Clamps & hardwareTray columns use a series of horizontal trays to create staged contact between liquid and vapor inside a process column. Reliable operation depends on the correct tray configuration, hydraulic performance, mechanical design, dimensional accuracy and installation.
PunchTech works with plant operators, EPC contractors, engineering consultants and process equipment manufacturers to supply tray systems based on approved process data, drawings, vessel dimensions and project specifications. Our capabilities support:
Tower tray · manufactured to the approved column design
Tray deck, valve elements & fastening
PunchTech manufactures tower trays and tray components for refinery and process-industry columns. Depending on the approved project configuration, the manufacturing scope may include:
Tray type, geometry and performance responsibility are confirmed during technical review.
Depending on the process duty and approved engineering basis, PunchTech can review manufacturing requirements involving the following tray types.
Type 01 · SievePerforated tray decks used for vapor-liquid contact across a wide range of distillation, absorption and stripping services.
Type 02 · ValveTray systems using movable or fixed valve elements to support vapor flow and operating flexibility.
Type 03 · Bubble CapTray arrangements using risers and caps for applications requiring controlled vapor-liquid contact.
Type 04 · CustomProject-specific tray systems manufactured from approved client, EPC, consultant or licensor drawings.
The exact tray configurations designed or manufactured directly by PunchTech are confirmed during the enquiry stage.
PunchTech tray systems can support a broad range of separation and contact duties.
Final tray selection must be based on the approved process conditions and engineering requirements.
PunchTech provides engineering and design support to translate process requirements into practical tray manufacturing and installation deliverables. The agreed scope may include:
Review of available operating conditions, vapor and liquid loads, tray spacing, pressure-drop limitations and operating range for applicable projects.
Assessment of tray configuration, active area, downcomer arrangement, weir details and internal layout.
Review of material availability, perforation, forming, segmentation, fabrication, assembly and inspection requirements.
Consideration of manway dimensions, vessel access, assembly sequence, orientation, support arrangements and site fit-up.
Existing tray columns may have outdated drawings, damaged components, dimensional variations or modified support arrangements. PunchTech can review available information such as:
Where information is incomplete, PunchTech identifies the critical dimensions and inputs required before manufacturing begins.
Explore Replacement & Revamp SupportTray replacement and revamp projects often need to be completed within tightly controlled shutdown windows. PunchTech can support planned shutdown requirements through:
Delivery and site-support commitments are confirmed against the approved project scope and shutdown schedule.
Explore Installation & Shutdown SupportPunchTech's in-house facility connects engineering, production, inspection and dispatch within one coordinated workflow. Manufacturing capabilities include:
Keeping key processes in-house helps maintain control over dimensions, drawing revisions, production sequencing and delivery.
View Manufacturing CapabilitiesTray systems are manufactured according to the material grade specified for the process application and project requirements. Material selection may be influenced by:
Depending on the approved project requirements, quality controls may include the checks listed. Inspection plans, witness points and documentation requirements should be shared during the enquiry stage.
