摘要

PURPOSE: A one-sided pipe integrally forming a pipe and a coupler and a connecting assembly are provided to prevent leakage, and to expand and contract actively according to change of temperature by adjusting the length easily with forming the connection part in the end of the pipe. CONSTITUTION: A connecting assembly comprises a pipe(10) including a pipe insertion part(14) having the large diameter, a sill(15) having the same height as the thickness of the pipe in the connection portion of the pipe body, plural insertion grooves(13) arranged radially in the outer periphery, and a connecting part(11) having an inclined surface(12) in the end of the pipe insertion part; a fixing bolt(30) inserting the bent end to the bolt insertion groove; an annular pressure ring(20) including a pipe penetrating hole having the same bore as the outer periphery of the pipe, a packing press sill in the end of the penetrating hole to press packing(50), and plural bolt holes formed in the edge and penetrated by the fixing bo and the packing having the triangular section corresponding to the inclined surface and preventing leak between the pipes.
