PLASTIC PIPING SYSTEMS

OUR PRODUCT RANGE








 

ABS pipe systems for compressed air technology and smoke extraction systems



ABS is a ductile (ductile) material. The fracture behavior is similar to that of soft copper.
Mechanical damage manifests itself in a ductile deformation with a rupture of the material.
Thus, ABS pipe systems is also very well suited for compressed air installations.

UPVC pipe systems - a simple connection



Gluing UPVC pipe systems is the most commonly used joining technique.
This connection technique allows easy installation of new systems and one as well
easy modification of already existing systems.

PVC U TRANSPARENT pipe systems - Connection with a clear view



We carry transparent pipe systems in DIN and INCH (inch) design. In addition to the pipes, we also offer one
extensive large selection of moldings and custom-made products that we also make according to customer requirements.

CPVC pipe systems for high temperatures



CPVC provides good resistance to abrasion and erosion by abrasive media such as abrasive media. Sludges.
Conventional pipe systems made of steel can be quickly destroyed by such media.
The temperature range of PVC-C ranges from 0 ° C to + 95 ° C.

PP - GF pipe systems (polypropylene glass fiber reinforced)



The polypropylene contains 20% polypropylene fiber borosilicate glass type "C", which is chemically resistant.
It has a very good mechanical resistance, a high dimensional stability, is easy to handle and withstands temperatures from -10 ° C to 100 ° C.
Its resistance to UV is improved by the addition of graphite pigments and UV stabilizers.

PP pipe systems



All our pipes and fittings are made of PP-H (polypropylene homopolymer).
The material PP-H has the advantage over other polypropylene materials (PP-R and PP-C) that it has the largest modulus of elasticity
and has the highest yield stress.

PP - R pipe systems



PP-R pipe systems are characterized by high strength under internal pressure and temperature stress, they are corrosion resistant
and chemically very resistant. PP-R pipes and fittings are preferably joined and set by welding
thus a durable, homogeneous material connection.

PE pipe systems



The material PE 100 is considered to be outstandingly resistant to a variety of acids and alkalis.
Polyethylene is relatively resistant to use with hydrocarbons, chlorine and ozone.
However, the chemical resistance depends on many factors, such. As the operating temperature, the operating pressure or other factors.

PVDF pipe systems



PVDF is a material with very high resistance to acids, organic liquids and high UV resistance.
His field of application is chemical and process engineering. Due to its high purity, PVDF is also used for demineralised water and ultrapure water systems
used in the semiconductor industry and photovoltaics.

FRP pipe systems



Glass fibre reinforced plastic, abbreviated as GFRP (in German GFK = Glasfaserverstärkter Kunststoff), also referred to as duroplast, consists of plastic resin and a fibrous reinforcing material. Glass fibres impregnated with an unsaturated polyester resin (UP) or with a vinyl ester resin from the duroplast group, serve as reinforcement material.
In Germany, the vinyl ester resin is identified officially as phenactylate resin and is based for the types e.g. Derakane 411-350 or Distrotone VE 100 on bisphenol A and for the sorts e.g. Derakane 470-300 or DION 9400 on novolac resin

FRP Liner PP, PE and PVDF pipe systems



Kwerk GmbH delivers in addition to UP-GF pipe systems, known as pure GFRP, also UP-GF lining materials for fittings according to pipe type B.

Part of our delivery program are:

- PVC U plasticizer-free polyvinylchloride as per DIN 8061, colour grey
- PVC U plasticizer-free polyvinylchloride as per DIN 8061, colour red
- PVC C chlorienated polyvinylcloride as per DIN 8080
- PE-HD polyethylene of high density as per DIN 8075
- PP polypropylene as per DIN 8078
- PVDF polyvinylidenefluoride

Our UP-GF fittings are free from defects, like air bubbles and cracks. The laminate structure according to DIN 16966 is guaranteed for the entire length.
On principle, other UP-GF structures are available on request. During manufacture of UP-GF, all sealing surfacec and seams are properly laminated

HDPE Drainage pipe systems



Akatherm HDPE is made of High Density Polyethylene which can be welded to reliable, pull tight and leak free joints. A drainage system which can last 50 to 100 years. The high temperature and chemical resistance makes it ideal for drainage in residential housing, commercial kitchens and laundries. It is flexible and tough for installation underground and embedded in concrete. Its closed system is perfect for trade waste applications like industrial and laboratory fluids where system integrity and secure homogeneous connections are critical.
