What Is an Insulation Shop Drawing?
The Technical Bridge from Design to Fabrication and Installation
An insulation shop drawing—also described in some project specifications as an insulation workshop drawing—is a project-specific, dimensioned document that transforms design requirements into information workshop and site teams can use directly.
Unlike a generic typical detail, a shop drawing identifies the actual line, equipment or tank together with its dimensions, insulation build-up, cladding geometry, interfaces, fabrication allowances, component numbers and installation requirements.
ERATHERM coordinates these details around real fabrication methods, material dimensions, access conditions, thermal movement, maintenance needs and the intended installation sequence.
Geometry controlWhere a dimension cannot be verified, the assumption and a clear field verification required note are recorded before fabrication release.
Shop Drawing
- Represents an identified line or equipment item
- Uses project or field-verified geometry
- Includes fabrication and installation dimensions
- Links components to BOM/MTO and revision status
01 · Required Engineering Inputs
From Project Information to Controlled Drawing Data
Drawing accuracy is directly related to the quality and status of the approved engineering inputs.
- Piping isometrics and line lists
- Equipment GA and vendor drawings
- Tank, vessel and nozzle schedules
- Insulation class and thickness schedules
- Operating and design temperatures
- Pipe supports, shoes and anchor locations
- Existing 3D models or point-cloud data
- Site measurements and photographic surveys
- Approved product dimensions and TDS data
- Cladding and fixing requirements
- Numbering and document-control rules
- Client specifications and approved deviations
Input gaps, dimensional conflicts and assumptions are tracked before drawings advance to Approved for Fabrication or Issued for Construction status.

Engineering responsibility boundary
ERATHERM can design insulation support rings, load-bearing inserts, cladding connections and thermal-break details. Final structural adequacy of pipe shoes, anchors, guides, vessel attachments and welded load-bearing supports must be verified by the responsible piping-stress, structural or pressure-equipment discipline.
Attachments welded to pressure equipment also require approval by the vessel manufacturer or owner before fabrication.

Frequently Asked Questions
Insulation Shop Drawing Preparation
What is included in an industrial insulation shop drawing?
A shop drawing identifies project-specific dimensions, insulation layers, cladding geometry, joints, supports, penetrations, fabrication allowances, component numbers and installation requirements.
What is the difference between a typical detail and a shop drawing?
A typical detail describes a general construction principle. A shop drawing applies that principle to an identified component using project-specific geometry, dimensions and fabrication information.
Can insulation shop drawings be prepared from piping isometrics?
Yes. Piping isometrics can be used with line lists, insulation class schedules, support information and verified dimensions. Missing data are recorded as assumptions or field-verification requirements.
Can shop drawings be prepared for existing plants?
Yes. Brownfield drawings can be developed using available records, site measurements, point-cloud data, photographic surveys and verified equipment dimensions.
How are cladding dimensions and overlaps determined?
They are determined from the insulated outside diameter, component geometry, cladding material, fabrication method, joint orientation, thermal movement, drainage requirements and project specification.
Can ERATHERM prepare tank and vessel panel maps?
Yes. Course layouts, panel dimensions, joint positions, support-ring interfaces, roof details and component-numbering plans can be prepared for tanks and process vessels.
Can shop drawings be linked to BOM and MTO?
Yes. Drawing numbers, component tags, materials, quantities, purchasing units, packages, work-fronts and revision status can be coordinated within a drawing-linked BOM and MTO structure.
Does ERATHERM design pipe supports?
ERATHERM can design insulation support rings, load-bearing insulation inserts, cladding interfaces and thermal-break details. Final structural verification of pipe shoes, anchors, guides and welded supports remains with the responsible project discipline.
Are shop drawings issued directly for fabrication?
Drawings are issued for fabrication only after the required inputs, dimensions, material system and review status have been confirmed under the agreed document-control procedure.
Can ERATHERM issue as-built insulation drawings?
Yes. Approved field changes and final installed conditions can be incorporated into revised drawings, registers and BOM/MTO records to create an as-built documentation package.
