Continuous process and highly-productive equipment are developed for production of high-precision cold deformed electric welded tubes with regulated mechanical properties by cold reduction during co-operation with welding-and-forming line.

Tube welding aggregate ТЭСА 5-16 allows to produce tubes with diameter 5 - 16 mm, accuracy 0,01 - 0,02 mm by outer diameter and wale thickness up to 2 min. That is unique development for unit of this tape and has no analogs in the world.

Layout of unit ТЭСА 5-16

1 - uncoiler; 2 - roller guide; 3 - complex for arc welding of sheets; 4 - pinch rolls; 5 - strip accumulator; 6 - strip cleaning machine; 7 - S-shaped stand; 8 - set of synchro; 9 - forming mill; 10 - welding device; 11 - cooling bed; 12 - tube reducing mill; 13 - flaw detector; 14 - machine for tube cleaning; 15 - station for tube bundling; 16 - drive pulling stand; 17 - straightener; 18 - flying saw; 19 - acceleration stand; 20 - station for tube removal to pockets.

Cooperation proposals:

• Manufacturing of equipment;

• Tests and mastering equipment at the customer;

• Organization of co-production.
