Problems solved by technology

This flange is machined to grind and smooth the joint surface, so the airtightness when connecting the pipes is good, but the price of the flange is high, which increases the construction cost. In the case of connecting the pipes horizontally , it is extremely difficult to insert the bolts into the bolt holes on the lower side of the flange and fasten them, and there is a difficulty in the work.

Embodiment Construction

[0042] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0043] figure 1 Is a perspective view showing a basic embodiment of the pipe joint of the present invention, figure 1 (a) is a diagram showing the state before connecting the joint, figure 1 (b) is a diagram showing a state after the joint is connected.

[0044] This embodiment is an embodiment corresponding to the second configuration in the "Summary of the Invention" column above. It is a preferred implementation when used in a construction site such as a catchment ditch to connect multiple pipes in a horizontally placed state. the way.

[0045] This embodiment and the embodiments described later have been described as pipe joints for connecting screen tubes, but the pipes to be connected are not limited to screen tubes, and may be ordinary cylindrical steel pipes or resin pipes. . In addition, the pipe joints used in this embodiment and the embodiments described...

Abstract

The present invention provides a novel pipe joint which has the necessary and sufficient functions as a pipe joint for water supply steel pipes and the like and improves workability. The pipe joint (1) of the present invention has flange fixing bands (5, 5); and extend in a direction parallel to the pipe axis, and form a pair of plate-shaped flanges ( 6, 6), each flange is provided with connecting holes (7, 7) for inserting fastening parts, and the bands (5, 5) used for fixing the flanges make the axially outer part of the tube only from the end edge of the tube. Highlight the specified distance.

Description

Technical field [0001] The present invention relates to pipe joints, and particularly to pipe joints that are preferred as joints for steel pipes for water delivery such as steel pipes used in water wells for taking groundwater, and steel pipes for catchment ditch. Background technique [0002] As a method of connecting a plurality of pipes used as steel pipes for water supply to each other, the simplest method is to weld and connect the adjacent ends of the two pipes to be connected. However, for the welding method, although the pipes can be connected straight to each other in the case of welding in the factory, it is difficult to connect straight to the construction site such as a catchment ditch, which is prone to standard deviation and has the difficulty of poor processing accuracy. . [0003] In addition, there is another method, which is to install an external thread on one end of the two pipes to be connected, and install an internal thread on the other end, and screw one e...
