US Patent:

20190264850, Aug 29, 2019

Filed:

May 9, 2019

Appl. No.:

16/407776

Inventors:

- Arlington TX, US
Eric Luke - Hurst TX, US

International Classification:

F16L 27/103
E21B 17/08
F16L 59/18

Abstract:

A flexible pipe joint has a body and an annular elastomeric flexible element flexibly coupling an extension pipe to the body and operable to pivot the extension pipe with respect to the body. The flexible pipe joint also has an annular flexible boot operable to thermally or chemically insulating the annular elastomeric flexible element from the fluid flowing through a lumen of the flexible pipe joint. The annular flexible boot encircles the lumen, and the annular flexible boot has a first annular end attached to the extension pipe and a second annular end mounted so that pivoting of the extension pipe with respect to the body causes a flexing of the annular flexible boot, and a majority of the annular flexible boot has a shape conforming to shape of neighboring components of the flexible pipe joint.

Abstract:

A telescopic joint for a marine drilling riser has an outer barrel and an inner barrel defining a central lumen for passage of a drill pipe string. The inner barrel is received within the outer barrel, and there is a clearance fit between the barrels for sliding of the inner barrel with respect to the outer barrel while maintaining a coaxial relationship between the barrels. A tubular rolling elastomeric membrane is disposed within the outer barrel and has one end secured to an outer circumference of the inner barrel and another end secured to an inner circumference of the outer barrel for sealing drilling fluid within the central lumen. As the inner barrel slides with respect to the outer barrel, the elastomeric membrane rolls with respect to the inner barrel and the outer barrel so that wear of the seal due to abrasion is eliminated.
