What is the difference between SCH40 and SCH80?
Which industries are SCH40 and SCH80 suitable for?

Comparing Sch40 and Sch80:
1.SCH80 will have thciker walls than SCH40.
2.SCH80 can withstand more pressure than SCH40.
3.Between Sch 40 and Sch 80 there has a difference of inner diameter.
4.SCH 40 and 80 often have a different color that is used to distinctly identify them.
Due to the greater wall thickness of Schedule 80 plumbing, it is collectively understood to be stronger and more resistant than its Sch 40 counterpart. Plumbing applications that encounter increased pressure stress, mechanical strains, and/or chemical interactions often benefit from the use of a greater pipe schedule for the parts.This is not to say Sch 80 is the best option simply because an application will transit liquids under pressure or handle chemicals. Rather, plumbing applications are extremely specific, especially those involving chemicals, and what is the best choice -- Sch 40 or Sch 80 -- will be an educated decision that considers the full variables of the pipe's intended use. If Sch 40 is acceptably rated for the operational conditions of the scenario, one can save both piping material and associated costs by choosing to use Sch40 over Sch 80 plumbing.
