Piping Engineer Interview Questions and Answers for Freshers

The ASME code for process piping is ASME B31.3

• ASME B31.3 is the code for process piping design, construction, and inspection

• It covers materials, fabrication, assembly, erection, testing, and maintenance

• The code also includes requirements for pressure testing, welding, and nondestructive examination

• ASME B31.3 is widely used in the oil and gas, chemical, and power industries

Pipe thickness can be calculated using various methods such as ASME B31.3 code, API 570 code, and engineering calculations.

• Calculate based on pressure and temperature requirements specified in ASME B31.3 code

• Use API 570 code for calculating minimum required thickness for piping in-service

• Perform engineering calculations considering factors like material properties, design pressure, and corrosion allowance

• Consider additional factors such as external loads, thermal expansion, a...read more

ASME B31.3 is the code for pipes made of stainless steel (SS).

• ASME B31.3 is the code for process piping made of SS.

• It covers design, materials, fabrication, testing, and inspection.

• It is widely used in the chemical, petroleum, and pharmaceutical industries.

• Other codes for SS pipes include ASTM A312, ASTM A358, and ASTM A409.

Support-4 refers to a type of pipe support used in piping systems to provide stability and prevent movement.

• Support-4 is a specific type of pipe support used in piping systems.

• It is designed to provide stability and prevent movement of the pipe.

• Support-4 is typically used in locations where additional support is needed to prevent sagging or shifting of the pipe.

• Examples of Support-4 include clamps, hangers, and brackets that are used to secure the pipe in place.

Corrosion on piping is a common problem that can lead to leaks, failures, and safety hazards.

• Corrosion can be caused by various factors such as moisture, chemicals, and high temperatures.

• Preventive measures include regular inspections, coating the pipes, and using corrosion-resistant materials.

• Corrosion can be detected through visual inspection, ultrasonic testing, and corrosion monitoring.

• If corrosion is detected, it should be addressed immediately to prevent further damage ...read more
