The importance of pickling, passivating and cleaning Stainless Steel - Carbon steel cannot be stressed enough. These processes remove rusts, heat scales, weld contamination and can detect faults in the product.


Internal Finish

For hydraulic use the internal wall of the pipe can be coated with a number of oils. I.E. Esso Rust-Ban, Shell Ensis, Tectyl 506 etc. If oil is not required the bore can be Nitrogen purged, or Silica Gel desiccant bags can be inserted into the bore.

External Finish

Where requested external surfaces of pipe can be primed with a paint suitable to customers requirements.

Stainless steel pickling is the most common pickling process used at Metapic’s facility. The most common application for stainless steel pickling is to “ pickle / passivate ”. This is a one-step process which removes heat tint and weld scale while simultaneously passivating the surface of the parts being processed. Most customers are surprised to find out that pickling also accomplishes passivation.
