Custom couplers designed, manufactured and installed for Saskatchewan potash mine
Overview: The potash mine required a flow meter installed on a brine pipeline for their potash mine.
Challenge: Maintenance staff could not completely stop the flow of brine through the pipe, a 32” metric HDPE DR17 brine pipeline, which eliminated butt fusion or electrofusion as possible options for this difficult process.
Robar solution: To meet the customer’s need, manufactured two mechanically restrained couplers c/w with stainless steel inserts (7946RFCAH 30D 31.59-.25×14 HDPE) and worked directly with the customer’s staff to field-measure the pipe, before determining the insert would need to be slightly enlarged to fit appropriately.
Results: With the flexibility of the Robar product, the insert was cut, expanded and welded in the field, avoiding a costly delay for the customer.
