Hitek Engineering Services Project Engineer Interview Questions, Process, and Tips

MVWS and HVWS are fire fighting spray systems with different applications and effectiveness based on fire type and environment.

• MVWS (Medium Velocity Water Spray) systems use water sprays at medium velocities, effective for cooling and controlling fires.

• HVWS (High Velocity Water Spray) systems discharge water at high velocities, suitable for extinguishing large fires and protecting structures.

• MVWS is often used in indus...read more

Hydrotesting involves filling a system with water to check for leaks at a specified pressure, typically 1.5 times the design pressure.

• 1. Prepare the system by cleaning and inspecting it for any visible defects.

• 2. Fill the system with water, ensuring all air is purged from the lines.

• 3. Gradually increase the pressure to the test pressure, usually 1.5 times the maximum allowable working pressure (MAWP).

• 4. Maintain the te...read more

Welding procedure involves joining two materials together using heat and pressure.

• Select appropriate welding method based on materials being joined

• Prepare materials by cleaning and removing any contaminants

• Set up welding equipment and ensure proper safety measures are in place

• Weld materials together using the selected method

• Inspect the weld for quality and make any necessary adjustments

Welding consumables should be selected based on factors like base metal, welding process, mechanical properties required, and environmental conditions.

• Consider the type of base metal being welded

• Choose the appropriate welding process (e.g. MIG, TIG, stick)

• Determine the mechanical properties required for the weld joint

• Take into account the environmental conditions of the welding site

• Consult with welding engineers or sup
