D. R. John's Lab Pharma Private Limited Interview Questions, Process, and Tips

Examine dimensions, materials, fittings, supports, and routing in isometric drawings.

• Check dimensions to ensure proper fit and clearance

• Verify materials specified for construction

• Review fittings for correct type and size

• Confirm supports are in place for proper installation

• Analyze routing to ensure efficient flow and accessibility

• Example: Checking pipe diameter for compatibility with system requirements

Documents required for piping modeling include P&IDs, equipment datasheets, piping specifications, and 3D model standards.

• Piping and Instrumentation Diagrams (P&IDs) provide the overall layout and design of the piping system.

• Equipment datasheets contain information about the equipment to be connected to the piping system.

• Piping specifications outline the materials, sizes, and standards to be used for the piping...read more

P&ID shows detailed piping and instrumentation information, while PFD shows overall process flow.

• P&ID includes detailed information on piping, valves, instruments, equipment, and control systems.

• PFD provides an overview of the entire process flow, showing major equipment and key control loops.

• P&ID is used for detailed engineering design and implementation, while PFD is used for process understanding and ana...read more

Key deliverables expected from a piping engineer include design, analysis, documentation, and project coordination.

• Designing piping systems based on project requirements and specifications

• Performing stress analysis to ensure structural integrity

• Creating detailed drawings and documentation for construction

• Coordinating with other engineering disciplines and stakeholders

• Ensuring compliance with industry standards and regu

I would approach creating a pump piping layout by considering factors like pump type, flow rate, pressure requirements, and space constraints.

• Identify the type of pump being used (centrifugal, reciprocating, etc.)

• Determine the required flow rate and pressure for the system

• Consider the layout of existing piping and equipment to optimize space utilization

• Ensure proper support and anchoring of the piping to prevent vibrat...read more

The north sign in isometric drawings is important for orientation and ensuring consistency in the drawing.

• The north sign helps in determining the direction of the drawing, ensuring that it is correctly oriented.

• It helps in maintaining consistency in the drawing, especially when multiple sheets are involved.

• It assists in understanding the spatial relationship between different components in the drawing.

• Without the north...read more
