Flex-Weld, Inc. uses interlock hose as a component for engineered hose assemblies and also to be sold separately as bulk hose.
Interlock hose is produced by spirally winding a precision-slit metal strip so that the edges interlock to form a seamless length in a configuration, size, and type custom-designed for each specific application. Packing materials can be introduced during the manufacturing process to form a leakage barrier in the interlock zone.
The interlock hose can be manufactured from a variety of materials including aluminum, galvanized steel, stainless steel, Monel, Inconel, or bronze, depending on the application. Consult our engineers for questions concerning material compatibilities and selection.
Inside diameters span a wide range from 1/8" to 24". At the small diameter end of the spectrum, a typical end use would be for capillary and telephone cable hose. By contrast, the largest diameter interlock hoses are frequently used for unloading grain and sawdust. Flexibility can range from stiff to floppy while at the same time, weight can range from heavy to light, depending on the required usage of the product.
Although interlock hose can be used stand-alone with its own welded or brazed-on fittings, it is also used as a liner for high flow velocity corrugated hose assemblies or as an outer guard for braided corrugated hose assembly external protection. The inside of this our interlock brochure, accessed through the link below, provides some examples of standard stock interlock hose configurations.Product Literature
