2-Ethylhexanol process line — reported weld leak
Field Reality
An insulated Ø100 mm process line carrying 2-ethylhexanol was leaking at a weld. The line normally ran at about 170 °C with occasional peaks to 200 °C. The insulation had to be opened before anyone could see the weld at all, so the first Field task was simply getting to the condition. For this Case the written procedure required the line to be shut down and cooled before hands-on ISB construction.
Key verified Field facts
- Medium
- 2-Ethylhexanol (2EH / isooctanol) operator-reported service
- Pressure
- 0.4 MPa operator-reported
- Temperature
- 170 °C operating, with occasional peaks to 200 °C operator-reported
- Asset
- Insulated Ø100 mm process line operator-reported
- Geometry
- Weld on an insulated process line, accessible only after the insulation was opened observed in the Field record
- Field condition
- Reported leak at a weld, hidden beneath insulation until the insulation was opened observed in the Field record
- Dominant hazard / constraint
- Hot organic process fluid at a concealed weld; the written procedure required shutdown and cooling before hands-on construction operator-reported procedure for this Case
Resulting ISB
An ISB was constructed around the weld region and finished with an external protection layer. The source record documents the construction sequence only.
Case boundary
This Case records one unique Field Reality. It is not a construction instruction and not a template. A Solution developed for one Field must not be copied into another Field without new DendroSeal Understanding.
Field Link
The connection layer between the Field and DendroSeal. Reality can arrive before anything else is settled.
