Phosphating Production Line for Oilfield Pipe Couplings
Contact UsThe Phosphating Production Line for Oilfield Pipe Couplings is a highly specialized, fully automated surface treatment line designed specifically for pipe couplings (threaded connectors) in the oil and gas drilling industry. It focuses on achieving a high-quality, uniform manganese or zinc-manganese phosphate coating on both the internal and external surfaces of couplings. The core objective is to impart excellent rust prevention and anti-galling properties, ensuring reliable sealing and connection in extreme downhole environments. The line integrates automatic loading/unloading, precise positioning, combined high-pressure spray/immersion processing, enclosed temperature control, and wastewater recovery systems. Process parameters are strictly optimized to meet the rigorous surface treatment standards (e.g., API) for threaded components.
