ASTM Electrofusion Coupler

Pressure rating:

Category: ASTM PE Piping System

Smart Joint produce ASTM electrofusion couplers up to 36" in SDR11(200 PSI working pressure at 73.4° F) , SDR17(125 PSI working pressure at 73.4° F), with both IPS size and DIPS sizes.  SDR9(255 PSI working pressure at 73.4° F)& SDR(335 PSI working pressure at 73.4° F) can be supplied per request.

Depending on the sizes, smart joint electrofusion couplers are divided as followed table:
One fusion zone, two adaptors.
Two fusion zone, four adaptors.
One-step fusion process, one white fusion barcode.
Two-steps fusion process, one yellow pre-heat barcode, on white fusion barcode.

Electrofusion Coupler Size Fusion Zone Fusion Process

IPS 1"-8",DIPS4"-8"  One Fusion Zone One-step Fusion Process

IPS 10"-16",DIPS 10"-14" One Fusion Zone Two-steps Fusion Process

IPS18"-36",DIPS16"-24" Two Fusion Zones Two-steps Fusion Process in Each Fusion Zone

All electrofusion installation shall be performed by a trained and certified technician.

For the large size electrofusion couplers, if the pipe has severe ovality problems, re-round process will be required to guarantee the reliable joint.

If the large pipe OD is not within the standard tolerrance, pls contact with smart joint in advance, we can machine the coupler per the requirement.
