Problems solved by technology
However, the current composite pipes have more or less disadvantages. For example, the metal composite pipe with composite material inside and metal-plated outside has limited thickness of the metal layer formed by electroplating, so it is easy to be knocked off, and cannot provide such as turning, Various traditional metal processing such as grinding and welding. In addition, although the composite material is hard but brittle, it is easy to be brittle and damaged by impact; another example: the interior is metal and the exterior is metal made of fiber materials by winding Composite pipe, the outer fiber layer cannot be used for various metal processing, and the inner metal pipe is not suitable for transporting corrosive solutions

Embodiment Construction
[0008] Such as figure 1 Shown, the manufacturing method of this metal composite pipe comprises the following steps: (a) select metal pipe, lay fiber layer along pipe wall: select any radius size metal pipe, lay suitable fiber layer along pipe wall inside it; (b) The cover seals the two ends of the metal tube tightly: use the sealing cover to seal the two ends of the metal tube tightly, so that the inside of the metal tube forms a closed space; (c) inject resin and evenly coat the inner wall of the metal tube: connect the metal tube to the axis of the sealing cover One part is fixed on a variable speed motor shaft, and the other side becomes a pivot shaft, so that the metal tube rotates with the variable speed motor at low or high speed, and a thin tube is connected to a sealing cover, and the resin is injected into the metal tube from the thin tube, and the resin will be due to Evenly coated on the inner wall of the metal tube by centrifugal force; (d) Heating the metal tube t...

The invention provides a method for manufacturing a metal composite pipe, which comprises the following steps of: (a) selecting a metal pipe with any radius dimension, and laying a proper fiber layer along a pipe wall in the metal pipe; (b) tightly sealing the two ends of the metal pipe by using sealing covers; (c) rotating the metal pipe at variable speed, simultaneously injecting resin into the pipe, and uniformly coating the resin on the inner wall of the metal pipe under a centrifugal force; (d) heating the metal pipe to cure the resin; and (e) opening the sealing covers to take the metal composite pipe finished product out. The method has the advantages that: the method is simple and convenient to operate; and the obtained composite pipe has light weight, resistance to corrosion, strong bending strength and high resistance to pressure.
Description
technical field [0001] The invention relates to a method for manufacturing a metal composite pipe, in particular to a method for manufacturing a metal composite pipe using centrifugal technology. Background technique [0002] At present, metal composite pipes are widely used, such as water pipes in daily life, automobile condensation pipes, oil pipes, and even cooling water pipes of mechanical equipment. However, the current composite pipes have more or less disadvantages. For example, the metal composite pipe with composite material inside and metal-plated outside has limited thickness of the metal layer formed by electroplating, so it is easy to be knocked off, and cannot provide such as turning, Various traditional metal processing such as grinding and welding. In addition, although the composite material is hard but brittle, it is easy to be brittle and damaged by impact; another example: the interior is metal and the exterior is metal made of fiber materials by winding ...
