    Visual inspection requirements for ASME B31.1

    and the 5% UT and RT does not release you from the 100% visual, as stated before there are reasons for these requirements I have never seen where the owner did not pay out the butt when he tried to save money on the inspection part of construction, I have been on several sites that ended up...

    Which standard stipulates UT inspection 24hrs after welding?

    I have searched ASME AWS and API, I cannot find where it sates in any of these codes that UT has to be completed in 24hours after welding has been completed, could have been a clients specification that you read to come up with this statement, do you remember who the client was ?

    Ever built a shipable storage tank?

    The heads were coned with stiffeners every 2' and I remember after the first post we added stiffeners inside and ran, I beam along the base between wheels I am sorry for the vague details but this was about 20 years ago, and we did not use computers to track everything, I wish we had these tools...

    Hydrotest Water quality

    They need to build a DI water skid there is some tank Manufactures that use this to keep chlorides down. 70 sounded high I have inspected some tanks in upstate NY and water, there were 35 ppm and I though that was high, I believe that the DI water was below 15ppm, and I will check if needed.

    Ever built a shipable storage tank?

    I have built tanks over the 50' mark. We had to lay them on their sides and weld the rear wheels to the tank,they had stiffing rings... there were a lot of restrictions like could only travel at night and need 2 escorts and as i recall a lot of state permits to pay off... I mean to buy. Tank...

    % x ray

    Ballbearing1 I agree but this whole thing is not that stright by using the b31.4 and B31.8 they dictate how much x-ray is required for those codes and refer to the part in API 1104 for rejections and repairs so if you read what the other 2 codes direct us to read it states this is up to the...

    % x ray

    1st. For inspection to the B31.4 code for rejections from X-rays you need to look at API 1104 according to 434.8.5 welding Quality in the B31.4 API 1104 states that all rejected area need to be replaced and re-inspected with same method of 1st inspection and any other inspection is at discretion...

    Pipe fittings inspection

    I would hire third party inspection company to go and do a shop audit, and then you will get the information you are looking for, plus they have nothing to gain if the shop is not up to your standards... there would not be empty promises from a vendor that wants your business.

    Surface Rougness Cutoff Length

    What are you meaning by "cutoff lengths"? What type of instrument are you using for measurements? Do you have control of the instrument to be able to control the travel over the surface, if so what are the increments of travel? Thanks

    Max No of cylinder to be chained up?

    Rule of thumb... if it looks un-safe then it probably is... you must have some concerns or you would not have posted take the time and make it safe... remember if you did what needed to be done, then no one will ever know, if you don’t then everyone will know... just something to think about
