摘要:
A method and structural inventive system-construction or mechanism for the figure eight coiling for non-metallic pipelines and conduits, preferred to be of the composite structure and instrumented with detection inventive systems, the coiling which was not previously available and specifically indicated for the means of the long lengths, up to 10 miles, continuous pipelines coiling, transportation and installation at the site. The figure eight inventive system provides for a natural assumption of the bending repose for the pipeline and relaxation of the stresses and preservation of the pipeline's properties from the manufacturing, through the transportation and installation all the way to the site.
摘要:
A transportable system and method for the in situ eccentric manufacturing of reinforced thermoplastic pipelines in continuous lengths up to 10 miles and from 8 to 60 inches in diameter having a rotating frame assembly with a eccentric spools for application of reinforcing tapes and other components to a polyolefin core pipe, and further having a forming machine for cross sectional shape reduction of the reinforced thermoplastic pipelines to facilitate pulling the reinforced thermoplastic pipelines inside a host pipeline. Also provided are continuous monitoring and marking with application of tape in the hoop stress direction and the axial stress direction as well as saturated tape feeding stations for impregnation of the reinforcing tape for in situ curing.
