Re: [MW:35477] WPS for Furnace PWHT

The spools have 1" to 36" Piping joints.

The WPS with PWHT is available only for large diameter / high thickness.

can we do PWHT in the furnace if small size piping joints welded without PWHT WPS which is welding with higher size spools require PWHT?.

Re: [MW:35479] Welding of CS+Alloy825 clad pipies

HI SIR

I use E309 or E310 for buttering layers. Is it correct ?

I use ernicrmo-3 for root, hot, f1, f2 

then i use E309 in 2 layers

Completely with k7018 to the end. 

It can or can not do it?

Thank you for answering me.

Hope u have a great day

Hi Romiomdabre,

 

The default technique for such pipe spool (where welding from I/S is not possible) would be to use Inconel-625(E/ER-NiCrMo-3) fillers and electrodes all through. Yes this would make  cost of welding quite high. As you know these piping are exposed for extremely harsh service environments, proven welding consumables are required to meet the design and construction and service requirements. Typical offshore pipeline design specifications such as DNV-OS-F-101 indicates one "type" of welding consumable for single sides welding of clad pipes.

 

I would think there are  some alternatives practiced in the industry,  in the way of using Stainless/ Nickel Based alloys for clad welding + application a pure Iron barrier layer on the clad weld followed by welding with C.S electrodes on C.S base metal. The attached extract of 10064-Page2(15) Fig-26 shows the welding sequences. While this technique has been proven for welding of S.S clad C.S pipes, there had not been much information available on the same for welding of Inconel Clad pipes. The critical factors here is the availability of Pure Iron electrode and acceptance of the same by fabrication code. A sample from Lincoln Electric is attached for information.If any other forum members could shed some lights on this issue,it would be appreciated.

 

Incidentally similar query was raised in another forum,few years ago.I have attached the responses and discussions for

Complete weld with Alloy 625 will be very costly as the thk is high.

[MW:35481] Re: welding of cladded (alloy 625) pipes with single side access

dear sirs,

Cant use 7018 right after ernicrmo-3 finish. You must have butter in between, otherwise it will cause cracking. Thats for sure. We havent even mentioned the heating issue yet.

Hi Nikdin,

After buttering (around 1.5mm thick alloy 625 overlay), machine it and match both ID. Then weld the root and hot pass with GTAW (ERNiCrMo-3) then fill up passes with SMAW process. 

Dont deposit any carbon steel deposits on the groove. Even you use Carbon steel bullets for fit up will leads to crack of groove weld deposits.

Re: [MW:35483] Pipe Insert Sleeve - How to ensure after hydrotest No Water

Hi

The black 'O' Ring seals the gap between pipe and sleeve, 

Also a TK epoxy system "blue mastic" is applied all over the sleeve except weld area,

 After all this there will be no water entry during hydro test in the weld joint area,

How did you have ensured there is no water between sleeve insert and pipe?

Re: [MW:35452] Piping Butt weld joint resting on support

As per international standards:

ASME B31.3 (Clause 321.1.2, 321.1.3) – Piping joints should not rest on supports to prevent undue stress and allow inspection.

ASME B31.1 (Clause 114.3, 120.1) – Supports must not interfere with expansion or place stress on joints.

API 570 – Ensures accessibility for inspection and maintenance.

MSS SP-58 – Recommends support placement away from joints.

Re: [MW:35457] WELDER PERFORMANCE RECORD

Dear Team,

Sorry team, I think you have miss understood the question I have asked. Actually, I need a Welder performance record instead of a Welder performance qualification or a welder Continuity record.

WELDER PERFORMANCE RECORD is a document which is used to monitor the NDT results pass or fail percentage for each welder as per the project requirement which is even good to keep as a permanent record.

Re: [MW:35459] QW 451.1

As per ASME Section IX, for test coupons greater than 10 mm (3/8 inch) in thickness, side bend tests are required. Since your test coupon is 38 mm thick, side bend tests should be conducted instead of root and face bend tests.

The reason for this requirement is that side bend tests effectively evaluate the entire thickness of the weld, ensuring that any discontinuities across the weld zone are detected.

BR,

Dear experts,

Re: [MW:35459] WELDER PERFORMANCE RECORD

As per your requirement attached, the Welder Performance Record is used to track NDT results, including pass/fail percentages, for each welder based on project specifications. Hopefully this will serve your purpose.

Dear Team,

Sorry team, I think you have miss understood the question I have asked. Actually, I need a Welder performance record instead of a Welder performance qualification or a welder Continuity record.

WELDER PERFORMANCE RECORD is a document which is used to monitor the NDT results pass or fail percentage for each welder as per the project requirement which is even good to keep as a permanent record.

Re: [MW:35463] Hot tapping between piping and pipeline

Definitely, to qualify the procedure, you must follow API 1104 Annex B.

And by the way, our experience in hot tap fitting welding projects, on pipelines with gas flow, API 5L X60 pipe, Ø 12" and API 5L X70 pipe, Ø 16".

Dear Expert

we have hot tapping 

from process piping b31.3 design 

to cross country pipeline old pipe i think api 1104 design

WPS that need to folow  api 1104 or asme b31.3.

Re: [MW:35464] Hot tapping between piping and pipeline

Hello,  

ASME B31.3 is not having any references clause for HOT welding procedure qualifications. 

Yes, the fitting design shall be designed inline to B31.3 for process piping and the field welding of the fitting on the live system shall be done as per API 1104 . 

Note : In case of fitting fabrication, let say in barred tee the weld joint between flange and sleeve , the shop welding can be carried out inline to ASME section IX.
