FOllowing is melting methods of Forging steel valve seat rings
1 EAF: Electric Arc Furnace
2 EAF+LF+VD: Refined-smelting and vacuum degassing
3 EAF+ESR: Electro Slag Remelting
4 EAF+PESR: protective atmosphere Electro Slag Remelting
5 VIM+PESR: Vacuum induction melting
We could forged, heat treatment and final machined valve seat rings as per clients drawing
Also we could do following surface finish of all our forged valve seat rings
-ENP
-Chrome Plating
- TIN Coating / Titanium Nitride Coating
-TCC(Tungsten Carbide Coated)
-Chrome Carbide
-Stellite Coated
-Inconel Coated
-Special Coated
We are able to provide any kind of NDE ( Non-Destructive Examination) tests for our all finished forged steel valve seat rings .
PT (Penetrant test)
UT (Ultrasonic test)
PMI (Positive material Identification)
MT (Magnetic test)
Thickness test (for cladding, plating or coating)
Alcohol Test (for MTM kits)
Corrosion Test
All our finished forged valve seat rings can be Third-Party Inspections (TPI) such as TUV, Lloyds Register, DNV, ABS, BVIS, etc., for EN 10204-3.2 certification.
ALl our finished forging steel valve bonnet should be accepted by the QC department of the manufacturer by conducting the following
examinations:
1) external examination;
2) a check of dimensions and marking;
3) chemical composition examination;
4) mechanical tests;
5) macrostructure examination;
6) residual stress measurement;
7) ultrasonic testing;
8) periscopic testing.
