 METHOD
OF PROTECTING CORROSION-RESISTANT COATING WHEN BUILDING PIPE-LINES
FIELD: pipe-line building.
SUBSTANCE: yoke consisted of three parts is
mounted on the periphery of coating before welding circumferential weld.
Threaded connection is tightened after assembling
the yoke until the corrosion-resistant coating is properly squeezed.
Second yoke is mounted at a distance of 0.25-0.30
of the pipe diameter in much the same way as the first yoke and they are
connected together by means of stud bolts that prevents yokes from axial
displacement.
EFFECT: enhanced reliability of
corrosion-resistant coating. 2 dwg
