中文摘要：
油气集输与长输管道及天然气净化工程（下称油气工程）管件的安全运行和使用寿命主要取决于管件标准的内容和标准的正确应用。在油气工程建设中，国内目前常用的管件标准有GB/T 12459-2005《钢制对焊无缝管件》、SY/T 0510-2010《钢制对焊管件规范》、SY/T 0609-2006《优质钢制对焊管件规范》等。在保证管件性能和质量，包括力学性能、冲击韧性、硬度、金相、化学成分和管件的制造工艺规范（MPS）及检验试验等要求上，这些标准均存在不同程度的技术性问题，使管件的安全运行存在潜在的风险。基于此，提出了管件标准在设计与制造方面需要补充的技术要求内容，并对管件标准的修订提出了相关建议。
英文摘要：
Safe
operation and service life of fittings in China's oil and gas field development
projects mainly depend on selection of standards followed in fittings
engineering design. Described are fitting performances, including mechanical
properties, impact toughness, hardness, metallography, chemical composition, manufacturing
process specification (MPS) and inspection
and test requirements, analyzed are various problems existing in adoption of
such common fitting standards as GB/12459-2005,SY/T
0510-2010 and SY/T 0609-2006, which may result in potential risks on safe
operation and service life of fittings. For the purpose of reducing such risks
as far as possible, it is proposed that complementary technical requirements shall be added to
standard adoption in design and manufacture of fittings and current fitting
standards shall be revised.
