Rafter Equipment Corp., a manufacturer of tube and pipe mills, roll forming machines, cutoff machines, and other related tube and pipe mill machinery in Strongsville, Ohio, has shipped a 24-in. weld squeeze box to a North American API pipe producer. The box is part of an upgrade to the customer's existing HFC pipe mill. It is sized for HSLA steel pipe up to 24 in. OD by 0.750 in. wall.
The design includes motorized push-on-center squeeze roll adjustments, linear displacement transducers, load cells, high-capacity tapered roller bearings within the roll tools, and removable head-roll face plate design.
