P355NH Flanges Used For Pressure Purposes?

The specification for standard EN 10028:3 covers a vast expanse of weldable fine grain steels for e.g. – the Flange P355NH. Typically, the EN 10028:3 specified Pressure Vessel Steel p355nh flange is supplied by us in a normalised condition, unless otherwise specified by our client. This carbon steel p355nh flat flange has been designed with the intention of being used for pressure purposes. The minimum yield strength of the specified steel grade EN 10028:3 equivalent p355nh puddle flange meant for pressure purposes, remains about 355 Mpa. This minimum yield strength of the materiale p355nh standard flange, produce by us comes with a set of specific elevated temperature properties.


Flange P355NH

En 10222-4 Grade P355nh Nuclear Gas Industries?

Since this acciaio p355nh threaded flange is one which can withstand being involved in high temperature settings, several industries use them in their day to day applications. For instance, our client list that prefer using the carbon based en 10028-3 p355nh slip on flange includes sectors such as basic ones like Sugar, Paper, Engineering, Textile, Dairy, to a much more complex set up such as Oil & Gas, Chemical & Fertilizers, Petrochemical, Power Generation as well as Nuclear Industries.


Werkstoff P355nh Blind Flanges Weldability Properties?

Because the is en 10222-4 p355nh spectacle blind flange delivered in a normalised condition and the metal is fine grained with excellent weldability properties, our flanges are known to have excellent performance. We use exceptionally high quality raw materials in the production of stal p355nh socket weld flange. Hence, the carbon steel p355nh flange produced in our factory is able to meet the clients most demanding requirements, while delivering a good performance even in elevated temperature environments. Apart from the above mentioned features, other benefits of the acier p355nh blind flange includes its features such as durable, long lasting, easy to use and reasonable in terms of its cost. Thereby making this carbon based en 10273 p355nh forged flanges, we offer at our company, the most cost effective solution.
