Abstract

The utility model relates to a five-way pipe fitting which comprises a main pipe; pipe caps are capped at two ends of the main pipe; one side of the main pipe is provided with an input pipe, and the other side of the main pipe is provided with four rear cooling device connecting pipes in parallel arrangement; the thickness of the main pipe is 9.53-25.40mm; and the intervals of the rear cooling device connecting pipes are 1000-3000mm. The technical problems that the existing five-way pipe fitting consisting of five standard three-way pipe fittings is mainly adopted, the five-way pipe fitting and four pipe openings connected with rear cooling devices cannot be configured uniformly and symmetrically, and the intervals of the four pipe fittings of the rear cooling devices are small, and five standard three-ways cannot be configured without enough space and the like are solved, four pipe openings connected with the rear cooling devices can be configured uniformly, and can be regulated according to pipe opening intervals of the rear cooling devices so as to meet the requirements of connection with the rear cooling devices.

Description

A kind of five-way tubing

Technical field

The utility model relates to the parts of petrochemical pipe, particularly a kind of five-way tubing.

Background technique

The rectifying column aftercooler is a kind of common heat transmission equipment in the petrochemical plant, and its import has 1,2 and 4 minute.Wherein, the present typical structure of conduit component of its import of aftercooler of 4 imports and mounting type are as shown in Figure 1, generally need to use parts to comprise equal tee 1(1), reducing tee 2(4), pipe cap 3(2) form, these standard pipe fitting job sites weld together the composition five-way tubing, and 4 mouths of pipe in this pipe fitting bottom are connected with 4 imports of aftercooler.

Styrene Process phenyl ethylene rectification tower aftercooler main feature:

1) import has 4, and 4 imports require to arrange symmetrically.

2) 4 import mouth of pipe spacings are little, and the spacing of this import mouth of pipe is 1000 ~ 3000mm, fail to lay down five standard tee pipe fittings.

Because phenyl ethylene rectification tower These characteristics that aftercooler has, adopt prior art can have two problems: 4 mouths of pipe that 1) are connected with aftercooler can't be arranged symmetrically; 2) 4 mouth of pipe spacings of aftercooler are little, do not have enough spaces to arrange five standard threeways.

The model utility content

The purpose of this utility model is to provide a kind of five-way tubing, when mainly solution has the five-way tubing use of five standard tee pipe fittings compositions of main employing now, 4 mouths of pipe that are connected with aftercooler can't be arranged symmetrically, and 4 mouth of pipe spacings of aftercooler are little, there are not enough spaces to arrange five technical problems such as standard threeway, it can be evenly arranged 4 mouths of pipe that are connected with aftercooler, and 4 mouths of pipe can be according to the mouth of pipe spacing adjustment of aftercooler, to satisfy the requirement that is connected with aftercooler.

For achieving the above object, the utility model is to realize like this.

A kind of five-way tubing is characterized in that: it comprises a supervisor, and these supervisor two ends add is stamped pipe cap, and this is responsible for a side and has a supplying tube, opposite side and have 4 aftercoolers that be arranged in parallel and take over; This supervisor's thickness is 9.53 ~ 25.40mm, and the spacing that this aftercooler is taken over is 1000 ~ 3000mm.

By said structure also compared with prior art, the utility model has the advantage of: five standard tee pipe fittings of routine are replaced with a welding five-way tubing, effectively satisfied the specific (special) requirements that 4 import mouths of pipe of aftercooler are arranged; And the moulding that is prefabricated in the factory of whole pipe fitting, and the mouth of pipe length that 4 of bottoms are connected with aftercooler can directly be connected with the aftercooler mouth of pipe with requiring to adjust length, reduced the welding engineering amount of job site.

The utility model is mainly used in Styrene Process nucleus-phenyl ethylene rectification district, on the inlet pipeline of phenyl ethylene rectification tower aftercooler, and on other similar equipment importation or the outlet conduit.

Description of drawings

Fig. 1 is the structural representation of existing five-way tubing.

Among the figure: 1-equal tee, 2-reducing tee (4), 3-pipe cap (2).

Fig. 2 is structural representation of the present utility model.

Among the figure: the 2-pipe cap, the 4-supervisor, the 41-supplying tube, the 42-aftercooler is taken over.

Embodiment

See also Fig. 2, the utility model discloses a kind of five-way tubing.As shown in the figure: it comprises a supervisor 4, and this is responsible for 4 two ends and adds and be stamped pipe cap 2, and this is responsible for 4 one sides and has a supplying tube 41, opposite side has 4 aftercoolers that be arranged in parallel and takes over 42; This supervisor's 4 thickness is 9.53 ~ 25.40mm, and the spacing of this aftercooler adapter 42 is 1000 ~ 3000mm.

Characteristics of the present utility model are: supervisor's 4 integral body of 1) using thicken reinforcement, and 4 mouths of pipe of bottom can be arranged symmetrically.2) whole pipe fitting volume is little, and 4 aftercoolers that the bottom is connected with aftercooler are taken over 42 and can be adjusted according to the mouth of pipe spacing of aftercooler, thereby satisfies the pipeline connection request of 4 import aftercoolers.

The utility model is used for the refining district rectifying column aftercooler inlet pipeline of Styrene Process, has satisfied the requirement that the aftercooler inlet pipeline is arranged symmetrically, has guaranteed rectifying column and aftercooler stable operation.

Claims

1. five-way tubing is characterized in that: it comprises a supervisor (4), and this supervisor (4) two ends add is stamped pipe cap (2), and these supervisor's (4) one sides have a supplying tube (41), opposite side has 4 aftercoolers that be arranged in parallel and takes over (42); This supervisor's (4) thickness is 9.53 ~ 25.40mm, and the spacing that this aftercooler is taken over (42) is 1000 ~ 3000mm.
