United Company Interview Questions and Answers

7QC tools are a set of quality control tools used for process improvement and problem-solving in quality management.

• Check sheets: Used to collect and analyze data in a systematic way.

• Histograms: Used to show frequency distribution of a process.

• Pareto charts: Helps identify the most significant factors contributing to a problem.

• Cause-and-effect diagrams: Used to identify and analyze potential causes of a problem.

• Scatter diagrams: Used to show the relationship between two varia...read more

CPK is a statistical measure used to assess the capability of a process to produce output within specification limits.

• CPK is calculated using the formula: CPK = (USL - LSL) / (6 * standard deviation)

• A CPK value greater than 1 indicates that the process is capable of producing within specification limits

• A CPK value less than 1 indicates that the process may not be capable of consistently producing within specification limits

Ra in roughness tester is the average roughness value of the surface profile within a specified sampling length.

• Ra is a parameter used to quantify the roughness of a surface.

• It is calculated as the arithmetic average of the absolute values of the profile heights over the evaluation length.

• Ra provides a measure of the deviation of the surface profile from the mean line.

• It is commonly used in industries such as manufacturing and engineering to assess surface finish quality.

The 8D methodology is a problem-solving approach used in quality management to identify, correct, and prevent recurring problems.

• The 8D methodology consists of 8 steps: D0 - Plan, D1 - Team Formation, D2 - Problem Description, D3 - Interim Containment Action, D4 - Root Cause Analysis, D5 - Permanent Corrective Action, D6 - Prevent Recurrence, D7 - Recognize Team Effort, D8 - Closure and Team Disbandment

• It is commonly used in industries such as automotive, aerospace, and manuf...read more

Yes, industrial valves types include gate valves, globe valves, ball valves, butterfly valves, and check valves.

• Gate valves are used to control the flow of liquids by opening or closing the gate.

• Globe valves regulate flow by moving a disc up and down against the flow.

• Ball valves have a spherical closure unit to control flow.

• Butterfly valves have a disc that rotates to regulate flow.

• Check valves allow flow in one direction only to prevent backflow.

A steam trap is a device used to discharge condensate and non-condensable gases from a steam system while preventing steam from escaping.

• Steam traps help improve energy efficiency by removing condensate from steam systems.

• They prevent damage to equipment by ensuring that only steam enters the system.

• There are different types of steam traps such as mechanical, thermodynamic, and thermostatic traps.

• Examples of steam trap manufacturers include Spirax Sarco, Armstrong Internation...read more

Valves in steam applications control the flow and pressure of steam to ensure safe and efficient operation.

• Regulate steam flow and pressure

• Prevent steam leaks and ensure safety

• Control temperature and maintain system efficiency

• Examples: gate valves, globe valves, ball valves, check valves
