Products
EZTM JSC has designed and delivered more than 70 continuous electric welding plants (CEWP) which operate in Russia, CIS and abroad (Germany, Brazil, ARE and etc.) with equal success.
To produce tubes from different steels and alloys as well as aluminum, titanium and copper the material is subjected to high-frequency welding with inductive and contact current supply and to inert gas arc welding.
Welded tubes produced in these plants can be successfully substituted for the more expensive seamless tubes in some branches of industry.
The plants consist of the following equipment:
- strip preparation lines;
- forming-welding lines;
- tube sizing and shaping lines;
- cutting and packing line;
- tube finishing line.

The equipment of the plants can be arranged in different ways depending on customer's need.
At the customer's request it is possible to equip the plants with devices for production of shaped tubes.
The plant can include a stretch-reducing mill which extends its design flexibility.
All tube-forming and tube-welding processes are fully automated.
