COLD FINISHED PIPES
Steel cold finished tubes are produced of carbon and low-alloyed steels. 

Tubes are intended for the production of submersible motors and electric pumps, hydraulic props, mecha nized jacks and they are used in robotics, etc. 

Tubes are delivered 3 to 9 meters long in bundles. Tubes can be coated by anti-corrosion preventive compound. 

Technical requirements are similar to those in ASTM A53 Grade B, 
ASTM A106 Grade A,B; DIN 2448/17121, DIN1629-84 and DIN 1630-84 St.37, St.44.
