COLOR OPTIONS
Hose shall be made from 100% high tenacity synthetic polyester yarn, circularly woven and completely protected by a through-the-weave extruded PVC/Nitrile rubber (30%/70%), forming a single homogeneous construction without the use of glues or adhesives of any type. MaTex Nitrex shall have a thin rib for standard Nitrex construction and a heavy rib for HD version to aid abrasion resistance. Hose will meet or exceed requirements of NFPA 1961 (1960) for abrasion resistance. Hose shall carry a 10-year written warranty against defects in materials and workmanship. Materials used in construction of the hose shall be new, unused and not less the the quality conforming to modern engineering and manufacturing practices. Materials shall be free of defects and suitable for the service intended.
The tensile strength of the lining and cover shall not be less than 1200 psi with an ultimate elongation of 400%. The tensile strength and ultimate elongation of the vulcanized rubber compound which has been subjected to the action of oxygen at a pressure of 300 psi (+/-10psi) and a temperature of 158F (+/-18F) for a period of 96 hours shall retain 60% of its originally stated properties.
Hose shall withstand 10,000 cycles on the Taber Abrasion Machine (H-22 Wheel: 0.5KG) without exposing the liner. Hose manufacturer on request will supply written warranties that hose meets a minimum 10,000 cycles. Other abrasion test results (UL, DIN, etc.) shall be supplied on request of purchaser.
Hose shall have a capability of use down to -65F. Hose shall have no apparent damage to cover, reinforcement, or lining when subjected to the following cold flexibility test: A 50’ length of dry hose is to be firmly coiled and placed in a cold box at -65F for a duration of 24 hours. Immediately after removal of the hose from the box, hose should be uncoiled and laid out by one operator.
A 3-foot sample of hose chosen at random shall stand without failure a hydrostatic pressure of 1500 psi while lying straight or curved on a 27” radius. Retention of the coupling to the hose shall equal or exceed the burst pressure.
The hose, when subjected to a static pressure of 100 psi, shall be capable of withstanding a surface temperature of 1200F for a minimum of one minute without rupture or damage to the synthetic reinforcement in accordance with British Hot Cube Test.
Hose shall show no visible signs of cracking to the lining or cover when tested in accordance to ASTM D518 Procedure B (100 pphm/118F/70 hours).
Short-term exposure to sea water and contamination by most chemical substances, including hydrocarbons, oils, alkalis, acids, and greases shall have no effect on the short- or long-term performance of the hose.
WARRANTY INFORMATION
The hose furnished under the terms of this proposal has a potential service life of 10 years barring mistreatment or accidental damage that would render the hose unfit for service. MaTex warrants the hose to be free from defects in materials and workmanship for a period of ten years. The warranty shall provide for the repair or replacement of hose and couplings proven to have failed due to faulty material or workmanship.
