Hydroscand Design and Test Center (HDTC)

All our hoses and fluid connectors are subject to rigorous testing in our state of the art test laboratory in Stockholm, Sweden. As a customer you can always feel safe when buying a product from Hydroscand.

In our own internal test laboratory, we have combined 50 years of industry experience with top modern testing facilities. Before a new product reaches the market, it must pass a series of tough product tests to ensure the integrity and performance of our products.

Hose testing – Fleximpulse and impulse

Lifetime testing is performed in one of HDTC's large rigs where up to twelve hoses can be tested simultaneously. This test is used to simulate an accelerated lifetime of a hose assembly. We perform tests in accordance with ISO 6803 (pulse), ISO 8032 (flex-impulse) or according to customer requirements. A typical test includes between 200,000 and 1,000,000 impulse cycles with up to 700 bar and oil temperatures up to 150°C. This test procedure is very tough, but a hose assembly must handle much more than normal operation.


Hose testing – Pressure

For custom hose and pipe assemblies that require certificates, we perform tests before delivery. Hoses are tested with a static water pressure up to 2000 bar. This is a smart way to test – the service life is not affected and even the smallest fault or deficiency can be detected immediately. The same equipment is also used to validate the specified burst pressure of our hoses.


Hose testing – Leakage and burst pressure

Leakage and burst tests are performed to ensure sufficient strength in the hose, ferrule and fitting. The test equipment can also measure the elongation under pressure. We perform tests up to 4,000 bar in accordance with ISO 1402.


Corrosion testing

Corrosion can result in irreversible damage to materials, fluid components, equipment, machinery and pipelines. Such losses are not only expensive to repair, but subsequent equipment failure could result in production downtime, health and safety risks and reputational damage.

HDTC has a climate chamber where we ensure that the corrosion protection meets our quality demands and our customers’ expectations. The test is as tough on hose fittings as the impulse test is on hoses.

In this accelerated lifetime testing, the top coating is generally tested for four weeks in a cyclic test where dry and wet periods are alternated and an acidified 1% salt solution is applied regularly.

HDTC performs tests in accordance with the latest standards for corrosion testing, for example:

  • ISO 9227: NSS Neutral Salt Spray Test
  • ISO 16701: Accelerated corrosion test


Component testing

To achieve a leak-free system requires that all hoses and fluid components are of high quality. HDTC has special equipment for testing other characteristics such as stiffness, surface finish and tightening torque. For flexural strength testing of hoses, HDTC has developed its own machine that provides a way to classify hoses based on bending properties.


We offer a complete range of hoses and fluid components with over 20,000 items. Should you need something very special, we can always help with that as well.
