King PipeGrade® is a PE 100 special black polyethylene material for the pipe industry. It is the product of a proprietary process called K-Stran™, the most advanced manufacturing process for superior flatness and consistency up to 1-1/2” thick. It is also available in compression mold greater than 1” through 4” thick, and extrusion mold from 2-1/2” up to 12” thick. Custom mold sizes available. King PipeGrade® has a smooth black finish on both sides of sheet. It displays improved performance characteristics in a variety of industrial applications. King PipeGrade® is chemical resistant, UV stabilized, and ideal for use in demanding outdoor applications from pipe flanges and fittings to pipe end caps. The polymer sheet will not rust, corrode or rot like traditional pipe products and is easy to fabricate and weld using thermoplastic welding equipment.

King PipeGrade® is compliant to ASTM 3350 as a standard material. ASTM 3350/4710 PE 100 is completely compatible and 100% interchangeable for use in applications that presently use ASTM 3608 – PE 80 material. King PipeGrade® is FDA and NSF Standard 14 certified and complies with ANSI/NSF Standard 61 to be used in potable water piping systems.

PE 100 tends to have a higher hydrostatic design basis (HDB) than other resins but most significantly in the notched tensile/slow crack PENT test which is > 10,000 hours vs. 100-200 hours for others.

50 – 100 years service life per ISO CRS 10 MPa @ 20º C.
