AI Technical Summary
Existing metal steel pipes cannot achieve continuous online operation for each pipe in the solid solution process. They are prone to oxidation and deformation of large-diameter steel pipes due to misalignment of the inlet, and it is difficult to remove air from the inner wall.
An online solid fusion connector for metal steel pipes was designed, including a pipe body and an arc-shaped head. It has a first through hole and a second through hole. The outer diameter of the connection transition section is larger than the outer diameter of the pipe body. The arc-shaped head gradually narrows to guide and vent air, thus preventing deformation and oxidation of the steel pipe.
It enables continuous online operation of large-diameter metal steel pipes one by one, avoiding misalignment and oxidation of steel pipes, and ensuring smooth entry and deformation prevention of steel pipes during the solidification process.

Abstract
Description
Metal pipe in-line solution bonding connector Technical Field
[0001] This invention relates to in-line solution bonding connectors for metal steel pipes. Background Technology
[0002] Existing metal steel pipes cannot be continuously operated online one by one during the solid solution process. When entering the solid solution furnace, misalignment of the inlet is likely to occur, and air is not easily vented from the inner wall of the metal steel pipe, which can easily cause oxidation.
[0003] When performing online solidification of large-diameter metal steel pipes, the existing design of the pipes at both ends can cause the large-diameter metal steel pipes to twist and deform when bent or turned due to the presence of the pipes. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an online solid solution connector for metal steel pipes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal steel pipe online solid fusion connector, including a pipe body and a connector head, one end of the pipe body is connected to one end of the connector head, the other end of the connector head is provided with a first through hole, the first through hole is connected to the cavity inside the pipe, the side wall of the connector head is provided with a second through hole, which is connected to the cavity inside the pipe, and the other end of the pipe body is provided with an opening, which is connected to the cavity inside the pipe.
[0006] Furthermore, the connector is an arc-shaped head.
[0007] Furthermore, a connecting transition section is provided between one end of the tube body and one end of the arc-shaped head, and the connecting transition section is cylindrical.
[0008] Furthermore, a second through hole is provided on the side of the connecting transition section.
[0009] Furthermore, the outer diameter of the connecting transition section is larger than the outer diameter of the pipe body.
[0010] Furthermore, the outer diameter of one end of the arc-shaped head is consistent with the outer diameter of the connecting transition section, and gradually decreases towards the other end of the arc-shaped head.
[0011] Furthermore, the curved head is a hemisphere.
[0012] Furthermore, the connector can be frustum-shaped, conical, T-shaped, or other tapered shapes.
[0013] The beneficial effects of this invention are: simple structure, enabling continuous online operation of large-diameter metal steel pipes one by one, avoiding misalignment of the next metal steel pipe with the solidification furnace inlet; it has a guiding function; the first through hole connects to the large-diameter metal steel pipe in front, and the second through hole connects to the solidification furnace, allowing hydrogen to enter rapidly after entering the solidification furnace. The hydrogen enters the inner wall of the metal steel pipe along the connector and discharges the air from the inner wall of the metal steel pipe, preventing oxidation of the inner wall of the metal steel pipe; it avoids bending and deformation of the large-diameter metal steel pipe when heated, and the connection angle between two adjacent large-diameter metal steel pipes can be adjusted arbitrarily.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to Figures 1-7 in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0022] Referring to Figures 1-4, the metal steel pipe online solid solution connector includes a pipe body 1 and an arc-shaped head 2. One end of the pipe body is connected to one end of the arc-shaped head, and the other end of the arc-shaped head is provided with a first through hole 3, which communicates with the inner cavity 4 of the pipe. The side wall of the arc-shaped head is provided with a second through hole 5, which communicates with the inner cavity of the pipe. The other end of the pipe body is provided with an opening 6, which communicates with the inner cavity of the pipe.
[0023] The metal pipe online solid solution connector has a connecting transition section 7 between one end of the pipe body and one end of the arc-shaped head. The connecting transition section is cylindrical.
[0024] The metal pipe online solid solution connector has a second through hole located on the side of the connection transition section.
[0025] Metal steel pipe online solid solution connector, the outer diameter of the connection transition section is larger than the outer diameter of the pipe body.
[0026] The metal pipe online solid solution connector has an outer diameter at one end of the arc-shaped head that matches the outer diameter of the connection transition section, and gradually narrows towards the other end of the arc-shaped head.
[0027] Metal pipe in-line solid solution connector, the arc-shaped head is hemispherical.
[0028] The outer diameter of the tube is matched with the inner diameter of the large-diameter metal steel pipe.
[0029] The process for online solution treatment of individual metal steel pipes is as follows:
[0030] Step 1: The large-diameter metal steel pipe is conveyed into the solidification furnace through a conveying device for solidification treatment;
[0031] Step 2: The first end of the large-diameter metal pipe is connected to the end of the large-diameter metal pipe in front through an online metal pipe solidification connector. The large-diameter metal pipe in front follows the large-diameter metal pipe into the solidification furnace for solidification treatment through a conveying device. This process is repeated, and several metal pipes are continuously fed into the solidification furnace for solidification treatment.
[0032] Step 3: After the front large-diameter metal steel pipe has been solidified in the solidification furnace, separate the rear large-diameter metal steel pipe and remove the online solidification connector of the metal steel pipe. Repeat the operation in sequence.
[0033] The metal pipe online solid solution connector uses hydrogen gas introduced into the solid solution furnace. The hydrogen gas enters the metal pipe through the gas inlet and expels the air inside the metal pipe.
[0034] It can achieve continuous online operation for each branch.
[0035] Metal steel pipe online solid solution connector, the pipe body 1 is tapered.
