Yangzhou Chengde (YC)
is one of the best pipe manufacturers in the world, and the production diameter
from 8" to 48" in OD and wall thickness from 9.53 mm up to 140mm. We can produce the A/SA53 steel pipes according to the ASME SA53 and ASTM A53 standards.
Yangzhou Chengde founded in 1988, always insist on innovating
and creating excellence. At present, the total assets is 6 billion RMB, the
number of staff is 3000 and cover an area of 2080 acres of the Chengde group.
Chengde group is the first echelon in
national brand on seamless steel pipe and including 4 sections: Jiangsu Chengde
incorporated company, Yangzhou Chengde Steel Pipe Co., ltd, Yangzhou Chengde
Heavy Industry Co., ltd and Taizhou Chengde Steel Pipe Co., ltd.
Chengde have been working on the research.manufacture and sale of seamless pipe about 30 years, and the advantage of core competence is more prominent by integrate in technical.management and market with PCC.
1 The Piercing and rolling technology of Chengde possesses a number of patents in designing and manufacturing the equipment. The production is efficient and flexible, and the quality is stable.
2 The material grade is complete, and the size range is wide (three produce line can manufacture all non-standard sizes). The Minimum Order Quantity (MOQ) as low as ONE piece, and the date of delivery is short with excellent cost performance.
3 The sales and service team is professional and localize.

2, comprehensive mechanical performance is good. Aluminum alloy profiles are widely used in the construction industry in China due to their high strength, good water and airtightness, good heat conduction, attractive appearance, and easy processing. In particular, the advantages of good thermal conductivity have been valued by many radiator manufacturers in recent years.
3, anti-alkaline water corrosion ability, long life. The high-quality copper-aluminum composite heat sink is manufactured using the patented technology of advanced internal flange hydraulic expansion. The precise process parameters can completely eliminate the gap between the copper tube and the aluminum profile tube, and the radiator header and heat pipe Copper, corrosion resistance, no need to do internal anti-corrosion treatment. Therefore, it has good resistance to alkaline water corrosion. Copper-aluminum composite column-wing radiators now being promoted and produced in China, under high-alkalinity water quality, if the annual corrosion rate is analyzed at 0.005mm/year, there can be 50 years of corrosion resistance, leaving sufficient room under this condition. , Can also guarantee the service life of more than 30 years.
4, has a wide range of applicability. The copper-aluminum composite panel type heating radiator is composed of a copper tube and an aluminum profile, and the aluminum profile and the copper tube are tightly combined by high-pressure expansion through a special device. Compact structure, beautiful appearance, easy to clean, light weight, high pressure, good heat dissipation (radiation, convection), durable, suitable for all heating systems.
5. The connection between copper tubes and aluminum wing profiles is prone to problems. At present, the copper pipe and the aluminum profile are closely contacted by the expansion method. Swelling is generally implemented by two methods: mechanical expansion pipe and hydraulic expansion pipe. If the thickness of the copper pipe is uneven and the copper material is not uniform, it may cause the radiator to form between the copper pipe and the aluminum profile after being used for a period of time. A circle of gaps, cooling effect will be discounted.
1, economical. The thermal conductivity of copper and aluminum materials is very good, and the heat dissipation capacity is much higher than other materials. The heat-to-price ratio of copper-aluminum composite radiators is also much higher than that of other materials. Since copper and aluminum are non-ferrous metals, their value increases with time, so copper-aluminum composite radiators also have higher hedge rates.
