Problems solved by technology

[0006] Although the performance of the PVC winding pipe can be greatly improved through the above process, in order to meet a certain ring stiffness requirement, the pipe must have a certain thickness, so the material consumption is large and the cost is high

Embodiment 1

[0027] First, the U-PVC material is extruded through an extruder with a cross-section such as Figure 4 , 5 The U-PVC strip 6 shown includes a base plate 61 and an upper cover plate 62, and then the U-PVC strip 6 is heated by a tunnel heater for about 2 minutes, so that the temperature of the U-PVC strip 6 reaches 85° C. And keep the temperature, and the steel belt 7 is input into the winding forming machine for winding to form a U-PVC pipe.

Embodiment 2

[0029] First, the U-PVC material is extruded through an extruder with a cross-section such as Figure 4 , 5 The U-PVC strip 6 shown, including the base plate 61 and the upper cover plate 62, is fed into the winding forming machine together with the steel strip 7 for winding to form a U-PVC pipe, and then the formed U-PVC winding pipe 1 is passed through a tunnel type The heater is heated for about 2 minutes, so that the pipe temperature reaches 75°C.

Embodiment 3

[0031] Firstly, the PVC material is extruded through the extruder with a cross-section such as Figure 4 , 5 The U-PVC strip 6 shown includes a base plate 61 and an upper cover plate 62, and then the U-PVC strip 6 is heated for about 1 minute by a tunnel heater, so that the temperature of the U-PVC strip 6 reaches 55° C. And keep the temperature, and the steel belt 7 is fed into the winding forming machine for winding to form a U-PVC pipe, and then the pipe is heated by the tunnel heater 4 for about 3 minutes, so that the temperature of the pipe reaches 100°C.

[0032] The U-PVC material in the present invention has lower cost and higher hardness than the currently commonly used PE material. In the case of achieving the same performance, the PVC winding pipe with steel belt saves 30% to 60% of PVC material and reduces the cost by 20% to 50% compared with the existing pure PVC winding pipe, which is of great significance for practical application.

Abstract

The invention discloses a U-PVC (Unplasticized Polyvinyl Chloride) steel band spiral pipe and a preparation method thereof. The U-PVC steel band spiral pipe is formed by winding a U-PVC strip and a steel band together. On the basis of the U-PVC spiral pipe, the various advantages of high elastic modulus of steel and extremely low price compared with a plastic material are utilized, and a steel frame is perfectly compounded in the U-PVC spiral pipe, so that rigidity of the pipeline is improved, the cost of the pipeline is greatly reduced, and a new-generation large-aperture plastic steel composite pipe is formed on the basis of original performance of the U-PVC steel band spiral pipe; and compared with the same type of pipeline, the steel band spiral pipe has superior price advantage, and engineering cost of various types of municipal drainage works can be reduced well.

Description

technical field [0001] The invention relates to the field of pipe materials, in particular to a U-PVC steel strip winding pipe and a preparation method thereof. Background technique [0002] PVC winding pipe is suitable for large-scale municipal drainage (sewage) projects and large-scale water conservancy projects. Its production pipe diameter is between Φ300MM-Φ2500MM. PVC winding pipe has the characteristics of acid and alkali corrosion resistance, high ring stiffness, low water resistance coefficient, long service life, strong earthquake resistance, high displacement resistance, and fast construction speed. [0003] PVC material has good physical and chemical properties. Since the early 1980s, the country has vigorously promoted the application of PVC pipes, formulated a series of policies, systems, and standards, and accumulated a lot of experience. Developed to today, it already has perfect product standards, testing method standards and testing methods, construction...
