PunchTech supports the replacement, modification and revamp of mass transfer equipment and column internals for refineries, petrochemical plants, fertilizer facilities and process industries.
Using available drawings, field measurements, photographs, samples and operating information, our team helps define a practical engineering, manufacturing and installation scope for existing equipment.
Existing columns and process vessels often present challenges that are not found in new-build projects. Drawings may be incomplete or outdated. Equipment dimensions may differ from original records. Access may be restricted, and replacement work may need to be completed within a planned shutdown window.
PunchTech reviews the available technical and site information to develop replacement components that are practical to manufacture, transport, assemble and install.
Our support can begin with a complete technical package or limited information from the existing equipment.
Replacement of worn, damaged, corroded or obsolete internals based on approved drawings, existing equipment information or verified measurements.
Manufacturing support for modifications, upgrades and capacity-improvement projects based on an approved engineering or process design.
Engineering and manufacturing coordination for replacement components required within planned maintenance or refinery shutdown schedules.
Review of vessel access, component segmentation, support arrangements, assembly sequence and installation constraints.
Assessment of available field dimensions, photographs, inspection records, existing drawings and equipment details.
Fit-up assistance, installation supervision and replacement support where included in the agreed project scope.
The final scope is defined according to the existing arrangement, approved design basis, material requirements and site conditions.
Replacement projects do not always begin with a complete or current drawing package. PunchTech can review combinations of:
Where information is missing, our team identifies the additional measurements, drawings or technical clarifications required before manufacturing release.
For revamp and capacity-improvement projects, PunchTech can translate the approved process or hydraulic design into a practical manufacturing and installation scope. Support may include:
Process performance guarantees, hydraulic guarantees and specialized process studies should be defined separately within the agreed engineering scope.
A replacement component must fit the existing vessel — not only the drawing. PunchTech reviews practical site constraints such as:
Large internals can be manufactured in identified segments for transportation through vessel manways and assembly inside the column.
Shutdown projects require early technical clarification, controlled manufacturing and close coordination between engineering, production, inspection and site teams. PunchTech can support pre-agreed shutdown requirements through:
Delivery schedules and site-support commitments are confirmed according to the final technical scope, project location and production plan.
Replacement components are inspected against the approved drawings, dimensions and project quality requirements. Depending on scope, controls may include:
Any critical field dimensions should be verified before manufacturing release.
Where available, please provide the information below. The enquiry can still be reviewed when some information is unavailable.
PunchTech will identify what is required to proceed responsibly.
Focused capabilities across tower trays, packing systems, column internals and mist elimination equipment.
Design details, manufacturability, inspection and installation considerations managed within one workflow.
Requirements can be reviewed from drawings, measurements, photographs, field information or physical samples.
Integrated cutting, punching, forming, fabrication, assembly and inspection capabilities.
Structured planning for time-sensitive replacement and maintenance requirements.
Components designed and segmented with vessel access, assembly and fit-up in mind.
Share your existing drawings, inspection findings, field dimensions or equipment photographs. PunchTech will review the available information, identify the technical inputs required and define a practical engineering and manufacturing scope.
