Utilizing our expertise in treating the surface of wire, we have developed plants for in-line pickling and passivating the surface of welded pipes in stainless steel, integrated into the tube manufacturing lines. The Coseco plant may consist of the sole electrolytic pickling and passivating section or be equipped with an additional station for ultrasonic cleaning, depending on customer requirements.
It consists in the following sections:
– Inlet group with adjustable height, allowing for regulating the level of the tube axis in function of the pipe diameter;
– Electrolytic pickling and passivating
– Two stage rinsing
– Ultrasonic cleaning (when required)
– Final drying with hot air
