What this service covers

Flange resurfacing and flange facing services

Fairtex performs onsite flange resurfacing and flange facing for raised face (RF), flat face (FF), and ring joint (RTJ) flanges using portable flange facing equipment. Our machining services restore gasket seating surfaces damaged by corrosion, leakage, pressure wear, or mechanical degradation. This helps maintain flange sealing integrity and reduces the risk of leaks within piping systems.

Pipe cold cutting and beveling services

We provide cold cutting and beveling services for thin-wall, thick-wall, and heavy-wall piping systems using lightweight split-frame pipe cutting machines. Our equipment supports precise weld preparation, valve fitting preparation, pipe severing, and edge preparation activities while minimizing heat generation and operational disruption during maintenance or construction work.

Portable onsite machining support

Fairtex supports field machining requirements with portable equipment designed for rapid mobilization and operation in restricted industrial workspaces. Our capabilities include pipe cutting, beveling, flange machining, weld preparation, and maintenance support for process piping, vessel systems, and industrial utility infrastructure.
