Interlocked Metal Hose

We are a Manufacturer of stainless steel Interlocked Hose, also known as Stripwound Hose, by helically winding a preformed strip of 304 grade stainless steel over a forming mandrel and folding together the adjacent edges in compliance with ISO 7369 and ISO 15465 standards.

Depending on the preformed shape of the strip, strip thicknesses and mandrel shape, we are able to make a range of different products with a similar outside appearance. Therefore it is most important that our sales staff are fully informed about the application where the stripwound product is to be used.

Featured products are:

  • Polygonal interlocked stripwound exhaust hose
  • 3S interlocked stripwound premium high temperature exhaust hose, special designed to function directly behind the turbo exhaust of trucks
  • Interlocked stripwound exhaust hose lap band clamp
  • Industrial heavy duty interlocked stripwound hose for pneumatic conveyance and exhaust 
  • Flexible interlocked stripwound metal hose diffusion armour to protect hoses and cables (under test conditions the diffusion armour contained a sharp stream of hydraulic oil passing through a 1 mm predrilled hole when the pressure was raised to 800 Bar and held for 1 minute with perfect fluid diffusion happening).
