The tubular connection consists of a continuous threaded thread, a root, a ridge, a flank and a cargo side, as well as a box in which contours are determined by diagonals, ridges, lace edges and cargo sides. At least one filter or cashier, in the original line of the filter or cashier, is a preliminary staggered line.

摘要

A tubular connection that provides a threaded connection for said tubular connection, comprising: a pin member having a constant and coagonal thread having a root, a crest, a flank of engagement and a loading flank, where the lace flank of the thread of the pin member has a base surface and a second surface, the base surface extends radially, out and away from the root at a base angle in radial relation, the second surface extends radially,out and away from the end of the base surface in a second radially related angle, where the second angle is larger than the base angle; and a box member that has a coaxial and constant pitch thread that has a root, a ridge, a lace flank and a load flank, the lace flank of the box member thread has a surface of base and a second surface, where the base surface extends radially, in and out of the root in a base angle in radial relation, the second surface extends radially,2. in the second and second units, inside and outside the bottom of the surface layer; Aacute; Gulo con Relaci Amp; Oacute; N Radial, where the second and AMP; Aacute; Gulo are larger than the EL AMP; Aacute; Bluo Base; characterized by RA AMP; Iacute; Z, Cresta, lace edge and cargo side; In an L amp, there is at least one filter member or cash member; Iacute; the original respiratory system of a filter member or cash member, which is an L amp; Iacute; initial rolling respiratory system; / P
