Advantages
|
Disadvantages
|
|
Welded Tube/Pipe
(Fit for mass production)
|
-
Uniform wall thickness, internal surface is in good quality
-
High production efficiency and low costs
-
Easy to manufacture larger diameter tubes/pipes
-
Short production term
-
Easy to control prodcts quality
|
-
Poor flexibility, not available to produce various of specifications but small quantity products
-
Welding seam is hard and require skilled person and easy to cause troubles
-
Difficult to clean the welding line
-
Difficult to control ovality
-
Strict dimension requirements for tantalum strips
|
|
Seamless Tube/Pipe
(Fit for customized production)
|
-
Available to produce small specification tubes/pipes and capillary tube/pipe
-
Excellent flexibility, available to produce various of specifications but small quantity products
-
Uniform performance of the whole tube/pipe
|
-
Uniformity of the wall thickness is difficult to control
-
Longer productivity term but lower finished products rate
-
Complexed equipment requires high investment capital
-
Hard to product large diameter tube/pipe
