Maintenance and repair

Maintenance and repair

GAB Neumann performs both preventive and corrective maintenance. We maintain, repair, rebuild, or refurbish any piece of graphite or silicon carbide process equipment. We obviously maintain and repair all the pieces of equipment that we have manufactured but also all the pieces of graphite or silicon carbide process equipment originally manufactured by other equipment manufacturers.

Maintenance and repair

Maintenance and repair involves fixing any process equipment that is out of order or broken. It is known as unscheduled repair or corrective maintenance. Unscheduled maintenance usually results from breakdowns or unexpected failures and often causes expensive downtime. Oppositely performing routine actions which keep process equipment in working order is known as scheduled maintenance. It prevents trouble from arising and unscheduled maintenance.

Maintenance and repair by GAB Neumann

GAB Neumann performs both preventive and corrective maintenance. We maintain, repair, rebuild, or refurbish any piece of graphite or silicon carbide process equipment. We obviously maintain and repair all the pieces of equipment that we have manufactured but also all the pieces of graphite or silicon carbide process equipment originally manufactured by other equipment manufacturers.

We fully understand your need to maintain a safe, reliable, and profitable operation.  Our fitters, technicians, and engineers can quickly evaluate the condition of your equipment and address your maintenance needs either at your site, on the phone, or in our workshop. Depending on the emergency of your needs, we would provide either quick fixes or long-term solutions. If sufficient time is available, we can provide a thorough inspection of your equipment and offer our recommendations to refurbish the unit back to original condition. Our approach is to consult with you regarding your options and allow you to determine which degree of refurbishment is appropriate for your circumstances.

Whenever necessary we can reverse-engineer existing pieces of equipment or parts and reproduce them accurately thanks to our versatile and flexible production means. Safety, reliability, and performance on the long-term are our primary considerations when we design and manufacture spare parts for graphite or silicon carbide process equipment.
