Strongsville, Ohio, USA, October 11, 2016 – Rafter Equipment Corporation has shipped an RT-8000 weld squeeze box head roll assembly retrofit to a major South American producer of direct-welded HSS tubular products. The customer approached the company to help solve the rigidity issues with the head roll assembly on their existing Chinese-made 5-roll HFI/HFC weld squeeze box. The existing unit was incapable of welding the heavier wall thicknesses. It was determined that the existing side and lower roll assembly was sufficient, so Rafter proposed a head roll retrofit solution.

The SOU is adjusted electrically and can be controlled remotely from a downstream position if desired.
