The composite pipe and pipe fitting are carbon steel or cast iron pipe with coated special ceramic lining concreted to the base material. The composite paint for the special ceramic lining consists of diabase powder, quartz powder, graphite, ceramic powder, granite sand, fluorosilicate, and alkali sodium silicate solution or potassium silicate solution. The production process of the composite pipe and pipe fitting includes pre-treatment of the pipe or pipe fitting, mixing and grouting slurry, centrifugally solidification and acid pickling. The present invention has anticorrosion grade over grade 10, can resist +/-0.1 MPa pressure and 0-300 deg.c temperature for long period without falling, has good incompatibility and is also suitable for curved pipe and reduced pipes. |
