Large-dimension interim pipeline with cast iron systems

Large-dimension interim pipeline with cast iron systems

Positive locking and flexible thrust-resistant systems have extended the range of application of ductile cast iron systems and shown that they can withstand all loads produced by internal and external forces. In the construction and during the operation of pipelines with restrained joints in tunnels and under bridges, when used with the application of trenchless installation techniques …
