When choosing an RTJ flanges supplier, it’s important to make sure they provide quality products that meet industry standards. One of the best ways to check this is by looking at the certifications they hold. Certifications show that the supplier follows proper rules, uses good materials, and makes products that are safe and reliable.
In this blog, we will explain the common certifications you should expect from a trusted RTJ flanges supplier.
1. ISO 9001 Certification
This is one of the most important certifications. It means the supplier has a proper quality management system in place. It shows they follow steps to make sure every product is checked and made with care.
Why it matters:
-
Ensures quality in every flange
-
Reduces the risk of defects
-
Proves the company is reliable
2. Material Test Certificate (MTC)
This certificate proves that the material used to make the flanges has been tested. It includes details like chemical composition, mechanical strength, and heat number.
Why it matters:
-
Confirms the flange material is strong and safe
-
Helps track the source of the material
-
Required for many industrial projects
3. Pressure Testing Certificate
An RTJ flanges supplier should test their flanges under pressure to ensure they won’t leak or break. A pressure testing certificate proves that the flange has passed these tests.
Why it matters:
-
Ensures safety in high-pressure systems
-
Reduces the chance of system failure
-
Required in oil, gas, and chemical industries
4. PMI (Positive Material Identification) Report
This report confirms the exact grade of the metal used. It checks if the right material was used for the flange.
Why it matters:
-
Prevents mixing of wrong materials
-
Ensures the flange meets client requirements
-
Useful in critical applications like refineries or power plants
5. Third-Party Inspection Certificate
Some projects require a third-party inspector to check the flange before shipping. This certificate proves that someone independent has verified the quality.
Why it matters:
-
Adds extra trust in the product
-
Required in government and international projects
-
Helps avoid costly mistakes
6. EN 10204 Certification (Type 3.1 or 3.2)
This is a standard format for test certificates in Europe and many other countries. Type 3.1 is issued by the manufacturer. Type 3.2 includes inspection by an independent authority.
Why it matters:
-
Accepted worldwide
-
Ensures full testing and inspection is done
-
Makes export and approvals easier
7. ASME and ASTM Compliance
A good RTJ flanges supplier should follow ASME and ASTM standards. These are widely accepted rules for how flanges should be made, tested, and measured.

Important for safety and durability
Conclusion
Choosing a certified RTJ flanges supplier gives you peace of mind. Certifications prove that the products are made with care, tested properly, and safe for use in demanding environments.
