Description
Technical Field
The utility model relates to a compound steel pipe technical field specifically is a special coating compound steel pipe of fire control.
Background
The fire-fighting internal and external epoxy coating composite steel pipe is made of modified heavy-duty epoxy resin powder, has excellent chemical corrosion resistance, fundamentally solves the problems of rusting and corrosion on the surface, scaling on the inner wall and the like of similar products after long-term use, avoids the phenomenon of influencing the use due to internal blockage, and greatly prolongs the service life of the fire-fighting special pipe. As the flame-retardant material is added into the coating material, the temperature resistance of the product is improved compared with other similar products. Therefore, the use is not affected even when the ambient temperature rises sharply. The service life and performance of the internal and external coating fire fighting pipe are much better than those of the galvanized pipe.
However, the analysis shows that the existing special coating composite steel pipe for fire fighting has the following defects: the outer side of the pipeline is polluted and corroded from the outer side, so that the pipeline needs to be repaired at regular time, the service life of the pipeline is reduced, and the pipeline generates friction force when powder is conveyed by the pipeline, so that the pipeline generates heat, therefore, the invention provides the special coating composite steel pipe for fire fighting to solve the problems.
