Re: [MW:28936] IF ans IFD as per API 1104

AUT is mandatory by Client spec.

And Client spec not accepting Lack of fusion. 

We are getting Lack of Fusion and LFD on almost every joint.  Intention of post is to seeking justification for accepting LFD. Client telling as per API 1104 both IF and IFD are Lack of Fusion only hence needed to be CUT OUT and Rewelded. 

I am seeking advice from experts here to justify client regarding the acceptance of LFD

Hi,

Who told you to perform AUT? I mean why not RT? AUT will hold your project in Reverse gear.

Mostly in stringent case we perform AUT/PAUT/TOFD or where there is multiple requirement like tie-in's, anyhow it's mutual agreement between company and contractor.

And yes both are different by 9.3.4 / 9.3.5, ID and IFD, you cannot straight away reject but contemplate upon given para condition as per the pipe sizes then proceed for acceptance/rejections.

Thanks

Dear All,

Our Pipeline specification not accepting Incomplete Fusion .In case of incomplete fusion weld shall be rejected and re-welded.

But according to API 1104, IF and IFD are different . So is it required to reject both IF and IFD as both are incomplete Fusion?

Please help me with advice 

I am using AUT for the inspection and 70 % of joints are detecting either IF or IFD 

With Regards

Pls help me
