Static Equipment Interview Questions -

A failure mechanism that affects Austenitic Stainless Steels (304, 316) . It requires three factors:

What are the common types of shell and tube heat exchangers? Be prepared to discuss fixed-tubesheet (cost-effective for clean fluids), (allows thermal expansion), and floating head What is secondary stress?

The pressure used in the design formulas to calculate component thicknesses. It includes a safety margin above the maximum operating pressure to account for process surges.

What is the difference between a 2:1 Ellipsoidal head and a Torispherical head? static equipment interview questions

“Have you seen a pneumatic test gone wrong?” Best answer: Not personally — because I follow the code. But case studies show vessel doors becoming missiles.

What is the difference between RT (Radiographic Testing) and UT (Ultrasonic Testing)?

Since static equipment sits in one place for decades, material degradation is the primary enemy. A failure mechanism that affects Austenitic Stainless Steels

A hydrostatic test is a pressure test performed by filling the equipment with water and pressurizing it to check for leaks and structural strength. According to ASME Section VIII Div 1, the standard hydrostatic test pressure is:

Viscous fluids (to increase turbulence and heat transfer rates), condensing or boiling fluids, and fluids with low allowable pressure drops. 3. Storage Tanks (API 650 & API 620)

Q2: What is the difference between Design Pressure, Operating Pressure, and MAWP? The pressure used in the design formulas to

It allows for independent movement between the tube bundle and the shell, which prevents stress caused by thermal expansion When is an expansion bellow required in a heat exchanger?

). This creates high internal gas pressure, causing internal blistering and planar cracking.

You should explain that both govern the design of pressure vessels, but they differ in philosophy. Division 1 uses a "design by rule" approach. It is prescriptive, offering specific formulas for thickness based on a safety factor (historically 3.5 on tensile strength). It is generally easier to apply but results in thicker, heavier vessels.

Good luck with your interview. Stay static, stay strong.
