10.  Application: Versatility of press fittings can widely use in potable water system, water supply and drainage, heating and cooling water circulation system, fire services sprinkler system, gas system and etc.
11.  Characteristics:
Zhengkang pressfitting system is very easy and quick to install and only uses stainless steel AISI304 L316L, carbon steel.
The fittings used in Zhengkang pressfitting system have a toroidal chamber at their own ends inside which there's a EPDM/NBR gasket. This has a very strong resistance against aging. Compared with traditional pipeline system, it’s not only more economical, safer and healthier, but also easier and faster for installation with longer service life.
12.  Press fitting pipeline system was first adopted in Germany in 1960s, which is widely used in cold hand hot water supply, heating supply, fire protection, medicinal gas, industrial petroleum pipeline system, marine pipeline system etc.. Our pipes and fittings ZHENGKANG brand are adopted by many national key projects, such as the National Stadium (Nest), the Crown of East (Shanghai Expo), and the city for Asian Games, Kempinski Hotel, Iran Airport, etc.
