There are two types of multi-lead rifled tubes Type:A and Type:B
with 30° helix anglr,these unique products can improve thermal efficiency by 30% in comparison to bare tubes.
It is used for power plant boilers,Multiple ribs greately increase the internal surface of the pipe compared to rib-less steel pipes,resulting in inreased boiler energy output efficiency.
Internally ribbed tubing helps to decrease mass flow ad ensures sufficient cooling for internal surfaces of tubes.
Common size:
60.3X7.5 8ribs
63.5X7.1 8ribs
Internally Multi-Lead Rifled Rifled Tube ,made by cold worked.
Raw material is from big steel mill like Bao Steel, ZhongTian, Shagang etc ,Tubes with several times cold worked.which has stable Mechanical properties on final product.
Key words:
Internally ribbed tube
multi lead rifled [MLR] tubes
Rifled boiler tube
Rifled tube
