Q&E PPSU Fittings for Pexa Systems

PPSU fittings are made from special polymer –  Polyphenylsulfone (PPSU).
Using PPSU pipe fittings to connect with PEX pipe are characterized by high impact strength, high temperature resistance(up to +170 ° C) and exposure to aggressive environments. Like other plastic products, PPSU is not subject to corrosion. PPSU compounds are also UV resistant and sediments of mineral substances dissolved in water.
Various types of PPSU products are widely used in food processing equipment(dairy machines, filtration panels, heat exchangers) and for medical components products subject to repeated cleaning and sterilization: attachments for endoscopic holders surgical devices, handles for dental and surgical instruments.
Such modern plastics are successfully replacing metals, providing significant economic- the range of traditional materials, energy resources, labor costs and operating costs. Our PPSU pipe fittings are designed for using in cold and hot water supply, radiator and underfloor heating systems.

Specifications of PPSU fittings:

• maximum allowable working pressure: 10 bar;
• test pressure is 16 bar;
• maximum permissible temperature of the transported medium: 95 ° С;
• service life: 50 years (subject to the temperature conditions given in GOST 32415-2013);
• melting point +170 ° C;
• approved for use in drinking water supply systems;

  • very good sound and electrical insulation of installation thanks to using PPSU fittings
  • significant savings of heat, PPSU material is characterized by greater thermal resistance as compared to brass so fittings give less heat back
  • durability and high quality  of PPSU fittings of KAN-therm system confirmed by Polish certificates  and examinations in the reputed European Institute KIWA
  • 100% reproducibility of product, production technology of PPSU fittings practically excludes any latent defects

FAQ

Q1. What material of pipe are you specialized in?

A: We manufacture PE-Xa,  PPR,  PE-RT, PEX Aluminum composite pipes and fittings.

Q2. Do you produce PVC pipes and fittings?

A:Sorry, dear friend. We are more professional PE and PPR pipe and fittings, which are more suitable for drinking water as they are more hygienic than PVC material. 

Q3. Please tell me your largest outer diameter for pipes.

A: We can produce 8mm– 110mm diameter (PE pipe).

Q4. The price of your products is higher than others.

A: We can’t promise you the best price, but we can promise you the best quality. We import raw material from famous companies such as Borstar, LG Chemical, Chervrom, Hyosung, Lydellbasell, Sinopec.

Q5. For pipe fittings, what do you do mainly?

A: For fittings, coupling (socket), elbows, tee, reducer, union, valve, cap and copper insert fittings are our main products.

Q6: Can you provide us some samples for testing?

A: Of course, my friend. For small amount of samples, we can provide you for free.

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.
