Abstract:

A combined computational and experimental technique is developed for implementing a scientifically based approach to the selection of a technology of heat hardening of welded joints of drill pipes made of steel 25KhGM with the use of water-drop quenching. The basic service characteristics of the water-drop cooling device are presented. An analytic model that relates the parameters of the water-drop quenching device (standard size and number of jets in device, pressure of fed water, distance from the jet nozzle to the cooled surface) to the properties of the welded joint is proposed. With the new technique the construction of a quenching device may be developed and the technology of heat treatment of the welded joints of drill pipes optimized in order to increase the level of mechanical properties.
