[MW:31969] Re: SS 405 grains

These are straight Cr Stainless steels for high temperature application. In boiler , you can use this material. Pl. send what attachment part you are looking for ?

Re: [MW:31968] tanks

I think it will be SQR Butt weld preparation, there more penetration or some area no penetration without Backing Strip (BS). NDT Inspection it will be difficult in interpretation if no BS. API STD 650 spelled out BS required.  If no BS weld metal will touch the concrete base and prone to early corrosion . if you see other plates it will be weld as lap joint. Expert can add more points.  Thank you,  Regards,  S.SENTHILKUMAR On Thursday, 28 January, 2021, 10:53:24 am IST, hi.munu@gmail.com <hi.munu@gmail.com> wrote: Annalur plate area without backing strip can do welding , what about probleams came , anyone explain ? -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Mat...

Re: [MW:31960] Tolerance for straightness of the pipeline

No such drawing recommendation for straightness, the main need of LDO and HFO line are to be seamless pipes as these fuels having high sulphur content the sulphur ingress the crevice of the seam and over a period of time may cause leakage which is a high potential fire hazard during operation ( as you have mentioned IS 2062 please confirm whether it is seamless).   In recent days Indian power plants avoid use of HFO as the fuel - unburnt, lack of ignition, lack of purity and handling issues. And if the system is not put into continuous operation (even with recirculation and steam tracing) the whole system will get choked over a period of time and restoration would be mere impossible.     Regards, K.Pandiarajan.

Use Double operator GTAW  ie two welders welding from either side simultaneously in 3G, pulling same weld puddle with Square butt joint,  5 mm gap. Welders to practice first in 1 M long test plate. Use 2 or -2.4dia filler. 80/120 amps.  Provide stiffnars to act gap closing . 1stStriking arc welder to add filler in joint gap second welder to operate at lower current level and add filler as and when required moving arc behind 3-4 mm from first welder.

[MW:31955] Tolerance for straightness of the pipeline

Dear Experts, I want to approve an FQP for Pipe erection, and in that FQP I want to mention the tolerance limit for the straightness of the pipeline. I had also referred to relevant specifications and different codes including ASME B31.3 process piping but acceptance criteria is not mentioned anywhere. Pipe line belongs to Ash slurry, HFO/LDO, and service water pipe used in power plants and the material is IS 2062. Here I would like to clear that query raised to know the acceptance tolerance as per code in straightness of pipe line at final inspection. Please suggest on which basis I can mention the tolerance limit for straightness of the pipeline in FQP. -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.
