Hot Dipped Galvanizing Line for Steel Pipe
Hot-dip galvanizing is a popular method for steel product galvanizing, so that zinc can be strongly adhered on pipe outside and inside. After galvanizing, steel pipes are not easy oxidized and can serve longer time.
Production flow chart from black steel pipe to galvanized pipe is as follows :
Each step has a certain machine to match.
Raw material Black steel pipe
Length of Pipe: Usually 6 meters as pipe length, but according to buyer’s special need, we can make it 4 meters to 8 meters as Pipe length.
Galvanizing way: Hot Dipped Galvanizing
Zinc bath heating: Resistance heating or fuel heating
Production Capacity (Example)
The following table shows examples of the production rates for each size of B.S. Medium pipes.
|Norminal Size||Weight of Pipe||Production Capacity|
(1) For good use and maintenance of Kettle, the speed should be set within 8000 kg/hr.
(2) On this case, the tube length is set as 6 meters per pipe.
(3) Above figures are based upon 100% full production.
(4) Dipping time is a big factor when heavy coating is required. But if take a very long time dipping, the production efficiency will be effected. Under the same working condition, zinc coating is depends on dipping time and steel chemical composition.
