Heat Exchanger Design & Drawing Services

Technical drafting and documentation support for shell-and-tube exchangers, air-cooled equipment and associated structural interfaces. We help project teams translate approved design inputs into coordinated general arrangements, component details and fabrication drawing packages.

Service scope

Heat exchanger drawing and coordination support

Structural Drafting India supports engineering consultants, equipment manufacturers and fabrication teams with documentation developed from client specifications, approved calculations, equipment data and applicable project standards. Scope, software and deliverables are agreed for each assignment.

Shell-and-tube exchangers

General arrangements, shells, heads, tube sheets, baffles, channel arrangements, flanges and maintenance clearances based on approved design data.

Air-cooled equipment

Layout coordination for bundles, fan and drive interfaces, header locations, supporting steel and accessible maintenance zones.

Nozzles and piping interfaces

Nozzle orientation, connection schedules, elevations, face-to-face references and coordination with piping layouts.

Fabrication details

Dimensioned components, weld and material notes, item references and drawing revisions in line with approved requirements.

Supports and access steel

Saddles, support locations, base interfaces, platforms, ladders and handrails coordinated with the equipment footprint.

3D models and drawing conversion

2D CAD documentation and model-based coordination from supplied reference material, where included in the project scope.

Technical inputs

What we need to begin

Accurate drawing preparation starts with an agreed set of technical inputs and clear responsibility for engineering decisions.

  • Equipment data sheets, service conditions and equipment type
  • Approved thermal and mechanical design calculations, where applicable
  • Material specifications, design code and client drafting standards
  • GA sketches, nozzle schedules and piping interface dimensions
  • Support reactions, foundation interface and plant layout constraints
  • Reference models, markups, revision register and output formats

Documentation outputs

Typical deliverables

  • Equipment general arrangement drawings and sections
  • Shell, head, tube sheet, baffle and nozzle details
  • Nozzle orientation and connection reference drawings
  • Support, saddle, base and mounting interface details
  • Weld references, drawing notes and schedules as specified
  • PDF and editable CAD files; model files if agreed
Engineering responsibility: Pressure boundary design, thermal sizing, code compliance, pressure calculations, safety checks and final approvals must be performed or verified by appropriately qualified, authorized professionals. Drafting output alone does not establish equipment fitness for service.

Coordination process

From approved inputs to controlled drawings

Scope and inputs

Confirm equipment type, reference documents, drawing register and responsibilities.

Prepare drawings

Develop GA, sections and component details from approved source data.

Check interfaces

Review nozzles, supports, clearances, material references and markups.

Revise and issue

Incorporate authorized comments and deliver the agreed files and revision record.

Common questions

Heat exchanger detailing FAQs

Do you prepare shell-and-tube heat exchanger drawings?

Drawing support may include general arrangements and component details for shell-and-tube units, based on the approved scope and reference engineering information.

Can the drawings include nozzle and support interfaces?

Yes. Nozzle positioning, saddle or base locations, maintenance space and supporting steel interfaces can be coordinated when the required dimensions and loading information are provided.

Do you perform ASME or TEMA certification?

Certification is not implied by drafting. Code selection, thermal and mechanical design calculations, inspection requirements and statutory approvals must be confirmed through the project's designated qualified professionals.

Which files can be supplied?

PDF and editable CAD deliverables can be included. Three-dimensional model files, component schedules and client-specific templates depend on the agreed project requirements.
