Meeting Point News On the morning of September 22, Jingjiang Development Zone carried out a consultation and discussion activity on "whatever matters", and carried out consultations and discussions on "accelerating the construction of key projects in the development zone". Shen Nansong, deputy secretary of the Jingjiang CPPCC Party Group, some members of the development zone's "negotiable" consultation room, heads of relevant departments of the development zone and enterprise representatives attended the event. The participants visited the production site of new marine material pipes and pipe fittings of Jingjiang Haihong Plastic Technology Co., Ltd. located in the Precision Manufacturing Industrial Park. Haihong Plastic Technology Project is one of the major projects newly started this year. Since the construction started in April, various procedures for approval and construction have been completed, and the main structure of the plant has been basically completed. At present, during the progress of the project, it is found that there is a conflict between the north wall line and the buried power supply pipeline, which affects the construction progress. The delegates went to the enterprise for investigation and research, communicated and discussed with the person in charge of the enterprise, and had a more intuitive and in-depth understanding of the problems existing in the promotion of the project. Afterwards, they expressed their opinions around the existing problems, conducted consultations and discussions, and finally formed 3 solutions for enterprises to choose. Driven by the "one-to-one" nanny project service in the development zone, the company will overcome difficulties as soon as possible and enter the fast lane of construction. It is expected that the project will be completed and put into production within this year, and it will become another example of "started in the same year and put into production in the same year".

Both ends of the vacuum box are open, and flexible gaskets can be installed. The extruded Marine GRE Plastic Pipe is led out of the water tank through the gaskets at both ends. When the Marine PPR Plastic Pipe starts to be pulled into production, the vacuum degree is quickly established, and the vacuum tank with the sizing element should be short. After the vacuum setting tank is set up, a so-called double-chamber vacuum tank is used next to the separate vacuum tank. The vacuum tank is divided into two parts, the vacuum chamber is equipped with a sizing sleeve, which is convenient for the pulling operation of PE100 pipe production. Moreover, when it is necessary to change the vacuum degree to adjust the friction force between the pipeline and the sizing sleeve, it is quite flexible, and the vacuum degree requirements of different cooling stages can be fully considered. For the additional straight-through gasket of the double-chamber vacuum tank, the subsequent vacuum chambers are separated from the sizing chamber, and the vacuum chambers are also isolated from each other. Each chamber has an adjustable exhaust valve, and its vacuum degree can be adjusted separately, and the vacuum degree should be adapted to the requirements of the cooling section. The vacuum chambers are adjustable, but they can share a single vacuum source, and several vacuum units can provide vacuum sources for the sizing chamber and subsequent cooling chamber. Vacuum box gaskets are mostly made of flexible rubber with a hole on it, the diameter of the hole is slightly smaller than the diameter of the extrusion tube to ensure the vacuum tightness of the end of the vacuum box and the different vacuum chambers in the box. In order to completely prevent air leakage, this rubber gasket is usually made quite thick. The gasket must be soft enough to seal tightly around the extruded tube without creating excessive frictional resistance. The lower the temperature of the cool

The choice of materials has always been an important part of marine interior decoration, which determines the user's intuitive feeling and affects the comfort. Therefore, in the purchase of materials, we should not take it lightly. In order to save money, we should choose relatively Inexpensive materials are not desirable. We should choose environmentally friendly and energy-saving materials to give users a better feeling and ensure greater comfort. In fact, the root cause of many problems lies in the purchase of materials. The unqualified materials are bought for the interior of the ship, which leads to the occurrence of later problems. We can only guarantee the quality of the later stage if we choose materials with guaranteed quality. There are many fake materials on the market today. Fake material directly affects the health of users, not just feelings. Therefore, it is necessary to put safety issues first, instead of paying attention to how much money is spent, don't leave yourself a safety hazard, and choose interior materials carefully.

Both ends of the vacuum box are open, and flexible gaskets can be installed, and the extruded glass fiber reinforced plastic pipe is led out of the water tank through the gaskets at both ends. When the glass fiber reinforced plastic pipe starts to be pulled into production, the vacuum degree is quickly established, and the vacuum tank with the sizing element should be short. After the vacuum setting tank is set up, a so-called double-chamber vacuum tank is used next to the separate vacuum tank. The vacuum tank is divided into two parts: First, the vacuum chamber is equipped with a sizing sleeve, which facilitates the pulling operation of plastic pipe production. Moreover, when it is necessary to change the vacuum degree to adjust the friction force between the pipe and the sizing sleeve, it is quite flexible, and the vacuum degree requirements of different cooling stages can be fully considered. For the additional straight-through gasket of the double-chamber vacuum tank, the subsequent vacuum chambers are separated from the sizing chamber, and the vacuum chambers are also isolated from each other. Each chamber has an adjustable exhaust valve, and its vacuum degree can be adjusted separately, and the vacuum degree should be adapted to the requirements of the cooling section.

Before the PE100 plastic pipe is installed, the pipe supports should be embedded, and the installation spacing of the hot and cold water pipe supports should meet the requirements of the specification. It should meet the vertical and horizontal bending of horizontal pipes, the verticality of risers, the installation deviation of rows of pipes and valves, but should not be greater than the allowable pressure of the pipes. After the PE100 plastic pipe is installed, it should be slowly filled with water, and the water tightness should be checked after the water is filled. We use a manual pump to slowly pressurize to the test pressure, hold the pressure for 1 hour, and check that there is no leakage. The pressure drop within 30 minutes is less than 0.05MPa, which is qualified. The PE pipe must be heated when connecting. If the temperature is too low, it will not melt, and burrs will easily occur. Excessive temperature of PE100 plastic pipe will easily lead to resin deterioration and poor connection. Avoid contact with paint, asphalt and other organic substances during storage and installation; do not store in the open air to prevent direct sunlight. When the temperature difference between the construction site and the pipeline storage place is large, it should be placed on the construction site for a period of time to make the temperature close to the construction site temperature. Axial distortion is not allowed when the pipe is installed, and forced correction is not allowed when passing through the wall. When installed in parallel with other metal pipes, there should be a certain protective distance, and should be installed on both sides of the metal pipe, and cannot be rotated for hot-melt splicing and correction. When welding elbows, tees and other pipe fittings, attention should be paid to their direction, and their positions should be marked with auxiliary marks on the straight line direction of the pipe fittings and pipes.

1. Winding butt This street form is to align two tubes and then wind them to the appropriate thickness and width with resin-impregnated reinforcing materials of different scales (glass cloth, felt or felt roving). This kind of joint has good sealing performance and can withstand large internal pressure. It is generally used for the connection of straight pipes, elbows, tees and reducers. 2. Flare socket joint There are many options for this kind of joint. One end of the tube is generally made into a bell-shaped bell mouth, and the next connecting tube is inserted into it, usually sealed with a round (or other shape) rubber gasket. Therefore, this method is sometimes referred to as an "O-ring" connection. 3. The casing connection is a casing with a diameter slightly larger than the pipe diameter, the inner surface is coated with cement, and the outer ends of the two glass fiber reinforced plastic pipes are also coated with cement. Then insert two glass fiber reinforced plastic pipes into the casing, and the cement can be used after curing. 4. Hose joint This joint only covers a rubber sleeve at the opposite ends of the two pipes, and the two ends of the sleeve are clamped with stainless steel belts and fastened with screws. In addition, there are flange joints, adhesive joints, etc., but they are generally not used for underground pipelines.
