Interlock Hoses

The Interlock Hoses are the helically coiled high quality metallic strip that is mechanically locked with the adjacent edges folded together to form interlocked convolutions (two profiled lock sections). These hoses are made using copper coated steel, aluminum and stainless steel in different sizes and specifications. The hoses are sturdy in construction and can bear temperatures up to 800°C. They are used in medium pressure applications (15- 20 PSI) and can also be used as an outer jacket for insulated pipelines and for various articulated movements. Plus, to minimize leakage and to make the hose pressure-tight, interlock flexible metal hose can be manufactured with various packing materials (fabrics and elastomer), which may be inserted along the entire length of the hose offering a protective/conduit casing.

Construction

Size:4mm – 300mm
Hose Material:SS 304 / SS 316 / Galvanised Steel (G.I.)
Braid Material:Conduit can be provided with wire Braiding, PVC or synthetic Rubber sleeving
Pressure:15 – 20 PSI
Temperature:-269°C to +800°C
Stainless steel:7500 C, Galvanized steel : 3500 C
Service temperature may vary due to choice of packing material: cotton, rubber, ceramic or glass fiber yarn

Application

These Interlock Exhaust and Conveying Hoses are excellent for applications involving:
Ventilating Lines 
Conveying:The pneumatic transmission of flake or palatalized plastics, grain, coal dust, slag and other dry granular or abrasive materials
Transfering:The loading or unloading of ships, barges, containers, silos, elevators, highway and rail cars for air intake for diesel engines
Exhaust lines:Exhausting gases from ovens and furnaces, and boiler draft system & inside liners for stainless steel corrugated hoses & hose assemblies
Protective Casing:It is also used as a conduit for safeguarding wires, cables & tubing like rubber & corrugated hoses

These are helically wound, strip wound hoses with or without packing of asbestos yarn, copper wire etc. Depending interlock upon the application. These are manufactured S-304 and G.I. in all sizes from 4mm ID to 300mm ID. These are supplied complete with end fittings/flanges as per the customers requirement.

 

These are also supplied with external PVC extruded cover. These are used for engine exhaust applications, liquid handing applications, solid handing applications including suction/blower hose and also for covering corrugated type SS hoses and cables/wires for protection against external abuse.
