Electro-fusion joining system for thermoplastic piping systems |
摘要 |
An electro-fusion drainage system coupling has a tubular body with outer and inner substantially parallel surfaces. The inner surface defines a passageway from end to end. A resistive heating element is disposed in the passageway. The predetermined distance represents a desired insertion distance of the pipe into the coupling body passageway. The electro-fusion coupling may further include a stop positioned in the passageway to contact the end of the thermoplastic pipe inserted into the passageway. Other implementations include an electro-fusion coupling with a fitting integrally formed on a second end and a thermoplastic piping system presented in a kit. Methods of the invention are also described.
