Production of ultra high pressure (UHP) hose assemblies up to 4000 bar

We offer UHP assembly services from our in-house workshop, where we produce complete flexible hose assemblies (hoses with fittings) with a working pressure up to 4000 bar. The production is performed by certified personnel, from tightly controlled materials. All hose assemblies are pressure tested before they are delivered to the customer.

Application:

  • pipeline and heat exchanger cleaning

  • surface cleaning and preparation, paint removal

  • concrete hydrodemolition

  • waterjet cutting of steel and other materials

  • hydroforming

  • hydraulic bolt tensioning

  • hydrostatic pressure testing stations

  • hydraulic rescue tools

Bend restrictor

Polyurethane bend restrictors significantly increase operational safety and extend hose service life. They are lightweight and easy to install. Designed for ultra high pressure hoses. For hoses with lower working pressure and for other applications, use standard rubber restrictors. Selection in consultation with Tubes International.

Hose securing grip

Steel securing grip is a piece of net used to protect the operator in case of e.g. whipping of a fitting. Very easy installation, also on running systems – the hose assembly is disconnected from the system on one side for the mounting time. If the hose assembly breaks at the fitting-coupling connection or the fitting suddenly detaches, the net tightens and shrinks on the hose restraining its moves and causing to stop.

Protection hose

To protect the outer surface of the hose, an additional hose can be pulled on as a cover. Helix-reinforced plastic hose cover protects Spir Star® hoses for Waterblast applications where high friction against ground occurs. Plastic hose cover, without reinforcement, protects hoses for high-pressure hydraulics where friction is lower and it is important to maintain maximum flexibility. To have a protective hose matched with Spir Star® hose, the diameter of the Spir Star® hose ferrule after crimping must be smaller than the internal diameter of the protection hose.

Hose assembly testing

Every ultra high pressure hose we produce is tested up to 4800 bar. We issue a certificate for each ultra high pressure hose assembly, confirming that the pressure test has been carried out.
Tubes International’s machine shop is fitted with equipment, which allows for testing complete hose assemblies, repaired or modified assemblies with working pressure up to 4000 bar and 6000 bar. The use of an innovative electric drive combined with an automation system in the machine capable of performing pressure tests up to 6000 bar allows for each test stage to be specified in accordance with ISO 1402 requirements.
