SA210 A1 Carbon Steel Seamless Heat Exchanger Rifled Boiler Tube

Application for rifled tube:
The internal thread pipe is also called dry steam pipe, internal rib pipe or internal fin pipe. 

In the central air conditioner, it is mainly used in the dry evaporator. During heat exchange, 

who outside the pipe is cooled by the evaporating and expanding refrigerant in the pipe; 

It is also used in domestic and commercial air conditioning heat exchangers or high heat pipes. 

The internal surface area per unit length of internally threaded pipe is 1.5 ~ 2 times that of ordinary 

smooth copper pipe, and its heat transfer coefficient is 1.5 ~ 2.4 times that of smooth copper pipe of 

the same specification. The flow resistance of the carrier is only increased by 3-5%, which can save

energy by 20-35%, and the weight of the air conditioner suitable for refrigeration is reduced by 10-25%.


The two most critical processes in the production process of  rifled tube:


1. Thread rolling. The design and manufacture of embossing roll is the core technology of 

welding forming. The unscientific design of embossing roll will lead to uneven deformation 

of copper strip, periodic welding defects and shorten the service life of roll.


2. High frequency welding. The linear speed of high-frequency welding is very fast, generally 

the average speed is about 150m / min. such a fast processing speed puts forward higher requirements 

for the accuracy of extrusion and guide rollers. Among the copper tubes used in the world's air conditioning 

and refrigeration industry, > welded tubes account for a small proportion. In addition to the obstacles to the 

traditional understanding of welded pipes, one of the important reasons restricting the promotion of welded 

pipes is the high cost of raw materials (copper strip). At the same time, due to the difficulty of this process

 technology, it is still in the development stage.
