연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A pipe joint between cylindrical male and female couplers having terminal end portions with cooperating cam surfaces that facilitate assembly of the couplers. Cooperating projections on the couplers cam past one another when the couplers are assembled and restrain the couplers against separation. A gasket is interposed between the couplers, and the couplers are articulatable at least several degrees to permit some curvature to a string of pipe. The couplers have splines received in annular sockets in the ends of pipes, and the sockets are filled with adhesive to retain the splines therein. The gasket is prelubricated and protected by a plastic wrap that also provides protection against ultraviolet rays. Cylindrical ring couplers are formed by extruding a strip having a coupler cross-sectional profile, cutting a length of the strip and fusing the ends at a joint. The joint is deburred and polished, and the ring is heated and placed on a mandrel where the ring cools to relieve stress in the plastic and provide the final cylindrical configuration.

The coupler of claim 1 wherein said female coupling portion is displaced radially outwardly of said longitudinal axis from said spline portion, said spline portion having barbed inner and outer surfaces, and said spline portion providing no part of any fluid flow passage through said coupler. 3. The coupler of claim 2 wherein said female coupling portion has a cylindrical inner surface 38 and further including a transition portion 54 between said spline portion 32 and said female coupling portion 34, said transition portion 54 extending toward said longitudinal axis 30 from said cylindrical inner surface 38 and having a concave curved inner surface 52, 52a facing in a direction toward said shoulder 48. 4. A cylindrical male pipe coupler having a longitudinal axis, said coupler having a spline portion and a male coupling portion extending generally parallel to said longitudinal axis, said male coupling portion having inner and outer surfaces and a terminal end, said outer surface including a circumferential groove spaced axially from said terminal end and having opposite inner and outer groove sidewalls, a sloping cam surface extending from said terminal end in a direction away from said longitudinal axis and back toward said spline portion to a first intersection with said outer groove sidewall, said outer surface including an outwardly extending circumferential projection adjacent said inner groove sidewall, said projection having a projection outer surface that slopes from said inner groove sidewall in a direction away from said longitudinal axis and back toward said spline portion to a second intersection with a projection inner sidewall, and said second intersection being spaced outwardly from said longitudinal axis farther than said first intersection. 5. The coupler of claim 4 wherein said male coupling portion is displaced inwardly toward said longitudinal axis from said spline portion. 6. The coupler of claim 4 including a transition portion between said spline portion and said male coupling portion, said transition portion having a concave curved surface adjacent said outer surface of said male coupling portion that faces toward said terminal end. 7. The coupler of claim 4 including an elastomeric gasket having a gasket base portion received in said groove and having a sealing portion that is inclined in a direction toward said longitudinal axis and back toward said spline portion. 8. The coupler of claim 7 wherein said groove has a groove bottom and said gasket base portion is adhesively bonded to said groove bottom. 9. The coupler of claim 7 including a lubricant on said gasket, and a removable protective wrap covering said gasket and lubricant. 10. The coupler of claim 9 wherein said wrap provides protection against ultraviolet radiation. 11. A pipe joint between a cylindrical male coupler received in a female coupler, said male and female couplers having terminal end portions with cooperating cam surfaces that facilitate insertion of said male coupler into said female coupler, said male and female couplers having cooperating projections that cam past one another when said male coupler is inserted into said female coupler and that engage one another to inhibit longitudinal separation of said male and female couplers, a gasket on said male coupler between said male coupling terminal end portion and said male coupler projection, and said female coupler having an inner surface sealingly engaged by said gasket. 12. The joint of claim 11 wherein said male and female couplers have longitudinal axes and said male and female couplers are configured to be articulatable to skew said axes up to at least several degrees when said projections have been cammed past one another and said male coupler is received in said female coupler. 13.
