About Better Flange

Flange Types

Better Flange is a reference for people who build, maintain and inspect bolted pipe joints.

Who reads it

Pipefitters and mechanics who want a quick refresher. Maintenance planners writing job packs. Young engineers meeting flange tables for the first time. Plant owners trying to work out why the same joint leaks after every turnaround.

What we cover

  • Flange types, facings and pressure classes
  • Gasket materials and how to match them to service
  • Bolting: studs, nuts, lubrication and tightening sequence
  • Inspection, leak causes and simple fixes

How we write

Short pages. One idea at a time. Practical over theoretical. Where a design standard governs the answer, we say so and point you to it rather than guessing at the numbers. This is general guidance; your site procedures, the equipment manufacturer and the applicable code always come first.
