Longman 450 is one type of through-the-weave Nitrile Rubber (NBR) covered
hoses. Longman 450 hoses shall be made from 100% high tenacity synthetic yarn
circular woven and completely, totally embedded in the NBR/PVC
compound, excellent protected against mechanical damage, forming a
single homogenous construction without the use of any glues or
adhesives of any type.
NBR compound is composed of NBR and PVC. High percentage of NBR content contributes to better abrasion-resistance.
Lining Properties:
a. Ultimate Tensile Strength:
Tensile strength of the lining and cover shall not be less than
1500 psi (10,500 kpa ).
b. Ultimate Elongation:
400% minimum.
c. Accelerated Aging Test
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 +/- 10 psi , (2100kpa +/- 70kpa) and
temperature of 70 degrees centigrade +/-1 degree centigrade (158 F
+/- 18 F ) for a period of 96 hours shall be , greater than 60% of
the original properties stated.
Application:
Suitable for irrigation, washdown, water discharge, Drainage pumps, Pumping of sludge and liquid fertilizers, Temporary installations (by-passes) etc.
*Not recommended or approved for fire fighting or frac water transferring.
Recommended for Industrial Water Discharge Solution.
Comparable to
Oroflex 10 of Tipsa, Superflow of Key, etc.
