1. Description for Carbon Fiber Tube


Our composite tubing, and in particularly our carbon fibre tubes, have significant advantages over most materials in terms of mechanical properties. The table opposite shows comparisons with other common materials.


CF Fabric

CF Uni-Directional



Density (g/cc)





Youngs Modulus 0°(GPa)





Youngs Modulus 90°(GPa)





Ult. tensile Strength 0°(MPa)





Ult. comp Strength 0°(MPa)





Ult. tensile Strength 90°(MPa)





Ult. comp Strength 90°(MPa)






As can be seen, carbon fibre has excellent strength and low density. If these two factors are considered together, therefore looking at ‘specific strength’, then the benefits of carbon fibre look even more impressive. This is highlighted in the graph opposite.


 2.Production process


When the laminate has been designed and verified by our engineers the individual patterns are fed to our 5 metre long CNC cutting table which cuts out each pattern precisely. The materials we use are cloths which already have the resin matrix impregnated in to them, known as pre-pregs.


Next, these prepreg layers are wrapped around the male tooling (mandrels) which determine the Inside Diameter (ID) of the tube. These patterns are wrapped in an exact sequence on our machine driven rolling table to ensure consistency and accuracy of the lay-up.


The tubes are then subjected to a high temperature curing cycle under pressure in our electronically controlled ovens and finally removed from the tooling using a hydraulically powered puller mechanism.


Once complete, the raw blank is then ready to be machined and finished in line with the design specification.

3. Features for Carbon Fiber Tube 


With over 60 years of collective marine experience we have a significant insight to this industry. This, coupled with our vast knowledge of composites, is invaluable given the diverse nature of composite marine applications.


We produce tubing for all types of marine applications, from small dinghy tiller extensions, paddle shafts, and spars up to one-off tubing for large yacht masts.



The flexibility of our manufacturing process is one of our distinctive qualities in this area:


  • Able to make tapered tubing which is ideally suited for mast applications.

  • We can make oval tubing often sought after for masts or booms requiring differential properties in different axes.

  • Tubes are made with epoxy resin systems which have virtually zero water absorption making them more suitable for marine based use than lower quality tubing made with vinylester or polyester resin systems.

  • We have in-house paint facilities and are able to finish tubes with UV stable paint systems, protecting the tubing against inevitable long exposure to the elements.

Q:What do you mean by pipe fittings 3/4?
Supplement:1 inches =25.4 mm, =8 British points, 1/2 is four points (4 British points), DN diameter 15mm, 3/4 is six points (6 points), DN20mm.
Q:How many types of hydraulic connections?
Classification of pipe joints:High pressure ball valve, quick joint, clamp sleeve pipe joint, welded pipe joint, high pressure hose. Transition type pipe joint, clamp type pipe joint, three type pipe joint, non-standard pipe joint, flared pipe joint, right angle pipe joint, rotary pipe joint, quick joint, stainless steel pipe joint and copper joint.
Q:Is the thread at the two ends of the card sleeve the same?
InequableThe card sleeve is divided into two types: a single card sleeve and a double clamp sleeveThe sleeve end thread single card is generally metric thread, 6mm or 1/4 "card sleeve thread is M12*1.5."G1/4 is pipe thread with fixed thread, outer diameter and pitchDouble card for UNF fine thread (also have metric teeth, but already very little), and G1/4 internal thread is even more not matching
Q:Consult the problem of the pressure at the entrance and exit of the pipe joint
The oil outlet is 2MPa, too,The relation between the pressure at the outlet and what you call the inlet pressure is as follows:
Q:What kind of tubing connections do you have?.
Pipe joint is detachable between the tubing and tubing, tubing and hydraulic components of the connection, it should satisfy the convenient assembly and disassembly, reliable connection, reliable sealing, small size, large capacity oil, small pressure loss, good processing etc.
Q:How to identify the pipe joint thread quickly and accurately?
3 can also use a known threaded joint, if you want to identify the male pipe joint with a known female connector; if you want to identify the female pipe joint with the known male pipe joint, try to see if it can easily connect
Q:The hydraulic pipe fittings how to distinguish the British, American, metric!
Metric threads are represented by pitch, and American and English threads are expressed in thread per inch;Metric thread is 60 degrees equilateral tooth type, thread is isosceles 55 degree tooth type, thread is isosceles 60 degree tooth type;
Q:Air conditioning outdoor units, pipe joints, frosting, or even icing
As long as the counterclockwise rotation, with the starting force of about 10% of the screw can not move, it means that it has been opened to the maximum degree.
Q:Type parameter of pipe joint

Q:What is the function of the pipe joint?
This is a general term for connections that can be disassembled in a fluid path. It mainly includes welding type, clamping sleeve type and flaring type
