Static Equipment Design
Structural Engineering Services specialises in designing floating head, fixed tubesheet, U-tube, stacked and kettle exchangers per TEMA.
Quick answer
Heat Exchanger Mechanical Design is the process of designing floating head, fixed tubesheet, U-tube, stacked and kettle exchangers per TEMA. Structural Engineering Services delivers it worldwide on licensed PV-Elite, Codeware COMPRESS, Autodesk Inventor to ASME Sec VIII Div 1/2, EN 13445, PD 5500 and client specifications.

Why us
Whether you are a fabricator racing a shop schedule, an EPC contractor managing multiple disciplines or an owner needing an independent check, our heat exchanger mechanical design team works as an extension of yours. Every deliverable passes a two-stage check by senior engineers before it leaves our office.
Deliverables
The standard static equipment design package. Anything outside it is priced as a named add-on, never assumed.
Mechanical design calculations
General arrangement drawing
Fabrication & detail drawings
Nozzle load & local stress checks
Material & weight summary
Lifting & foundation loads
Compliance
Every heat exchanger mechanical design package is engineered to the governing codes below and to any client or authority specification you issue with the enquiry.

Who we work with
The scope looks similar on paper. What each buyer actually needs from it does not — so the engagement is shaped around it.
Shop loaded, schedule fixed, no spare detailing capacity in house.
What you get
A calculation set that passes the inspection authority first time, with drawings dimensioned the way your shop actually rolls, welds and tests.
Multi-discipline scope, moving client revisions, hard contractual dates.
What you get
Mechanical design capacity on demand for every vessel, exchanger and tank in the package, consistently documented across the whole job.
Work won beyond current capacity, delivered under your own stamp.
What you get
Code calculations and GA drawings produced under your review, with assumptions documented clearly enough to defend to a notified body.
Plant modifications, life extension and independent verification.
What you get
Equipment designed for the service it will actually see — with re-rating and fitness-for-service options kept open for later life extension.
How we deliver
The same engagement runs every heat exchanger mechanical design project, whether it is a single package or a multi-year frame agreement — so you always know what happens next and who owns it.
Send what you already have — process datasheet, design pressure and temperature, corrosion allowance, materials of construction, nozzle schedule and the applicable design code and jurisdiction. Incomplete inputs are fine; we list the gaps rather than guess at them.
A senior engineer reviews the package and returns a priced proposal with scope, assumptions, exclusions and a milestone plan for your heat exchanger mechanical design. No obligation, no placeholder pricing.
Shell, heads, nozzles, reinforcement, saddles or skirt and lifting attachments are sized in PV-Elite or COMPRESS to the governing code, with MAWP, MDMT, hydrotest and wind/seismic cases all resolved before any drawing is started.
Nothing leaves our office on one pair of eyes. An independent checker verifies the technical content, then a senior engineer approves it against ASME Sec VIII Div 1/2 / EN 13445 and your project specification.
Issue includes the stamped-ready calculation set, GA drawing, fabrication and nozzle detail drawings, weld-detail sheets, material and weight summary, and the lifting and foundation loads your structural team needs. Comments are closed within two revision cycles, and RFIs raised during fabrication or construction are answered inside 48 hours.
Scope matrix
No vague scopes and no surprise variations. This is what sits inside the base price, what you can bolt on, and what we need from you to start.
Swipe the table sideways to see every column
| Work package | Included in base scope | Optional add-on | What we need from you |
|---|---|---|---|
| Mechanical design | Shell, head, nozzle, reinforcement, support and MAWP/MDMT calculations | Design-by-analysis (Div 2 Part 5) where design-by-rule is uneconomical | Process datasheet, design conditions, corrosion allowance and materials |
| Load cases | Wind, seismic, hydrotest, erection and operating load cases | Transport and lifting analysis, fatigue and cyclic service evaluation | Site wind/seismic data, orientation and installed/erected condition |
| Nozzle & local loads | WRC 107/297 local stress checks at nozzles and attachments | Local FEA where WRC geometry limits are exceeded | Piping nozzle loads or an allowable-load table to design against |
| Drawings | GA drawing, fabrication details, nozzle schedule and weld details | Internals, trays, demisters, insulation and fireproofing detailing | Vendor internals data, client drawing template and title block |
| Documentation | Material and weight summary, lifting and foundation load data | Full manufacturer data report pack and authority/notified-body liaison | Jurisdiction, inspection authority and certification requirements |
| Fabrication support | RFI response and clarification during fabrication | Weld procedure review, NDE plan input and as-built drawing update | Shop queries consolidated through a single point of contact |

Engagement & pricing
Pick the commercial model that matches how your heat exchanger mechanical design work arrives — one-off package, measurable units, or continuous capacity.
one price, whole scope
Best for
Defined heat exchanger mechanical design packages where the inputs are frozen and you need budget certainty before you commit.
Scope, assumptions and exclusions written into the proposal, so variations are visible rather than invoiced quietly.
per vessel / exchanger / tank
Best for
Fabricators and OEMs quoting discrete equipment items with a defined datasheet.
Priced per item with repeat-of-type items at a reduced rate.
per fabrication drawing
Best for
Drawing-only scopes where the mechanical design already exists and is approved.
Suits re-rating, re-drafting and vendor-drawing completion work.
per engineer month
Best for
Continuous workload, frame agreements and clients who want a named engineer who learns their standards and stays on the account.
Your engineer works on licensed PV-Elite inside your workflow, reporting to your lead as an extension of your team.
Not sure which model suits your heat exchanger mechanical design scope? Send the drawings — the proposal prices two options side by side.
Get a free quoteQuality assurance
Every heat exchanger mechanical design deliverable is checked by an engineer who did not produce it, then approved by a senior engineer who signs it by name.
Checked by an engineer who did not produce the work
The checker rebuilds the critical numbers rather than reading along with them, marking up every sheet of the heat exchanger mechanical design package against the inputs.
Approved by name against ASME Sec VIII Div 1/2, EN 13445, PD 5500
The approving engineer looks past compliance at whether the solution is buildable, economical and right for how the asset will actually be used.
Only then is the package released — with the checker and approver recorded against the revision.
