The best way for element manufacturers to control the tube stock and minimize stock costs, is to produce the tubes themselves. (It is also wise to minimize the number of tube sizes.) GRANLUND offers tube welding mills intended for continuous welding of thin walled tubes for various applications.
The quality of the strip is very important
(cleanliness, burrs and dimension tolerances).
