Overview
Heat exchangers demand high‑precision plates and features for dependable thermal and fluid performance. We coordinate the complete workflow — quoting, material procurement, machining, inspection, and logistics — so your tube sheets, baffles, and flanges meet dimensional and sealing requirements.
Routing is selected to best fit your size, material, tolerance, and schedule requirements.
Quick Specs
| Component | Best For | Throughput | Notes |
|---|---|---|---|
| Tube Sheets | High hole‑count accuracy & sealing faces | Medium | Bolt circles, tube pitch & ligament control; counterbores/chamfers as required |
| Baffles / Support Plates | Flow control & bundle support | High | Pattern drilling; deburr/edge‑break for tube protection |
| Nozzles & Flanges | Weld‑prep & bolt‑up alignment | Medium | Facing, beveling, gasket‑surface prep (e.g., RTJ) |
| Shell / Heads | Machined features for assembly | Medium | Manways, ports, and machined pads by review |
Capabilities
- High‑density drilling for tube sheets with precise pitch & ligament spacing
- Counterboring, chamfering, and back‑deburring to protect tube ends
- Layout machining of bolt circles, keyways, and slots
- Facing, beveling, and weld‑prep per WPS/PQR requirements
- Surface grinding or fly‑cutting of sealing faces for gasket performance
- Large baffle/support plate profiling with burr control
- Nozzle & flange machining (ID/OD, bolt patterns, gasket prep by review)
- Material procurement with traceability (MTRs, heat numbers)
- Dimensional inspection: CMM/optical verification and bolt‑circle validation

Heat Exchanger Machining FAQs
What information speeds up a tube sheet or baffle quote?
Upload your PDF + STEP (if available), material grade, thickness, hole Ø & pitch, quantities, finish/flatness targets, any TEMA/ASME callouts, and your required date. Photos with scale help for replacements.
Can you align to TEMA/ASME practices and provide documentation?
Yes. We follow your print/specs and can supply MTRs, CoC, FAIR/FAI, CMM bolt‑circle reports, and PMI/hardness testing by request.
How is hole quality managed for tube insertion and sealing?
We plan tooling and breakthrough control, add back‑deburr/chamfer as specified, and verify critical dimensions to protect tubes and gaskets.
Do you handle material sourcing and protective finishes?
We can procure CS/SS/Duplex/CuNi/Ti with full traceability and coordinate passivation or protective coatings when required.
Can you support outage windows or rush jobs?
Often. Note your window or need‑by date on the RFQ and we’ll propose the fastest viable routing and delivery plan.
