Description

端口增強環內襯塑膠管承插式金屬管的製作方法 Manufacturing method of socket type metal pipe lined with plastic pipe in port reinforcement ring

本發明涉及一種端口增強環內襯塑膠管承插式金屬管及製作方法。 The invention relates to a socket type metal pipe with a port reinforcement ring lined with a plastic pipe and a manufacturing method.

內襯塑膠管承插式金屬管，因其機械性能好、衛生環保、能耗低、輸水效率高、運行成本低、使用壽命長、環境適用性強等優點，是目前最適合用於自來水輸送的管道。內襯塑膠管承插式金屬管制作完成後管材兩端面的塑膠層與金屬層粘接牢靠，短時間使用過程也相對安全，但當管材使用時間長或長時間堆放於室外，兩端面的金屬層會產生一定的銹蝕，導致管材兩端面的塑膠層與金屬層產生分離，同時在塑膠層收縮產生的拉應力的共同作用時，塑膠層與金屬層分離的面積越來越大，最終可能導致塑膠層有水力的作用下翻邊堵塞管道，影響管道正常供水，塑膠層與金屬層產生分層的位置，水與金屬直接接觸，對水質產生嚴重影響。 Plastic pipe lined with socket type metal pipe, due to its good mechanical properties, sanitation and environmental protection, low energy consumption, high water delivery efficiency, low operating cost, long service life and strong environmental applicability, it is currently the most suitable for tap water transportation Pipeline. After the plastic pipe is lined with the socket type metal pipe, the plastic layer on the two ends of the pipe is firmly bonded to the metal layer, and the short-term use process is relatively safe. However, when the pipe is used for a long time or is stacked outdoors for a long time, the metal on both ends The plastic layer and the metal layer are separated from the two ends of the pipe. At the same time, under the combined action of the tensile stress caused by the shrinkage of the plastic layer, the separation area of the plastic layer and the metal layer becomes larger and larger, which may eventually lead to The plastic layer flanges and blocks the pipeline under the action of hydraulic power, which affects the normal water supply of the pipeline. The position where the plastic layer and the metal layer are stratified, and the direct contact between water and metal has a serious impact on water quality.

基於上述，與現有技術相比，本發明的有益效果是： Based on the above, compared with the prior art, the beneficial effects of the present invention are:

1.內襯塑膠管承插式金屬管一般採用的是熱熔膠的結構解決塑膠管與金屬管粘接的問題，熱熔膠在短時間內能達到塑膠管與金屬管的充分粘接；但是時間長，尤其是受惡劣的環境，如長時間在外日曬雨淋，或極寒或極熱的地區，在輸送介質含酸或鹼或有其他化學腐蝕等情況下，熱熔膠很容易老化，導致塑膠管與金屬管分層，這樣就會堵塞水管，也就造成水的二次污染，採用端口增強環，可以完全解決塑膠管與金屬管分層的問題。 1. The socket type metal tube with plastic tube lined with plastic tube generally adopts the structure of hot melt adhesive to solve the problem of bonding between the plastic tube and the metal tube. The hot melt adhesive can fully bond the plastic tube and the metal tube in a short time; But for a long time, especially in harsh environments, such as long-term exposure to the sun and rain, or extremely cold or extremely hot areas, hot melt adhesives are easily aging when the conveying medium contains acid or alkali or other chemical corrosion. , Resulting in the layering of the plastic pipe and the metal pipe, which will block the water pipe and cause secondary pollution of the water. The use of the port reinforcement ring can completely solve the problem of the layering of the plastic pipe and the metal pipe.

2.內襯塑膠管承插式金屬管，它的連接方式是承插式連接，對管材的承口和插口的圓度要求較高，在端口增加增強環，增加了金屬管承口和插口的強度，能更好的解決金屬管在運輸過程、裝卸過程、安裝過程等因受外力作用的情況下，容易變形，導致安裝難度較大，甚至安裝不了的問題。 2. Socket type metal pipe lined with plastic tube, its connection method is socket connection, which requires higher roundness of the socket and socket of the pipe. A reinforcement ring is added to the port, and the socket and socket of the metal tube are added. The strength of the metal pipe can better solve the problem that the metal pipe is easily deformed due to external forces during transportation, loading and unloading, installation, etc., which makes installation difficult or even impossible to install.

3.增加增強環，可以完全解決塑膠管與金屬管分層的問題，所以可以降低熱熔膠的使用量，同時塑膠管的厚度也能相應減薄，更加節約材料，降低成本，經計算得出節約的材料成本與增加增強環的成本差在60%以上。 3. Adding a reinforcing ring can completely solve the problem of layering between the plastic tube and the metal tube, so it can reduce the amount of hot melt glue used, and the thickness of the plastic tube can be reduced accordingly, saving more materials and reducing costs. It is calculated The difference between the saved material cost and the cost of adding a reinforcing ring is more than 60%.

4.由於內襯塑膠管承插式金屬管，因為承口和插口的金屬壁厚不一致，在管材加熱複合時，承口和插口的溫度很難控制，所以塑膠管與金屬管粘接難度最大的是管材的兩端口，故產品合格率較低，成本非常高，增加增強環能完全解決管材端口未粘接好導致塑膠管與金屬管分層問題，也大大提高了內襯塑膠管承插式金屬管的產品合格率，大大降低了材料成本和生產人工成本。還有就是，內襯塑膠管承插式金屬管的不合格產品很難處理，如要將塑膠與金屬分離成本非常高，得不償失，一般採取兩種方法，一種是將其當廢金屬賣掉，此方法價格極低，成本較高；二種是將其塑膠焚燒，留其金屬管繼續使用，此方法雖然成本較第一種方法低，但是對環境污染較大。所以增加增強環在提高產品合格率的同時還起到了節能降耗、保護環境的作用。 4. Because of the socket-type metal pipe lined with plastic pipe, the metal wall thickness of the socket and socket is inconsistent. When the pipe is heated and compounded, the temperature of the socket and socket is difficult to control, so it is the most difficult to bond the plastic pipe to the metal pipe. It is the two ports of the pipe, so the product qualification rate is low, and the cost is very high. Adding a reinforcing ring can completely solve the problem of plastic pipe and metal pipe layering caused by the unbonded pipe port, and greatly improve the socket of the lined plastic pipe. The product qualification rate of the metal pipe greatly reduces the material cost and production labor cost. In addition, unqualified products with socket-type metal pipes lined with plastic pipes are difficult to deal with. If the cost of separating plastic from metal is very high and the gain is not worth the loss, two methods are generally adopted. One is to sell it as scrap metal. The price of this method is extremely low and the cost is high; the second method is to incinerate the plastic and keep the metal pipe for use. Although the cost is lower than that of the first method, this method has greater environmental pollution. Therefore, adding a reinforced ring not only improves the product qualification rate, but also plays a role in energy saving and consumption reduction and environmental protection.

5.本發明採用對內襯塑膠管承插式金屬管兩端口安裝增強環的技術方案，防止了內襯塑膠管承插式金屬管內外層產生分層，有效保持了內襯塑膠管承插式金屬管結構的穩固性和完整性。 5. The present invention adopts the technical solution of installing reinforcement rings on the two ports of the socket type metal pipe lined with plastic pipe, which prevents the inner and outer layers of the socket type metal pipe lined with plastic pipe from delamination, and effectively maintains the socket of the lined plastic pipe The stability and integrity of the metal pipe structure.

6.本發明通過控制內襯塑膠管承插式金屬管外徑變形量來控制增強環脹環變形量，尤其是先通過控制擴徑設備或脹管設 備壓力自動定位計算出內襯塑膠管承插式金屬管內徑或外徑，再通過脹管設備或擴徑設備的脹管模具外徑增大至所設定值(即需增加內襯塑膠管承插式金屬管本體的變形量)而達到不銹鋼增強環的變形量的技術方案，既保證了增強環安裝堅固、牢靠，又防止了內襯塑膠管承插式金屬管變形過大導致的管材開裂及管材安裝困難問題，同時解決了脹管設備或擴徑設備壓力大小無法控制壁厚大小不一、管材不圓的內襯塑膠管承插式金屬管脹環變形量大小問題。 6. The present invention controls the deformation of the reinforced ring expansion ring by controlling the deformation of the outer diameter of the socket type metal pipe lined with a plastic pipe, especially by first controlling the diameter expansion equipment or the expansion device The prepared pressure is automatically positioned to calculate the inner diameter or outer diameter of the socket-type metal pipe of the inner plastic pipe, and then the outer diameter of the expanding pipe mold of the pipe expanding device or the expanding device is increased to the set value (that is, the inner plastic pipe needs to be added The technical solution to achieve the deformation of the stainless steel reinforcement ring not only ensures the installation of the reinforcement ring is firm and reliable, but also prevents the pipe from cracking caused by the excessive deformation of the socket type metal pipe with the inner plastic pipe. It also solves the problem that the pressure of the expansion equipment or the expansion equipment cannot be controlled by the pressure of the expansion equipment or the expansion equipment. The wall thickness is different, and the pipe is lined with plastic pipe socket type metal pipe expansion ring deformation.

7.本發明採用增強環脹環時金屬管外徑擴大1-2mm，等脹管設備或擴徑設備停止工作時，金屬管會迅速回縮，而增強環脹接在塑膠管表層，且塑膠管產生形變0.1mm-1mm，這樣增強環利用壓應力牢牢支撐塑膠管端口，從而解決塑膠管與金屬管分層的問題。 7. The outer diameter of the metal tube is expanded by 1-2mm when the reinforced ring is used in the present invention. When the tube expanding device or the diameter expanding device stops working, the metal tube will quickly retract, and the reinforced ring expands on the surface of the plastic tube, and the plastic The pipe is deformed by 0.1mm-1mm, so that the reinforcement ring uses the compressive stress to firmly support the plastic pipe port, thereby solving the problem of the layering of the plastic pipe and the metal pipe.

8.本發明採用機械手放環，平齊機將增強環與內襯塑膠管承插式金屬管端口平齊的技術方案，生產效率高，所加工產品品質穩定可靠。 8. The present invention adopts the technical scheme that the manipulator puts the ring and the leveling machine aligns the reinforcing ring with the socket type metal pipe port of the lined plastic pipe, which has high production efficiency and stable and reliable quality of processed products.

9.本發明採用富鋅漆對安裝好增強環進行防腐處理的技術方案，可提高內襯塑膠管承插式金屬管的內防腐性能，延長內襯塑膠管承插式金屬管的使用壽命，使增強環的效果進一步顯著。 9. The present invention adopts the zinc-rich paint to carry out the anti-corrosion treatment of the installed reinforcing ring, which can improve the internal anti-corrosion performance of the socket type metal pipe lined with plastic pipe and prolong the service life of the socket type metal pipe lined with the plastic pipe. Make the effect of the reinforcement ring more significant.
