Abstract

The invention provides a steel pipe inner and outer plastic dipping production system. The steel pipe inner and outer plastic dipping production system comprises a steel pipe inner wall feeding device(1), a first steel pipe fixing device (2), a steel pipe outer wall feeding device (3), a second steel pipe fixing device (4) and a base (5), wherein the first steel pipe fixing device (2) and the second steel pipe fixing device (4) are arranged at two opposite ends of the base (5) respectively, the first steel pipe fixing device (2)and the second steel pipe fixing device (4) clamp the steel pipesin the length direction of the steel pipes; the steel pipe inner wall feeding device (1) is inserted into the steel pipes (6) to dip the inner walls of the steel pipes(6); the steel pipe outer wall feeding device (3) is located above the first steel pipe fixing device (2) and the second steel pipe fixing device (4), and the outer walls of the steel pipes are subjected to plastic dipping. The system has the advantages that the construction time is short, and the utilization rate of the plastic dipping material is high.

Description

technical field [0001] The invention relates to the technical field of steel pipe anticorrosion, in particular to a production system for dipping inside and outside of steel pipes. Background technique [0002] Metal corrosion has caused serious economic losses to human beings. According to foreign data, for every 10 tons of steel products, about 3 tons are scrapped due to corrosion. Therefore, in order to reduce the economic loss caused by corrosion, people continue to research and explore new anti-corrosion technology. [0003] In order to prevent corrosion, methods such as fiberglass, plastic lining, rubber lining, brushing various anti-corrosion coatings, stainless steel have occurred in the prior art for many years. But there are also defects of one kind or another, such as the strength of FRP under long-term ultraviolet radiation is not strong enough and easy to deform. Traditional plastic lining can only be used as a single-layer lining, and cannot be used for inte...
