Precautions For Transportation And Installation Of Wear-resistant Ceramic Lined Composite Pipes

1. Wear resistant ceramic lined composite pipes have high hardness. During transportation and installation, they should be handled gently to avoid serious collisions. It is strictly prohibited for metal instruments to directly contact or impact the ceramic layer on the end face.
2. Wear resistant ceramic elbows have directionality during installation, and the direction indicated on the surface of the pipeline should be consistent with the direction of the medium flow.
3. When installing wear-resistant ceramic lined composite pipes, the centerline of the pipe should be aligned and the height should be leveled to ensure accurate alignment at both ends. The displacement of the two end surfaces should be controlled within 1.0mm.
4. If cutting is required during the installation of wear-resistant ceramic lined composite pipes, a plasma cutting machine or grinding wheel can be used to ensure a smooth end face and avoid affecting the service life due to damage to the ceramic lining. (Gas cutting is not allowed)
5. When using flexible pipe fittings to connect and install pipelines, the insertion length at both ends of the flexible pipe fittings should be adjusted symmetrically. The expansion gap should be determined according to local working conditions or design department requirements. Due to the fact that the thermal expansion coefficient of wear-resistant ceramic tubes is about one-third of that of steel, the expansion gap can be reduced by 3-5mm
6. When using flange connection, the flange end face must be flush with the composite pipe end face. (To ensure the reliability of the connection method.)
7. Due to the excellent welding performance of composite pipes, welding can be used for pipeline connections. During welding, the groove should be a 60 ° -90 ° V-shaped groove with a blunt edge of 2-4mm, leaving no gap. It is recommended to use low current welding.
