Patent DE-3928958-A1 (DE)
Inventor: MOYER MARK C
IPC: E21B19/16
Filed: 1989-08-31
Abstract: In an improved method of connecting threaded pipe sections to form a tubular joint (T) having proper sealing positioning at proper make-up torque, the resulting improved connection includes a first pipe section having a registry mark of a prescribed axial width at a predetermined axial position on its exterior surface, to assist in the proper axial engagement of a pin member of the first pipe section with a coupling or box member of the second pipe section. This position is principally determined from finite element analysis. This position is the same for all pin members of a similar size, grade, weight and thread form and therefore can be applied with a template. The pin member and box member are continuously threaded together up to a minimum of an empirically predetermined torque range. This torque range is predetermined by a combination of finite element analysis and experimentation of representative joints for a certain type, size, weight and grade of pipe section. If required, the range is adjusted by empirically determined friction factors to account for different platings, surface treatment and lubricants. While inexpensive, this improvement provides a simple method to visually determine on the rig floor or at the pipe rack whether the joint is properly made up to thereby provide effective sealing of the API (American Petroleum Institute) tapered threaded joint (T). <IMAGE>

Inventor: BIERMANNS FRANZ-JOSEF DR
IPC: C01B21/08
Filed: 1991-07-01
Abstract: The present invention deals with the continuous production of sodium azide from sodium amide and nitrous oxide. This reaction takes place on a support material for sodium amide consisting of a mixture of sodium azide and sodium hydroxide. This mixture is passed through a reactor maintained at temperatures of between 200 DEG  and 270 DEG C.; a portion of the reaction product and the support material are transferred out of the system at an end of the reactor, and a primary quantity of the reaction product and support material are returned to the reactor inlet where the material is combined with fresh, heated sodium amide in an amount corresponding to the quantity of sodium azide transferred-out with the reaction product and support material. With the aid of this continuous process, higher space-time yields of sodium azide can be obtained than in case of the conventional methods without increasing the danger of no longer controllable explosions.
