"Filament of cotton, asbestos, rubber or metals like copper can be fed into the interlock to make it pressure tight Interlocked metal hose is also referred to as strip wound hose and consists of successive turns of profiled strip, with the edges of adjacent turns interlocked.

Interlock Hoses are made with a packing so that filament of cotton, asbestos, rubber or metals like copper can be fed into the interlock to make it pressure tight.

It is mostly used as a protective/conduit casing. It is also used as a liner inside the hose based on the profile formation.

Types of Locking:

1. Double lock
2. Double lock with packing
3. Square lock with packing
4. Square lock

Applcation

Double Lock Type: This design meets very high standards of tensile and bending strength, Compress and impact resistant against all mechanical stresses. Applications include:

1. B.O.P. hose
2. Liner for corrugated metal hose
3. Dry bulk material handling
4. Fume and dust collections
5. Protective cover on metal hose

Square Lock Type: This design withstands negligible requirements. Applications include:

1. Electronic shielding
2. Wiring conduit
3. Security systems
4. Protective casing
5. Thermocouple
6. Fiber optics

As armour: For telephone & electrical cables, Control instruments & thermo couples, For conveying non penetrating fluids such as tar, naptha, furnace oil
