Claim:
A pipe joint comprising: a first pipe member having a circular cross-section with inner and outer diameters at an end, said end of said first pipe member having a plurality of male threads with a steep taper angle in the range of 20°–60° and a spiral buttress profile; a second pipe member having a circular cross-section with the same respective inner and outer diameters at an end, said end of said second pipe member having a plurality of female threads with the same steep taper angle and the same spiral buttress profile in engagement with said male threads, wherein matching surfaces of said male and female threads have a squeeze angle as the threads are brought into engagement of between 0.5 degrees and 5.0 degrees, said male and female threads have a pitch such as to result in 3 to 6 full threads across a thickness of a wall of each pipe member, said male and female threads have a surface relief pattern formed thereon, and said male and female threads have multiple start locations for thread engagement whereby said male and female threads may become fully engaged in less than one relative rotation; and a cured adhesive material spread across adjacent load-bearing surfaces of said male and female threads which bonds said male and female threads.
