Drinking water, heating and gas, three media, three requirement profiles. Anyone planning or installing pipelines needs to know the differences, because the wrong pipe connection system in the wrong medium can have serious consequences. This article provides clear guidance on which system fits where and what to look out for when choosing a system. <\/p>\n\n
Special requirements apply to drinking water pipes. The material must be suitable for drinking water, must not release any substances that are harmful to health and must remain permanently tight. Seals in press fittings must be suitable for permanent contact with drinking water. EPDM seals are widely used in the drinking water sector because they are resistant to drinking water and many other aqueous media. <\/p>\n\n
Threaded fittings made of malleable cast iron with DVGW certification, such as those offered by HS Fittings<\/a>, are approved for drinking water applications. The increasingly stringent requirements for lead-free materials must be observed. In contrast to certain brass alloys, malleable cast iron does not contain any lead, which positions it well for these requirements. <\/p>\n\n Heating systems operate at elevated temperatures and system pressures. Fittings and seals must be permanently pressure-tight and temperature-resistant. EPDM seals, which are suitable for heating systems up to the typical system temperatures, are often used in the pressing area. <\/p>\n\n The AQUAGAS-V system from HS Fittings<\/a> is expressly designed for heating systems and is DVGW-certified accordingly. The following applies to threaded fittings: Malleable cast iron fittings in accordance with DIN EN 10242 are designed for heating temperatures and system pressures in normal building areas. <\/p>\n Get more information now.<\/a><\/p><\/blockquote>\n\n The strictest requirements apply to gas installations. A leak is not just damage, it is a safety risk. This means that only products with explicit gas approval may be installed in gas pipes. General pressure resistance is not sufficient. <\/p>\n\n Press fittings in gas installations require special seals that are also permanently resistant to natural gas and liquid gas. HNBR seals, such as those used in the AQUAGAS-V system, are suitable for gas. The yellow O-ring serves as a practical identification feature for gas suitability. <\/p>\n\n Malleable cast iron fittings with DVGW certification for gas are also a proven choice and are used in many gas installations in buildings. You can find the relevant technical details in the data sheets and downloads<\/a>. <\/p>\n\n There is no single system for all three media, but dual certification makes storage planning easier. AQUAGAS V is dual DVGW-certified for drinking water, heating and gas. This reduces the number of variants in stock and simplifies ordering for projects with mixed requirements. Malleable cast iron fittings are also available in DVGW-certified versions for several media. <\/p>\n\n Choosing the right pipe connection system is not just a question of price, but of safety and quality. Drinking water, heating and gas place different demands on materials, seals and certification. HS Fittings offers tested and certified solutions for all three areas.
