Inert-metal lined, seamless steel-body cylinder

摘要: A seamless steel-body cylinder, suitable for storing ultra-high purity gases, has an inert metal lining. The cylinder lining is preferably nickel and completely covers the interior surface of steel body, preventing stored gas from making any contact reacting with body. conditioned to be smooth, 15 Ra or better. body externally threaded secure end closure devices process comprises steps cutting a pipe form conditioning optionally thermomechanically working ends altered diameters, descaling surface, electroplating layer on interior, heat treating, machining threads into exterior at ends, inside diameters smoothen it sealing which are secured by securing
