A pipe joint especially suited for coupling two high strength, corrosion resistant pipes. The box end is expanded by a cold working operation thereby eliminating metallurgical problems and changes associated with hot working operations. A sleeve is nested into the internal transition section of the box end to form a sealing surface between the two pipes. Moreover, the sleeve presents a smooth uninterrupted, internal flow surface.

Pipe joint for corrosion resistant alloys

Directed to non-destructive testing, particularly ultrasonic inspection of round stock such as tubing, pipe and rod wherein the inspection is conducted within a water tank to provide ultrasonic coupling of the ultrasonic probe or probes employed wherein the distance between the probe or probes and the surface of the round stock being inspected is maintained essentially constant during the course of the test to assure reliable inspection results and wherein the materials handling aspects of the testing are simplified.

Apparatus and method for ultrasonic inspection of round stock such as

A metal sorter including a pair of electrically conductive probes of identical metallic composition are placed in contact with a metallic specimen. A thermoelectric heat pump is positioned between the two probes to produce a temperature difference therebetween, a temperature sensing device senses the temperature difference and provides an electric signal to control the electric power supplied to the heat pump. A detection device provides an electric signal indicative of the potential difference between the probes.
