To Detect Flaws in Scaffolding Systems (Tubular)

you can use x-ray apparatus to view its flaw directly. of cuase you can also use eddy testing to determind if the tube has a flaw as well. These two methods are all better than testing in UT for such size of tube.
If you need futher help please let me know, maybe i can help you from detecting to instruments.
where are you from ? and whats your emailbox?

Best bet is to search companies that make ultrasonic methods of testing in general. They will have made equipment to test tubes as well as welds etc.

xray is also good, but the risks of xrays mean you need licences and operators who are also licensed in most places.

X-rays are often used in manufacturing.

There are a number of places that sell x-ray sources you place in a pip and you wrap it with film and later examine it for flaws. Pipeline companies use them

Ultrasound can be used in real time with a CRT or LCD screen and you look for reflections from flaws cracks etc.

It would help if you said whay and what your need is for?

Hi,#2 friend, You have a good view point at x-ray detecting. Its very direct view of flaw detecdting and easy use. Not only use film to develop but can use real image system for instant watch. Its also safe and fast detecting. It can watch 3--6 tubes at one time for small 6" screen or more tubes for more size screen, for instance, 9" and 12" depend of your work speed at the site. It s suitable for any longth tube. generally speaking, all tube will be in 12M,15M and 25M max. Picture can be stored, printed and reviewed at any time for inspection. This is only very low voltage and x-ray intensity. Of cause You can also use it for large tube, says, more than 20" etc. Generally speaking, we dont use ultrasonic tester for such small tube's inspection. one side, its very trouble moving probes every time and important, it will has a special blind zone for thin wall thichness. Thats why I dont recommend this method. Just opposite it. the EDDy can serve as a vey good tool for this kind of tube inspection. it can use for both single tube inspecting and produce line inspecting. operation is also easy. However, both ut and et are all qualified. #1 friend We can offer you all above equipments (et,ut,rt). from trainning to qualification of II.

Thanks for your explanation.I am from Brazil,exactly in Casa Branca,São Paulo State .

I'm working for ROHR Industria e Comercio Ltda,that manufacture scaffolding systems made of steel tubes.
