ASTM A516 GR.70 Dishead , Boiler and Pressure Vessel application
From 2011 to now , YUHONG GROUP already support Dishead to more than 300 client, the dishead was width used in Boiler, Heat Exchange, Pressure Vessel , Chemical Tank ,... YUHONG woundful experience can support client well .Yuhong Group supply high quality dishead for boiler and pressure vessel fabrication which is ideally suited to the high standards set by the oil, gas and petrochemical industry – this is why we stock an extensive range of carbon plates according to ASTM A516 Grade 70.
ASTM A516 Grade 70 is an excellent choice for service in lower than ambient temperature applications, has excellent notch toughness and is used in both pressure vessels and industrial boilers.
A516 Grade 70 offers greater tensile and yield strength when compared to ASTM A516 Grade 65 and can operate in even lower temperature service.
Our plates come with mill certification in accordance with EN10204 3.1 or EN10204 3.2. Our plates are fully traceable, usually with hard stamping and we welcome any third party or customer inspection if required which can be arranged with the client.
