ABSTRACT OF THE DISCLOSURE The present invention relates to a sleeve for lining a well wall comprising sleeve sections and tubular couplings for interconnecting the sleeve sections. The present invention includes the formation of a sleeve section by friction forging a respective coupling component to each end of a central tubular member. The coupling components are preferably components of the tubular coupling of the present invention. A tubular coupling is disclosed which comprises a male threaded section and a female threaded section. The female threaded section has a shoulder at the base of its thread and the shoulder is engaged by an abut- ment on the male threaded section, when the sections are fully engaged, to thereby provide a seal. The shoulder is under cut and the abutment is complementarily shaped where- by, upon application of a lateral bending moment to the coupling, a radial force is produced between the shoulder and abutment in order to maintain the seal. It is preferred that the threads of the male and female sections are pro- vided on respective frusto-conical surfaces and that a shoulder and abutment arrangement similar to that of com- ponents is provided at the other ends of the threads.
