Graphite spare parts

GAB Neumann’s manufactures spare parts for graphite and silicon carbide process equipment. We keep some essential spare parts on inventory and manage to produce the others rapidly. We manufacture the spare parts for our own equipment but also for pieces of equipment originally produced by other graphite or silicon carbide original process equipment manufacturers.

Spare parts

Spare parts are used for the repair or replacement of failed units. In the chemical, fine chemical, and pharmaceutical industries spare parts management is a very important aspect of supply chain management as it might affect the companies’ ability to produce or at least to produce at full capacity.

Corrosion resistant chemical Process equipment are usually considered as critical pieces of equipment as they are often custom made. These piece of equipment, although acknowledged to have a long life or a small chance of failure, would cause a long shutdown of the production unit because it would take a long time to get a replacement for them.

GAB Neumann’s spare parts

Providing graphite and silicon carbide process equipment spare parts to chemical, fine chemical and pharmaceutical companies worldwide is an important aspect of GAB Neumann’s mission as we implement all the possible measures to keep our customers operating with as little disruption as possible. We keep some essential spare parts on inventory and manage to produce the others rapidly.

GAB Neumann’s manufactures spare parts for graphite and silicon carbide process equipment. We manufacture the spare parts for our own equipment but also for pieces of equipment originally produced by other graphite or silicon carbide original process equipment manufacturers. Whenever necessary we can reverse-engineering 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.

The manufactured spare parts can be fitted with optional features such as carbon fiber reinforcement if required. Whenever necessary the spare parts might be reengineered, improved, or adapted to better fit with the customer’s new requirements.

Our graphite spare parts are machined after phenolic resin impregnation thus guarantying a surface totally free of resin and ensuring therefore the highest possible heat transfer performance.
