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...
