t=430℃, p=3.5MPA, steam pipeline, 15CrMoG, SH/T3405, Sch80; cold straining of the pipeline with a coefficient of 0.7 – the amount of cold straining between the two fixing points reached 100 mm. No actual cold straining has been carried out yet. May I ask everyone, is it easy to carry out the construction on site? Is there any experience regarding on-site construction regarding what a suitable cold tightening value is?
