7.Competitive Advantage:

■ We have more than 10,000 square meters workshop, including 10 extrusion finning machines, daily extrusion capacity up to 3,000 Meters.

■ The extrusion finning machines are designed and assembled by ourselves and we can offer you finning machines, extrusion muff sleeves and all accessories (extrusion finning disks) etc...

■ DR-extruded bimetallic fin tubes maximum operating temperature: 300 degree. The transfer coefficient remains steady.

■ DR-extruded bimetallic fin tubes have stronger fins than other mechanical fins, like L, LL, KL, and G, so it is much easier to clean.

■ In application of high stress and corrosive condiction, DR-extruded bimetallic fin tubes provides an excellent technical and economical savings in comparsion to a costlier single alloy tube, as the use of costlier material is reduced to the min.
