Embodiment Construction
[0021] The manufacturing process of the present invention is illustrated below with examples:
[0022] The bimetallic composite pipe with an outer diameter of 159 mm in this embodiment has a base layer of 20# steel pipe with a thickness of 7 mm, and a cladding layer of 1Cr18M9 stainless steel pipe with a thickness of 2 mm and a pipe length of 6 m.
[0023] Multi-layer (inner tube) preparation process
[0024] Cut the 2mm thick 1Cr18M9 stainless steel plate of the cladding material into a 6000mm×451mm blank by a slitting shearing machine, and send it to a tube coiler to roll it into a Φ146mm tube shape (diameter tolerance is ±0.5mm), using an ion automatic welding machine Weld the longitudinal seam, and after the 100% weld seam inspection is carried out by the eddy current flaw detector and the pipe body is reshaped, the semi-finished product is sent to the next production process.
[0025] Preparation process of 20# steel pipe for base
[0026] The base layer uses 20# steel ...
