METHOD OF CATHODIC PROTECTION OF WELDED JOINT OF PIPE LINE AGAINST CORROSION

摘要

SUMMARY OF THE INVENTION: trimmed ends sva Riva tubes arranged along the tread edges soluble. Tread placement carried out by welding to the protected surface of the roller-based alloy of aluminum spaced from each of the welded edges defining emom depending on the thickness of the tube wall, the quantities blunting with cutting edges, corner cutting edges and the correction coefficient roller surfacing is carried out portions length is determined depending on the radius of the central pipe and the angle defining the length of the portion before welding alloy based on aluminum platen to the protected surface layer removed by melting maloug- lerodis of the steel or titanium thickness less than 3 mm, a width of 1.0 - 1.5 of the width of the roller 3 f-ly, Table 3. yl 3
