Plastic-lined steel pipes are based on ordinary carbon steel pipes,lined with thermoplastic with excellent chemical properties.They are cold-drawn composite or roll-moulded.They have both mechanical properties of steel pipes and corrosion resistance of plastic pipes,slow scaling and are not easy to grow microorganisms.They are ideal pipes for transporting acid,alkali,salt,corrosive gas and other media.(The production process of making plastic lined pipeline)
Plastic lined flanged steel pipes
Plastic-lined steel pipes inherit the advantages of steel pipes and plastic pipes,while discarding their shortcomings. One of the most important contents in pipe design is to determine the pipe wall thickness reasonably according to the use conditions and requirements.At the same time,this parameter directly affects the cost-performance ratio of the product.The unique wall thickness design of plastic-lined steel pipe includes inner plastic pipe wall thickness and outer welded pipe wall thickness,which determines a series of technical characteristics.
- The scope of application is wide and the specifications and varieties are complete.
- Unique production process.
- The connection mode is reliable and fast.
- Surface anti-corrosion measures are perfect and beautiful.
- The wall thickness design of outer welded pipe is reasonable.
- Reasonable wall thickness of inner plastic pipe to ensure diameter.
- Energy-saving and environmental protection, with great potential for development.

Matters needing attention
Maintenance and precautions of plastic lined pipes and pipe fittings before use
- It is forbidden to store in open air for a long time,avoid sunshine,rain,violent collision and multi-layer stacking of heavy objects.
- The sealing surface must not be scraped,cut,scratched,scratched or collided with hard objects.
- Never allow welding,wind cutting and fire-baking on the lined pipe fittings and fittings.It should be more than 1 meter away from the heat source.
