1D 1.5D 3D 5D Elbow

A 90d elbow refers to an elbow with a bending angle of 90 degrees. It is typically used to change the direction of flow in a piping system.

An 8D bend refers to a bend with a bending radius of eight times the nominal diameter of the pipe it is being connected to. For example, an 8D bend for a 4-inch pipe would have a bending radius of 32 inches.

A 6D elbow refers to an elbow with a bending radius of six times the nominal diameter of the pipe it is being connected to. For example, a 6D elbow for a 4-inch pipe would have a bending radius of 24 inches.

A 5D elbow refers to an elbow with a bending radius of five times the nominal diameter of the pipe it is being connected to. For example, a 5D elbow for a 4-inch pipe would have a bending radius of 20 inches.

A 1 D bend refers to a bend with a bending radius equal to the nominal diameter of the pipe it is being connected to. For example, a 1 D bend for a 4-inch pipe would have a bending radius of 4 inches.

An elbow 3D refers to an elbow with a bending radius of three times the nominal diameter of the pipe it is being connected to. For example, a 3D elbow for a 4-inch pipe would have a bending radius of 12 inches.

1.5 D in elbow refers to an elbow with a bending radius of 1.5 times the nominal diameter of the pipe it is being connected to. For example, a 1.5 D elbow for a 4-inch pipe would have a bending radius of 6 inches.
