Abstract
The utility model discloses a main part preliminary treatment spare of petroleum pipeline connecting piece, comprising a main body, the main part is equipped with the strengthening rib that two piece at least equidistance were arranged on the lateral part opening, the length direction of strengthening rib and main part mutually perpendicular. The utility model arranges a plurality of reinforcing ribs at the side opening of the main body, so that the prepared main body pretreatment piece can not deform under the action of the reinforcing ribs, and the reinforcing ribs are cut off after heat treatment, thereby preventing the main body from deforming caused by the heat treatment; and moreover, the hot rolled steel with better toughness is adopted, so that the shrinkage cracking tendency of the R angle is effectively reduced.
Description
Technical Field
The utility model relates to a precision casting field especially relates to a main part preliminary treatment spare of petroleum pipeline connecting piece.
Background
The butt joint of petroleum pipeline adopts dedicated connecting piece, mainly is used for butt joint location between the pipe and the fixed positioning of control line, and this connecting piece includes main part and cutting ferrule, and the main part is formed by precision casting, and the surface of requirement foundry goods and the slotted hole must not have the crackle, however, because the length of main part is longer, the main part of present conventional casting method casting can produce the deformation, and because the slotted hole of main part is more, the crack after the inside R angle is detected a flaw, if carry out great weld repair and polish, then cause and weld repair the back deformation.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides a petroleum pipeline connecting piece's main part preliminary treatment piece, main part preliminary treatment piece set up many strengthening ribs through the lateral part opening part in the main part to make the main part preliminary treatment piece that makes can not take place to warp under the effect of strengthening rib, this strengthening rib amputates after thermal treatment, thereby prevent that thermal treatment from arousing the main part to warp, effectively solved the problem pointed out among the background art.
The utility model adopts the technical proposal that:
the main body pretreatment piece of the petroleum pipeline connecting piece comprises a main body, wherein at least two reinforcing ribs which are arranged at equal intervals are arranged on an opening on the side part of the main body, and the reinforcing ribs are vertical to the length direction of the main body.
Preferably, the main body and the reinforcing ribs are integrally formed after being smelted by using hot rolled steel with good toughness.
Preferably, the number of the reinforcing ribs is 3, and the end faces of the two ends of each reinforcing rib are circular.
The utility model discloses following beneficial effect has:
1. the main body pretreatment piece is provided with the plurality of reinforcing ribs at the side openings of the main body, so that the prepared main body pretreatment piece cannot deform under the action of the reinforcing ribs, and the reinforcing ribs are cut off after heat treatment, so that the main body is prevented from deforming due to the heat treatment;
2. the reinforcing ribs are vertical to the length direction of the main body, so that the supporting effect of the reinforcing ribs on the main body can be improved, and the deformation prevention capability is improved;
3. the end faces of the two ends of the reinforcing rib, which are connected with the side opening, are circular, so that the cutting difficulty can be reduced when the reinforcing rib is cut after the heat treatment is finished, and the direction deviation is not easy to generate during cutting;
4. and the hot rolled steel with better toughness is adopted, so that the shrinkage crack tendency of the R angle is effectively reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following detailed description of specific embodiments thereof, which is illustrated in the accompanying drawings.
Example 1
As shown in figure 1, the main body pretreatment piece of the petroleum pipeline connecting piece comprises a main body 1, wherein at least two reinforcing ribs 3 which are arranged at equal intervals are arranged on a side opening 2 of the main body 1, and the reinforcing ribs 3 are vertical to the length direction of the main body 1.
The main body 1 and the reinforcing ribs 3 are integrally formed after being smelted by hot rolled steel with better toughness.
3 reinforcing ribs have 3, the terminal surface at 3 both ends of reinforcing rib is circular.
The utility model discloses owing to set up strengthening rib 3 in lateral part opening 2 department, when carrying out thermal treatment, because strengthening rib 3's effect, main part 1 is difficult for producing and is out of shape, accomplishes the back at thermal treatment, amputates strengthening rib 3 again to the main part 1 that greatly reduced made produces the degree of warping, promotes main part 1's quality, and has adopted the better hot rolled steel of toughness, has effectively reduced the shrinkage crack tendency at R angle.
