Overview

Power generation equipment — turbines, generators, boilers and balance-of-plant systems — relies on large, precisely machined and fully documented components. Typical parts include turbine casings and blades, shafts and couplings, boiler pressure parts, heat-recovery components and maintenance spares.

Türkiye operates a large and diverse power-plant fleet and has a supplier base for heavy machining, pressure-part fabrication, forging and plant maintenance services.

On Metraxio you describe the part, attach drawings and state material, design code, quantity and certifications. The platform structures the requirement and shows which facilities are a technical fit.

Power generation parts are often replacements for installed equipment, where matching the original material, dimensions and documentation is critical. Providing drawings or samples, the material grade and required test reports lets facilities be assessed against the real duty of the part.

Typical parts & components

  • Turbine casings, diaphragms and blade rings
  • Shafts, couplings and bearing housings
  • Boiler tubes, headers and pressure parts
  • Heat-recovery and heat-exchanger components
  • Generator frames and machined parts
  • Valves, fittings and piping spools
  • Outage and maintenance spare parts

The processes, materials and requirements below are an editorial reference of what is typical for power generation programs — not a statement about facilities in the Metraxio network.

Common manufacturing processes

Typical materials & grades

Certifications & compliance

What buyers in this industry commonly ask suppliers for. Exact requirements depend on the program, customer and part.

Supplier certifications

  • ISO 9001 Typically required

    Baseline quality system.

  • ISO 3834 Common

    Welding quality system.

  • ASME U Certificate Sometimes requested

    For ASME pressure equipment.

  • ISO 19443 Sometimes requested

    For nuclear-sector supply chains.

Standards & regulations

  • Pressure Equipment Directive (PED) Common

    EU Pressure Equipment Directive.

  • EN 13445 Sometimes requested

    European pressure vessel standard.

  • EN 10204 Type 3.1 Typically required

    Material certificate for metallic raw material.

  • ASME BPVC Section IX Common

    Welding qualification.

Quality & documentation

  • Pressure parts to PED, EN 13445 or ASME as specified.
  • Material certificates to EN 10204 3.1 or 3.2.
  • Welding to qualified procedures with NDT.
  • Heat treatment records and hardness testing.
  • Complete manufacturing data books.

Typical tolerances & surfaces

  • Rotating parts: runout and balance quality specified per drawing.
  • Large machined parts: typically ±0.02–0.05 mm on fits.
  • Pressure parts: dimensions per the design code.
  • Blade and seal profiles: tight tolerances and controlled finishes.

Sourcing from Türkiye

Türkiye combines a deep contract-manufacturing base with short routes into Europe. Industrial goods move between Türkiye and the EU under the customs union, so buyers typically avoid EU import duties on qualifying parts.

  • Many European destinations can be reached by road within several days; actual transit depends on origin, destination, customs handling and cargo.
  • Common delivery terms are EXW, FCA and DAP; Metraxio keeps the agreed Incoterm attached to the quotation and order.
  • Outage parts are time-critical; include the outage window so lead time is part of the assessment.

How Metraxio qualifies suppliers

Every request is checked against each facility's structured profile before any supplier is invited.

  • Hard criteria: the required process (e.g. heavy CNC machining or welding), the specified alloy and grade, and certifications such as ISO 3834.
  • Missing data is not a rejection. If a facility profile does not yet state something, the result is "Needs More Information" rather than "Not Qualified".
  • No match yet? You can continue with Managed Sourcing and the Metraxio team runs supplier discovery for you.
  • Facility identities stay anonymous during the technical assessment.

Example project

How a typical request moves through Metraxio

6 steam-turbine seal rings — 410 stainless — delivered FCA before the outage.

  • The buyer uploads drawings and a sample description for replacement seal rings.
  • Metraxio structures the requirement: CNC turning, stainless steel 410, EN 10204 3.1 and FCA delivery.
  • The fit assessment shows which facilities are qualified, which need more information and which do not match.
  • The buyer invites qualified facilities to a Supplier RFQ, or hands the job to Managed Sourcing.

Frequently asked questions

Can suppliers reverse-engineer worn parts?

Some can measure and re-draw parts. Drawings with material specifications give the most reliable results.

Are large machined parts possible?

Yes, facilities with heavy lathes, boring mills and portal machines handle large casings and shafts.

Which documentation is expected?

Material certificates, weld and NDT records, heat treatment reports and dimensional reports, often in a data book.

Can I get parts for an upcoming outage?

If material and capacity are available. Include your outage dates in the requirement.

Are supplier names visible during the assessment?

No. Facilities are shown anonymously during the technical assessment. Identities are shared as the engagement progresses.
