Pickling and Passivation of Spools

Pickling and passivation are two essential surface treatment processes used in the fabrication and maintenance of stainless steel and other corrosion-resistant alloys, especially in the context of pipelines, spools, and other components used in the oil and gas industry.

The spools used in pipelines or other oil and gas components, pickling and passivation are crucial steps to ensure the long-term integrity and performance of the stainless steel materials. During the fabrication process of spools, welding and other manufacturing processes can introduce impurities and alter the surface properties of the stainless steel. This can lead to corrosion and reduced performance if not addressed properly.
