ABRASIVE MATERIAL HOSE

Different technologies can achieve parallel results in hose manufacturing, often resulting in a confusing assortment of products to choose from. This is true for material handling hoses. Early products were heavy rubber hoses with natural rubber tubes for extreme applications (see G741 and G743). Then came thermoplastic rubber combined with PVC produced hoses such as G1340C and G1341C that offer lighter weight and a more economic solution. Most recently, urethane lined hoses such as G1741, G1741AMPH and G1741UBK combine the lightweight characteristics of PVC with the extreme abrasion resistance of urethane.

G1741… URETHANE BULK MATERIAL

Construction : Clear polyurethane tube fused to high molecu lar-weight flexible PVC, and supported by a rigid PVC helix. Interior : Smooth, clear, ultra-abrasion resistant polyure thane. Exterior : Blue, convoluted, abrasion and weather resistant, high molecular-weight PVC compound. Temperature Range : -40°C (-40°F) to 65°C (150°F). G1741 is for suction, discharge, and pneumatic transfer of abrasive materials. Urethane Bulk Material is recommended for sand and shot blast recovery lines, grain handling, roof rock cleaning, and milling machine metal recovery lines. This hose is much lighter than conventional rubber hoses because of its thermoplastic construction, yet remains flexible in the cold when general PVC hoses become too stiff to use.

G1741AMPH… AMPHIBIAN HOSE

Construction : Clear polyurethane tube fused to high molecu lar-weight flexible PVC, and supported by a rigid PVC helix. Interior : Abrasion, oil, and water resistant. Exterior : Black, convoluted, abrasion and weather resistant, high molecular-weight PVC compound. Temperature Range : -40°C (-40°F) to 65°C (150°F). The thick urethane liner in G1741AMPH is specially compounded for wet service, making this hose excellent for sewer truck and hydro excavation applications. Urethane is not only very abrasion resistant, but also resists most animal and petroleum based oils. As a result, this product is useful in a variety of dry and wet material handling applications. In addition, the cover is compounded to dissipate static electricity for added safety.
