Wood Group Piping Designer Interview Questions and Answers

There are several types of gaskets used in piping, including spiral wound, ring joint, and sheet gaskets.

• Spiral wound gaskets are commonly used for high pressure and temperature applications.

• Ring joint gaskets are used in high pressure and high temperature applications, typically in oil and gas industries.

• Sheet gaskets are versatile and come in various materials such as rubber, cork, and graphite.

Isometric drawing is a 3D drawing technique used in piping to show a clear representation of piping layout.

• Isometric drawing is a type of 3D drawing that represents a 3D object in two dimensions.

• It is commonly used in piping to show the layout of pipes, fittings, and other components in a clear and detailed manner.

• Isometric drawings help in visualizing how components fit together and the overall layout of a piping syst...read more

Isometric drawings are 3D drawings that show a three-dimensional object in a two-dimensional format.

• Isometric drawings use three axes (x, y, z) to represent the object in 3D space.

• All three axes are equally angled from each other, typically at 120 degrees.

• Isometric drawings are commonly used in engineering and construction to visualize objects and structures.

• Examples of isometric drawings include piping layouts, archit

To work in oil and gas refinery, one must have a strong understanding of piping systems, safety regulations, and industry standards.

• Obtain a degree in engineering or a related field

• Gain experience through internships or entry-level positions

• Familiarize yourself with industry-specific software and tools

• Stay updated on safety regulations and best practices

• Develop strong communication and problem-solving skills

To work in oil and gas refinery erection plan, one must have knowledge of piping design, construction codes, safety regulations, and project management.

• Understand piping design principles and specifications

There are two main types of cranes: mobile cranes and tower cranes.

• Mobile cranes are versatile and can be easily moved from one location to another. They are commonly used for construction projects.

• Tower cranes are fixed to the ground and are often used for tall buildings or structures that require heavy lifting at great heights.

Expansion stress formula calculates the stress caused by thermal expansion or contraction.

• Expansion stress formula is given by: ΔL/L = αΔT, where ΔL is the change in length, L is the original length, α is the coefficient of thermal expansion, and ΔT is the change in temperature.

• The formula can be used to calculate the stress caused by thermal expansion or contraction in piping systems.

• The formula assumes that the mater...read more

Sustain stress formula calculates the maximum allowable stress for a given material under sustained loading.

• Sustain stress formula is used in piping stress analysis to determine the maximum allowable stress for a given material under sustained loading.

• The formula takes into account the material's yield strength, ultimate tensile strength, and safety factor.

• Sustain stress formula is expressed as S = (Sy/FS) + (Su/FS) * ...read more

Rack elevation and piping arrangement are crucial for efficient piping design. Distance between two pipes depends on the fluid being transported.

• Rack elevation should be considered while designing piping layout to avoid clashes and ensure proper support.

• Piping arrangement over rack should be designed to minimize stress on the rack and ensure easy maintenance.

• Distance between two pipes depends on the fluid being transpo...read more

I'm sorry, but I cannot answer that question as it is unclear what package and proof you are referring to.
