Product Description

Reducer Coupling of Sliding Compression Type Fittings for PEX-AL-PEX Brass Components/Fittings

CW617N Brass Fitting Reducing Coupling S20-16


This system will let you combine our range of multilayer pipes (PEX + Aluminium) of the latest generation with all CZPT Brass fittings, normally used for the connection of PEX pipes.

HEWAI multilayer pipes consist of a cross-linked polyethylene (PEX) pipe, manufactured according to the European Regulation EN 15875 (16 x 2,3; 20 x 2,7; etc.), to which an aluminium layer butt welded by laser and an outside layer of high density polyethylene are added to serve as a protection against mechanic wear and tear as well as corrosion.

HEWAI manufactures the multilayer pipes using the most up-to-date Swiss technology for the production of multilayer pipes, technology that comes from the optical fibre industry.

Complex extrusion lines of more than 100 CZPT long are composed of 4 plastic extruders, a sophisticated conformation equipment and the aluminium welding system. We should highlight that CZPT pipes are manufactured using a butt welding system that provides the pipe with superior technical features (resistance to pressure and bending possibilities) compared with other technologies where aluminium is overlapped and simply welded by ultrasound.

The CZPT piping system will let you benefit from the generic advantages of the multilayer pipes with the specific advantages of the CZPT multilayer pipes and those of the range of CZPT fittings.

Programming With Couplings

A coupling is a mechanical device that connects two shafts together and transmits power. Its purpose is to join rotating equipment and allows some degree of end-movement or misalignment. There are many different types of couplings. It’s important to choose the right one for your application.

Mechanical connection between two shafts

There are many ways to achieve mechanical connection between two shafts, including the use of a coupling. One common type is the beam coupling, which is also known as a helical coupling. It is used for transmission of torque between two shafts. This type of connection accommodates axial, parallel and angular misalignments.
The hubs and shafts of a worm gear are connected together by a coupling. This mechanical connection allows one shaft to turn another without causing a mechanical failure. This type of coupling is made from sliding or rubbing parts to transfer torque. However, the coupling is not designed to withstand jerks, so it isn’t suitable for high-speed applications.
The use of a coupling is common in machinery and equipment. It helps transmit power from one drive shaft to the other, while adding mechanical flexibility. It is also useful for reducing the impact and vibration caused by misalignment. It also protects the drive shaft components from wear and tear.
A double-hook coupling can be used to provide a uniform angular velocity at the driven shaft. Another example is a double-jointed coupling. A double-jointed coupling can be used to connect shafts that are not directly intersecting. The double-jointed yoke can be used for the same purpose.
A shaft coupling is a device that maintains a strong mechanical connection between two shafts. It transfers motion from one shaft to another, at all loads and misalignments. Unlike a conventional linkage, a shaft coupling isn’t designed to allow relative motion between the two shafts. Couplings often serve several purposes in a machine, but their primary use is torque and power transmission.

Functions that control the flow of another function

One of the simplest programming constructs is a function that controls the flow of another function. A function can take an argument and return a different value, but it must be ready to return before it can pass that value to another function. To do this, you can use the goto statement and the if statement. Another way to control flow is to use a conditional statement.

Criteria for selecting a coupling

There are several important factors to consider when choosing the right coupling. One of the most important factors is coupling stiffness, which depends on the material used and the shape. The stiffness of a coupling determines its ability to resist elastic deformation. A stiff coupling is desirable for certain types of applications, but it’s undesirable for others. Stiffness can reduce the performance of a system if there’s too much inertia. To avoid this, ensure that the coupling you choose is within the recommended limits.
The size of a coupling is also important. Different coupling types can accommodate different shaft sizes and shapes. Some couplings have special features, such as braking and shear pin protection. When choosing a coupling, you should also consider the type of driven equipment. If you need to connect a high-torque motor, for example, you’ll want to choose a gear coupling. Likewise, a high-speed machine may require a disc coupling.
Another factor to consider when selecting a coupling is the torque rating. Despite its importance, it’s often underestimated. The torque rating is defined as the torque of the coupling divided by its OD. In some cases, torque may fluctuate during a cycle, requiring a coupling with a higher torque rating.
Torsionally flexible couplings are also important to consider. Their design should be able to withstand the torque required during operation, as well as the required speed. The coupling should also have a high degree of torsional stiffness, as well as damping. Furthermore, a damping coupling can reduce the energy wasted through vibration.
The sizing of a coupling is also determined by the torque. Many engineers use torque to select the correct coupling size, but they also take into consideration torsional flexibility and torsional stiffness. For example, a shaft may be able to handle large torque without damaging the coupling, while a disk may be unable to handle large amounts of torque.
Besides torque, another important consideration in coupling selection is the cost. While a coupling may be cheaper, it may be less reliable or easier to maintain. Couplings that are difficult to service may not last as long. They may also require frequent maintenance. If that’s the case, consider purchasing a coupling with a low service factor.
There are many different types of couplings. Some require additional lubrication throughout their lifetime, while others are 100% lubrication-free. An example of a 100% lubrication-free coupling is the RBI flexible coupling from CZPT. This type of coupling can significantly reduce your total cost of ownership.
In addition to the above-mentioned benefits, elastomeric couplings are low-cost and need little maintenance. While they are often cheaper than metallic couplings, they also have excellent shock absorption and vibration dampening properties. However, they are susceptible to high temperatures. Also, they are difficult to balance as an assembly, and have limited overload torque capacity.
