Abstract
The utility model discloses an enhanced polyurethane composite steel pipeline, which belongs to a composite pipeline, in particular to a composite steel pipeline with an antisepticising durable layer lined inside the pipelines. The enhanced polyurethane composite steel pipeline comprises a steel pipe and a polyurethane layer, which is characterized in that a CHEMLOK glue layer is arranged between the inner wall of the steel pipe and a polyurethane pouring. A testing result shows that the new enhanced polyurethane composite steel pipeline of the utility model improves more than 30% in the technical targets of the pull-off strength, the shearing strength and the racking strength compared with the prior polyurethane composite steel pipe without the CHEMLOK glue layer, which has good economic benefits and social benefits.
Description
Technical field
The utility model belongs to the Composite Steel pipeline that a kind of multiple tube, particularly pipe lining have the anticorrosion antiwear layer.
Background technique
For the anticorrosion antiwear that improves pipeline decreases ability, people are usually at the inside liner of the inner compound one deck anticorrosion antiwear better performances of steel pipeline, progressively the polyurethane composite steel tube of development is exactly a kind of multiple tube of better performances in recent years, but because the adhesive strength of polyurethane and steel pipe inwall is big inadequately, its working life is shorter.
The model utility content
The purpose of this utility model provides a kind of technological scheme of new polyurethane composite steel tube of the adhesive strength of strengthening polyurethane and steel pipe inwall.
The technical solution of the utility model is that a kind of reinforced polyurethane composite steel tube comprises steel pipe, polyurethane layer, it is characterized in that: the Kai Muluoke adhesive layer is arranged in the middle of steel pipe inwall and cast polyurethane layer.
Since in the utility model the steel pipe inwall scribble the Kai Muluoke adhesive layer on this basis again the cast polyurethane layer can improve the adhesive strength of steel pipe and polyurethane layer greatly, the testing result of professional detection department sees the following form:
| The polyurethane composite steel tube | Reinforced polyurethane composite steel tube | |
| Pull-off strength (MPa): | 15-32 | 20-40 |
| Shear strength (MPa): | 15 | 20 |
| Peeling strength KN/M): | 12 | 16 |
Above-mentioned testing result shows that novel reinforced polyurethane composite steel tube that the utility model provides all improves more than 30% in technical order such as pull-off strength, shear strength, peeling strength and original polyurethane composite steel tube of not opening order Lip river gram adhesive layer, has good economic benefit and social benefit.
