Abstract
The utility model relates to a part of a chemical pipeline and particularly relates to a pipeline assembly at the root part of an integral high-temperature pressure instrument. The pipeline assembly comprises a flange, a short pipe and a valve (can also comprises a bent pipe). The pipeline assembly is characterized in that the pipeline assembly further comprises a reinforcing pipe saddle, wherein a thin pipe is arranged at the upper end of the pipe saddle, and a thick pipe is arranged at the lower end of the pipe saddle. The pipeline at the root part of the integral pressure instrument is prefabricated in a factory, that is to say, the pipeline is welded and thermally treated in the factory; and a valve inner piece is mounted after the thermal treatment. The pipeline assembly solves the problems as follows: firstly, the breakage due to poor strength and the overgreat deformation of the connected part between the pressure instrument and a main pipe is poor at high temperature is avoided; and secondly, a sealing inner piece of the valve is not influenced by thermal treatment, the leakage due to deformation of the sealing inner piece of the valve caused by the thermal treatment in a construction field is overcome and the safe operation of a high temperature overheat steam pipeline of a dehydrogenation reaction zone is ensured.
Description
Technical field
The utility model relates to the parts of chemical pipeline, particularly a kind of integral high-temperature pressure instrument root conduit assembly.
Background technique
Integral high-temperature pressure instrument root conduit assembly now is mainly used in the core apparatus district-dehydrogenation reaction zone high temperature steam pipeline of production of styrene device.Distinguish from structure, it can be divided into the integral high-temperature pressure instrument root conduit assembly of no bend pipe and the integral high-temperature pressure instrument root conduit assembly of bend pipe is arranged.
As shown in Figure 1, the integral high-temperature pressure instrument root conduit assembly of no bend pipe is first weldolet A4 on main pipe A5, and weld nipple A2 welds valve A3 more again, welds another short tube A2 again, again welded flange A1.Flange A1 is connected with pressure instrument.These welding are all carried out at the construction field (site), need to carry out the high temperature postweld heat treatment after the welding.
As shown in Figure 2, the integral high-temperature pressure instrument root conduit assembly that bend pipe is arranged is the welding-Saddle B5 of elder generation, weld nipple B2 again on main pipe B6, weld ell B4 welds in addition-short tube B2 more again, welds valve B3 again, a welding short tube B2 more again, welded flange B1 more at last.Flange B1 is connected with pressure instrument.These welding are also all carried out at the construction field (site), need to carry out the high temperature postweld heat treatment after the welding.
Said structure has following shortcoming in welding operation with in using.
1) operating temperature is very high, and the general operation temperature is at 870～920 ℃.So the selection of material also special (UNS N08811 INCOLOY 800H or UNS N08811 INCOLOY 800HT), because the operating temperature height, pipe deforming is big during work.
2) all weld seams need the high temperature postweld heat treatment.
Because vinyl benzene superheat steam pipeline and These characteristics that material has, adopt prior art can have two problems: a) under the effect of pressure instrument load and under the high temperature condition, the distortion of assembly short tube is very big, causes the weld seam easy-rupturing between short tube and the Saddle.B) after the field welding during high-temperature heat treatment, make the valve base sealing distortion in the assembly valve wherein, and cause valve leak.
The model utility content
The purpose of this utility model is to provide a kind of integral high-temperature pressure instrument root conduit assembly, the problem that solves is: 1) Yin Gaowen downforce instrument be responsible for the joint insufficient strength, distortion is excessive and the fracture that causes, 2) make the not influence of heat-treated of Sealing of valve, solved because of job site heat treatment causes valve seal internals distortion and cause leakage, it has guaranteed the safe operation of dehydrogenation reaction zone hyperthermia and superheating steam line.
For achieving the above object, the utility model is to realize like this.
A kind of integral high-temperature pressure instrument root conduit assembly, it comprises flange, short tube and valve, it is characterized in that: it comprises that also a upper end is that tubule, lower end are the reinforced base of extra heavy pipe; Described reinforced base upper end connects valve one end, and this valve the other end connects an end of short tube, and the other end of this short tube is adpting flange then.
A kind of integral high-temperature pressure instrument root conduit assembly (having bend pipe) with bend pipe, it comprises flange, two short tubes, valve and bend pipe, it is characterized in that: it comprises that also a upper end is that tubule, lower end are the reinforced base of extra heavy pipe; One end of described reinforced base upper end bridge piece, the other end of this bend pipe connects an end of first short tube, and the other end of first short tube connects an end of valve, and the other end of valve connects an end of second short tube, and the other end of second short tube is adpting flange then.
By said structure also compared with prior art, advantage of the present utility model is:
The utility model is by adopting special reinforced base with pressure instrument root pipeline, and the integrated piping assembly is in manufacturing works' welding, heat treatment, avoid the leakage of valve in fracture that pressure instrument root strength deficiency causes and the assembly, guaranteed the safe operation of dehydrogenation reaction zone hyperthermia and superheating steam line.
