SG12B is a hot reducing machine for heater tubular design and manufacture by Tubemachines (FeiHong), the transmission bed is similar as OAKLEY (American) transmission bed, however the roller assembly is as well as CSM (Italian) roller assembly. Tubemachines design and make the pipe reducer machines according to the requirement of the heater factories.

Speed of the output shafts of the twelve groups of gear cases has difference, which makes drawing to the tubes while reducing. Length of the tubes will be markedly increased after reduced by this machine, so it can save some materials. Tubes after reduced with smooth surface, roundness＜0.05mm. There are two materials of the roller wheel, one is the Cr12MOV or D2, the other one is hard alloy. Method of instilling lubrication can be chosen and auto stamping mechanism can be installed to the machine. With strong power, the machine can reduce heating tubes and complex materials with diameter up to 1 inch (Φ25.4mm).

Besides, SG12B is one of the pipe reducing machine for oblate heaters.

Features: 
1.Large power,single power can be 1.1kw,1.5kw,2.2kw;
2.Large torque,large power,more suitable for high density tubes, large tubes and long tubes;
3.Noise is a little large than A style machine. (similar as OAKLEY machine, speed down by gear);
4.The best reference range to shrink (mm): Φ4-Φ25mm (within the reference range, the life of the equipment will be longer).
5.Suitable tubes' material: copper, aluminum, iron, stainless steel etc.;
6.Suitable tube's shape: round tubes, flat tubes, oblate tubes, composite tubes. 
6.Shrinking speed: uniform speed,non-uniform speed (according to the demand of customer).
