Frequently asked questions
Why is scraping poly pipe required before electrofusion?
Scraping removes the oxidised outer layer of poly pipe. If this layer is not removed evenly, contamination can prevent the electrofusion fitting from bonding correctly, increasing the risk of joint failure and leaks.
How much of the pipe should be scraped before electrofusion?
he pipe should be scraped for the full insertion depth of the electrofusion fitting, plus a small margin. This ensures the entire welded area is clean and free from oxidation.
What pipe are these scrapers suitable for
These scrapers are suitable for MDPE and ordinary poly pipe PN12 & PN16. Pipe used in water, gas and other pressure applications, provided the correct size scraper is selected for the pipe diameter.
How do poly pipe scrapers reduce electrofusion failure rates?
By removing the oxide layer evenly and consistently, poly pipe scrapers ensure a clean bonding surface. This dramatically reduces the chance of weak joints, leaks, and costly rework after installation.
