1. Manufacturing Process of Bi Metal Clad elbow:
Bi Metal Clad elbow are cast with mold vanishing vacuum suction casting cladding process. Outer of straight pipe is common steel pipe, cladding realized by forming high chromium lining via centrifugal forming technique. Outer of bend uses hot-bending bend and lining is cast with high-chromium cast iron. Bends and other profile sections can be cladded in whole and this process has changed the traditional practice to fabricate bend and other profile sections by drawing polyline without changing flow pattern of material inside piping,greatly reducing conveyance resistance of material.

2. Advantages Compared with Traditional Wear Resistant

Alloy Cast Iron, Alloy Cast Steel, General Clad Steel Pipe and Cast Stone Pipe:

1. Good wear-resistance, giving full play to wear-resistance of high chromium cast iron.
2. Withstanding high pressure:
Bimetal cladding pipe and bend can be used for any pressure rating. Close bonding of outer and lining by adopting special process make cladding interlayer molten-joint to ensure reliable operation.
3. Good mechanical impact and thermal impact resistance property.
4. Convenient in connection for installation:
Bimetal cladding pipe and bend can be cut and welded as you like.

An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.

Most elbows are available in short radius or long radius variants. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

Elbows are categorized based on various design features as below:
