Leading Flexible Hose & Expansion Joint Manufacturer & Supplier



SL is made by helically winding two pre-formed strips of metal into a double interlock hose. Through a unique manufacturing process the inner liner becomes an integral part of the hose. It covers the interlock joints to form a relatively smooth inner bore.

Principal Applications
For applications involving large volume transfer of dry bulk materials, the initially higher cost of interlocked hose with an integral strip liner is far outweighed by the advantages it offers over those of other hoses, whether these be of metal, rubber or like materials. The high flow rates for lined interlocked hoses are well known resulting in reduced vehicle turnaround times. Additional advantages are reduced air losses from its tighter construction, elimination of materials degradation and contamination experienced with other hoses, plus a longer service life due to greater abrasion resistance. Ideal for hard to fluidise materials in industrial plants, ships, barges, silos, elevators, trucks and rail units. Uses include pneumatic transfer of bulk materials in powder, pellet, granules, flake or pebble form such as chemicals, feed, flour, grain, plastics, sugar, cement, pebble, lime and sintered iron ore.
