    First pipe spool fabricated by Petrozavodskmash for NPS in China

    The pipe spools are both straight lengths of the pipeline and connections of same to bent pipes. Inner surface of the pipes is covered with a corrosion-resistant coating, upon which the pipes are connected to the bend pipes. After heat treating, nozzles and sleeves are welded to the pipes, for machining to be done. Necessary inspection and test operations, particularly x-ray examinations, are carried out throughout the entire manufacturing process. A pipe spool manufacturing cycle ends in cleaning, painting, and packaging. Petrozavodskmash is the first manufacturer in Russia which mastered the technology of fabricating seamless clad pipes for nuclear power stations.
