Types of pipes used in piping include steel, copper, PVC, and HDPE.

• Steel pipes: commonly used for high-pressure applications

• Copper pipes: used for water supply lines

• PVC pipes: lightweight and easy to install, commonly used for drainage systems

• HDPE pipes: high-density polyethylene pipes used for underground gas and water lines

Bevel angle of piping refers to the angle formed between the prepared edge of the pipe and a plane perpendicular to the pipe axis.

• Bevel angle is typically specified in degrees, such as 30° or 45°.

• It is important for welding processes to ensure proper fit-up and joint strength.

• Different bevel angles may be required based on the material being used and the welding procedure being employed.
