近五年来，我国在钢结构领域应用了大直径、厚壁、高钢级双面埋弧直缝焊管，吸收和引进了国外钢管建筑结构和港口海工装备的先进设计理念，重视钢管作为结构件的发展。除了应用于建筑领域，在港口海工装备领域也有成熟的应用，并迅速得到国际业界和同行的认可，取得了丰富的成果。
In the past five years China has applied large-diameter thick wall high steel grade double-sided submerged arc straight seam welded pipes in the field of steel structures absorbed and introduced advanced design concepts of foreign steel pipe building structures and port marine engineering equipment and attached importance to the development of steel pipes as structural members. In addition to the application in the construction field it has also been mature in the field of port marine equipment and has been rapidly recognized by the international industry and peers and has achieved rich results.
目前，平南三桥位于中国广西壮族自治区贵港市平南县，是世界上已经建成的最大跨径拱桥。大桥全长1035米，其主桥桥面宽36.5米，设双向四车道。全桥总用钢量15000吨，设计通车时速为60km/h。2018年9月华洋钢管为平南三桥建设领域直供1200吨DN800钢管，引领着世界钢结构拱桥发展趋势。多年来，河北华洋钢管有限公司蹄疾步稳、快马加鞭，在激烈的国际、国内市场竞争中闯出一片天地，勇立发展潮头。
At present Pingnan Third Bridge located in Pingnan County Guigang City Guangxi Zhuang Autonomous Region China is the largest span arch bridge in the world. The total length of the bridge is 1035 meters and its main bridge deck is 36.5 meters wide with two-way four lane. The total steel consumption of the whole bridge is 15000 tons and the designed opening speed is 60 km/h. In September 2018 Huayang Steel Pipe directly supplied 1200 tons of DN800 steel pipes for the construction of Pingnan Third Bridge leading the development trend of steel arch bridges in the world. Over the years Hebei Huayang Steel Pipe Co. Ltd. has made great strides in the fierce international and domestic market competition.
平南三桥作为世界上同类型桥梁中最大跨径的拱桥，其跨径首次突破550米，拱、梁钢结构首次全部采用大节段制造、运输和安装，拱肋桁架为空间曲线、相贯线整体式节点，精度要求高。
