7	1	On the magneticle particle examination, you mention cracks below the surface can be detected. What is the depth limit for detection? Does it depend on the magnetic field being generated?	Tom Marreel	It is hard to give a definitive answer other than "near the surface". Yes the strength of the magnetic field generated will influence the result.
8	2	Which specific parts of the pump are required to undergo UTE inspection? Would it be acceptable if the inspection is conducted only at the nozzle area?	Ilham Maulana Arfah	See Table 14 (in slide 70) for identification of what Inspections are required for which components of the pump. It is largely to do with pressure containing parts. Scroll Left >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
9	3	Which specific parts of the pump are required to undergo UTE / RT inspection? Would it be acceptable if the inspection is conducted only at the nozzle area?	Ilham Maulana Arfah
10	4	Can you shed some light on PAUT/TOFD? is it better than RT?	Anonymous Attendee	The following article may help understand this field https://ndt-kits.com/tofd-and-paut/
11	5	Do Plan 11 and 52 (as example) specified as auxillary piping and should be inspected accordingly?	Ruslan Sagitov	Yes. Seal piping is auxiliary process piping
12	6	Thank you for this very useful course, I have one question: is UT equally effective on painted surfaces?	Anonymous Attendee	Yes UTE can be used on painted surface. Loose paint should be removed.
13	7	For a specific material such as (Super duplex and duplex materials), are there any tests such (corrosion, ferrite, hardness and so on.), even if the customer doesn't require	Abdallah Hassani	These properties will all be detailed in the Material Test Report (Material Certificate). The NDE we are discussing here is in reference to the quality of the castings and the welding.
14	8	What type of test should be done for a pump casing drainage nozzle? same as succion or pressure side nozzles?	milagros antunez	Per Table 14 this would be an Auxiliary connection weld.(scroll left) >>>>>>>>>
15	9	API 610 indicates The Class 2 inspection requirement for ">80% MAWP and >392°F". What shall be greater than 80% MAWP? Is it Rated Discharge Pressure or Max. suction pressure and Shutoff pressure (including testing tolerances)?	Anonymous Attendee	Several of you asked similar questions. So I have revised the presentation to better address the subject. See attached Slides 70-73 from the revised Presentation
16	10	what is the appropriate NDE method for connection welds(set on type)?	Anonymous Attendee	See Table 14 Auxiliary Connection Welds (scroll left)
17	11	is any standard about depth or length of crack still can be used ? because my customer still want to used the parts	Rizki Rajab Priangan	Per API610 Table 15, ASME Boiler & Pressure Vessel Code (BPVC) Section 8 gives the acceptance criteria for any defects that the NDE reveals. If they are non-compliant then weld repair can be carried out followed by further NDE to ensure the quality of the repair.
18	12	For Asia (Indonesia) how long deliverable need?	Wahid Imawan	LPE or MPE will not significantly add to the lead time. UTE & RXE of the castings can extend delivery time by several months! If you specify radiographic inspection of castings you restrict the choice of foundries to those that have in-house RXE inspection facilities (usually the most expensive foundries with the longest lead times) So only specify it when you really need to and are prepared for the cost and lead time implications
19	13	Is an impact test always performed on the API 610 pumps or only below a certain temperature? Clause 6.12.4.5 specifies that impact testing shall be done for CS and low alloy steel pressure retaining parts with temperature between -29°C and 38°C. Here, 38°C appears to be very high and may imply impact testing requirement for almost all the pumps. Is my understanding correct?	Anonymous Attendee	Scroll left for clause 6.12.4.5 >>>>>>>>>> Applying the entirety of this clause means that only pumps in Low Temp applications will need impact testing. Most pumps at 40C will be exempt.
20	14	Do API 610 accept EN standard also?	Anonymous Attendee	Yes
21	15	if you find a defect in the percentage extension i.e. in the 10% can you request to extend for the 100% especially if it is a non accettable defect the one you have detect in that 10%?	CARLO MARIA DI FELICE	Yes. If, for example, you are RXE testing 5% of the welds in the auxilliary process piping and one or more of them fails, it is reasuonable and usual to require additional welds to be tested.

30	1	Hi Simon, Thank you for the nice presentation. LPT procedure is done on final machined castings or raw castings.	Muhammad Usman	Both would be my answer. Firstly at the foundry to see if there are any surface indications that warrant excavation and possible welding. Then on the finish machined casing to see if machining has uncovered any flaws that were not visible on the raw casting.
31	2	How to UT test rounded surfaces?	Anonymous Attendee	If the curve radius is small you probably need a curved transducer.
32	3	Hi, Can we do UT on parts having cavity inside like volute casing.	Muhammad Usman	Yes. Because you will be investigating a small area of the casing wall at a time working your way all the way around the casing. You are not testing the whole casing in one shot.
33	4	Hi, In case only one condition for table 14 Class II is present like rated pressure is 80% of MAWP however temperature is less than 200 deg C, in that case Inspection Class II will be applicable or not	Muhammad Usman	Both conditions need to apply in order to make Class 2 inspecion mandatory per API610. (So rated pressure >80% of casing MAWP and T>200C) Of course the customer can overrule this if he wishes and ask for Class 2 inspection at a lower threshold.
34	5	Also same question as asked for LPT, is RT done on raw castings or it can be done on machined castings also	Muhammad Usman	RXE is best carried out at the foundry on the raw casting. It will show all defects within the casting. There would be no benefit to repeating RXE on the finish machined casing as there cannot be any new flaws to uncover.
38	9	Also one general question, can we perform the post weld heat treatment of final machined castings like BB3 or BB4 pumps.	Muhammad Usman	Post weld heat treatment would normally be carried out before final machining. If you carry out weld repair on a casting you will normally need to perform post weld heat treatment. If the weld repair was on a finish machined casting and is adjacent to a machined surface, it may well require remachining of already machined surfaces as the PWHT may have distorted the case slightly. This might then require weld overlay prior to this remachining. Sometimes LPE/MPE is carried out on a "nearly finish machined" casing to avoid this risk. There are also weld procedures available that do not require PWHT
39	10	For PT to be applied. Does API 610 allows also to consider Cracking Cromium-Nickel screen (Use of Fluorescent)?	Oliver Valadez
40	11	LP Root Pass of Full Penetrating Welds. Is that a BPV, API or Customer Specification	Jamie Hernandez	This sounds like a customer requirement to me. It is not an API requirement
41	12	Is there a rule about the frequency to execute the essays tests?	Alexandre Coccia de Souza	The number and locations of the radiographic or ultrasonic "shots" and areas to carry out LPE or MPE would be agreed in advance with the customer. Sometimes having agreed in advance "10% of welds to undergo UTE" it will be agreed with the customer inspector on site who might say "let's have shots here, here and here"
42	13	Does Helium leak testing is allowed also by API 610?	Oliver Valadez	I have not come across this requirement for pumps. It is usually applied on items that are hermetically sealed zero leakage. Pumps are controlled leakage not zero leakage.
43	14	Excellent session Simon , very complete and very understandable. Thank you very much	Oliver Valadez	Thank you for your comment and thankyou for attending
