lie at the inside i of the pipeline joint end 34 which is shown located at the upper end of the joint 12 has radially outer with respect to the axis 36 sealing surfaces of the two joint ends 32 34 usually only one which is the upper and outer abutment location 34 has its abutment faces 50 32 forcefully abutting one another when the threads are fully tightened it would require extremely close dimensional tolerances e g less than about 0 02 mm or 0 001 inch to assure forceful abutment of the abutment surfaces at both joint end 32 34 to manufacture the pipe section ends to these tolerances would be difficult and costly applicant causes the inner sealing surfaces 40 42 and the outer sealing surfaces 50 52 to forcefully abut one another and form a fluid seal thereat that prevents the ingress and egress of fluids this also preloads the connector threads to thereby reduce fatigue stresses and stabilize metal to metal seal movement at the pine joint ends 32 34 shown in fig7 the inside i fig1 of the pipe joint is exposed to fluids 60 lying in the pipe which may include corrosive chemicals when the pipeline is used to carry a mixture of hydrocarbons and corrosive components such as is often found in crude oil the outside o of the pipe joint is exposed to seawater or atmospheric conditions in recent years offshore oil production has been conducted in ever deeper waters with the present.
