The depth required for IGL gas laying depends on various factors such as soil type, traffic load, and depth of other utilities.

• The depth should be sufficient to prevent damage from external factors such as traffic load and soil type.

• The depth should also be deep enough to avoid interference with other utilities.

• The depth requirement may vary depending on the location and local regulations.

• For example, in Delhi, the minimum depth requirement for IGL gas laying is 1.2 meters.

Valves are devices used to control the flow of fluids or gases in a system.

• Gate valve: used to start or stop the flow of fluid by lifting or lowering a gate

• Ball valve: uses a rotating ball with a hole to control the flow

• Check valve: allows flow in one direction and prevents backflow

• Globe valve: controls flow by raising or lowering a disc against the flow

• Butterfly valve: uses a disc to control flow by rotating it

QAP, WPS, and DFT are important documents used in inspection engineering.

• QAP stands for Quality Assurance Plan, which outlines the procedures and requirements for ensuring quality in a project or process.

• WPS stands for Welding Procedure Specification, which provides detailed instructions for performing welding operations.

• DFT stands for Dry Film Thickness, which refers to the thickness of a coating or paint applied to a surface.

• QAP ensures that quality standards are met throug...read more
