Flange Management-Comprehensive Flange Guidance

Example

Choosing the right type of flange (e.g., weld neck, slip-on, threaded) and material (carbon steel, stainless steel, alloy) based on the pressure rating, temperature, and chemical compatibility of the application.

Scenario

In a chemical plant, selecting a nickel-alloy flange for a high-temperature sulfuric acid line to ensure compatibility and durability under severe service conditions.

Example

Detailed steps for correct flange alignment, gasket placement, and bolt tightening using specific tools like torque wrenches to achieve optimal sealing and prevent leaks.

Scenario

During the assembly of a new section of pipeline in a natural gas facility, technicians follow precise bolt tightening sequences to ensure even load distribution and prevent flange deformation.

Example

Regular scheduled checks for leaks, bolt tension, and overall flange condition, including non-destructive testing techniques like ultrasonic testing to detect flaws or degradation.

Scenario

In a power generation plant, routine shutdowns include flange inspections to verify integrity and replace worn gaskets or corroded bolts before they lead to failures.
