Parker Hose Assembly Manufacturer certificate for DORING LLC for thermoplastic hose assemblies up to 4000 bar

Moscow, Russia, 27. August 2020 – DORING LLC, official distributor of Parker Hannifin, the global leader in motion and control technologies, in Russia, Moscow, has received the “Parker Hose Assembly Manufacturer for thermoplastic hose assemblies up to 4000 bar” certificate. It signifies production boost and certification of high-pressure hoses with a maximum operating pressure of 4000 bar. DORING is the first and only Parker distributor in Russia that offers hose crimping at such a high-pressure range.


Until recently, both distributors and customers have been obliged to source high-pressure hose assemblies produced in Germany by the Parker Polyflex division. The process was time-consuming and rather limiting in terms of the possibility of adjusting the parameters of the ordered products to individual needs. Now, thanks to the rapid manufacturing, crimping, testing, and certification of high-pressure hoses of any length and specification (with all activities taking place in Russia), DORING offers assembly of hydraulic hoses for immediate delivery with the use of Parker components. These are assembled according to the needs of the customer, ensuring top quality and durability of the product. The delivery time of UHP hoses is also significantly reduced and competitiveness increased.


The certificate obtained by DORING is the only authorization to manufacture this type of hoses. Thus, the hose operating pressure can reach up to 4000 bar; each test performed at the test stand enables the issue of an authorization for any hose ordered by the customer. Ultra-high-pressure hoses manufactured this way can be used; for example, in hydraulic tools, waterjet cutters for steel, plastics, ceramics or concrete, cleaning in corrosion protection processes, cleaning of airport runways, as well as in the power generation and heating industry or during tests of diesel engines in injector testing systems.


A number of requirements relating to the process of high-pressure hose manufacture had to be met, in order to obtain the certification. DORING was required to have a certified test stand for testing high-pressure hoses and accessories for the pre-assembly, marking, cleaning, and securing of hoses, as well as a specialist machine for hose crimping and product storage.


DORING has been cooperating with Parker Hannifin for 11 years, offering connectors, industrial and mobile hydraulic products, and pneumatic products, mainly for the mining and metallurgy industry, and the oil & gas industry. Currently, the company has 10 regional offices throughout Russia with central and regional warehouses and 5 ParkerStores. The UHP thermoplastic hose production centre is another service initiative of the Russian distributor, following the currently operating Hose Assembly Centre and the Hose Doctor - 24-hour mobile technical emergency service with a main focus of quick, on-site repairs, eliminating high downtime costs.
