Description

THE IMPROVEMENT OF CONNECTION \BUTTFUSlON\ QUALITY

WITH CONNECTION SUPPORTING COMPONENTS

Field of the Invention

This invention is related to an improvement of connection qualityof the end of the pipe-mixture [btittfusiori]. In particular, this invention is related to an improvement of connection quality of the end of the pipe-mixture [buttfusion] with supporting components on the connection of the ends of the plastic pipe, by increasing the thickness of the pipe wall at the end of the plastic pipe through the assembly of new components that fit the invention, so that the strength of the connection can be accurately assured and the strength of theconnection at the end of the pipe can be guaranteed.

Background of the Invention

In the plastic industry, especially in the plastic pipe industry, one of the method of connecting the plastic pipe that is most frequently used is the method of connecting the end of the pipe-mixture [biittfusion]. The method of connecting the end of the pipe- mixture [buttfusion], can connect the two ends of plastic pipe compound by heating both ends using the heating plate. The common steps that are usually done in the method of connecting the end of the pipe-mixture [buttfusion] are as follows:

1) providing two pieces of plastic pipes with the same compound that will be connected;

2) flattening and smoothing both ends of the plastic pipes that will be connected;

3) sticking both ends of the plastic pipes that will be connected to heating plate;

4) heating both ends of the plastic pipes that will be connected by heating the heating plate; 5) both ends of the plastic pipesthat have been heated are separated from the heating plate and joined in a short time with a certain pressure; 6) leaving the connection to cool so that it fused compoundly; The connection of the ends of the plastic pipes with the method of connecting the end of the pipe-mixture [buttfusion] usually left a little bulge at the connection both on the outside and the inside of the plastic pipe as a result of the application of pressure while the process of connection is ongoing. The excess of this bulge can be easily cleaned away.

The technology method of connecting the end of the pipe-mixture [buttfusion] has been invented and industrially applied in a long time. Some of the improvement on the technology of the heating plate has also been done such as covering the heating plate teflon to prevent the sticking of plastic pipe material on the plate, etc. However, the technology of connecting the end of the pipe-mixture [buttfusion], especially in plastic pipe connection technology, has several weaknesses. One of the weakness is found in the strength of the connection result of the method of connecting the end of the pipe-mixture [buttfusion], where is the strength of connection relies on the thickness of the material or pipe that will be connected.

At this point, if the strength of the connection want to be improved, then the thickness of the material or the pipe must be increased in order to thicken the connection surface for connecting the end of the pipe-mixture [buttfusion]. Therefore, in connecting the end of the pipe-mixture [buttfusion], it generally requires pipes with high thickness in order to ensure the result of connection to be strong and leak-proof, especially when the connection have to be bent. This causes that the plastic pipe that is going to be connected with buttfusion method must be produced with high thickness.This is very inefficient, causing excessive use ofraw materials, high prices, and the heavy weight of plastic pipe leads to high transportation costs. If that plastic pipe will be used as floating device as usually used in circular floating fish cage, the heavy weight of the plastic pipe will severely reduce buoyancy. In relation with the existence of several obstacles as mentioned above, the inventor proposed a new invention that relates to the method of connecting the ends of the pipe by thickening the end of the plastic pipe that will be connected without having to thicken the whole of pipe, where the thickness addition is done through the addition of components such as the outer ring, inner ring and the leak-proof partition, which is applied by the inventor as a new invention, so that the process of connecting the end of the pipe-mixture [buttfusion] can produce a stronger connection without having to use excessive raw materials. Therefore, the pipe does not need to be produced too thickly, only needs to be produced with enough thickness for the particular needs, resulting in improvement of raw materials efficiency, price reduction, and ease of transportation.

There are three kinds of methods that are proposedto increase the thickness of the ends of pipes for buttfusion process. The first method is for the purpose of fluid material piping that is commonly used for drinking water pipes, gas pipes, and others. The thickness addition of the end of pipe is done outside of the pipe so that there is no obstacle to the flow of thefluid material inside the pipe.

The second method is also for the purpose of fluid material piping, but applied when thickness addition of the end of the pipe is not possible to be added on the outside of the pipe, thus the thickness addition of the end of the pipe is added on the inside of pipe. Additional tools can be attached to this (eg: flow meters, pressure gauges, etc).

The third method is for the purpose of manufacturing a floating device, where the thickness addition of the end of the pipeis in the shape of a partition, to prevent water from entering the pipe.

Seeing broad application in this invention, the method that is proposed by the inventor in this invention can be used in many industries ranging from piping industry to floating fish cage industry, and greatly reduces cost. Therefore, the inventor hopes that this new invention relating to the connection methods of the ends of the plastic pipes along with the engineering technologies on components that support this invention will be the best solution to the obstacles of plastic pipe connection that are discussed above.
