1. The carbon fiber tube memory ability is very good, will restore the original state after bending, sporting goods are widely used.
2. If the impact force is enough, the carbon fiber will be torn apart, it is used in car shell, torn crash energy absorption and protection of the car. So, you need to tube, depends on the intensity of demand to design.

3. The hole in the carbon fiber tube won't appear problem, once have the damage, will be scrapped, but the design strength, there is no these problems within the required range.
4. Equal strength requirement, the carbon fiber tube wall will be thicker, but lighter than steel.(density is small, and steel)

In the form of welded steel scaffolding tube according to the weld seam welded scaffolding tube and spiral welded scaffolding tube.

The strength of the spiral welded scaffolding tube is generally higher than straight seam welded scaffolding tube, use a narrow billet production of larger diameter welded scaffolding tube, you can also use the same width of billet in the production of different scaffolding tube diameter welded scaffolding tube. But compared with the same length of straight seam scaffolding tube, weld length by 30 ~ 100%, and the production speed is low. As a result, a small diameter welded scaffolding tube are mostly with straight seam welding, large diameter welded scaffolding tube for the most part adopts spiral welded.

General low-pressure fluid conveying spiral seam submerged arc welding steel scaffolding tube (SY5037-83) is a hot rolled steel coil tube billet, often temperature spiral forming, the double automatic submerged arc welding or one side welding into legal system for water, gas, air and steam general low-pressure fluid conveying with submerged arc welding steel scaffolding tube.
