Underground Solutions | Date: 2012-02-21

An extrudable polyvinyl chloride composition comprising from 80 to 99.9 percent by weight polyvinyl chloride for use in extruding a first part and a second part, wherein a fusion joint between the first extruded part and the second extruded part is formed by: A) composition at least a portion of a first terminal edge of the first extruded part and a first terminal edge of the second extruded part; B) engaging the melted terminal edges; and C) maintaining pressure between the engaged terminal edges to create a fused joint having a strength that is at least 50% of the tensile strength of the extruded part as measured by ASTM D638-2a. The extruded parts can be pipe sections.

Disclosed is a method and apparatus for use in a fusion process for conduit. The method includes the steps of: removably positioning a first terminal edge (18) of a first conduit portion (10) with a first terminal edge (20) of a second conduit portion (12); facing the terminal edges (18, 20) of the first conduit portion (10) and the second conduit portion (12); aligning the terminal edges (18, 20) of the first conduit portion (10) and the second conduit portion (12); melting at least a portion of the terminal edges (18, 20) of the first conduit portion (10) and the second conduit portion (12); engaging the melted terminal edge of the first conduit portion (10) with the melted terminal edge of the second conduit portion (12); maintaining pressure between the engaged terminal edges, thereby creating a fused joint area (22); and removing at least a portion of the resultant external bead (24) extending around the fused joint area (22). A fusion apparatus (14) for employing this method is also disclosed.

Underground Solutions | Date: 2012-09-05

A method for fusing a first conduit to a second conduit. The first conduit and the second conduit each include a linear portion having a linear portion inside diameter, and at least one bell portion with a first end and a second end and having a bell portion inside diameter that increases from the first end to the second end. The method includes: melting at least a portion of each of the second end of the bell portion of the first conduit and the second end of the bell portion of the second conduit; and engaging the melted second end of the bell portion of the first conduit with the melted second end of the bell portion of the second conduit, thereby creating a fused joint area.
