Forming method of bamboo winding reducer pipe and reducer pipe formed by forming method

Abstract

The invention discloses a forming method of a bamboo winding reducer pipe and the reducer pipe formed by the forming method, and belongs to the technical field of pipeline connection. A sealing section is arranged on the periphery of one end of a tubular pipeline body in the circumferential direction, a plurality of unit layers and an external connecting layer located on the outermost side are sequentially arranged on one side, deviating from the end face of a matched connecting end, of the sealing section to form a different diameter portion which is connected with the outer periphery of thematched connecting end, and the outer diameter of an outer pipeline is larger than that of the outer diameter of the pipeline body, so that the matching communication between the pipeline body and theouter pipeline with the large inner diameter is achieved. According to the forming method of the bamboo winding reducer pipe and the reducer pipe formed by the forming method, the method is simple, the structure is simple and convenient, the pipeline body is effectively matched and connected with the outer pipeline with the large inner diameter, the application of a special joint is reduced, thecost for connecting two different-diameter pipelines is greatly reduced, the construction process is simplified, the construction strength is reduced, the sealing performance and the stability of pipeline connection are ensured, and the method has good application and popularization values.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection, and in particular relates to a forming method of a bamboo-wound variable-diameter pipe and a variable-diameter pipe formed by using the method. Background technique [0002] In many technical fields, the application of pipelines is very extensive, and its application forms are also very diverse. Traditional pipes can be divided into metal pipes, plastic pipes, cement pipes and glass pipes due to their different materials. , high temperature resistance, easy to process, but often heavy, easy to corrode, difficult to construct and average service life; plastic pipes are often light in weight, corrosion resistant, easy to process, but poor in temperature resistance and pressure bearing capacity, and small in rigidity And it is easy to age and has a short service life; the strength of glass pipes is often high, corrosion-resistant, and the friction coefficient is small, but in the case o...

Traditional pipes can be divided into metal pipes, plastic pipes, cement pipes and glass pipes due to their different materials. , high temperature resistance, easy to process, but often heavy, easy to corrode, difficult to construct and average service life; plastic pipes are often light in weight, corrosion resistant, easy to process, but poor in temperature resistance and pressure bearing capacity, and small in rigidity And it is easy to age and has a short service life; the strength of glass pipes is often high, corrosion-resistant, and the friction coefficient is small, but in the case of large diameters, the pressure bearing capacity is limited, glass fibers may be precipitated after long-term use, and it is not conducive to recycling, etc. wait

[0004] During the use of bamboo winding pipes, pipes of the same diameter are usually connected to each other, and the diameter of the pipes is generally a standard size, so that the connection of the pipes is highly sealed; however, in the actual application process, often In the case of butt jointing of two pipes with different diameters, that is, the butt joint of different diameter pipes, in the prior art, the processing method for the butt joint of different diameter pipes is usually realized by using a special joint, and the two ends of the special joint are often provided with different The interface of the pipe diameter corresponds to the connection of pipes of different diameters. Although this processing method can realize the butt joint of different diameter pipes to a certain extent, the special joint in the above processing method needs to be customized according to the actual situation. The preparation process Complexity and high cost of use indirectly increase the application cost of bamboo winding pipes, and the use of special joints will increase the number of connection points for pipe connections, which will not only complicate the construction process and increase the construction strength, but also easily cause connection seals Poor performance, resulting in hidden dangers of leakage, thus making the application of bamboo winding pipes have certain limitations
