Concerning the admissible working pressure for fixing material made out of UPVC we refer to the PN-data for the accoutrements (20°C and Water). For different temperatures or mediums please make reference to our product management.
Advantages of the UPVC-System
The material UPVC is characterized by its hardness, dimensional stability and exceptional chemical resistance which result from the interaction of the chlorine atoms in the polymer chain. These characteristics predestine the material UPVC to be used in the production of pipe installations under pressure.
Behaviour of UPVC when used outside
UPVC is weather resistant in middle European climate zones north of the Alps even under the influence of the short wave UV-parts of the sunlight. Nonetheless UPVC loses a little bit of its impact-resistance and therefore it is to your advantage to protect the material by using an Isolation system, a cover or a protective coating in case the product is used under extreme conditions.
Chemical resistance
UPVC has an exceptional chemical resistance, even under the influence of high temperatures or medium concentrations. In comparison to a multitude of dilute or concentrated acids and bases , alkalis and aliphatic compounds, UPVC is rated as resistant. It shows weaknesses when confronted with mediums like ester, ketone, chlorinated hydrocarbons and several other solvents. UPVC is not resistant towards strong oxidants.
The chemical resistance depends on multiple factors, for example the operating temperature, the operating pressure, the concentration and other influences. If you have a special request you can look up the resistance in our resistance list or contact our product management.
Temperature- and pressure range of application
UPVC is usable in a temperature range from 0°C up to 60°C. Temperatures higher than 60°C soften the material relatively fast. Under 0°C the impact-resistance decreases, therefore Akatherm FIP doesn&#;t recommend the use of UPVC in this range of temperature. Concerning the internal pressure capacity of tubes and patterns we refer to the graph under the section Pressure-Temperature-graph. For details regarding the maximum internal pressure capacity of accoutrements please note the additional comments regarding the accoutrement or make reference to our product management.
Electrical property
UPVC is a polar, amorphous thermoplastic with exceptional insulation properties. Because of the possibly resulting static electricity UPVC can&#;t be used in situations where a danger of inflammation or explosion exists.
Low weight
UPVC systems weigh only half in comparison to copper pipe installations and only 1/5 compared to steel pipe installations. This simplifies the handling and new fields of application are possible, in which UPVC can replace metallic systems because of its special characteristics.
As all thermoplastic plastics UPVC has a relatively high thermic coefficient of expansion (0,08 mm/m °C). This fact has to be taken into consideration during the planning of the tube system. There exist several possibilities: Installation of an expansion arc or compensators as well as clamping them at fixed points. In order to do this, sound knowledge of the use of plastic is necessary and we recommend to calculate the planned system with the help of a computer program.
Easy connection
UPVC tube components are connected to each other with adherence. The production of such glued joints requires expertise, which can be acquired in classes held by Akatherm FIP. Concerning the adherence please take into consideration the special guidelines from the adhesive supplier or the published instructions from the KRV (Kunststoffrohrverband e.V.) as well as the corresponding DVS-explanatory leaflets.

Drillers have installed wells using PVC materials for decades. Companies make PVC casing and fittings, and even PVC screen &#; the components of the whole well system. However, advancements over time have meant that PVC in the field today outperforms the materials contractors had access to when HDPE gained widespread use in the s.

Broadly, the &#;recipes&#; companies use to make polyvinyl chloride, better known as PVC, have gone through subtle changes. Contractors may not know from just looking at the finished product, but today&#;s PVCs tend to have more corrosion resistance and durability than earlier generations. That makes it a cost-effective option for well installations, even in harsh environments.
Modern PVC pipe can also provide more flexibility. &#;Flexible&#; PVC is a type of PVC designed to install in wells located in difficult-to-access areas. Flexible PVC is also more resistant to breakage, which can help to prevent leaks in such wells.
Finally, there have been advancements in the methods used to join PVC pipe. Traditional methods of joining PVC pipe, such as solvent cementing, can prove time-consuming for contractors and difficult correctly execute. Newer methods of joining PVC pipe, such as mechanical joining, are faster and easier to do. Mechanical joining also provides a stronger and more reliable joint than traditional methods.

The advantages of using PVC materials in water well construction include:
-
Strength and durability: PVC pipe can withstand the harsh conditions found in many wells. It resists corrosion over time.
-
Environmental friendliness: PVC pipe does not contain any harmful chemicals that can leach into groundwater. PVC materials can also be recycled at the end of their life.
-
Ease of installation: PVC pipe is relatively easy to install, which can save time and money on the well construction project.
-
Cost-effectiveness: PVC materials are a cost-effective choice for water well contractors versus other materials.
-
Long life: PVC materials offer a long life, and they can help to ensure a long and trouble-free life for your well.
Of course, every material can have trade-offs. PVC is no different and contractors should consider these factors in sourcing decisions. PVC is:
-
Strong, but not as strong as steel: PVC may not be a good option for applications with very high water pressure or the potential for a lot of ground movement.
-
Not as chemical resistant: PVC is susceptible to damage from chlorine and ammonia. The former can make PVC brittle and the latter can cause it to swell or deform.
-
Not as easy to repair: A leak in a PVC well may prove more difficult or expensive to repair versus other materials.
PVC pipe, casing and fittings have proven popular for contractors (and their customers) for many years. Their popularity only grows as companies develop advances in their products. Drillers have materials options when it comes to well installation. PVC has improved over time and contractors should give it another look if they haven&#;t in a while. It could be just the thing you need to offer your customers a trouble-free water well that lasts a lifetime.
