All Hose Construction elements are exposed (including wire, if wire is used as a reinforcing member.). The hose always has the same inside diameter throughout. In the case of certain hand-built specifications having wire reinforcement, the wire and fabric reinforcement are not expose. All vertical spiral hoses is available only with plain ends. Horizontal spiral and wrapped ply machine built hose is furnished with plain ends unless otherwise specified in the price list.
The hose end is integrally built around and bonded to the nipple body. The hose reinforcing materials are also anchored to the nipple body. 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. Available only in hand-built hose construction.
Primarily used on petroleum, Oil Suction & Discharge, dock hose as an alternative to bulk it-in nipples. The steel (carbon or stainless) stem/coupling accommodates threaded, slip-on or welded flanged ends. Stem/coupling attached to hose with swaged steel ferrule over the cover.
The hose end is enlarged to accommodate the outside diameter of the shank of a fitting plus the depth of the shank. The helical wire is terminated at the enlarged end. The inside diameter of a "standard" enlarged end is the same dimension as the outside diameter of the same nominal pipe size.(Example-6" ID hose enlarged to 65/8" at the end, handles a 6"size pipe which has a 65/8"OD.) Normally used in hand-built hose constructions.
The Inside diameter and the outside diameter of the hose end are gradually tapered down to form a nozzle. The hose reinforcement is also extended to the end of the nozzle. A rubber end caps is then added to protect the reinforcement and properly shape the nozzle. This type of nozzle is available only in non-wise inserted horizontal spatial and wrapped ply machine-built hose.
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 reattach able split malleable iron flange is placed behind the rubber beaded 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. Normally used in hand-built hose constructions.
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. Available only in hand-built hose constructions.
The helical wire reinforcement is terminated several inches back from the end of the hose. When a hose has either a corrugated cover or tube or both, a soft end is generally used and always has a smooth inside diameter and outside diameter. Normally used in hand-built hose constructions.
