RE: [MW:12353] 3.2 Certification Query / EN 10204:2004

Dear all,

For me it seems unusual to require 3.2 certificates on pipe fittings, so first of all it would be worth to ask the client, if that is really what he want.

Regulations for pressure equipment as well as recognised standards would normally only require 3.1 certificates, but of course a client/plant owner may have stronger requirements for some reasons.

 

Secondly, if the 3.2 certification is a wish from the client to ensure 3.1 certificates has not been falsified, you could propose a scheme including PMI (Positive Material Identification), to verify the correctness of 3.1 certificates, as an alternative to the requirement for 3.2 certificates.

 

However, you will first need to understand what is behind the requirement for 3.2 certificates.

 

regards

Kristian

Dear All,

 

We would like to know whether Pipe fittings (Elbow, Tee, Reducer etc…) can be certified to 3.2 Certification from the Base material which is a pipe.(Base material Certificate type is 3.1) and help us by providing what all testing and other requirements to be considered in Inspection Test Plan for Pipe fittings to be endorsed as Type “3.2”.

 

Whether physical traceability of base material (in our case, it is carbon steel seamless pipe) at Manufacturer’s location is required?

 

NOTE: All mechanical and chemical tests for fittings at an Independent Laboratory shall be done and will be certified by LR, BV etc…. so as to endorse Pipe fittings as “3.2 Certification”.

Do we still require a complete traceability of Base Material Certificate; although above test will be done?

 

Please provide your technical guidelines to resolve above query.

 

Hope to see as usual positive response from eveyone.

 

Thanks & Regards

Vino Doha, Qatar
