The primary fields of application include, but are not limited to, the delivery of corrosive media, liquids and gases.
However, because the stainless steel pipe is a hollow pipeline structure, the pressure bearing capacity is not strong, the stainless steel pipe is easy to break under the condition of internally transmitting high-pressure conveying objects or receiving external force, and meanwhile, a plurality of steel pipes are not integrated seamless steel pipes during production, so that the pressure bearing capacity is reduced structurally.
Disclosure of utility model
The utility model aims to overcome the defects and shortcomings of the prior art and provide a stainless steel pipe with high bearing pressure, which is reasonable in design and can solve the defects.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: the novel reinforced plastic pipe comprises an outer pipe, an inner pipe is arranged in the outer pipe, a filling layer is arranged between the outer pipe and the inner pipe, and a reinforcing structure is arranged at the position, close to the inner pipe, in the filling layer.
Preferably, the reinforcing structure comprises a net structure formed by a plurality of annular longitudinal reinforcing ribs and transverse reinforcing ribs, and the inner sides of the net structure are attached to the outer surface of the inner tube.
Preferably, the outer side of the net structure is provided with a spiral reinforcing rib, and the inner side of the spiral reinforcing rib is attached to the outer side of the net structure.
Preferably, the material of the filling layer is polystyrene foam plastic.
Preferably, the outer tube and the inner tube are made of 304 stainless steel.
Preferably, the transverse reinforcing ribs, the longitudinal reinforcing ribs and the spiral reinforcing ribs are made of chromium-molybdenum alloy steel.
After adopting the structure, the utility model has the beneficial effects that:
The device is separated through the inner pipeline and the outer pipeline, the polystyrene material is filled in the inner pipeline, the cavity is prevented from being generated, the sound and heat can be insulated, and when the temperature changes or is pressed, a certain expansion space is provided for the inner pipe, so that the inner pipe is prevented from being expanded by the inner temperature and the outer temperature to cause the outer pipe to be broken.
The device is through double-deck additional strengthening, at first constitutes netted with the strengthening rib, strengthens the compressive capacity of inner tube, and the spiral strengthening rib in outside then can share the pipeline everywhere with local pressure, further strengthens the compressive capacity.
