Ra-sha give you warranty on our water- and gas installations.

We have extended our specialization by using a new gas and water supply system made by COMISA, of Italy. This has recently been introduced in Suriname, but has been used for quite some time in Europe. We deal with all the water and gas pipes installations, such as boiler installation, pump installation and plumbing. One of the reasons we use the multilayer pipes is to prevent copper theft

International certificates issued over the years prove the reliability and quality of this system. COMISA Gas System has the UNI TS 11344: 2009 standard and can be installed according to the UNI TS 11344: 2009 and the UNI 7129: 2009 standards.

The COMISA water and gas distribution system consists of a combined use of the multilayer pipe (5 layers) with press fittings, pronto-fit (push fit) and euro cone couplings. The pipes and the fittings are electrically isolated from each other by the special configuration of the plastic clip, to prevent any contact between the two metals. The use of this system is suitable for both surface and underground installations and the pipes can be installed either flush or surface. The multilayer pipes are suitable for hot and cold water, natural gas and LPG.

The water pipes can endure 95 degree (Celsius) heat and a pressure of 10 bar. Gas pipes endure 70 degree heat and have a working pressure of 0.5 bar. The pipes are furthermore available in all sizes, such as 14 mm, 16 mm, 18 mm, 20 mm, 26 mm, 32 mm, 40 mm, 50 mm and 63 mm. All couplings are available in the form of press fittings, pronto-fit and euro cone couplings.

Another great advantage of these pipes is that they are extremely flexible and have a greater curvature than pipes made of copper. The maximum length of a pipe is no less than 300 meters and can be cut to any desired length. Because these pipes are very flexible, they can be bent much easier and they don’t have to be cut as often as the copper pipes, which will also reduce the use of too many couplings. Because of this, your installation will consist of a few pipes, so that de chance of leakage will be minimal.

COMISA pipes are the ideal material for hot and cold water installations and sanitary systems, for example, for drinkable water installations. Because of the quality of the materials and the ease which goes with the use of our system, you will also save time during the installations. Especially in the Caribbean countries, where working under the bright sun won’t always be easy, you will experience the use of COMISA products as very enjoyable.
