25th floor, C3 Building, Wanda Plaza, Kaifu District, Changsha, Hunan Province, China.
Normally the sizes for heat exchanger are 19mm、25mm、32mm、38mm in stock. According to the requirements, the longest length for heat exchanger tube can be 30m, according to different applications, can be used cold drawing (annealing, pickling for soft industrial tube) and cold rolling (wall thickness uniform, a hard state without annealing bright inside and outside, annealing into soft state industrial tube) two processes.
We design and manufacture tubes for the HX market that fully meets the requirements in terms of price, delivery, and specifications.
Our heat exchanger tubes are used for the cooling, heating or re-heating of fluids, gases, or air in a wide range of industries, such as chemical processing, hydrocarbon processing, and oil refining, nuclear power generation and aerospace.
Products Features:
1. Strong corrosion resistance.
2. Strong high-temperature steam erosion resistance
3. Good tube install tech and change tube directly
4. Uniform thickness
5. High heat transfer coefficient
