    摘要: A production method of a metal pipe which can suppress quenching defects is provided. In the production method of a metal pipe according an embodiment of the present invention bend of the metal pipe is straightened by a straightening machine 10. Next, both pipe end portions of the metal pipe whose bend has been straightened are cut off by a pipe cutting apparatus 20. Next, a plurality of the metal pipes whose both pipe end portions have been cut off are aligned in the axial direction thereof to be conveyed to a quenching apparatus 30, and the metal pipes are quenched by being cooled after being heated by induction heating.

    摘要: A method for producing a wear-resistant and corrosion-resistant stainless steel part for a nuclear reactor is provided. This method includes steps of providing a tubular blank in austenitic stainless steel whose carbon content is equal to or lower than 0.03% by weight; shaping the blank; finishing the blank to form the cladding; hardening the outer surface of the cladding by diffusing one or more atomic species; the blank, before the providing step or during the shaping or finishing step, being subjected to at least one solution annealing with sub-steps of: heating the blank to a sufficient temperature and for a sufficient time to solubilise any precipitates present; quenching the blank at a rate allowing the austenitic structure to be maintained in a metastable state at ambient temperature and free of precipitates.

    摘要: A spray quench system is provided with one or more spray quench rings that eject a controlled volume of quenchant spray onto a workpiece passing through the quench rings. Supply of the quenchant to the quench rings is coordinated with control of the quench rings to selectively change the pressure, quenchant spray exit velocity from the quench rings, flow rate or pattern of the quenchant spray onto the workpiece depending upon mass cooling requirements as the workpiece passes through the quench rings.
