Basic Concepts of Electrofusion Sleeve Insertion Depth
The insertion depth of an electrofusion sleeve refers to the length of the pipe inserted into the sleeve, directly affecting the sealing and strength of the connection. For 90mm sleeves, the insertion depth is typically between 40-50mm. This value is set based on material properties and the requirements of the electrofusion process, ensuring uniform heat distribution during welding and avoiding localized overheating or insufficient welding.
Impact of Insertion Depth on Connection Quality
Sealing: Insufficient depth may lead to insufficient contact at the weld surface, resulting in micro-leakage.
Tensile Strength: Appropriately increasing the depth can improve the mechanical strength of the connection.
Stress Distribution: A reasonable depth ensures more even stress distribution on the pipe, reducing stress concentration.
Precautions in Practical Applications
The pipe end face must be flat and clean to avoid impurities affecting the welding effect.
Keep the insertion vertical to prevent skewing that could lead to uneven insertion depth.
When the ambient temperature is below 5℃, it is recommended to appropriately increase the preheating time.
Different pipe materials may require adjustments to the insertion depth parameters.
