Advantages and disadvantages of seamless pipes and welded pipes.

Advantages

Disadvantages

Description

Welded Tubes

1: Uniform wall thickness and good inner surface quality

2: High production efficiency. Low cost

3: Easy to produce large diameter pipes

4: Short production cycle

5: Product quality is easy to control

1: Poor flexibility, not suitable for the production of many specifications and small quantities of products

2: Weld seams are often the weak link

3: Weld cleaning is more difficult

4: Ellipticity is not easy to control

5: High dimensional accuracy required for the strip used

Generally suitable for the production of large quantities of products

Seamless tube

1: Can produce small size pipe and capillary material

2: Good flexibility, suitable for the production of small batches and many specifications of products.

3:Uniform performance of all parts of the pipe

1:Uniformity of wall thickness is difficult to control

2:Long production cycle, low rate of finished product

3:Complex equipment, large investment

4:Difficult to produce large diameter pipes

Generally suitable for the production of small batches of products with many specifications
