Principles of materials choice:

1)High acoustic transmission ability.

2)Allowing for easy installation.

3)Lower charges.

The new series forcipressure type sonic log pipe is the latest products of ultrasonic test system.

With the new avoid welding technology, as long as using the special hydraulic pliers, pressing could be finished,save time.save effort,save charges,and can be installed successfully just one time. 

It will be more powerful to prevent leaking liquid,being disjointed than before,and easier to install than before,these advantages makes the new seires flange type sonic log pipe become the optimal product of ultrasonic test system.
