石油天然气金属管道焊接工艺评定：石油天然气输送焊管在我国的应用和发展

石油天然气金属管道焊接工艺评定：石油天然气输送焊管在我国的应用和发展直缝埋弧焊管在中国应用于油气输送工程比较晚，但起步迅速，发展步子大，成绩显著。因为它有下列优点：Hebei Huayang Steel Pipe Co. Ltd. specializes in the production of straight seam steel pipes which are not only used in the construction field but also maturely used in the field of port offshore equipment and has achieved fruitful results.除此之外，茂名港博贺新港区东区油品码头工程是广东省重点项目，油品码头工程新建1个10万吨级油品泊位、4384米公用管廊及配套设施。水域公用管廊钢管桩总量607根，其中斜桩322根，直桩285根。为使项目顺利推进，河北

油气输送焊管在我国由于“西气东输”工程的拉动，促进我国冶金工业热轧板卷发展很快，由于有了原料支撑，钢管企业蓬勃发展，关键设备从国外引进，很快达到或接近世界先进水平。

Oil and gas transmission welded pipe in China due to the "West-East gas transmission" project pull promote the development of China's metallurgical industry hot-rolled plate and coil quickly due to the support of raw materials steel pipe enterprises flourished the key equipment imported from abroad and soon reached or close to the world's advanced level.

石油天然气输送对管道的通用技术要求主要有三点，一是必要的强度、刚度、冲击韧性和可焊性，由于输送介质—石油和天然气的不相同以及天然气有富气和常用的已净化过的天然气的区别，以及有输送的地段不同，对钢管有不同的技术要求。

Oil and gas transmission on the general technical requirements of the pipeline are mainly three points one is the necessary strength stiffness impact toughness and weldability due to the transmission medium - oil and natural gas is not the same as well as natural gas has a rich gas and commonly used has been purified by the difference in natural gas as well as there are different transmission of the lot there are different technical requirements for steel pipe.

除此之外，茂名港博贺新港区东区油品码头工程是广东省重点项目，油品码头工程新建1个10万吨级油品泊位、4384米公用管廊及配套设施。水域公用管廊钢管桩总量607根，其中斜桩322根，直桩285根。为使项目顺利推进，河北华洋钢管有限公司各级领导高度重视，全力推动项目进度。充分利用华洋钢管的优势，为茂名港博贺新港区东区油品码头的工程提供高质量、高水平的钢管。

In addition the oil terminal project in the eastern part of Bohe New Port Area of Maoming Port is a key project of Guangdong Province with a new 100 000-ton oil berth 4 384 metres of utility corridor and supporting facilities. The total number of steel pipe piles in the water utility corridor is 607 including 322 inclined piles and 285 straight piles. In order to make the project progress smoothly leaders at all levels of Hebei Huayang Steel Pipe Co. Ltd. attached great importance to the project and made every effort to promote the progress of the project. We make full use of the advantages of Huayang Steel Pipe to provide high quality and high level steel pipes for the project of oil terminal in the east area of Bohe New Port of Maoming Port.

河北华洋钢管有限公司专业生产直缝钢管，除了应用于建筑领域外，又成熟的运用于港口海工装备领域，并取得了丰厚的成果。

Hebei Huayang Steel Pipe Co. Ltd. specializes in the production of straight seam steel pipes which are not only used in the construction field but also maturely used in the field of port offshore equipment and has achieved fruitful results.

直缝埋弧焊管在中国应用于油气输送工程比较晚，但起步迅速，发展步子大，成绩显著。因为它有下列优点：

Longitudinal submerged arc welded pipe was applied to oil and gas transmission projects in China relatively late but it started rapidly developed at a large pace and achieved remarkable results. Because it has the following advantages.

①成型工艺比较容易，有预焊及精悍，焊接质量比较容易保证；

① the forming process is relatively easy there is pre-welding and fine hummer welding quality is relatively easy to ensure.

②有全管扩径工艺，比较容易消除应力，残余应力较小；

② there is a full tube expansion process easier to eliminate stress residual stress is smaller.

③几何精度和力学性能较好，质量稳定，可靠性高；

③Geometric accuracy and mechanical properties are better stable quality and high reliability.

④应用广泛，可以应用于油气管线，可以用于陆上二、三、四类地区、穿越段及海底管线；

④ wide range of applications can be applied to oil and gas pipelines can be used in onshore Class II III and IV areas crossing sections and subsea pipelines.
