Oil drilling Product Processing Case：4130 75k+625(NiCrMo-3）
This case highlights the cladding process of an API 6A valve body, a key component used in high-pressure oil and gas drilling operations. The base material, 4130 75K high-strength alloy steel, is internally clad with Inconel 625 (NiCrMo-3) to ensure outstanding resistance to corrosion and erosion in high-pressure, high-temperature (HPHT) and sour gas environments.
Oil drilling Product Processing Case：4130 75k+625(NiCrMo-3）
Utilizing automated GTAW/PAW welding techniques, a uniform corrosion-resistant alloy (CRA) layer is applied to all fluid-contact surfaces such as valve bores, sealing surfaces, and connection areas, ensuring strong metallurgical bonding, low dilution, and high integrity performance under extreme conditions.
