Pressed Stainless Steel Flanges
Pressed Stainless Steel Flanges
Quality & Certification
Our manufacturing partner operates under a certified Quality Management System that complies with the stringent requirements of the European Pressure Equipment Directive (PED) 2014/68/EU.
The certification confirms that the manufacturer has implemented and maintains a structured quality management system in accordance with recognized European standards, ensuring full traceability, compliance, and reliability in the production process.
The approved scope of certification includes the manufacturing of pressed loose flanges and pressed collars, supporting demanding industrial applications that require high-performance stainless steel components.
This certification demonstrates a continuous commitment to quality assurance, strict manufacturing control, and internationally recognized standards across all production processes.
TECHNICAL STANDARDS
Our pressed stainless steel flanges and collars are manufactured under a Quality Management System certified in accordance with
⦁ PED 2014/68/EU
⦁ AD 2000-Merkblatt W0, W2, W9, W10
TÜV Rheinland (Notified Body No. 0035).
What This Means for Customers
- Verified material traceability
- Regularly controlled and audited manufacturing processes
- Documented inspection and testing of the products
- Compliance with PED 2014/68/EU, Annex I - Essential Safety Requirements, particularly regarding the Materials for Pressurised parts and EN 764-5.
- Issuance of inspection certificate 3.1 according to EN 10204
- Certified compliance with EN 1092-1 mating dimensions
This certification framework helps ensure that our components are suitable for use in pressure equipment within applicable design limits, including applications at cryogenic temperatures.
Explanatory notes on key terms
Flanges and their joints: Steel flanges
Inspection documentation of metallic materials and compliance with the material specification.
⦁ W0 – Metallic materials – general requirements and principles
⦁ W2 – Austenitic stainless steels
⦁ W9 – Steel flanges
⦁ W10 – Metallic materials for low temperatures
70% Faster Installation
Self-aligning design ensures perfect gasket positioning and centered bolt holes every time.
Cost-Effective
Fraction of the cost of forged flanges. Only the collar needs welding, saving time and material.
Eco-Friendly
Reusable design reduces CO₂ footprint and steel waste. Only gaskets and collars are replaced.
Advanced Elastic Response
unlike conventional flanges, SWISS-STAHL pressed flanges offer a favorable elastic response.
- Protects gaskets from over-tightening.
- Acts like a spring washer to prevent bolts from loosening due to vibrations.
- Prevents long-term leaks in industrial piping.
Product Range
EN 1.4307 (AISI 304L) – EN 1.4404 (AISI 316L)
Independent Laboratory Validation
- ASTM E1003-13 – Hydrostatic Leak Testing Standard
Key Advantages Section
Faster & Easier Installation
- Self-aligning design ensures perfect positioning
- Gasket always sits correctly
- Bolt holes are perfectly centered
- Installation time reduced by up to 70%
Lower Costs
- Much more affordable than forged flanges
- Only the collar needs welding, not the full flange
- Easy modifications: reuse the flange, replace only the stub end
