Φ1016×17·5mm X70螺旋缝管在输气管道工程中的运用

Application of Φ1 016 ×17.5 mm X70 Spiral Seam Pipeline in Shaanxi-Beijing Gas Pipelines

随着西气东输和陕京二线等国内高压、大口径长输输气管道的相继建设,对于国内高压大口径管道的管材选用有了新的认识。在陕京二线输气管道工程中,利用板卷,依靠国内钢管生产厂家来制作大口径螺旋管的方式,大大节省了工程投资。通过国内钢管厂家的预制实验和专家评审,Φ1016×17.5mm螺旋焊管得到了大量的运用,在工程设计中对焊管的运用范围也进行了严格的规定。

After long distant West-East Gas Pipeline and Shaanxi-Beijing Gas Pipeline II with high pressures and large diameters were constructed and put into operation successively,some new acquaintanceship and experience have been obtained in domestic high pressure and large diameter pipeline material selection.Spiral seam pipeline with large diameter used in Shaanxi-Beijing Gas Pipeline II project was made of domestic coils,which saved investment greatly.After prefabrication test and review by domestic manufacturers and experts,Φ1016×17.5×70 spiral seam pipeline was applied in Shaanxi-Beijing Gas Pipeline II project largely and engineering designers specifies its application range strictly.
