Hydraulic Fittings and Ferrules

admin — Mon, 10 Jan 2022 11:14:44 +0000

Fittings for high pressure hoses are assembled on hydraulic hoses with the use of special ferrules. Designed especially for rubber hydraulic hoses and thermoplastic hoses but widely used for industrial hoses as well. Assembled by screwing (reusable) or on crimping machines (permanent connection). Our offer includes a wide range of fitting types – depending on a connection part (metric, imperial, etc.).

Hydraulic Fittings and Ferrules

Thermoplastic hoses are designed for pressure not exceeding 800 bar. External layer manufactured from abrasion resistant polyurethane, internal layer of polyether or polyamide reinforced by max 3 layers of steel or aramid braid. Widely used in hydraulic systems, rescue equipment, lifts and pumps for hydraulic oil, paints, solvents, isocyanines and polyols.

Thermoplastic Hoses

admin — Mon, 10 Jan 2022 07:35:50 +0000

Hoses for medium and high pressure made of thermoplastic polymers (such as polyester, polyamide, polyurethane) reinforced by max 2 layers of steel or textile braids. Most types manufactured to certain standards i.e.: SAE J517 (for hoses SAE 100R7 and SAE 100R8), DIN 24951, ISO 3949 and PN-EN 855. Those standards in details describe two types of hoses: with double textile braid (R7) and double aramid braid (R8). Thermoplastic hoses widely used in hydraulics, airless paint spray, air and compressed gases, chemicals and water cleaning.

Thermoplastic hose characteristics:

very low weight (even up to 60% lighter compared to rubber hose),
compact structure (small external diameter in proportion to the internal one),
small bend radius,
good chemical resistance of an internal layer to hydraulic oil and chemicals,
very smooth internal layer surface that reduces the loss of flow rate,
resistance to ageing, ozone and ultraviolet radiation.
resistance to abrasion of external layer (polyurethane).

Pinpricking of external layer:

Pinpricking is defined as pricks (micro holes) in an external layer of a hose. It prevents gas build-up under the external layer which is a result of permeation of gas particles through the material over longer operation time. It is recommended to pinprick the layer particularly for high pressure gas transfer and nearby fittings. Pinpricking is factory-made or after crimping of complete hose assemblies.

Static electricity:

If it is vital for particular application to conduct electrical charge away from the hose (hose for paint, organic solvents, hose with high flow rate of a medium), the choice of the hose with a metal braid or additional conductor (conductive fibre in a braid, etc.) is recommended. It is vital to mount fittings in such a way so as to obtain electrical conductivity of the hose assembly in such a way we can achieve electrical conductivity of the hose assembly.

Twin and multiple hoses:

The twin version of thermoplastic hoses (two hoses with external layers joined together) among other applications is used for fork-lift trucks, hydraulic installations of machine tools and process lines. A multiple hose version (three or four pieces, etc.) is available on special request.

Assembly:

It is recommended to use for thermoplastic hoses Z type fittings (assembled with the use of crimping machines). In some cases S type reusable fittings can be used.

WATERBLAST Hoses

admin — Mon, 10 Jan 2022 07:21:48 +0000

Rubber hoses with 4 or 6 steel wire braid reinforcement designed for UHP (850-1400 bar). Designed for waterjet cutting and waterjet cleaning equipment and not recommended for hydraulic oil applications. Widely used for cleaning of chemical and power supply installations, cleaning and cutting of concrete construction, pavement, steel surface and steelwork, tanks, vessels, mining installations. WATERBLAST hoses are available only as hose assemblies (crimped with special type of fittings). Each hose assembly is pressure tested.
WATERBLAST sample hose: base hose – WATERBLAST 40, DN 1/2”, working pressure 1000 bar, M24x1,5 (DKOS) female fittings on both ends, Lc= 20000 mm.

HYDRAULIC HOSES

admin — Mon, 10 Jan 2022 07:19:31 +0000

Rubber hydraulic hoses are used for power transmission and control in hydraulic systems. Designed for hydraulic oil, working temperatures from -40 to +100°C and working pressure till 420 bar (42 Mpa).

Due to its construction, hydraulic hoses can be divided into following categories:

hoses with textile braid (one or two layers).
hose with one or two layers of steel wire braid (one, two and three layers).
hoses with spiral wire braid (four or six layers).

Hydraulic hoses are manufactured in imperial sizes and standardised. The most popular standards defining requirements for hoses are as follows: American SAE, German DIN, International ISO and European EN.
Apart from standardised hoses (according to above mentioned norms) our offer includes hoses with increased flexibility, higher working temperature, increased abrasion resistance of external layer or better chemical resistance.

For a proper choice of hydraulic hose to a particular application below mentioned aspects has to be taken into account:

working pressure and working conditions (static/dynamic),
medium and ambient temperature.

Hydraulic hoses designed for mining applications must fulfil additional requirements connected with explosives and fire conditions present in mines.
Hydraulic hoses assembled with the use of fittings crimped on crimping machines.
