Custom-Engineered Material Transfer Hoses

Custom-engineered, made-to-order, material transfer hoses are often required in sand & gravel, phosphate, ore mining, slurry handling, and other large bore suction and discharge applications. We can custom build hoses up to 42″ ID built for almost any application, including built to superior flexibility, built to withstand abrasion or heat, or designed for greater chemical compatibility.

Defining answers to the acronym STAMPED (Size, Temperature, Application, Material, Pressure, Ends, Delivery) will help in the proper selection of hose and fittings to reduce the chance of a failure from a misapplication. Serious damage and/or injury may occur if a hose or fitting is used in an application other than what it is designed for. It must also be noted that hose will degrade over time and is not designed for permanent piping applications, especially when it will not be subject to routine testing and inspection.

NL8250 is a made-to-order, high quality, heavy duty material handling hose available with a variety of "built-on" end styles (built-on rubber lined flanges, built-in nipples, floating flanges, rubber lined groove ends, etc.). It can have a variety of tube thickness’s as well as varying pressure ratings and lengths (larger sizes of this hose -- if a hard wall hose -- must be shipped in straight lengths). It can be used in conjunction with rubber lined pipe or cast iron pipes where minimal bends are required or where the inherent flexibility of a durable rubber hose is required. Listed below are a few of the configurations.

Special Note: Service life of material handling hoses may vary depending on the operating conditions, hours of use, and the product being conveyed. Always rotate the hose regularly for even wear and inspect the tube for degradation before use.

Built-In Nipple End

The hose end is integrally built around and bonded to the nipple body. The hose reinforced materials are also anchored to the nipple. The nipples used are generally fabricated from pipe. Nipples made from standard pipe will be full bore only when pipe 12” and under is used since nominal pipe sizes over 12” are described by pipe OD and not ID.

Rubber Beaded End

A flared bell shape, molded as an integral part of the hose. The reinforcing fabric of the hose body is extended beyond the straight portion of the hose and anchored around a circular steel reinforcing ring. A reattachable split flange (steel or S.S.) is placed behind the rubber bead to act as a metal bearing surface for bolt heads and nuts. Bolts used to connect mating flanges pass over the outside diameter of the beaded end.

Integral Rubber Flanged End

Shaped similar to a metal pipe flange. It is molded as an integral part of the hose with the tube, fabric reinforcement (not wire), and cover extending to the outside diameter of the rubber flange. The rubber flange has holes to match customer requirements. In addition, solid metal “backup” rings (drilled to match the rubber flange holes) are always placed behind the rubber flange to provide a metal bearing surface for bolt heads and nuts.
