ALMATERHM Pipes & Fittings is a subsidiary company of almanit sanitary gmbh in Hamburg - Germany. We are specialized in supplying piping products and fittings for plastic piping systems of pressure and hot water (heating) distribution. Our main products are PP-R Fittings, PP-R Pipes, PP-R Stabi pipes with aluminum layer and PP-R Fiberglass composite pipes.
Our production and inspection is effected strictly according to Germany and European standards. For our PPR system production, we only use the highest-quality materials, granulates with high molecular weight and highly heat stabilized; Colour: gray/green. The raw material used is in compliance with the recommendations of the German Federal Public Health Department (BGA).
ALMATHERM pipes and fittings are in accordance to DVGW test standards, the German Technical and Scientific Association for Gas and Water.
Problematic spots like plastic-metal transitions are handles without compromise - we use metal components manufactured from highest –quality brass tubes and rods from Germany. Our production process is fully automated, and our technologies are improved constantly.
Nobody understands plumbing distributions better than those who work with them every day - the plumbers. We know that they appreciate it when their job is made easy and they don’t have to deal with complaints.

4.Exceptionally long service life while preserving high utility value
5.Trouble - free operations with less noise
6.Less friction losses than with traditional materials
7.Less weight than with traditional materials
8.Quick, easy and clean installation works
9.Resistance in aggressive environments.
ENVIRONMENTAL ASPECTS
Fully recyclable product; neither toxic nor otherwise harmful substances are used in its manufacture and/or application.
INTENDED USE
For interior hot and cold water distribution systems in buildings and floor & central heating systems:
PN 10 - cold water distribution and floor heating systems
PN 16 - higher pressure cold water distribution and DHW systems at lower pressures
PN 20 - hot water distribution systems, central heating
TECHNICAL SPECIFICATIONS
Material - statistical polypropylene copolymer (random - copolymer) for injection moulding and extrusion processes with excellent welding ability; nickel - plated brass fittings
Manufacturing process - pipes are produced by extrusion, while fittings by injection moulding
Shapes - pipe lengths or coils
Assembly/fixing - the product range covers all needs for interior water distribution systems and heating system routes
Transitions for other pipe materials - implemented by threaded connections (i.e. by combined couplings) or flange connections
Coupling - standard method is poly fusion welding or by electro fitting
Surface finish –Elements are in gray and green colour without any finish, Separate metal elements - brass, alternatively nickel plated, Black identification printing on the surface.
PHYSIC - CHEMICAL PROPERTIES
Specific weight - 0.9 kg/m3
Thermal expansion coefficient - for PPR pipes 0.15mm/Mk
Thermal conductivity 0.22 W/mK, fire rating - Class C3
Resistance against chemicals - PPR piping systems are intended mainly for water distribution (drinking, cold, hot, irrigation, etc.) - it is also possible to use the system for other media, in which case their concrete use is governed by DIN 8078 Bb 1 - possible to consult the manufacturer.
QUALITY CONSIDERATIONS
PPR pipes and fittings are available in the market at different price levels. Through the naked eye, customers cannot verify quality aspects which would help them to justify difference in price.
The deciding factor in the PPR pipes and fittings manufacturing process is the use of correct / pure raw materials. To reduce production costs, some manufacturers tend to:
+ use-B and/or-H granulates as alternative to original PPR Type 3 granulates.
+ use PE blends (obsolete generation and second generation)alternative to original PPR Type 3 granulates.
+ a high percentage of recycling material with original granulates.
Products manufactured by using non-proper and/or low quality raw material has a great effect on quality of end products:
+ pipes and pipe fittings are no longer consisting with PPR material properties and characteristics.
+ a direct impact on the welding quality (example: melting point of material is 140°C, that of-B material is160°C) - welding conditions become different that the welding quality is easy to grasp. This is due to the fact that kinds of crystalline materials used in the PP blend mix have varying melting degrees.
+ the rate is different in the welding process due to the different shrinkage rates which leads to stress concentration.
+ when the raw material is mixed with a number of recycling industrial waste plastic granulates, pipes and fittings produced could bend thus not suitable for-term use transport drinking water. This seriously damage people's health.
+ and black smoke appears during the welding process.
+ the span of pipes fittings is rather short. Leakage problems will start within first months of regular function. The repair and replacement costs in case of occupied residential units will be much higher.
The production machines play also an important role in securing a quality product. Low quality suppliers tend to use cheap equipment for their manufacturing process. For example: are produced with an uneven wall thickness all throughout the pipe. This will have a great impact on quality of the pipe and it chemical / thermal characteristics.
