Flexible Metal Hose assemblies installed in a Natural Gas, Town Gas, Tempered Liquefied Petroleum Gas (TLP) or Liquefied Petroleum Gas (LPG) application need to be manufactured and certified to a strict set of rules in compliance with the Australian Gas Association (AGA) approval to AS4631-2005. Certificate No 6745.

Standard and Super-flex hose assemblies from 6mm to 50mm I.D. MWP of 2600kPa. Standard and Super-flex hose assemblies from 65mm to 200mm I.D. MWP of 1500kPa.

Convoluted Technologies manufactures Interlocked hose by helically winding a preformed strip of 304 grade stainless steel over a nominal bore forming mandrel and folding together the adjacent edges.

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 product is to be used.

Any weld-able fitting can be incorporated into a convoluted hose assembly, and in any configuration, while other hose types require special shanks and collars. This can be a benefit over other hose types that would require multiple threaded connections to connect several hoses together. Every threaded connection is a potential leakage point, so every welded fitting eliminates a leakage point and can facilitate installation.

Hose internal and external protection with interlocked amour.

To prevent abrasion and over bending, an amour metal interlocked hose can be used as a protective cover over wires or even other hoses. Interlocked hose can be very abrasion resistant, making it ideal for use as protection to corrugated hose from either abrasive media or external damage. Interlocked hose can also be applied to the outside of a corrugated hose to prevent it from over bending. Bending a corrugated hose is one way to excessively fatigue the metal hose of an assembly. However, interlocked hose cannot be over bent without pulling the hose apart, making it an excellent bend restrictor when installed on a corrugated assembly.

New product release, Convoluted Technologies Pty Ltd is proud to announce we are able to supply the oxygen Lancing industry with a complete selection of lance pipes.

Oxylances The Oxylancing process is commonly used in metal smelters to open tap holes, tundish nozzles, ladle sliding gates - for oxygen injection, ladle maintenance activities, skull cutting and scrap metal cutting. Oxylances can also be used in the maintenance industry; it is an easy way to remove frozen pins on earth moving equipment or in industrial applications and for the demolition industry to cut fast through large volumes of concrete, where noise or vibration are unacceptable, or where speed is essential particularly on reinforced concrete. The equipment is extremely simple and easy to operate, and the capital cost in comparison to drills etc. is negligible
