焊接钢管

分析了铸铁管、焊接钢管和聚乙烯（PE）管3种当前城市燃气管网主干管材质的优缺点。

The advantages and shortcomings of the common materials currently used in town fuel gas pipeline network , namely cast iron pipe , welded steel pipe and polyethylene ( PE ) pipe are analyzed .

鉴于我国城市燃气介质将以天然气及液化天然气（LNG）为主，建议焊接钢管为优选，供业主及设计院参考。

Since the town fuel gas used in China is mainly natural gas or LNG , it is suggested that welded steel pipe shall be a preferable choice to be considered by owners and design engineers .

UOE成形工艺在大直缝焊接钢管生产中的应用

Application of UOE forming technology for the large longitudinal seam arc welding steel pipes

在ERW焊管机组生产中，带钢的硬弯大小直接影响焊管机组的正常运行及焊接钢管的质量。

During the production of ERW steel pipe mill , the size of steel of strip hard bent influences the running of pipe welder and the quality of the pipe .

采用失效评估图（FAD）技术，引入可靠性理论，建立了油气输送管线用焊接钢管的可靠性评估模型和方法，即基于FAD技术的MonteCarlo方法；

Reliability calculation model and method for welded steel pipe used in oil and gas pipeline are established with reliability theory based on failure assessment diagram ( FAD ) technology , namely , Monte-Carlo simulation calculation method based FAD .

介绍了UOE成型大直径直缝焊接钢管生产的工作原理、主要工艺及其机械设备构成等。

Manufacture of large - sized straight weld pipes with UOE deforming process is described here , covering the operation principle , major techniques and mechanical equipment composition .

APISPEC5L标准和GB/T9711.1-1997标准中都明确规定，外径尺寸不小于508mm的焊接钢管必须进行静水压试验，所以静水压试验机是重要的检验设备。

Since it is specified in both API Spec 5L and GB / T9711.1 - 1977 that any steel weld pipe with O. D. no smaller than 508 mm shall be subject to hydrostatic test , the hydrostatic testing machine is regarded as a rather key inspection facility .
