Export ASTM A53 API 5L Round Black Seamless Carbon Steel Pipe and Tube

We always focus on product development and technological innovation, and design our solid carbon fiber rods factory, high strength cf kevlar tubing, professional supplier for UAV fiber carbon tube with scientific and stable concepts. We always follow the corporate tenet of keeping faith and justice, serving the society, caring for employees and rewarding shareholders. Our company is equipped with pre-sale technical support and after-sale service, so we have established a good reputation in the industry. Our company continues to meet the needs of domestic and foreign markets.

Xinbo Composite Products Co.,Ltd. can supply round carbon fibre tubes with different carbon modulus .

Standard modulus carbon fibre is the most common grade of carbon fibre used for our round carbon fibre tubes . Standard modulus offer excellent strength and stiffness for the carbon fibre tubes .

It is 1.5 times stiffer than metal , such as aluminum or steel . 

For round carbon fibre tubes , we can reach the following tolerance for outer diameter : 

Natural tube : +/-0.1mm~+/-0.15mm 

Polished tube : +/-0.05mm

We design the carbon fibre lay-up orientations according to per client's requirement and application .

Mostly the round carbon fibre tubes are designed with 0 degree and 90 degree . For special requirement of tube torque , we will design the carbon fibre layers with 30/60 degree or 45 degree . 

Roll wrapped tube is manufactured using multiple layers of carbon fibre prepreg . The number of layers allows us to vary the orientation of the fibers throughout the thickness, creating the best and highest performance according to per client 's requirement.

Round Carbon fibre tubes can be used widely in many areas , such as industrial automation , aerospace , marine spar tube , films & tv equipment , handle tools and sports . 

We are constantly improving our technology to respond more quickly to customer needs for the Export ASTM A53 API 5L Round Black Seamless Carbon Steel Pipe and Tube.
