No matter which method is used for the steel-cased steel steam direct-buried thermal insulation steel pipe, there will be no defects such as annulus, cracks, and delamination. Directly buried steam pipelines are constantly updated. Sealed and waterproof.
Encyclopedia of methods for direct burial of steel jacketed steel steam insulation steel pipes
1. Steel jacketed steel steam directly buried thermal insulation steel pipe 3. After careful inspection in the factory, the manufacturers of steam thermal insulation pipes were studied. Rock wool and rock wool fibers shall not appear bubbling or peeling off the veneer layer, and the protective layer shall be hollowed out or peeled off, and shall not cause water seepage cracks. Under pressure, the steam insulation pipe shall be discharged from the air. Then it was done in two steps: stabilized, no leaks for 10 minutes.
2. Steel jacketed steel steam directly buried thermal insulation steel pipe working steel pipe (core pipe): a pipeline for conveying steam. The thermal insulation pressure test at the connection of the thermal insulation pipeline is qualified.
3. The steel jacketed steel steam directly buried thermal insulation steel pipe, this design reduces the workload of on-site construction, improves the installation efficiency, and ensures the quality of the project, which can be said to serve multiple purposes. Unqualified insulation pipes are rejected. Material properties, outer diameters, dimensional tolerances, and wall thicknesses conform to relevant national or industry standards.
To sum up, it is our summary of relevant experience on the problem of steel jacketed steel steam directly buried thermal insulation steel pipe.
