Re: [MW:25858] PWHT reqmt for welds as per API 6D

Regardless codes, your odds to succeed are minimal if you don not perform PWHT.

It is indeed mandatory for Pwht as per ucs 56 of sec viii div 1 for thk above 38 mm,& you should have pqr qualified with Pwht.

Dear Experts,
I have a Groove weld joint of thickness 40mm. The standard i need to follow is API 6D..
Welding procedures qualified under ASME sec.IX without PWHT with a test coupon of 50mm thickness of material ASTM A516 gr.70..
API 6D states " PWHT shall be performed in accordance with the applicable material specification or design code"
My material specification is ASTM A516 gr. 70 and Design code is ASME Sec.VIII Div. 1
A516 standard doesnt states welding or PWHT requirement, whereas ASME sec.VIII states - thickness above 38mm PWHT is mandatory..
Can i take the material specification to justify for not performing PWHT..
Please advise
With regards and thanks

[MW:25855] RE: 25854] PWHT reqmt for welds as per API 6D

Dear Vadival,

You have to comply with the requirements of the design code, which in this case is ASME VIII Div 1. That determines the application requirements, not the material specification.

Re: [MW:25851] RE: 25843] Welder performance for Temper Bead Welding

You have to find the way through the labyrinth of QW-290 in ASME IX

2016-12-27 7:05 GMT+02:00 pgoswami <pgoswami@quickclic.net>:

Hi Karthikeyan,

 

The default rule is ASME Sec-IX, QW-290. If  the applications are for pipelines, then you need to follow the guidelines of Piping Research Council(PRCI) also as additional resource.

 

Where this technique would be applied, and what's the grade of steel in question?

 

Appreciate your response.

 

Thanks.

One of the welder has been successfully completed his WQT as per API 1104 with the thickness 21.1mm followed by the the 21.1 to 31.935mm thickness range WPS. Is he eligible for below 4.8 to 19.mm (0.188" to 0.750") if he cannot weld the lower thickness, why?

In API 1104, thickness is essential variable

I am expecting a favorable reply... thanks in advance...

Dear Experts,
Have a nice day to you all... I have doubt about welder qualification thickness range.

One of the welder has been successfully completed his WQT as per API 1104 with the thickness 21.1mm followed by the the 21.1 to 31.935mm thickness range WPS. Is he eligible for below 4.8 to 19.mm (0.188" to 0.750") if he cannot weld the lower thickness, why?

In API 1104, thickness is essential variable

I am expecting a favorable reply... thanks in advance...

Krishnasamy. M

[MW:25847] Piping alignement tolerance as per ASME B31.1


Dear Experts,

Construction code - ASME B.31.1 (Fuel gas system)

Service - Fuel gas system

I wanted to know how much tolerance can accept  while doing piping alignment inspection like straightness checking , elevation checking dimensional checking etc

Nothing was mentioned in contract documents and project specification.

Please provide the reference.

[MW:25845] RE: 25843] Welder performance for Temper Bead Welding

Hi Karthikeyan,

 

The default rule is ASME Sec-IX, QW-290. If  the applications are for pipelines, then you need to follow the guidelines of Piping Research Council(PRCI) also as additional resource.

 

Where this technique would be applied, and what’s the grade of steel in question?

 

Appreciate your response.

 

Thanks.

Hi, You may select ASTM A707 F60 L3 as per 02-SAMSS-011, provided you should need to get approval from your customer.

Re: [MW:25841] E8018-B3L can be replaced with E9018-B3L

Yes you can use E 9018-B3, we have also used the same and the results are good. Make sure you do the proper preheating, maintain the interpass and also there is a posheat requirement for the P22 materials.
