DOMESTIC PRODUCTION AND APPLICATION OFELECTRIC WELDED BOILER STEEL TUBES

Made of carbon steels and alloy steels,electric welded boiler tubes mainly include tubes for low/medium/high pressure boiler services,tubes for heat-exchanger service and tubes for pressurized piping service.Owing to advantages of this welded tube category such as high geometric accuracy,fine surface quality and cost-effectiveness,application scope of these tubes is getting wider and wider.Electric welded tubes made overseas have been even competetive with seamless steel tubes in terms of quality.Based on the trial production of electric welded boiler tubes by Harbin Steel Tube Plant,the gives us an overview of domestic production and application of this kind of welded tubes.
