Hose – Specifications
Aquaman Blue & Wasteline Green
Sizes 1” – 12”
Quality: The Blue portable pipeline supplied under this specification shall be a premium quality, extruded thru-the-weave potable water transport pipeline. The portable pipeline shall be manufactured using only certified materials and shall have as a minimum an International and Domestic NSF-61 certifications on the finished product. All products shall have a minimum “Safety Factor”(SF) of 2 to 1, working pressure to burst pressure. A 2 to 1 (SF) will insure the safety and reliability of the portable pipeline when used in an “Emergency” or during repetitive maintenance operations.
Service Life: The portable pipeline furnished under the terms of this proposal shall have a potential service life of 10 years barring mistreatment or accidental damage that would render it unfit for service. Upon delivery, the Portable Pipeline System shall be in first class condition and have a one year warranty against defects in workmanship and materials. The supplier shall provide replacement of any product as may be defective without any charge to the Utility Department.
Quality Assurance: Quality management procedures shall regulate all areas in the manufacturing process including twisting of yarns, weaving of jackets and extruding of finished product. Current calibrations on all test apparatuses traceable to the National Institute of Standards and Technology (NIST) shall be maintained at point of manufacturing.
Certifications: All products shall meet the requirements of an International and Domestic Standard for the transport of Potable water. Pursuant to those standards, all products meeting either the German KTW Class C for temporary service, British WRC (BS-6920), National Sanitation Foundation. NSF-61 shall be marked on the finished product. Products marked with “For Potable Water Only” or “Approved for Potable Water” are not acceptable for use in the transport of drinking water.
Manufacturing Process: The portable pipeline shall be manufactured using a thru-the-weave extrusion process. A woven jacket shall be completely encapsulated with a polyurethane cover and lining. The extrusion process shall produce a one-piece construction that has integrity between cover and liner. Integrity of pillar adhesion through the interstitial spaces in the woven jacket shall be determined by applying weight between lining and jacket and cover and jacket of not less than 4.45 decanewtons (daN). Assembling of the cover, lining and woven jacket shall be controlled to reduce overall weight, compactness and bend/kink radius.
Jackets: Reinforcement material shall be a single ply of spiral woven jacket of polyester yarn. The jacket
shall be evenly and firmly woven, free from unsightly defects, dirt, knots, limps, and irregularities of twist that might affect the serviceability of the finished product.
Cover & Lining: The polyurethane material used in the construction of the cover and lining shall be a
single ply extrusion of polyether urethane polymer. The polyurethane shall naturally resist hydrolysis, ozone and oxidation. No reclaimed material shall be acceptable. All component material making up the “Cover / Lining” shall meet the standards for Potable Water applications.
Ozone Resistance: Exterior cover specimens shall be subjected to ASTM D 1149-91 “Standard Test
Method for Rubber Deterioration – Surface Ozone Cracking in a Chamber”. Specimens shall be prepared in accordance with ASTM D-518-86, “Standard Test Method for Rubber Deterioration – Surface Cracking”, Procedure C and shall be elongated 15%. After conditioning for 24 hours in an ozone free atmosphere, the mounted specimens shall be exposed for 336 hours @ 104°±F to an atmosphere containing 50 pphm ± of ozone. There shall be no appearance of cracking / crazing when viewed under a 7 X magnifying glass any time during or at the end of 336 hrs.
Tensile Strength/Ultimate Elongation after Water Immersion: Tensile strength and ultimate elongation after water immersion shall be determined in accordance with ASTM D-471. The immersion test shall be performed in accordance with ASTM D-471 utilizing water as a test fluid. One specimen shall be subjected to water immersion for 14 days at 23°C. When tested as specified tensile strength of the tube and cover >14 days water immersion shall be at least 40% of the tensile strength obtained before immersion and shall be at least 500 psi. Tensile strength >42 days immersion shall be at least 25% of tensile strength before immersion and shall be at least 200 psi. When tested as specified the ultimate elongation after 14 days of immersion shall not be < 40% of the original elongation obtained before immersion. Ultimate elongation after 42 days shall not be < 25% of the original elongation obtained before immersion.
Low Temperature Flexibility: The Portable Pipeline shall be capable of performing in cold temperature. Test for low temperature flexibility shall be made in accordance with ASTM D-1053. Low temperature test shall be determined after samples have been conditioned 7 days @ -25°F. Leakage shall be cause for rejection.
Abrasion: Portable Pipeline shall be tested using a Taber Abrasion device in accordance with ASTM D3389 method A by using an abrasion wheel H-22 having neither additional weight nor counterweight applied to the specimen holder. Specimen should withstand at least 250,000 cycles without any jacket exposure.
