Abstract

PURPOSE: A pipe and piping member are provided to reduce the fault rate and to improve the workability at a working field by aligning pipes with a precise angle based on an angle reference point formed in the pipe and piping member. CONSTITUTION: An angle reference line is formed in a pipe(100). That is, four 90 angle lines(102) and one 45 angle line(101) is formed in the pipe(100). The angle lines(101,102) are linearly formed along the pipes. An elbow(200) and a T-joint(300) provided for connecting the pipes have four 90 angle lines(102), so that the pipes can be precisely connected to each other. Since the pipes can be precisely aligned to each other with a precise angle, the fault rate of the piping work can be reduced and the workability thereof can be improved.

Description

Pipe and piping materials with connection angle reference points

Although plumbing works such as buildings, houses, buildings, aircraft, ships, automobiles, etc., which are diversified in function while pursuing practicality and convenience, the piping materials are manufactured based only on the materials and capacity according to the purpose.

Piping work in the construction site is a 3D industry, and it takes a lot of time because the piping work is performed while displaying the connection angle in the field, and the highly skilled assembly technicians and assistants work together. There are a lot of problems with poor piping because of the incorrect arrangement and angle. It is the pipe and piping materials that indicate the reference point of connection angle and the necessary feelings.

The conduit pipes have concave angles so that the connection angle can be recognized no matter where the pipe is cut.

Various pipe connection materials such as elbows and T-type fittings are marked with convex points to make the connection angles recognizable.

90 ° point is also displayed on various piping materials connecting pipes to each other.Plumbing work can be arranged at the correct angle according to the connection angle to reduce the defective rate of field work and improve the working efficiency. Provide pipe and piping materials.

The present invention is to produce a pipe and piping materials marked with the reference angle of connection to make the piping work easier.

Hereinafter, a manufacturing method and characteristics of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a side perspective view of a circular pipe showing a reference angle of a connection angle. In the manufacturing method of various types of pipes, the pipe is marked with an angle reference line because the metal raw material liquefied at high temperature cools and hardens as it exits from the outlet of the pipe forming machine (100). In order to display the connection angle reference line at), it is produced by mass-producing circular pipes by employing only four indicator needles protruding at four 90 ° (101) points and one 45 ° (102) points at the exit of the circular pipe forming machine. .

In the pipe 100 displaying the reference line manufactured by passing through the exit of the circular pipe forming machine provided with the protruding indicator needle, the pipe 100 displaying the angle reference line is manufactured while the line representing the point connecting at a predetermined angle is concave. .

FIG. 2 is a cutaway front view of FIG. 1 in which the 90 ° and 45 points are always displayed when the circular pipe of FIG. 1 is cut in the direction A1-A2. It represents.

3 is a perspective view of the elbow 200 showing the connection angle reference point as a piping material, and FIG. 4 is a perspective view of the T-type fitting 300 showing the connection angle reference point.

Since most of the piping materials of the pipes are manufactured using molds such as casting or die casting injection, it is possible to produce piping materials with desired angles by modifying the molds to display the connection angle reference point.

5 is a perspective view showing an example in which work is carried out using pipes and piping materials marked with connection angle reference points. Since the exact angles are displayed, pipes and pipes with reference angles for connection angle reference points can be easily used in the field. It is a material.

90 ° point is also displayed on various piping materials connecting pipes to each other.Plumbing work can be arranged at the correct angle according to the connection angle to reduce the defective rate of field work and improve the working efficiency. Pipes and piping materials are provided.
