ASME SA516/ASTM A516 GR.70N BAFFLE PLATES,SA516 Grade 60/70 BAFFLE PLATE,TUBE SUPPORT PLATE

We are professional ASME SA516/ASTM A516 GR.70N BAFFLE PLATES,SA516 Grade 60/70 BAFFLE PLATE,TUBE SUPPORT PLATE manufacturer and exporter in china.
A516 Grade 70  are mainly used in welded pressure vessels where improved notch toughness is important.Generally As rolled is ok for rolling pressure vessel steel plate A516Gr70,however,for improve steel property and toughness,we suggest the end users accept rolling A516 Grade 70 steel plates under Normalized,especially for the steel plates thickness above 40mm.NACE MR-0175 A516 Grade 70 also offered by us with HIC test and SSCC test
ASME SA516-ASTM A516 GR.70N BAFFLE PLATES,SA516 Grade 60-70 BAFFLE PLATE,TUBE SUPPORT PLATE

Baffle plate is widely used in shell and tube heat exchanger, boiler, pressure vessel, steam turbine, large central air Conditioning, etc. The baffle sheet is mainly used for chemical containers, such as shell and tube heat exchanger, Boiler, pressure vessel, condenser, central air conditioning, evaporator, water desalination with the function of Supporting the tube bundle and improving heating efficiency.
The material of metal makes it not only has the very strong rigidity, and has a great deal of heat conduction performance.

Application of baffle plate: Heat exchanger, boiler, pressure vessel, steam burbine, air conditioning., etc
Function of baffle: Support and fix the tube and shell, heat conductive, corrosive resistant, high pressure
