Abstract

The utility model discloses a novel small-area high-temperature and high-pressure pipeline protection plate. On the basis of a protection technology for high-temperature and high-pressure pipelines, the problems of other technologies are solved. A novel protection plate is fixed on a high-temperature pipeline; stress relaxation grooves are formed in the novel protection plate; welding seams are formed between the high-temperature pipeline and the novel protection plate; the stress relaxation grooves are U-shaped; the width of each stress relaxation groove is equal to the thickness of the protection plate; the length of each stress relaxation groove is equal to that of the welding seam; the stress relaxation grooves correspond to the welding seams; the distance between each stress relaxation groove and the edge of the protection plate is required to be greater than the thickness of the protection plate.

Description

A kind of zonule high-temperature and pressure pipeline Novel fender

Technical field: the utility model relates to the resist technology on high temperature, high pressure pipe line, especially a kind of zonule high-temperature and pressure pipeline Novel fender.

Background technique: in chemical plant installations, much high temperature, high pressure, inflammable, explosive e-quipment and pipe adopt the form of support and suspension bracket to fix in a large number, support, suspension bracket and backplate are welded and fixed, and backplate and pipeline welding are fixed, thereby play the effect of fixed support pipeline.Support, suspension bracket and backplate will bear very large intricate stress, the more important thing is, pipeline bears by contrast various stress and duty ratio backplate are much higher, pipeline not only bears pressure and the corrosion of interior media, also to bear the welding residual stress with backplate weld, so crackle often appears in high-temperature and pressure pipeline and backplate weld in chemical plant installations (near pipeline one side), cause dielectric leakage and device to stop.

Summary of the invention: the purpose of this utility model is to provide simple in structure, easy to operate a kind of zonule high-temperature and pressure pipeline Novel fender, it has overcome the problem that other technology exists, and the purpose of this utility model is achieved in that it is on high-temperature pipe, to fix a Novel fender; On Novel fender, there is stress to relax groove; In the middle of high-temperature pipe and Novel fender, there is weld seam; It is U-shaped that stress relaxes groove, the thickness that the width of stress mitigation groove is backplate; The length that the length of stress mitigation groove is weld seam, and corresponding with every section of weld seam; The distance that stress relaxes slot length and backplate edge should be greater than backplate thickness.

Meaning of the present utility model is: eliminate cleverly most of welding residual stress, in the time that bringing into operation intensification, high-temperature and pressure pipeline reduces temperature difference stress (between pipeline and backplate), play the buffer function between support, suspension bracket and pipeline, avoided stress to concentrate the pipeline crack causing.

Brief description of the drawings: Fig. 1 is the structural representation of a kind of zonule high-temperature and pressure pipeline Novel fender, in figure 1, Novel fender 2, stress relax groove 3, weld seam 4, high-temperature pipe

Fig. 2 is the side view of a kind of zonule high-temperature and pressure pipeline Novel fender, in figure 1, Novel fender 4, high-temperature pipe

Embodiment: embodiment 1, the utility model are to fix a Novel fender 1 on high-temperature pipe 4.

Embodiment 2, on Novel fender 1, have stress relax groove 2; In the middle of high-temperature pipe 4 and Novel fender 1, there is weld seam 3.

It is U-shaped that embodiment 3, stress relax groove 2, and the width that stress relaxes groove 2 is the thickness of backplate 1; The length that stress relaxes groove 2 is the length of weld seam 3, and corresponding with every section of weld seam; Stress relaxes the length of groove 2 and the distance at backplate 1 edge is greater than backplate 1 thickness.
