Dear all, Is there any european or american procedure elaborate about tier 1 and tier 2 mechanical or equipment inspection? If yes, could share me the procedure title.thanks in advance.

Dear all, need to get second opinion. I have an issue where we found out a high number of welds having Lack of Side Fusion and have been there since 5 years ago, a poor QC contribute to this.Currently we plan to re - inspect back using UT scan and also RT since we only can repair it next year...

Dear all, i would to get an advise. Have anybody experience super DSS shaft repair using monel metal spray on damaged area od shaft. The shaft will be used for seawater pump. Unfortunately, there is no super DSS material for metal spray. Appreciate any feedback.

Dear all, i have one situation where sacrificial anode Al-Zn-Ln is somehow generates a carbon monoxide gas within 30 to 100ppm, when we used gas detector near to it . The anode is submerged in seawater tank and there is a salt covering it. The anode still in good condition with no sign of...

Dear all, I would like to known is there any different between CP dipcheck (potential survey using reference anode) with underwater CP survey on structure and pipeline which the reading is taken directly from the substrate. Some say that CP dipcheck is very important in eveluate the estimated...

Dear all, we plan to connect carbon steel line with a main line which is duplex stainless coming from skimmer pressure vessel. I have done the calculation on partial pressure for H2S and it is lower than 3.5 mbar. My question is, can we use Carbon steel pipe such as 516 or A333 to connect to...

Dear all, Need some advice, we have localized corrosion with heavy scaling on the pipe body. We unable to remove the scaling to access the remaining thickness and thinking of doing temporary repair while plan for permanent repair in incoming shutdown. 1. Do we have a temporary repair as per...

Hi, Anybody have experience doing ultrasonic A,B or C scan on the glasflake coating (1000 micron) on the riser to determine the internal conidtion of the riser since the IP cannot be performed on schedule due to operation/process problem. if ultrasonic scans are not the option, any other proved...

Gents, I have a carbon steel vessel with unknown grade and I need to repair a localized corrosion with 7mm depth and size (length & witdth) are 60 mm on the head side. Remnant thickness is 2.2mm & required thickness is 1.6mm.Nominal thickness is 9.525mm. Any rule of thumb of what type of...

Hallo respective engineers, Do we need to have ASME or maybe API certified repair company in order to repair ( alteration/heat input such as weld build up) for a vessel which fabricated using BS/PD 5500 (since this code is the same level with ASME VIII Div. II)?Is the approval by the...

Gents, please advice if generally we cn say that high or excessive velocity is direct proportional to the vibration of the piping in the gas system?

HIiiiiii.... Anybody ever used successful NDE technique to check the gasket in the RTJ flange during operation. I have concern if the gasket is CS in the SS piping.Please advice.

Hi all, Does anybody have a good or bad experience using ultrasonic measurement wall thickness from inside the insulated vessel ( in case we cannot strip of the insulation due to short shutdown duration and limited manpower). Is it okay from inspection engineering view and is the result...

Hallo, Just want to ask, can we perform UT on the incoloy material without calibrating it with incoloy 825 calibration block but using CS calibration block as a reference and then adjusting the wave velocity in the UT equipment itself as we know the wave velocity for incoloy 825. Any reference...

Folks, Any body have a bad experience with insulbag? When is the best inspection duration to inspect component with insulbag, is it 5 yearly appropriable or maybe need to be reduced? Do I need to do thorough inspection meaning that I have to open the insulbag to check the condition of the...

Hallo, I need simple help, I ahve problem with leaking of liquid from tube header. Beside replacing the new plug ( if the internal threaded still ok) or welded the plug ( last option and will provide no more option for instrusive inspection), is there any new techniques or applications (such as...

Gents, Anybody can advice what is the suitable coating for vessel which operate more than 130 degree celsius, medium is lube oil and have a pitting problem in it. We suspected the lube oil is not clean/ contaminated.Thanks
