The final stage in the manufacture of pipes of stainless steel is polished. Polishing of tubular products It represents treatment by abrasive or electrochemical method. For different types of steel tubular products, stainless steel (welded and seamless) It applies a general method of polishing.
Methods for polishing steel pipes: Technology and features
abrasive polishing process technology involves external or internal surface of the pipe using the special abrasives.
Characteristics abrasive polishing method:
- polishing abrasives used initially coarse type, further substances with a fine grain diameter;
- the final polishing step using rolls of felt;
- polishing can be used dry or wet;
- This method is called cylindrical grinding, it is used for polishing of pipe products in most cases.
The essence of an electrochemical polishing method - in the treatment of the surface of tubular structures made of stainless steel with a concentrated acid solution and a circular electrode.
The electrochemical method of watering is different:
- polishing at the outside of tubular products electrodes disposed outside, and the processing pipe inside, they are immersed into the tubular;
- after installation of the electrode is energized;
- This technology allows to achieve a perfectly smooth reflective surface of the product.
Electrolytic-plasma polishing tubes
In recent years, it introduces advanced technology of electrochemical polishing method of tube structures made of stainless steel, which was named for electrolytic-plasma.
Plasma-electrolytic polishing pipe Stainless Steel Products assumes preparation for processing, loading pipe products on the suspension and the consistent implementation of a series of operations in automatic mode:
- electric current supply;
- immersion in an electrolyte solution (pipe therein kept for 2-5 minutes);
- suspension rise;
- disabling voltage;
- washing tubulars;
- drying the warm air stream;
- discharge pipes and quality control processing.
