A350, A182 etc.

FORGED FITTINGS

Forged Pipe Fittings (Socket Weld and Threaded) are made in accordance to ASME (American Society of Mechanical Engineers) B16.11, MSS-SP-79\ 83\ 95\97 and BS3799 standards, and are used to connect nominal bore schedule pipes and pipelines.

PIPE BENDS

Bend pipes come in all types of radious, including 3D bends, 4D bends, 5D bends, 8D bends and 10D bends. The radius in 5D bends is five times the nominal diameter. With a 10-inch diameter pipe, the radius of the center line of the bend would be 50 inches.
