Overview
Precision-Fabricated Shells and Columns for Industrial Projects
NESF fabricates heat exchanger shells and process columns for demanding industrial environments.
We focus on dimensional accuracy, weld integrity, nozzle orientation accuracy, and inspection readiness so your equipment integrates smoothly with piping, instrumentation, and structural supports.
Send your drawing or specification, or share your basic process data and layout. NESF can fabricate to your inspection plan and documentation format.
Scope of Fabrication
- Shells, channels, covers, and heads as per design.
- Small to heavy-duty process columns with platforms and supports when required.
- Nozzles, manways, lifting lugs, supports, and saddles.
- Internals handling support as applicable to the project scope.
Engineering & Compliance
Fabrication is aligned to client specifications and applicable project requirements.
- TEMA expectations for shell-and-tube mechanical construction where applicable to the exchanger shell scope.
- ASME BPVC-aligned pressure equipment practices where specified by the client.
- Project-specific drawings, inspection plans, and acceptance criteria.
QA / Inspection Readiness
- Controlled welding and fit-up practices.
- NDT as specified, including UT or RT where required.
- Pressure and leak tests where applicable.
- Dimensional checks and nozzle orientation verification.
- Inspection records and documentation pack.
Typical Industries
Chemical processing, petroleum-related processing, utilities, specialty manufacturing, and custom industrial projects.
