Q1. What are the specifications of the code, and what is the essential knowledge required for applying to the relevant department?

Ans.

The specifications of the code and essential knowledge required for applying to the relevant department in Manager - Piping role.

The specifications of the code typically refer to industry standards such as ASME B31.3 for piping design and construction.
Essential knowledge required includes understanding of piping materials, stress analysis, and piping layout design.
Familiarity with piping software like AutoCAD, Caesar II, and PDMS is often necessary.
Knowledge of relevant codes...read more

Ans.

Pipe thickness calculation as per ASME b31.3 and well head piping.

Pipe thickness calculation involves determining the required wall thickness to withstand the internal pressure and external loads.
ASME B31.3 provides guidelines for process piping while wellhead piping requires additional considerations such as corrosion and erosion.
Factors such as material properties, design temperature, and pressure rating are also taken into account.
Various methods such as the Barlow's formu...read more

Ans.

Killed steel is a type of steel that has been deoxidized with an agent such as silicon or aluminum to prevent gas pockets and improve its properties.

Killed steel is commonly used in the production of high-strength steel products such as structural steel, shipbuilding steel, and pipeline steel.
The deoxidizing agent reacts with the oxygen and other impurities in the molten steel to form a slag, which is then removed from the surface of the steel.
This process helps to prevent ga...read more

Ans.

Stress factor in piping is calculated using formulas based on material properties, operating conditions, and design codes.

Calculate stress due to internal pressure, external loads, thermal expansion, etc.
Consider material properties like yield strength, modulus of elasticity, and temperature limits.
Refer to design codes like ASME B31.3 for guidelines on stress calculations.
Use software tools like CAESAR II for accurate stress analysis.
Ensure compliance with safety standards t...read more

Ans.

Productivity norms in Piping refer to the expected output or efficiency levels for piping work.

Productivity norms are typically set based on industry standards and past project data.
Factors influencing productivity norms in piping include complexity of design, availability of resources, and skill level of workers.
For example, a productivity norm for welding joints in a certain type of piping may be set at 10 joints per hour based on historical data.
Regular monitoring and adju...read more
