Abstract
Borerørforbindelse med en forMndelsesnippel (2) som har en over en bestemt lengde utstrakt, gjengefri og fortykket midtre del (13)- Ved avslutningen av midtdelen er det en respektiv ytterskulder (11,12) og utfor disse er det et respektivt kjegleformet ytter-gjengepari (3,4). Disse gjengepartier samvirker med komplementære innerg;) enger (5,6) i de som muffeelement-er utformede rørender. Ved sammenskruingen vil den respektive rørende legge seg tett an mot den nevnte ytterskulder (11,12) på midtdelen (13). En slik borerørforbindelse egner seg særlig for ekstremt dype boringer. Man holder seg innenfor de normerte dimen-sjoner, med optimal vekt, samtidig som det oppnås bedrede dynamiske forhold sammenlignet med tilsvarende standardforbindelser hvor det benyttes påsvelsede skjøtender. Borerørforbindelsen er kostnadsgunstig og har lang levetid.
