Uponor Flexible Pre-insulated Pipes

Although excellent materials and perfect processing are essential for making a high-quality product, a product will only really prove its worth in practice in a well-engineered system. That means our products are all exactly compatible with one another and can therefore be installed easily and correctly under the often difficult conditions on the daily construction site. Uponor Ecoflex proves its fit-for-purpose property not only by its flexibility. At the end of any pipe system, the lever arm, of course, becomes shorter and shorter. This is a system whereby only a minimum of strength is required for even small bending radii. House lead-ins, installations around obstacles, or pipe branches are easy to handle and allow installations to be carried out swiftly and on schedule. We find the simplest solution the best. And we attach great value to the fact that our system components can be installed without the use of any special tools.

Every single meter of Uponor Ecoflex pipe is backed by 20 years of experience. Quality and suitability for use are, and always were, at the foreground of our developments for a variety of system solutions. We take in product details such as the geometry of the outside jacket, the type and design of the insulation, the material for the medium pipe, i.e. the real „insides“ of an Uponor pipe into consideration. And not to be forgotten, the pipe’s most special, visible feature – its flexibility.

Polyethylene grades such as HDPE or PE-Xa have the basic chemical and physical properties to lend the pipes the best pre-requisites for us in supply lines engineering.

The high-grade plastic of the medium pipe prevents particle deposits and corrosion and features a tremendously long service life coupled with highest temperature stability (PE-Xa) and crack resistance. The use of monitoring elements in accordance with EN 14119 is therefore not required. The fact that we set quality standards for all of our products which are far higher than the usual requirements, ensures maximum project safety and service life.

The article presents the range of products: Uponor Supra flexible pre-insulated pipes, Uponor Aqua Single/Aqua Twin flexible pre-insulated pipes, Uponor Single/Thermo Twin/Thermo Mini flexible pre-insulated pipes, Uponor Quattro flexible pre-insulated pipes.

Thermal Insulation to Prevent Legionellae in Drinking Water Systems

Armacell insulation materials protect hot and cold pipes against inadmissible decreases and increases in temperature

Legionellosis, also known as Legionnaires’ disease, continues to cause deaths. According to estimates made by the Robert Koch Institute, every year in Germany alone around 10.000 people contract this form of pneumonia, which is transmitted by germs in water. Errors made when designing and installing plumb­ing systems can lead to a harmful multiplication of legionellae in drinking water. One of the most important preventive measures is to insulate hot and cold drinking water pipes properly with suitable insulation materials.

There are a number of operating, constructional and process-related measures for avoiding a harmful multiplication of legionellae in drinking water. Where possible a combina­tion of these should be implemented. Apart from ensuring that the water circulates continu­ously in the pipework, it is also necessary to prevent inadmissible temperature decreases in hot drinking water pipes and temperature increases in cold drinking water pipes.

Because of the risk of condensation forming, closed-cell insulation materials with a high resistance to water vapour transmission are recommended for the insulation of cold drinking water pipes. Pipes should be laid with sufficient clearance to heat sources, such as hot pipes, and insulated. If there is an increased risk of legionellae in plumbing installations, because hot and cold pipes are laid in one duct or wall slot or there is no regular circulation in the pipes, for example, it is essential that the pipes are adequately insulated. Here Armacell recommends using what is known as 100 % insulation, i.e. an insulation thickness which roughly corresponds to the outer pipe diameter. When insulating hot drinking water pipes, this not only serves to prevent legionellae, but also protects the pipes against unnecessary energy losses.

The Armacell products SH/Armaflex and Tubolit are highly suitable for insulating hot and cold water pipes. The insulation materials were developed especially for use in heating and plumbing applications. Due to their excellent technical properties, the insulation materi­als reliably prevent the temperature of the pipes decreasing or increasing inadmissibly and at the same time protect the installation against unnecessary energy losses. The closed-cell material structure prevents water penetrating the insulation material and the pipes corroding. SH/Armaflex and Tubolit fulfil the requirements of DIN 1988, part 2 and 7 and the energy-saving regulation.

Victaulic Helps Carrefour Group To Meet Tight Deadlines for Execution

In the past 40 years, the Carrefour Group has become one of the most important distribution companies in the world. Carrefour, currently the largest retailer in Europe, is responding to growing demand for shopping centers in Romania through a large expansion project that includes building two hypermarkets sites of 8.000sqm in Sibiu and in Brăila.

The task of installing the heating, ventilation, air conditioning and fire protection systems in both hypermarkets went to Promteh company, a leader in the installation work in Romania, which had to meet tight deadlines for implementation.

Having available only two weeks to install the 13.5 kilometers of pipelines for fire protection system in Carrefour hypermarket within City Mall shopping center in Sibiu, Simona Chircea, operations chief within Promteh, decided to use in the hypermarket and in adjacent galleries, as well as in the smaller shops a solution offered by Victaulic.

By using Victaulic FireLock EZTM Style 009V (42mm-168mm diameter), fittings, valves and Victaulic sprinklers, Promteh company managed to meet the tight deadlines for implementation and to reduce working hours up to 30%.

In addition to the construction of Carrefour hypermarket in Sibiu, Promteh dealt with the installation of the heating, ventilation and air conditioning systems from Carrefour hypermarket within Harmony complex of Brăila.

A key factor for the success of both works was the choice of suitable products from the beginning. Because the Victaulic product range was previously used in other centers and commercial projects, Promteh team was aware that the use of a mechanical piping system together with the latest generation of Victaulic ready to use couplings would be the best solution for speeding the installation.

SLE W Tank in Tank Stainless Steel Bi-energy Boilers

“Tank-in-Tank” system “Tank-in-Tank” is a heat exchanger with a built-in accumulator, made up of two concentric tanks: the inner tank contains domestic water to be reheated (secondary) and the outer tank contains the heating fluid (primary) which circulates between the two tanks and transfers its heat to the domestic water.

Domestic Hot Water cylinder The inner tank is the heart of the tank: it is subject to the aggressiveness of the supply water, to high pressures and to variations in temperature. This tank is made of solid chromenickel stainless steel (stainless steel 304 or duplex), fully welded under argon protection using the Tungsten Inert Gas (T.I.G.) technique.

Before assembly, the convex bottoms are pickled and passivated in order to improve the tank’s lifespan and in particular its resistance to corrosion. The shell is corrugated all the way up using an exclusive manufacturing process. This design gives considerable resistance to pressure and limits the adherence of lime scale by allowing the tank to expand and contract.

Outer tank The outer tank containing water from the primary circuit arriving from the boiler, is made of carbon steel STW 22.

Thermal Insulation This is carried out using high density injected polyurethane foam, 50 mm containing no CFCs.

Lining The tank is covered using polypropylene, a plastic material which offers a high resistance to shocks and which is also very pleasing to the eye.

The Solution for Preventing Bacteria in Hospitals… Copper, Says Specialists

Did you know that the US Environmental Protection Agency announced officially in March that the first metal with proved antibacterial qualities is copper?

Scientists from various research centers examined the materials with whom people suffering from various diseases as well as visitors come in contact. While on steel, aluminum and plastic surfaces bacteria live more than 30 days, on copper surfaces they don’t live more than 90 minutes.

Moreover, copper (like brass and bronze) prevent some affections caused by bacteria. Besides its medical and specialized uses, copper can be used in other domains too, for heating or water pipes, not only in hospitals but in our homes too.

Are You Confident in the Water Your Child is Drinking?

Did you know that drinking water can sometimes contain microorganisms affecting directly our health? The best solution suggested by specialists for our homes is the use of copper. Most of the problems related to drinking water are caused by infections in the water distribution networks (water pipe).

A research conducted by the Watercycle Research Institute in Holland revealed that using copper pipes prevents the developing of bacterium causing legionnaires’ disease.

It is about a bacteria developing especially in large climatization equipments, as well as in water pipes. Legionella bacteria affect our lungs, in some cases being fatal.

As a result of observance during one year of some domestic hot water supply installations, where water was delivered through copper pipes, the bacteria concentration was 10 times less than in plastic pipes.

Some of the main advantages of copper pipes include: blocking the development of bacteria in water carried through these pipes; they are waterproof and due to their tightness, protects the water from external organic contaminants; copper is a natural product, totally recyclable; it is very resistant at pressure variations; very resistant to high temperatures (in case of fire it doesn’t emit toxic gases).

Therefore, copper protects water quality, being preferred to other materials both in Europe and America, especially for drinkable water.
