The diameter of a tee joint body is between 219 millimeters and 1,620 millimeters; and the wall thickness of a combined bent part between a main pipe and a branch pipe is 1.25 to 1.44 times those of a main pipe interface part and a branch pipe interface part. The novel tee joint has a simple structure, and is suitable for the connecting pipeline of the 660MW-1,000MW generator set, and connection of other applicable pipelines.
Description
Technical field
The utility model belongs to a kind of tee pipe fitting that is specifically designed to supporting 660MW-1000MW generator set pipeline in pipe joint (pipe fitting) technical field.
Background technique
Along with maximization day by day, modernization and scientific and technical the advancing by leaps and bounds of power-generating industry, the technical requirements that its pipeline is connected required tee pipe fitting is also more and more higher.In known technology, existing to be used for the supporting 600MW of power plant and to connect used threeway with the pipeline of interior unit mainly be by alloy P11, P22, and P91, raw materials such as P92 adopt forging or welding or heat pressing process to make the threeway body.But limit by its structure, time-consuming length, power consumption height, because former hot-pressed three-way pipe fitting arts demand all heats, then part is suppressed with water cooling again, in cooling procedure, may cause the heavy damage of metallic gold phase constitution, crackle occurring even scrap. Forged Tee is time-consuming, the cost height. welding tee exists safety coefficient low. and yield rate is low, waste material, defectives such as working life is short, use is restricted, and especially structure can not be applicable to the technical requirements of the used threeway of 660MW-1000MW generator set connecting tube, used being restricted.
Summary of the invention
In order to overcome the deficiencies in the prior art, solve the problem that existing three-port structure can not be applicable to the used threeway technical requirements of 660MW-1000MW generator set connecting tube.The purpose of the utility model provides a kind of simple structure, and the manufacturing process simple and feasible is time saving and energy saving, and it is low to consume energy, and saves material, the yield rate height, and long service life can be applicable to the novel three-way of 660MW-1000MW of power plant and above generator set connecting tube thereof.
The technical scheme in the invention for solving the above technical problem is:
A kind of 660MW-1000MW generator set connecting tube is that diameter is 219mm-1620mm with new-type T type threeway, this threeway body, and the conjuncted turn of bilge wall thickness of its person in charge and branched pipe is person in charge's joining part wall thickness, branched pipe joining part wall thickness 1.25-1.44 a times.
Above-mentioned 660MW-1000MW generator set connecting tube is 1.1-1.4 a times of person in charge's joining part wall thickness with new-type T type threeway, described branched pipe joining part wall thickness.
Above-mentioned 660MW-1000MW generator set connecting tube is that the two sides becomes the inclined to one side plush copper formula butt joint of slope, rank shape groove in opposite directions with new-type T type threeway, the butt joint groove of described threeway body.
Above-mentioned 660MW-1000MW generator set connecting tube is with the threeway of new-type T type, it is by behind inside again oblique 10 ° of-15 ° of angles behind oblique 30 ° of angles in the mouth of pipe lateral that the two sides of described threeway body becomes the inclined to one side plush copper formula butt joint of slope, rank shape groove in opposite directions, connect the inwardly extremely inclined to one side plush copper top margin in oblique 33 ° of-40 ° of angles again, mouth of pipe inboard is to the extremely inclined to one side plush copper top margin in 15 ° of angles of outslope.
Above-mentioned 660MW-1000MW generator set connecting tube is with the threeway of new-type T type, the two sides of the described threeway body inclined to one side plush copper formula of Cheng Jiepo shape butt joint groove in opposite directions is by inside oblique 10 ° of-15 ° of angles again after 0 ° of flat stretching again, oblique 30 ° of angles in the mouth of pipe lateral, connect the inwardly extremely inclined to one side plush copper top margin in oblique 33 ° of-40 ° of angles again, mouth of pipe inboard is to the extremely inclined to one side plush copper top margin in 15 ° of angles of outslope.
Above-mentioned 660MW-1000MW generator set connecting tube is with the threeway of new-type T type, and described threeway body is to be any seamed pipe of P11, P12, P91, P92, P22, WB36, A672, B70, CL32, A106B, 20#, 16Mn, the threeway that weldless tube is made through reducing hot pressing by material.
Threeway preparation process of the present utility model is a kind of new hot-pressed three-way pipe fitting technology, change mode of heating, change the intermediate frequency local heating into, dwindle heated perimeter, use special pressure equipment that the steel pipe reducing is pressed into threeway, the whole heating of intermediate frequency, equipment flattens, company develops voluntarily special three-way heating plant local heating 950 degree-1050 degree, with progressively modification moulding of heating part, distortion place perforate, special grinding apparatus draw, matched moulds, support mouth, machining.Because of above technology does not need water cooling, external diameter has specialized mould, so solved all problems of old heat pressing process, and outward appearance forming, the conjuncted turn of bilge wall thickness of the person in charge and branched pipe is person in charge's joining part wall thickness, branched pipe joining part wall thickness 1.25-1.44 a times, it thickens obviously, do not increase at raw material can reach under the situation of too many wall thickness and need the thickness that strengthens, the resultant metal metallographic structure is excellent, the yield rate height, raw material are economized, and advantages such as long service life can replace welding, the original production technology of hot pressing also can recommend to replace forging to usefulness side.
When the utility model uses, the same with existing threeway, be connected and constitute pipeline between the tube and tube.
Because technique scheme has been adopted in the utility model design, has solved the problem that existing three-port structure can not be applicable to the used threeway technical requirements of 660MW-1000MW generator set connecting tube effectively.Show that through testing result on trial for several times it compared with prior art has simple structure, the manufacturing process simple and feasible, time saving and energy saving, it is low to consume energy, and preparation process need not cooled off, external diameter has specialized mould, save material, yield rate height, beneficial effects such as long service life, be applicable to the generator set connecting tube that 660MW-1000MW and 1000MW thereof are above, and the connection of other suitable conduit.
