ELECTROINSULATING CONNECTION FOR PIPELINE |
摘要 |
FIELD: machine building.SUBSTANCE: electroinsulating connection for pipeline includes two metal connection pipes. One connection pipe is provided with a flared end, and the other one is provided with section of reduced diameter to be inserted in flared end so that connection zone is formed. End of section of reduced diameter is flared. Between flared end and section of reduced diameter of connection pipe throughout the length of connection there arranged is ring from thermoplastic material with orientation of molecular structure across or at some angle to axis of connection pipes. Length of connection zone is not less than initial diameter of connection pipes. End of connection pipe flared end has external swaging with length equal to flaring length of narrowing section end of the other connection pipe, which provides simultaneous deformation of connection zone with deformation throughout the length.EFFECT: electroinsulating connection for pipelines has high mechanical strength and reliable tightness.2 dwg |
