Top five jobs for flange facing machines

Flange-facing machines can be used in a variety of applications for on-site machining. The flexibility that comes with variable feed rates means that the devices can produce a range of surface finishes suitable for many types of flange/gasket connection.

Whether pneumatically or hydraulically driven, flange facing machines can be highly portable and they can operate in very demanding conditions.

Essentially, flange-facing is a process whereby the surface face of flanges and other types of pipe and vessel connectors are machined to restore them to maximum working condition. Where flanges are damaged, seals become prone to leakage and under-performance which requires immediate restoration.

Here are the top five situations where they are utilised across a wide range of industries:

1. The repair of flange faces that have been damaged from impacts with other components during construction or installation. When large plant machinery and other specialised equipment is put together in-situ under demanding conditions, accidental damage can occur.

2. Repairs to corrosion and erosion on flange faces caused by turbulent flow, often high flow rates on larger pipes, or wear and tear on the gaskets which can cause a leaky seal. 

3. Re-facing of hub profiles on the front and rear faces of heat exchangers, oval manways and oval handholds.

4. Weld preps can be carried out using flange facing machines when the right attachments are applied.

5. On-site precision grinding and polishing can also be acheived using flange facing machines if the correct attachments are available.
