Pipe connection

A pipe joint formed between a pin section and a box section, the pipe joint comprising:

• the pin and box sections each having a tubular pipe section, engaging at respective first ends in end-to-end arrangement and having a seal element partially therebetween;
• the box section including a box stress collar extending from the first end, the box stress collar being generally cylindrical, axially aligned with the tubular box pipe section and having an inner diameter of the same size as the outer diameter of the pin section, enabling the box stress collar to be placed about the pin section;
• the pin and the box sections being secured together via one or more dogs housed in the box collar;
• wherein the one or more dogs, responsive to exertion of radial pressure thereon, engage corresponding portions of the pin and thereby cause the pin and box to be sealed together;
• and
• the pin section including a circumferential collar located to engage a profiled end surface of the box stress collar on make-up of the joint, the circumferential collar including a circumferential pin channel defined by a pin edge rim, the profiled end surface of the box section including a box channel defined by an inner rim and an outer rim, the circumferential pin channel housing the inner rim of the box and the box channel housing the pin edge rim.
