Seamless HPL pipes, galvanized or phosphated EN 10305-4 for hydraulic and pneumatic motors

Precision steel pipes used in pneumatic and hydraulic systems, often abbreviated as HPL, are subject to special requirements for anti-corrosion protection. Such protection is fully provided by the seamless steel pipe produced in accordance with the European standard EN 10305-4.

Key Features

In EN 10305-4 pipe corrosion of the base metal is prevented by a protective galvanized layer. In addition, this coating gives the product a more aesthetic appearance.

The protective coating is multi-layered. The zinc layer is applied first, protecting the metal of the pipe itself. The second, which is called passivating, is zinc. In this case, passivation is performed only on the outer surface of the product.

with a silicon base stabilizing the chromium layer.

Products are available in a wide range of diameters and wall thicknesses.

Applications

It is recommended to buy a seamless galvanized pipe for use in the manufacture and regeneration of hydraulic and pneumatic motors, hydraulic pipelines and pneumatic systems.
