‘EL’ Type
The ‘EL’ type tube expander is similar in design to the basic ‘E’ type tooling but throughout the range the fixed parallel rolling length is 11/2” (38.10mm). The rollers have a generous nose radius on the front end.
Description
The ‘EL’ type tube expander is similar in design to the basic ‘E’ type tooling but throughout the range the fixed parallel rolling length is 11/2” (38.10mm). The rollers have a generous nose radius on the front end.
When tooling of this pattern is required for tube sizes beyond 3” o/d or to suit thicker boiler drums, longer reach conditions and for cramped access in headers and super heaters for example please select your requirements from “A” series expanders and appropriate mandrels to suit.
