One-off to medium batches
Key materials
316L, nickel alloys, PTFE, PP
Pressure equipment
PED where applicable
Certificates
EN 10204 3.1

Overview

Chemical processing equipment must resist aggressive media while staying safe and cleanable. Typical parts include tanks and vessels, agitator parts, heat exchanger components, pump and valve parts, lined piping and machined plastic components.

Türkiye’s stainless fabrication, machining and plastics processing base serves chemical, paint, detergent and fertiliser producers across the region.

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

Material selection is the key decision in chemical equipment. The process media, concentration and temperature determine whether stainless, a nickel alloy or an engineering plastic such as PTFE or PP is suitable, and that choice narrows the facilities that can actually make the part.

Typical parts & components

  • Stainless tanks, vessels and agitator parts
  • Heat exchanger components
  • Pump casings, impellers and shafts
  • Valve bodies and trims
  • PTFE and PP machined parts and linings
  • Piping spools and fittings
  • Filter housings and process skids

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

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.

  • ISO 14001 Common

    Often requested by chemical producers.

  • ISO 45001 Sometimes requested

    Occupational health and safety.

Standards & regulations

  • Pressure Equipment Directive (PED) Common

    EU Pressure Equipment Directive.

  • EN 10204 Type 3.1 Typically required

    Material certificate for metallic raw material.

  • REACH Common

    Substance compliance in the EU.

Quality & documentation

  • Material certificates to EN 10204 3.1.
  • Welding to qualified procedures; pickling and passivation after welding.
  • Pressure testing and PED compliance where applicable.
  • Material compatibility with the process media documented.
  • Surface finish specifications for cleanability.

Typical tolerances & surfaces

  • Machined pump and valve parts: typically ±0.02–0.05 mm.
  • Welded vessels: tolerances per the design code and drawing.
  • Plastic parts: tolerances must allow for thermal expansion.
  • Internal surfaces: roughness specified for cleanability, e.g. Ra ≤ 0.8 µm.

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.
  • State the process media and temperature so material suitability can be assessed alongside the drawing.

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. welding or CNC machining), the specified material and grade, and requirements such as PED.
  • 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

100 PTFE valve seats and 20 Hastelloy stems — FCA.

  • The buyer uploads drawings for valve seats and stems for aggressive chemical service.
  • Metraxio structures the requirement: CNC machining, PTFE and nickel alloy C276, 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

How do I make sure the material suits my media?

State the media, concentration and temperature in your project. Material selection remains the buyer’s responsibility, but it helps suppliers flag concerns early.

Can suppliers machine PTFE and other fluoropolymers?

Yes, many machining shops process PTFE, PVDF and PP. Material is part of your requirement.

Is PED compliance required?

For pressure equipment placed on the EU market above certain pressure and volume limits, yes.

Are pickling and passivation included?

They are common after welding stainless steel; list them as secondary processes.

Are supplier names visible during the assessment?

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