text: Advantages of electrofusion welding:
  * Simple process capable of producing consistent joints
  * Process is entirely contained, reducing the risk of joint contamination
  * Process allows repair without the need to remove pipes 
  Disadvantages of electrofusion welding:
  * A special sleeve is required, so it is more expensive than other pipe joining methods such as hot plate joining
  * Implanted coils make recycling of parts more difficult
