The cracking furnace tubes are produced by centrifugal casting process.
First , the molten steel is cast into tube patterns of various specifications under the action of centrifugal force, to get the as-cast centrifugal cast tubes;
Second, the inner holes of as-cast pipes are bored on a deep-hole boring machine, the welding bevels are machined by lathe, and the long tubes are assembled and welded.
Third, The long pipes are assembled and welded with extension flanges, reinforced joints, conical parts and other accessories to form reformer pipes ; and when the long pipes are assembled and welded with elbows, tees fittings, lifting lugs and other accessories to form an ethylene cracking pipe.
