Summary: | FIELD: pipe line transportation. SUBSTANCE: pipe is provided with protector bush concentrically located in it and secured at its end. Outer surface of protector bush which is nearest to end of pipe is insulated and is sealed by layer of dielectric material over section whose length is no less than 2/3 of length of pipe. Area of inner surface of protector bush forming the cavity of pipe is more than or equal to area of inner surface of end of pipe not protected by internal corrosion-resistant coat. EFFECT: facilitated technology of pipe manufacture; enhanced corrosion protection. 1 dwg |
