Abstract
The utility model relates to a kind of 90o raised line screw thread bend pipe, comprises 90o bend pipe; It is characterized by it also comprise connection straight section, fixing bulge loop and strengthen raised line; Be connected with a connection straight section at 90o bend pipe two ends respectively by fixing bulge loop, be provided with some reinforcement raised lines at 90o bend pipe outer wall, the direction strengthening raised line setting is identical with the axial direction of 90o bend pipe.The utility model has the advantage that can improve piping Security.
Description
Technical field
The utility model relates to a kind of 90o bend pipe, particularly relates to a kind of 90o raised line screw thread bend pipe.
Background technique
90 ° of high pressure elbow coupling pipe fittings are the heavy connections in power plant, chemical industry, oil and pipeline transport, are also weak links outstanding in piping, and the reliability of pipeline determines primarily of the ability to work of elbow; The ability to work of elbow is relevant with the stress phase residing for it, surveys discovery as calculated, and the stress of elbow arcing point externally carries responsive especially; These are outer carries the additional external force that the change, piping vibration and suspension and support operation irregularity etc. that are mainly derived from (not comprising interior pressure and deadweight etc.) piping tube metal heat expansion in starting process cause; Elbow arcing point is stress discontinuity point in piping, namely the stress value of this point is greater than the initial segmental arc of elbow of its both sides and the stress value of straight part, in fact alternate load is subject in its long-term starting and stopping process of steam piping, its butt welding mouth intensity is totally unfavorable, after long duration of action, weld bond easily forms crackle or destruction, makes to occur insecurity in piping.
Summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is to provide a kind of 90o raised line screw thread bend pipe that can improve piping Security.
Technology contents of the present utility model is, 90o raised line screw thread bend pipe, comprises 90o bend pipe; It is characterized by it also comprise connection straight section, fixing bulge loop and strengthen raised line; Be connected with a connection straight section at 90o bend pipe two ends respectively by fixing bulge loop, be provided with some reinforcement raised lines at 90o bend pipe outer wall, the direction strengthening raised line setting is identical with the axial direction of 90o bend pipe.
The utility model is compared with prior art had is a little: to be connected at the two ends place of 90o bend pipe by fixing bulge loop and arrange a connection straight section and be provided with some reinforcement raised lines at bend pipe outer wall, improve the stress ability to bear of bend pipe, thus the ability making piping bear alternating stress increases, thus improve piping Security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in Figure 1,90o raised line screw thread bend pipe, comprises 90o bend pipe 1; It is characterized by it also comprise connection straight section 2, fixing bulge loop 3 and strengthen raised line 4; Be connected with a connection straight section 2 at 90o bend pipe 1 two ends respectively by fixing bulge loop 3, be provided with some reinforcement raised lines 4 at 90o bend pipe 1 outer wall, the direction strengthening raised line 4 setting is identical with the axial direction of 90o bend pipe 1.
