Description

Tee pipe forming apparatus

The present invention relates to a tee pipe forming apparatus for integrally forming a tee (T) in a pipe, and more particularly, to form a molding hole and to form a tee through a molding jig to trim the molding site. It is about making a series of work to be performed easily through one molding apparatus.

In general, in the piping work of a pipe for transporting a fluid such as water or oil, when the fluid transfer path of the main pipe is bifurcated, a tee (T) having a branch outlet part is provided vertically in the center of the outer circumference. In the past, such a tee was usually molded separately from the main pipe and welded or screwed to the main pipe.

However, in the case of assembling a separately manufactured tee by welding or screwing the tee, it is expensive to manufacture and manage the tee separately, and the welding and screwing of the tee is cumbersome and time-consuming. Not only will it take a lot of work, but there will be a problem that a lot of work manpower and work costs, and also stiffness of the assembly part will be a problem.

The present invention has been made in view of the conventional situation as described above, the purpose is to improve the efficiency of the piping work, as well as to reduce the parts cost and work cost, and to improve the rigidity of the branch portion The present invention provides a tee pipe forming apparatus that can easily form a tee integral pipe.
