pipeline connection technology:
Since the outermost layer of PP-R pipe materials, high-performance fiber composite pipe PP-R pipe fittings available hot-melt socket connection forming a pipeline system. When connected, requiring melt temperature reached to 260 degrees Celsius, pipe and fittings for surface cleaning after a suitable time while heating the fuser and can be plugged low melt connection cost, simple operation, safe and reliable.It can effectively prevent the occurrence of junction leakage.
Pipe and fittings are used for the connection,which are provided by “SAM-UK”. Because different manufacturers may differ from the choice of materials. So it is unable to be guaranteed the quality of the welding connection. Strongly recommended to use special hot-melt welding equipment with temperature control, to prevent welding too hot or too cold, which may affect the quality of welding.

Hydrostatic pressure test
During our decoration, after the completion of welding pipes,we need inspect the quality of pipes, that is we often say the pressure test. The construction of pipes belongs to hidden works in the decoration. Once hidden engineering problems appear, the consequences is incalculable. If the pipe is buried in the ground or floor tiles, the cost of reconstruction will be quite large.
1. Pipes installed, the appearance check is qualified, then the pressure test can be carried out;
2. hot melt or fused connection pipe, the hydrostatic test after 24 hours of the connection;
3. Medium is clean water at room temperature. When in a large system, it can be layered, parted to test the pressure.
Water pressure / method:
1. The hot and cold water connected together by hose. Then hot and cold water forms a ring, pressure testing device connected to any outlet,the pressure pointer is 0. When all the water pipelines installed, the the pressure test could begin. To block all of the plugs and close the water inlet valve manifold before the test.
2. When we do the test, shake the jack lever until the gauge pointer around 0.9-1.0, it is also said that the present pressure is 3 times than the normal water pressure.
3.Keep this pressure value for a certain time, Different time ,the water load time is different, PPR, aluminum PPR, PPR and other steel-plastic pipe welding time is 30 minutes. Aluminum pipe, that’s also the galvanized pips, it needs 4 hours.
PPR pipeline construction safety:
1.PPR pipe cross resistance to ultraviolet radiation, not suitable for outdoor surface mounted installation. If they really need, you need to take shielding measures.
2. PPR pipe’s low temperature impact resistance is poor, it should be vent pipes to prevent freezing, swelling
and crack the pipes in winter.
3. Waterproof toilet area, often using asphalt and other petrochemical substances. When it is doing waterproof needs shelter on pipeline protection.

What Is a Coupling?
A coupling is a device that connects two shafts together. It transmits power from one to the other and is used to join rotating equipment. It can also allow for some degree of misalignment and end movement. It is used in mechanical engineering and manufacturing. To learn more about couplings, read this article.
Mechanical connection between two objectsThe present invention relates to a method and assembly for forming a mechanical connection between two objects. The methods of this invention are suitable for connecting both solid and hollow objects. For example, the method can be used to make mechanical connections between two cylinders. This method is particularly useful for connecting two cylinders that are positioned near each other.
A coupling insert is a part of a vehicle’s drivetrain that absorbs vibrations. These inserts are designed to prevent couplings from moving out of phase. However, the coupling inserts themselves can wear out and need to be replaced. Universal joints are an alternative if the coupling is out of phase by more than one degree. In addition, internal bearings in the coupling need to be lubricated and replaced when they begin to show signs of wear.
Another embodiment of the invention includes a flexible coupling 25 that includes rearwardly-extending lugs that extend toward the coupling member 23. These lugs interdigitate with corresponding lugs on the coupling member 23. They are spaced circumferentially. A first elastic member 28 is interposed between lugs 26 and 27, and is adapted to yield in a counterclockwise direction. As a result, it absorbs torsional vibrations.
Blocks heat transfer
Thermal coupling occurs when a solid block is thermally coupled to the air or fluid passing through it. The amount of heat transferred through a solid block depends on the heat transfer coefficients of the materials. This paper presents a numerical model to understand how heat transfers through different block materials. This work also describes the thermal resistance network for a one-dimensional block.
In some cases, thermal coupling increases the heat transfer mechanism. As illustrated in FIG. 1D, a heatpipe coupler 112 couples two heatpipes 110-1 and 110-2. This configuration allows the pipes to be coupled to the heat source and to the condenser. In addition, the heat pipe couplers may have bellows at the ends to help facilitate linear motion.
Thermal coupling is achieved by ensuring that at least one block is made of a material with a lower thermal expansion coefficient than the annulus. Ideally, the block’s mean thermal expansion coefficient is at least twenty percent lower than the annulus’s mean thermal expansion coefficient. This ensures that the thermal coupling between the two parts is as efficient as possible.
Another type of thermal coupling is achieved by using flexible elements. These are often washers or springs. These components allow the blocks to maintain physical contact with the post 55, which means that the heat transfer is more efficient even at higher temperatures. The flexibility of these elements also makes it possible to choose an element that will not impede assembly.
Protects rotating equipment
A reliable, long-lasting coupling system can reduce the risk of damage to rotating equipment. Designed to protect against torque overload and wear, Voith torque-limiting couplings provide outstanding safety and reliability. As a result, they can deliver maximum performance and minimize equipment downtime. In addition to their long-term benefits, these solutions are ideal for applications where safety and reliability are of paramount importance.
A good coupling provides many advantages, including the ability to transmit power, compensate for axial movement, and absorb shock. It is essential to choose the proper coupling for your application based on the basic conditions of your rotating equipment. For example, if you have two shafts with parallel rotation axes, you should choose a parallel coupling. Otherwise, you should use an angular coupling.
Torque-limiting couplings can also provide protection for rotating equipment by disengaging at a specific torque level. This protects the drive shaft from undergoing catastrophic failure. Torque limiters are particularly helpful for high-value equipment. By preventing catastrophic failure, you can avoid expensive repairs and minimize equipment downtime.
Coupling guards are easy to install and provide effective protection for rotating equipment. These covers are made of sheet metal bent to fit over the shaft. They are durable and easy to remove when necessary. This type of guard can prevent employees from catching their hands, tools, or loose clothing on motor coupling components.
