Description

Technical Field

[0001] The utility model belongs to the technical field of pipe end face sealing protection, and specifically relates to a PSP steel-plastic composite pressure pipe end face sealing device. Background Art

[0002] The steel-plastic composite pressure pipe is made of welded steel pipe as the middle layer, and the inner and outer layers are made of polypropylene. The inner and outer layers and the welded steel pipe are bonded and compounded with special hot melt adhesive, and the pipe is compounded into an integrated pipe by extrusion molding. If oxygen and water vapor enter the composite interface, the welded steel pipe will be corroded, and the bonding between the hot melt adhesive and the welded steel pipe will fail, and the inner and outer plastic layers and the welded steel pipe will be delaminated, causing the pipe to fail.

[0003] In the prior art, the inner and outer layers themselves can block oxygen and water vapor from contacting the welded steel pipe, but the exposed end face of the welded steel pipe at the pipe port will directly contact oxygen and water vapor, causing oxidation corrosion to the end face of the pipe, reducing the quality of the pipe, affecting the service life of the steel, and having poor practicality.
