METHOD TO REMOVE LEAKAGE PROBLEMS IN PIPES PRODUCED FROM PLASTIC-BASE MATERIALS

Abstract: Method to remove leakage problems in pipes produced from plastic-base materials in which choke area is formed by a special method at the same time while muff section is formed and gasket is placed in gasket groove in muff section and outer section is covered with metal and latch or clamp-system is mounted on the male head. In this innovation, it is intended to remove frequently encountered leakage problems by eliminating butt-welding, friction welding, cementing and tight-coupling techniques used in manufacturing irrigation pipes from plastic-base material.

Description: SPECIFICATION METHOD TO REMOVE LEAKAGE PROBLEMS IN PIPES PRODUCED FROM PLASTIC-BASE MATERIALS They are used in gardens, fields, where plastic-base irrigation systems are found. In the presently applied technique, male and female heads are mounted to pipe by the methods of friction-welding, butt-welding, tight coupling or cementing. By eliminating friction-welding, but-welding, tight coupling and cementing, leakages caused by the present techniques will be prevented and the problems encountered in shaping plastic-base material will be removed by the production technology to be selected. Figure 1) Muff section (Female section) : It is formed by a special manufacturing technique, Change in the shape caused by the recovery of memory is prevented by eliminating the existing memory of the plastic material. This is the place where the male section is inserted. Figure 2) Metal covering on gasket groove: Gasket groove found in the muff section is covered by a metal jacket to protect from any damage. Figure 3) Coupling section (with latch or clamp) : It is the place the existing latch or clamp-system is applied. Figure 4) Choke area metal ring : It is the area with a metal ring designed separately for latch or clamp-coupling. Figure 5) Choke area : It is the choke area made on pipe by a special technique for the metal ring not to move out. Figure 6) Gasket : It is a rubber gasket, durable and water-proof in muff section. Figure 7) Pipe section (male) : Pipe section entering into muff section with a bevel-edge. Plastic-base material in granular structure is extruded into tube shape through an extruder. Pipe sample is sent to muff machine to make a muff. Choke area is formed by a special production method at the same time while a muff is made Gasket is placed in the gasket groove in muff section. Outer section is covered with metal. Latch or clamp-coupling is mounted on male head section and made ready to use. Abandoning various welding methods, tight-coupling and cementing intend to prevent leakage through an easy coupling method, to reduce production period and cost and to increase the share in the market. Our company is a manufacturer of plastic pipes and produces such plastic-base pipes according to the structure of soil at the site where pipes to be used. The most convenient system is to use pipes with muff, without welding. Because welded pipes presently used in irrigation require to be revised, for welding is not very well and welding is broken by time under pressure. In addition, this method eliminated controlling of the pipes one by one after welding. Thus, the prices have gone down. Due to above mentioned benefits, our pipes will find a great usage in the industrial field.

Claims: CLAIMS Claim 1 ) A new method in which choke area is formed by a special method at the same time while muff section is formed and gasket is placed in gasket groove in muff section and outer section is covered with metal and latch or clamp-system is mounted on the male head. Claim 2) A method in which choke area is formed at the same time while muff section is formed according to claim 1. Claim 3) A method in which a latch or clamp-coupling system is mounted on the male head, according to claim 1.
