Parts in the Oil and Gas Industry:
- Pump Barrel
- Plunger
- Valves and Seats
- Sucker Rods
- Polished Rod
- Production Tubes
- Extrusion mandrels for seamless tubing
- Forging dies for valve bodies, couplings, flanges
For manufacturing petrol industry parts like dies and mandrels - see Forging Industry
Requirements for the parts:
- For high Hardness
- For high Wear (abrasion) resistance
- For high Fatigue strength
- For Lower friction
- For Corrosion resistance
Ion Nitriding Solutions:
Significantly increasing the surface hardness, wear resistance and fatigue life of the parts, improving their lifespan and performance.
- Reducing the friction coefficient.
- Increasing the corrosion resistance.
- The core remains soft and ductile, allowing elongation and flexing.
- Allows for tight dimensional tolerance - nitriding causes minimal to no increase in size.
Improving these parameters will save from downtime and maintenance costs.
Steel Grades Used:
Hardness and depth values are recommended for the industry and exact values will depend on the nitriding process parameters.
