| Abstract: | It briefly introduced application of X100(690 MPa) high strength line pipes in international pipelines,put forward specific requirements of X100 line pipes based on strain design.It detailedly introduced development and production status of X100 steel plate and steel pipe based on strain design,and carried out inspection for each property and geometry dimension of X100 pipeline steel.The tests and inspection results showed that each property of developed steel pipe can meet design requirements,such as lower yield ratio,enough uniform elongation rate and vaulting shape stress-strain curve.Steel pipe possesses perfect geometry dimension precision,the deviation of ovality is lower,and the range of wall thickness distribution is narrow. |
