Lower-investment equipment matching and deep remanufacturing services.

We match available used tube mills and coil processing lines to buyer requirements. Deep remanufacturing can include full dismantling, inspection, replacement of critical worn parts, electrical upgrades, accuracy calibration, testing, installation and commissioning support.
COMPLETE PRODUCT INFORMATION
In response to market demand, Fengqi provides used welded-tube equipment matching and deep remanufacturing through two service routes.
Used equipment matching: using more than 20 years of industry experience and used-equipment resources, Fengqi matches suitable equipment to customer requirements so machinery can be reallocated and reused effectively.
Deep remanufacturing: the complete machine is dismantled and inspected, critical worn components are replaced, the electrical system is upgraded, complete-machine accuracy is calibrated and strict final inspection is performed to support stable production.
Installation guidance, commissioning support and long-term spare-parts supply are available.
The objective is new-machine quality at a used-equipment investment level.
Industry resources and equipment matching based on the buyer’s production requirements.
