INTERLOCKED METAL HOSE


HOSE FUNDAMENTALS

Penflex interlocked metal hoses are made for a variety of specialized industrial applications and are available in a wide range of metals, styles and sizes. Interlocked hose is manufactured by helically winding preformed metal strip over a sizing mandrel and folding together the adjacent edges forming the interlocked convolutions. A packing material may be inserted into a preformed groove within the interlock to make the hose pressure tight or to minimize leakage. This packing forms a continuous gasket seal throughout the entire length of the hose. Flexibility is achieved through the sliding action which is provided by the slip-space within each interlocked convolution. The limits of axial elongation or compression are established when the convolutions are all fully opened or are all fully closed. Similarly, the minimum bend radius is achieved when the convolutions on the outside of the bend are fully opened, and those on the inside of the bend are fully closed. Considerable force is required to exceed these limitations. However, if the hose is forced beyond these limits, it will be permanently deformed. Certain styles of non-pressure hose are designed to minimize metal to metal contact within the interlocked convolutions, and are therefore very flexible. Conversely, pressure hose is considerably less flexible since the forces necessary to compress the packing material produce a greater resistance to the sliding action.

 

GUIDE TO INTERLOCKED HOSE SPECIFICATION TABLES

Nominal Diameter– This column lists the nominal diameters of the hose expressed in inches.

Strip Metal Thickness– This column indicates the thickness of the strip metal from which the hose is manufactured.

Weight – This column specifies the approximate weight per foot of hose and is given in pounds per foot.

Burst and Working Pressures – This data is applicable only to M-100 pressure hose. Review the M-100 pressure hose specification section for definitions of these terms.

BendRadius– Identified as Minimum Centerline Bend Radius (for M-100 pressure hose) and Minimum Coiling Diameter (for all non-pressure hoses), this column specifies the bending limitations of the particular hose. The following drawing and formulas define these terms.

CONVEYOR HOSE

Smooth Bore Conveyor Hose Cross Section


Description

Penflex manufactures two distinct types of interlocked conveyer hoses designed especially for transfer of dry bulk materials. Standard Conveyor Hose  is a serviceable, unlined, medium weight hose featuring a fully packed interlocked construction.

Smooth Bore Conveyor Hose features rugged interlocking construction plus an integral metal strip lining. This lining provides Smooth Bore conveyor hose with a smooth bore that minimizes impaction and reduces turbulence for free flowing transmission of materials. Smooth Bore conveyor hose can also be produced with the inclusion of packing in the interlocks to reduce air loss and for low pressure requirements.

 

End Fittings

A wide range of end fittings is available for Penflex conveyor hoses. These end fittings can be plain, threaded or grooved nipples, pipe ends, plate flanges, either rigid or floating, and quick disconnect couplings. Attachment can be made by welding, brazing or by high strength adhesives.

 

Specifications

Standard conveyor hose is produced in stainless steel in a range of sizes from 3" to 20" inside diameters. Smooth Bore conveyor hose is produced in a size range from 1 1/2" to 20" inside diameters. Because Smooth Bore conveyor hose is manufactured using two separate pieces of metal strip, the completed hose can be composed of two different types of material. TLSS is an all stainless steel construction for maximum corrosion and abrasion resistance. Smooth Bore conveyor hose is a uni-directional flow hose; make sure that the inlet and outlet end connections are specified. The tables on the following page give complete technical information about Penflex conveyor hoses.

 

Applications

Penflex conveyor hoses are excellent for applications involving the pneumatic transmission of flake or pelletized plastics, grain, coal dust, slag and other dry granular or abrasive materials. It can be used for the loading or unloading of ships, barges, containers, silos, elevators, highway and rail cars. Standard conveyor hose can also be used for air intake for diesel superchargers, exhausting gases from ovens and furnaces, and boiler draft system expansion joints.
