RE: [MW:23238] Can Cement Lining be applied in field?

Normally only the lining near the joints can be preferably done at site and not the entire piping since the uniformity in lining thickness may not be achieved at site.

Thank you for this information. As far as GTAW is concerned we have much of expertise.

We had also enquired at DRDL,HAL etc. But they regreted.

For BARC, haven't enquired as I didnt get any contact. If u have any pl share.

If that also doesn't work, what u suggest? I think SAW to be carried.

Dear Mr.Sangamnerkar,

I doubt about the capabilities of EBWs available in India to meet your demand .For 3 to 4 meter diameter you have to use partial vacuum EBW system which works in open air .Such a facility was demonstrated by SCIAKY ,Frnace in 1776 if I remember correctly during my training at this facility and I participated in this programme. We welded 80 mm thich SS 316 vessel of dia same as yours .In this system the EBW gun will move along the vessel covering the joint area with a special partial vacuum system . OSAKA university people developed another machine in which the vessel is kept in a vacuum room and the beam is impinged on the vessel mounted on a rotary positioner .

For your immediate use please use normal TIG welding and a roller positioner rotate the vessel. Please inform your location ,vessel dimensions and code requirement .If you need an welding expert to visit you for procedure qualification with TIG please inform .

Dear kishor,

Hydrotest condition for the tank made up by API 650 is the requirements of carring out major repair means minimum 12 inch nozzle replacement or addition under the working height of liquid.
It means you don't have to do Hydrotest just do the pneumatic at 15 psig for reinforcement pad.

Re: [MW:23227] Re: EBW in titanium for T>50mm

Dear Mr.Sangamnerkar,

As a last attempt consult BHPV ,Vizag .They were working on Titanium .There was one firm presently called TEAM at Trichy started by Dr.Krishnamurthy Rao .They were doing some work in Titanium . You could ask WRI ,BHEL,Trichy for assistance. If you don't find any help please send your requirement and location ,I will check with an expert in this field living at Bangalore and seek his help if he is free.

Regards,

Sir,
Thank you for this information. As far as GTAW is concerned we have much of expertise.

We had also enquired at DRDL,HAL etc. But they regreted.

For BARC, haven't enquired as I didnt get any contact. If u have any pl share.

If that also doesn't work, what u suggest? I think SAW to be carried.

Thank you.

Dear Mr.Sangamnerkar,

I doubt about the capabilities of EBWs available in India to meet your demand .For 3 to 4 meter diameter you have to use partial vacuum EBW system which works in open air .Such a facility was demonstrated by SCIAKY ,Frnace in 1776 if I remember correctly during my training at this facility and I participated in this programme. We welded 80 mm thich SS 316 vessel of dia same as yours .In this system the EBW gun will move along the vessel covering the joint area with a special partial vacuum system . OSAKA university people developed another machine in which the vessel is kept in a vacuum room and the beam is impinged on the vessel mounted on a rotary positioner .

For your immediate use please use normal TIG welding and a roller positioner rotate the vessel. Please inform your location ,vessel dimensions and code requirement .If you need an welding expert to visit you for procedure qualification with TIG please inform .

Dear N.Lal ,

You are not mentioned the  degree of included angle.

Any how, by considering the angle is 60 degree , t=16 mm ,root gap =2mm and using downhill direction.The approx. no. of standard electrodes per meter joint shall be

Root Pass          - 3.15 dia.  - 7 pcs/mtr.

Filler +nup runs - 3.15 dia.   - 15pcs/mtr.

Dear kishor,

Hydrotest condition for the tank made up by API 650 is the requirements of carring out major repair means minimum 12 inch nozzle replacement or addition under the working height of liquid.
It means you don't have to do Hydrotest just do the pneumatic at 15 psig for reinforcement pad.
