Quilon Real Industries Interview Questions, Process, and Tips

The degree for bevel end in piping engineering refers to the angle at which the end of a pipe is cut.

• The degree for bevel end is typically specified in piping engineering drawings or specifications.

• Common bevel angles include 30 degrees, 37.5 degrees, and 45 degrees.

• The bevel angle is important for proper fit-up and welding of pipes.

• Different bevel angles may be used based on the pipe material, wall thickness, and weld...read more

ASME B31.3 is the code used for carbon steel (CS) piping.

• ASME B31.3 is the American Society of Mechanical Engineers code for process piping.

• It provides guidelines for the design, fabrication, inspection, and testing of CS piping systems.

• CS refers to carbon steel, which is a common material used in piping construction.

• ASME B31.3 covers various aspects such as materials, pressure design, welding, and nondestructive exami...read more

Post heating temperature is the temperature at which a material is heated after welding to relieve residual stresses and prevent cracking.

• Post heating temperature is typically lower than the preheating temperature used before welding.

• It is commonly used in welding processes such as pipeline construction and pressure vessel fabrication.

• The purpose of post heating is to slow down the cooling rate of the welded material, ...read more

There are several types of flanges used in piping systems.

• Weld Neck Flange

• Slip-On Flange

• Socket Weld Flange

• Threaded Flange

• Blind Flange

• Lap Joint Flange

• Orifice Flange

• Expander Flange

• Reducing Flange

• Long Weld Neck Flange

There are several types of reducers used in piping systems.

• Reducers are used to connect pipes of different sizes.

• Common types of reducers include concentric reducers and eccentric reducers.

• Concentric reducers have a symmetrical shape and maintain the centerline of the pipe.

• Eccentric reducers have an offset shape and are used when there is a need to maintain the same level.

• Other types of reducers include reducing tees a
