Abstract

The utility model discloses cascaded socket and spigot electric smelting connects carat pipe comprises electric smelting bellmouth, electric smelting socket and electric fuse, and wherein electric smelting bellmouth is the echelonment structure with the electric smelting socket, is equipped with bellmouth ladder platform one and bellmouth ladder platform two on the electric smelting bellmouth, is equipped with socket ladder platform one and socket ladder platform two that correspond with the electric smelting bellmouth on the electric smelting socket, and the electric fuse sets up respectively on bellmouth ladder platform one and bellmouth ladder platform two. The utility model has the advantages that: the problem of the bellmouth of current electric smelting bell and spigot joint connection carat pipe all relatively thin with the socket wall thickness, the bellmouth of connection back or socket wall thickness all bear whole tensile and bending force alone, very easily crack damaged defect is solved for the wall thickness of arbitrary department interface all is very thick reliable, is particularly suitable for the crooked heavy pipe operation and the marine long pipeline of marine engineering in drags the pipe transportation.

Description

Cascaded socket joint electrofusion connects carat pipe

Technical Field

The utility model relates to a plastic tubing, especially a cascaded socket joint electric smelting connects carat pipe.

Background

With the success of the engineering of taking out drainage pipelines from the sea of Philippine maximum coal-fired unit power stations built by three companies, namely three Navy Bureau of China, three Navy-Ching-Navy-Zhai-Navy-Chi-. However, the carat pipe in the engineering continues to be connected by electric melting socket joints adopted in traditional buried construction, the mode only has one group of electric melting wire welding processes, the bottom of the socket and the bottom of the spigot are weak points, the diversified construction mode of ocean engineering is limited, the offshore pipe dragging of less than one hundred meters of pipelines or the direct sinking of dozens of meters of pipelines can be adopted, the construction period and the comprehensive cost are extremely unfavorable, and the construction method has a space for innovation and improvement.

Disclosure of Invention

The utility model aims at overcoming the shortcoming of prior art, providing a pipeline product that can effectively improve joint strength, especially a cascaded socket joint electric smelting connects carat pipe.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a cascaded socket electric smelting connects carat pipe, comprises electric smelting bellmouth, electric smelting socket and electric fuse, and wherein electric smelting bellmouth is echelonment structure with the electric smelting socket, is equipped with bellmouth ladder platform one and bellmouth ladder platform two on the electric smelting bellmouth, is equipped with socket ladder platform one and socket ladder platform two that correspond with the electric smelting bellmouth on the electric smelting socket, and the electric fuse sets up respectively on bellmouth ladder platform one and bellmouth ladder platform two.

The utility model discloses outstanding advantage is: the problem of the bellmouth of current electric smelting bell and spigot joint connection carat pipe all relatively thin with the socket wall thickness, the bellmouth of connection back or socket wall thickness all bear whole tensile and bending force alone, very easily crack damaged defect is solved for the wall thickness of arbitrary department interface all is very thick reliable, is particularly suitable for the crooked heavy pipe operation and the marine long pipeline of marine engineering in drags the pipe transportation.

Detailed Description

As shown in fig. 1, fig. 2 and fig. 3, a stepped socket electrofusion connecting krah pipe is composed of an electrofusion socket 1, an electrofusion socket 2 and an electrofusion fuse 3, wherein the electrofusion socket 1 and the electrofusion socket 2 are in a stepped structure, a socket stepped platform I11 and a socket stepped platform II 12 are arranged on the electrofusion socket 1, a socket stepped platform I21 and a socket stepped platform II 22 corresponding to the electrofusion socket 1 are arranged on the electrofusion socket 2, and the electrofusion fuse 3 is respectively arranged on the socket stepped platform I11 and the socket stepped platform II 12. The bellmouth and the socket can be well welded together under the assistance of the inner support and the outer holding device, and after the electric melting of the pipe is finished, the thickness of the pipe wall corresponding to the bottom of the bellmouth or the bottom of the socket of the pipe is safe enough, and the pipe is good in stretch resistance and bending resistance. As shown in fig. 4, in order to ensure the welding quality and make the inner support and the outer holding device function, the conventional connection technology generally adopts a thinner socket structure to achieve better fusion, and the corresponding wall thickness of the bottom of the socket or the bottom of the spigot is thinner, so that the potential safety hazard exists, and the tensile resistance and the bending resistance are poor.

Compared with the prior art, the scheme has the advantages that: the problem of the bellmouth of current electric smelting bell and spigot joint connection carat pipe all relatively thin with the socket wall thickness, the bellmouth of connection back or socket wall thickness all bear whole tensile and bending force alone, very easily crack damaged defect is solved for the wall thickness of arbitrary department interface all is very thick reliable, is particularly suitable for the crooked heavy pipe operation and the marine long pipeline of marine engineering in drags the pipe transportation.
