THE Machines SA, Yvonand Switzerland, has developed a series of Laser welding machines with which is possible to weld powder-, lack- or polymer coated thin wall metal stripes and foils. Prior welding the coating has not to be removed. The machines working fully automatic and can be delivered as stand alone units or they can be incorporated in continuous working production plants.
KWD-globalpipe, 2009-11-21. (PEX, PE-RT and multilayer pipes) Rofix, an international group of companies, has set new standards for fastening technology in the plumbing and heating industry. The company was founded 25 years ago and has since emerged as a leader in radiator and pipe hangers and struts. The company employs 200 workers in 4 factories, two of which in Belgium, and one each in Poland and China. Located in Dilsen, Belgium, the sales headquarters serves their various sales organizations in Belgium, The Netherlands, Germany, Austria, France, Poland, Greece and the United States. This combination makes Rofix an international leader in fastening techniques. (more…)
Rifeng launches its new generation manifold kit for heat regulation center–FN5C. The manifold kit has inlets and outlets from 2 to 12 ways for various choic es. Polished by advanced techniques, FN5C is of shining appearance with splendid colors: original and nickeld for different preferences. Furthermore, its flow gauge is colored in red and switch knob in blue to indicate delivery and return side, on top of indication arrows on the manifold bodies. (more…)
In Blansol Multipex Pipes (’alupex‘), both the inner and outer layers are made of cross-linked polyethylene (PEX). This improves their behaviour in comparison with non-cross-linked multilayer pipes. PEX is the ideal material for multilayer pipes working in applications where high temperatures are required (up to 95°C), such as the connection of radiators in heating applications.
Blansol PEX/AL/PEX multilayer (’alupex’) pipes have superior performance with regard to connection viability. Multilayer pipes based on cross-linked polyethylene (PEX/AL/PEX), ensure that the compression force at the union is maintained even at high temperatures (over 95°C). Other polyethylenes which are not cross-linked, melt at these high temperatures, so the wall-thickness of the pipe becomes thinner, reducing the compression force of the union with an increased risk of leakage.
Butt-Welded Aluminium
Blansol Multipex pipes have their aluminium layer butt-welded. This improves their resistance to both internal pressure and to the stress generated when the pipes are bent during installation. In the butt-welded multilayer pipes, the welding line of the aluminium layer is the strongest point of the layer. (more…)
Maillefer is a well known provider of multi-layer composite pipe manufacturing systems for PEX-AL-PEX pipes. The Swiss company has recently introduced new aluminum forming and welding bench components into its PCL lines. In comparison with what’s available in the market, shorter setups, improved weld control and reduced maintenance qualify the Maillefer equipment. All new PCL lines offered include the latest technology. Plus, the equipment is also available as an upgrade to existing lines

Automatically pressing push fit fittings – what sounds like a contradiction is the new patented technology from Zewotherm for metal composite pipe for under-floor and general heating as well as sanitary applications. While pushing the pipe into the fitting a metallic press ring inside the push fit fitting jumps out and presses the pipe completely tight and inseparable onto the supporting shell of the fitting. The family-run company provides a 25 year warranty for the system.
Quick, safe and clean: To work the new connector system from Zewotherm neither a compression tool nor time-consuming training is required. Clean installation for heating or potable water pipe and easy handling enable plumbers to save time and money, and for the complete piping system a 25 year warranty is provided. (more…)
Paving the way to ultimate globalization, and also combining multiple applications(drinking water,heating,gas,etc) in one pipe, the KIWA & KOMO certificates we just obtained for our PEX/AL/PEX multilayer pipes and press fittings are among the almost 50 overseas certificates we have obtained so far. Our newly obtained KIWA & KOMO certificates currently cover both drinking water (with KIWA mark) and heating application(with KOMO mark), with certified dimensions including 16 X 2mm, 20 X 2mm, 25 X 2,5mm and 32 X 3mm, our KIWA-approved press fitting is made of hygiene-approved De-Zincification Resistant brass. For details on our overseas certificates please visit the following weblink: http://www.rifeng.com/certificates.asp
At the ISH 2009 Uponor has introduced the new generation of the multi layer composite pipe system for tap water installation and radiator heating. The important innovation of the system for the outer dimensions from 14 up to 32 mm: No more calibration and bevelling is needed. For the plumber that means less tools and to save one entire working step which leads to a time reduction of about 30% for the press connection. After cutting, the pipe can immediately be inserted into the fitting and afterwards has only to be pressed with the respective tool. The further advantages of the innovative system are still valid.
