Zusammenfassung:	This disclosure relates to weldments useful as heat transfer tubes in refinery processes dealing with gas phase hydrocarbon process streams at high temperatures. This disclosure also relates to tubes that are useful in refinery processes dealing with gas phase hydrocarbon process streams at high temperatures. The weldments include a tubular member and at least one mixing element. The tubular member comprises an aluminum-containing alloy. The mixing element comprises an aluminum-containing alloy. The mixing element's aluminum-containing alloy can be the same as or different from the tubular member's aluminum-containing alloy. Other aspects of the disclosure relate to refinery processes dealing with gas phase hydrocarbon process streams at high temperatures which include such weldments.
