The spray process is installed in the production line after welding & scarfing station to offer metallurgical bonding on zinc metal on the tube weld seam. The spray process meets the line speed requirement of 10 mtr/minute to 160 mtrs/minutes to offer high production & uninterrupted spraying process.
