Description

Taped and Threaded Pipe Fittings

The present invention relates to a pipe fitting. Specifically, when pipes are directly connected when the diameters of the pipes to be connected are the same, when pipes are connected using reducer pipe fittings when the diameters of the pipes to be connected are different, the pipes may be flanged. Are connected to each other, when the pipes are connected in a-shape using an elbow pipe fitting and when three pipes are connected using a T-shaped fitting, four pipes are connected to each other using a + pipe fitting. The present invention relates to a pipe fitting having an inclined portion and a threaded portion for connecting a plurality of pipes and the like using a multi-shaped pipe fitting.

Until now, pipe fittings connecting pipes to each other include convex and concave slopes at the ends of the pipes, and the pipes are joined together using an adhesive, or the pipes are joined together using a flange manufactured by attaching the pipes, or The pipes are joined by mechanically joining or connecting adhesives at the same time by connecting the whole threaded part in parallel with an outer side. In addition, in order to prevent leakage at the joints of pipes, the sealing property is improved by wrapping the composite material on the outside of the joints or inserting an O-ring at the part where the pipes contact each other.

In such a conventional joining method, in the case of simply joining with an adhesive using only an inclined part, the joining process is relatively simple and easy to install. However, the joining part is weakened by a light load, and thus the pipe contents may leak. . In the case of having a screw part in the whole connection part, it is not only expensive to manufacture because the thread part is long, but also requires a lot of manpower when installing, and an adhesive must be separately used to prevent leakage through the thread part. The method of enclosing the joints externally is not only complicated in the installation process, but also has a problem of ensuring sealing against leakage. In addition, the installation of O-rings on the pipe contacts is cumbersome and there is still concern about the leakage of the contents.

The present invention is designed to solve the problems of the conventional pipe fittings as described above and the problems of the pipe connection method.

According to the present invention, pipe fittings are used for all types of pipes, such as factory pipes, gas pipes, oil pipes, building pipes, power plant pipes, apartment pipes, water pipes, etc. The inclined part is made up of the inclined part and the threaded part, and the inclined part prevents contact between the screw part and the pipe sides during assembly and disassembly of the screw connection part, thereby improving workability during assembling and detaching the pipe, and applying and bonding adhesive to leak the pipe contents. Prevent it at the source. In addition, the screw part forms a mechanical joint force when joining the pipes, and when the protrusion of the second pipe is inserted into the connection part of the first pipe, the screw part is configured to press the pipe connection part by physical binding force to prevent adhesive force due to the adhesive applied to the inclined part. Not only does it improve, it also prevents material inside the pipes from leaking to the outside.

In addition, the physical binding force of the screw portion and the adhesive force by the adhesive of the inclined portion to resist the tensile force that may occur in the pipe pipe.

In the present invention, as an embodiment of the pipe fitting, by simply providing a protrusion and a connection to the pipe to be connected, it is easy to join the pipe, prevent the leakage of the contents, characterized in that it can resist the tensile force of the pipe Pipe fittings with ramps and threads are provided.

In addition, in the present invention, there is also provided a pipe fitting for installing a concave joint in a flange, a protrusion in a pipe, and installing a slope and a screw in the joint to pre-mount the pipe to the flange, and connect the flanges to each other to connect the pipe. .

In the present invention, reducer pipe fittings are also provided that allow pipes to be connected to each other using separate reducer pipe fittings when the diameters of the pipes to be connected are different.

In the present invention, there is also provided an albow, T- or + -shaped pipe fitting which allows the pipe to be connected when the pipe is connected in a-, T- or + -shape.

In one embodiment of the pipe fittings, the pipe fittings are made of a composite material made by impregnating a reinforcing fiber such as structural steel, aluminum, and glass fibers, aramid fibers, etc. with a resin such as polyester, vinyl ester, epoxy, phenol, etc. Characteristic pipe fittings are provided.
