What Information Is Needed to Quote Custom Turbine Repair Parts?
What Information Is Needed to Quote Custom Turbine Repair Parts?
To quote custom turbine repair parts accurately, the supplier usually needs 2D drawings, 3D CAD files, old samples or 3D scan data, material requirements, quantity, process requirements, inspection standards, documentation needs, and delivery targets. The more complete the RFQ information is, the more accurately NewayAeroTech can evaluate the manufacturing route, cost, lead time, quality risks, and finished-part delivery scope.
For custom gas turbine repair parts, the quotation should not be based only on part size and quantity. Gas turbine replacement parts may require superalloy casting, CNC machining, EDM, deep hole drilling, heat treatment, coating preparation, NDT, dimensional inspection, material reports, and traceable delivery documentation.
1. Direct Answer: What Information Is Needed for a Custom Turbine Repair Parts Quote?
A custom turbine repair parts quote usually requires drawings, 3D CAD files, old samples, 3D scan data, CMM data, material grade, heat treatment condition, coating requirement, quantity, manufacturing scope, inspection standard, documentation requirement, and target delivery schedule. If the part is reverse engineered, the turbine model, part location, photos, damage areas, and functional surfaces should also be provided.
RFQ Information | Recommended Input | Why It Matters |
|---|---|---|

2. What Drawing and CAD Files Should Be Provided?
Buyers should provide 2D PDF drawings and 3D CAD files whenever possible. STEP, IGES, or X_T files are preferred for manufacturing review, while PDF drawings define tolerances, datums, critical dimensions, material notes, heat treatment, surface finish, coating requirements, and inspection standards.
For power generation turbine replacement parts, assembly references are also useful because turbine repair parts often need to fit with adjacent blades, vanes, shrouds, casings, liners, transition pieces, seals, rings, or mounting hardware. Assembly information helps the supplier identify functional surfaces and avoid quoting based only on isolated geometry.
File Type | Recommended Format | Quotation Value |
|---|---|---|
2D drawing | PDF with tolerances, datums, material, heat treatment, coating, and inspection notes. | Defines acceptance criteria and quality-control requirements. |
3D CAD file | STEP, IGES, X_T, or other solid model format. | Supports process review, tooling design, machining planning, and cost estimation. |
Assembly reference | Assembly drawing, mating part information, installation sketch, or photos. | Helps identify functional interfaces, clearances, and mounting features. |
Revision information | Latest drawing revision, old revision notes, or customer change record. | Prevents quoting obsolete geometry or outdated requirements. |
3. What Sample or 3D Scan Data Is Useful for Quotation?
If complete drawings are not available, old samples, worn samples, 3D scan data, CMM reports, and photos can support quotation and reverse engineering. These inputs are especially useful for obsolete turbine spare parts, discontinued models, emergency repairs, or power plant maintenance programs where the original OEM documentation is incomplete.
When quoting from samples, NewayAeroTech needs to distinguish original design geometry from wear, corrosion, oxidation, coating loss, cracks, deformation, and service damage. 3D scan data can capture complex surfaces, while CMM data is more useful for precise datums, holes, sealing faces, mounting surfaces, and functional dimensions.
Sample / Scan Input | Recommended Details | Why It Helps |
|---|---|---|
Old sample | Physical part, sample condition, service history, and whether it is worn or unused. | Supports direct measurement, material testing, and reverse-engineering review. |
Worn sample photos | Photos of all sides, cracks, worn areas, holes, edges, sealing faces, and coating condition. | Allows initial feasibility review before sample shipment. |
3D scan data | STL, point cloud, scan report, or comparison file. | Captures freeform surfaces, airfoils, shrouds, liners, and complex geometry. |
CMM report | Datums, hole positions, sealing faces, mounting features, and critical dimensions. | Defines precise inspection and manufacturing references. |
Damage information | Cracks, oxidation, erosion, warping, coating failure, wear marks, or missing features. | Helps identify whether the replacement part needs geometry compensation. |
4. What Material Information Is Needed for a Turbine Spare Parts Quotation?
Material information is critical because turbine repair parts may use nickel-based superalloys, cobalt-based alloys, titanium alloys, stainless steels, heat-resistant alloys, or customer-specified materials. Buyers should provide the original alloy grade, equivalent material requirement, heat treatment condition, coating requirement, operating temperature, and any material report if available.
If the original material is unknown, sample material analysis can help identify the alloy family. However, final material selection should consider the part’s operating position, temperature, load, oxidation exposure, wear condition, coating system, and customer approval process.
Material Information | Recommended Input | Quotation Impact |
|---|---|---|
Alloy grade | Inconel, Rene, CMSX, Hastelloy, Stellite, Nimonic, titanium alloy, or customer standard. | Determines material cost, process route, heat treatment, and machining difficulty. |
Heat treatment | Required condition, customer specification, or supplier-recommended route. | Affects material properties, lead time, inspection, and documentation. |
Coating requirement | TBC, oxidation-resistant coating, wear coating, coating preparation only, or no coating. | Affects surface preparation, coating allowance, inspection, and final dimensions. |
Operating temperature | Maximum temperature, continuous temperature, and thermal cycling condition. | Helps evaluate alloy suitability and post-processing route. |
Original material report | Material certificate, chemical analysis, or old part testing report. | Supports equivalent material review and traceability planning. |
5. How Do Quantity and Project Type Affect the Quote?
Quantity and project type affect tooling strategy, unit price, lead time, inspection level, and manufacturing risk. A one-piece reverse-engineered prototype may require more engineering work per part, while a repair batch or annual spare parts program can spread tooling, fixture, and process validation costs over more units.
Project Type | Recommended RFQ Information | How It Affects Quotation |
|---|---|---|
Prototype | Purpose, design status, test requirement, and expected next stage. | May require flexible manufacturing and engineering review before tooling investment. |

Repair batch | Quantity, outage schedule, delivery deadline, and part priority. | Requires production planning and batch quality control. |
Annual spare parts demand | Estimated annual usage, batch size, forecast schedule, and repeat order plan. | Supports better tooling, fixture, inventory, and unit-cost planning. |
Urgent outage project | Required delivery date, critical components, shipment method, and acceptable process route. | May require expedited engineering, production, inspection, and logistics planning. |
6. What Process Requirements Should Be Defined?
Buyers should define whether the required scope includes casting, forging, powder metallurgy, CNC machining, EDM, deep hole drilling, heat treatment, coating preparation, surface treatment, inspection, or finished delivery. If the process is not fixed, NewayAeroTech can recommend a route based on geometry, material, tolerance, service condition, and quantity.
For complex turbine repair parts, the manufacturing route may combine vacuum investment casting, superalloy CNC machining, EDM, deep hole drilling, heat treatment, and superalloy post process. The RFQ should clearly state whether the buyer wants a rough blank, semi-finished part, or fully finished replacement part.

EDM and deep hole drilling | Narrow slots, small holes, cooling holes, fuel passages, and difficult superalloy features. | Specify hole size, depth, slot width, surface integrity, and cleaning requirements. |
Post-processing | Heat treatment, HIP, coating preparation, stress relief, surface cleaning, or finishing. | Specify required records, coating allowance, and final dimensional condition. |
Finished delivery | Projects where the buyer wants ready-to-review or ready-to-assemble parts. | Confirm final machining, inspection, documentation, packaging, and delivery scope. |
7. What Inspection Requirements Should Be Included?
Inspection requirements should be included in the RFQ because they directly affect quotation, lead time, and documentation. Typical inspection items include CMM, 3D scanning, FPI, X-ray, CT, material report, heat treatment report, coating inspection report, FAI, dimensional report, and COC.
For hot gas path parts manufacturing, inspection may focus on airfoil profile, throat area, internal casting defects, surface cracks, coating readiness, and high-temperature material condition. For rotating turbine parts manufacturing, inspection may focus on material integrity, concentricity, NDT, heat treatment records, and balance-related geometry.
Inspection Requirement | What It Verifies | When to Request It |
|---|---|---|
CMM inspection | Critical dimensions, datums, mounting faces, sealing surfaces, and hole positions. | Precision machined turbine replacement parts. |
3D scanning | Freeform surfaces, airfoil profile, shroud shape, liner geometry, and CAD deviation. | Complex castings and reverse-engineered turbine parts. |
