Description
HD piping is located specifically in demanding operating conditions within aerated high pressure pneumatic transportation systems. These are used within pneumatic transportation systems for strongly and moderately abrasive materials. HD piping is characteristic for the thickness of its materials due to quick wear and tear. HD elbows with interchangeable backings are used as well. HD piping is produced from Class 11 steel. They are regularly produced in sizes from 101.6 mm to 355.6 mm in diameter. The surface finish is executed as a primer layer of anti-corrosion paint; a specific surface coating or a surface treatment before the final surface finish can be agreed in advance.
