The EZTM Joint Stock Company designs and deliveres the flowlines of tube finishing (FLTF):
· commercial tubes;
· oil pipes (tubing, casing, drill, pipes for geological servey, oil piping);
· boiler tubes;
· other types of tubes from carbon steels.
The flowlines manufactured by the EZTM Joint Stock Company are the most perfect and effective. They are notable for high output. The lines allow to finish the small diameter thin-walled tubes. The manufactured tubes are notable for high quality. Production process is effected according. to the principle of continuous flow beginning from the charging of billets and ending in the tube finishing. Each technological operation is mechanized and automated completely.
Recommended standard sizes by tubes diameters: FLTF 80 (for tubes with Ø 20-89 mm ), FLTF 100 (for tubes with Ø 30-108 mm) , FLTF 170 (for tubes with Ø 60-168 mm ), FLTF 350 (for tubes with Ø 146-325 mm ).
