Devices for tube wall solidity and other devices are manufactured by home and foreign companies.
Mechanisms for tube transfer and transportation have been made for exclusively effective equipment arrangement, are durable, reliable and have high output.
We give as an example a technical characteristic of a delivered automated flowline for control of tube wall solidity with diameter of 38-168 mm of Ferro magnet steel grades.
