Design

All polyethylene fittings manufactured and distributed by Hawkeye Industries Inc are fully pressure rated. Because mitred fu-sions reduce the pressure rating of a fitting (‘de-rate’), Hawkeye increases the wall thickness to maintain the pressure rating of the fitting. The wall thickness can be increased by either using a larger OD of pipe with a low SDR and maintain the design ID (ID Control) or use the same size pipe and decrease the SDR in the region of the fusion (Non-ID Control). Injection molded fittings, as they do not have mitred fusions, maintain the pressure rating without an increase in wall thickness.

Flexibility

Fabricated fittings, including y-laterals, tees, elbows, flange adapters are available in sizes from 2 NPS to 16 NPS and in DRs 5, 6.3, 7.3, 9, 10, 11, 13.5, 17 and 21, depending on size. Molded fittings are available from 2 NPS to 12 NPS, in DRs 7, 9, 11, 13.5, 17. Fabricated y-laterals and tees can have different sized branches than mains, call us for more information.

Construction

Fabricated and molded fittings are offered in PE 100 / PE4710 standard, with PE3408 available as an option. For fabricated fit-tings, such as y-laterals, tees and multi-segment elbows, Hawkeye uses the mitred fusion joint method, as opposed to sidewall fusion, for strong, consistent and structurally sound construction. Ball Valves Hawkeye carries polyethylene ball valves in 2, 3 and 4 NPS SDR 11 sizes. Call us for availability of other sizes.
