On Site Machining
Manufacturer of portable machining equipment
Qualified technicians to perform your IN SITU machining works
Some tubular components, flanges, valves, high pressure valves, sealing valves, valves seats, conical seats and others require preventive maintenance but also sometimes curative maintenance.
Some of those components are light, easy to disassemble and consequently easy to transport.
Some maintenance or repair works can be easily scheduled.
But...
Some maintenance or repair works can suppose that some parts or components will have to be put on a workshop fixed machine which will be mobilized for those works. This will mean that in most cases, the following actions will have to be done:
- First, the part(s) will have to be disassembled.
- They will have to be packed for the shipment.
- A specific shipment will have to be organized.
- If the case arises, the parts will be stored awaiting the availibity of a lathe, or of a milling machine or other
appriopriate workshop fixed machine.
- Several persons, including material handlers, will also be mobilized.
- A return shipment will have to be organized.
- Strict and complicated handlings will have to be performed in order to avoid damaging the parts during their
shipment and during their re-assembly on site.
- Any other actions which will be necessary (particularly, if the components that need a re-machining,
a maintenance or a repair, have been subject to hazardous environment - ionizing radiation for example...).
