FOllowing is melting methods for all Forging Steel valve Body as per client choices
FOllowing is melting methods of Forging Steel valve Body
1. Step 1- Basic EF
Step 2- Either Argon Oxygen Decarburization (AOD) or Vacuum Oxygen Decarburization (VOD) or Vacuum Degrassing.
Step 3- Either Electroslag Remelting (ESR) or Electroflux Remelting (EFR) or Vacuum Arc Remelting (VAR).
Optional Step 4- Vacuum Arc Remelting (VAR)
OR
2. Step 1- Vacuum Induction Melting (VIM)
Step 2- Either Electroslag Remelting (ESR) or Electroflux Remelting (EFR) or Vacuum Arc Remelting (VAR).
Optional Step 3- Vacuum Are Remelting (VAR).
We also provide surface treatment supply capabilities include ENP, chrome plating,tungsten carbide, inconel,monel,stainless steel cladding to meet customers' high-strength,corrosion-resistant, anti-corrosion and other industrial and mining requirements
Following is production process of forging valve bodies
Raw material➝Steel detection➝Steel marking and blanking➝Heating (including tempering)➝Forging processing➝Forging stock inspection➝Heat preservation and normalizing after forging➝Rough machining➝Heat treatment➝CNC finishing➝Product appearance inspection➝Mechanical property test➝Surface treatment and packaging➝Loading and delivery
All our finished forged valve body will have following testing
Mechanical Analysis
Universal Tensile Testing
Brinell and Rockwell Hardness Testing
Impact test
Microscope for microstructure analysis of raw material.
Corrosion Test- (IGC Test)
Non Destructive Tests
Liquid Penetrant Testing (PT)
Magnetic Particle Testing (MT)
UT(ultrasonic testing)
Portable hardness test
Dye Penetration Test (DP)
FOllowing is production and inspection standard of forged valve Body
ASTM A370 (Standard Test Methods and Definitions for Mechanical Testing of Steel Products)
ASTM A751 (Standard Test Methods, Practices, and Terminology for Chemical Analysis of Steel
Products)
ASTM E112 (Standard Test Methods for Determining Average Grain Size)
ASTM A668 (Standard Specification for Steel Forgings, Carbon and Alloy, for General Industrial Use)
API 8A (Specification for Drilling and Production Hoisting Equipment)
API 8C (Specification for Drilling and Production Hoisting Equipment, PSL1 and PSL2)
For our finished production of forged valve Body should have following inspection report
Identification number, material number and designation, order number, drawing number,
Specification Number;
- Heat number, heat chemical analysis, melting method and product chemical analysis;
- Certificate of heat treatment including method of cooling, actual part temperature, holding
time, cooling condition and all re-heat-treatments by complete graphic temperature time;
- Nondestructive testing records,
- Results of all Mechanical Tests,
-Results of residual stress measurements (for process qualification),
- All probable deviation reports,
- Certification of NDT inspector,
- Dimensional and visual inspection report,
- Cleaning Verified
We could make forged, heat treatment and final machined forged valve Body as per clients drawing
