Abstract

PURPOSE:To enable the connection of polyethylane pipes, by a method wherein the space is provided between the end surface of polyethylane pipes at the condition a stainless pipe is inserted in the inner surface, and the exposed part of the stainless pipe is heated, and confronting end surfaces of polyethylane pipes are contact bonded. CONSTITUTION:The stainless pipe 2 having nearly the same outer diameter with the inner diameter of polyethylane pipes 1, 1' is inserted to the polyethylane pipes 1, 1', and the prescribed space is provided between the end surfaces of the polyethylane pipes 1, 1'. Next, after the exposed part of the stainless pipe 2 is heated to the prescribed temperature, the confronting end surfaces of the polyethylane pipes 1, 1' are contact bonded mutually at once. Hereby, it becomes possible to surly connect the polyethylane pipes without the center discrepancy, and abnormal protruding due to the contact bonding will not generate in the inside surface of pipes.

、あるいは金属継手の使用によってなされていた。(Prior Art) The conventional method for connecting polyethylene pipes is to melt the ends of the polyethylene pipes in a heated bath using a machine or manually to form a bead, and then press and fuse the bead. This was done by using metal fittings.

た。(Problems to be Solved by the Invention) However, the fusing method has problems in that the formation of a bead portion causes a bead, that is, a protrusion, on the inner surface of the polyethylene pipe, resulting in a change in the flow rate at the connecting portion of the polyethylene pipe, and that manual fusing is required. 9. In this case, there is a problem that the core misalignment (91 flat) occurs in the polyethylene pipe during the formation and crimping of the bead part. Also, the use of metal joints has had Mt- while increasing component costs.

Connecting the pipes with a predetermined distance between their end faces,
This is a connection method in which the exposed portion of the stainless steel tube is then heated, and the opposing end surfaces of the polyethylene tube are crimped and fused.

A is chamfered to reduce fluid resistance. Then, the exposed part of the stainless steel pipe 2, that is, the polyethylene pipe 1
．． The portion located between the end faces of polyethylene pipe 1.11 is heated to about 200°C, and the end faces of polyethylene pipe 1.11 are immediately crimped as shown in FIG.

When the end faces are crimped, the crimped portions are melted and fused to establish a connection. Since the vicinity of the end of the polyethylene pipe 1.11 is compressed by the crimping, the end swells outward, and as a result, the fused area becomes large and fusion is reliably performed. Further, at the end of the stainless steel tube 2, the inner surface of the polyethylene tube 1.11 is slightly raised by the pressure bonding, thereby fixing the stainless steel tube.

Tubes also have the advantage of being less expensive than traditional metal fittings.
