groove coupling pipe fitting,
flexible grooved coupling
stainless steel Equal cross Zhengkang groove fitting
Press fitting pipeline system is widely used in cold hand hot water supply, heating supply, fire protection, medicinal gas, industrial petroleum pipeline system etc.
Groove connection is a new way developed according to foreign data, popularly used in connecting pipes and fittings above DN100mm. The groove pipeline system is a suite of quick couplings consisted by hoops ,gaskets and fasteners, matching with press pipeline system. 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. Compared with traditional pipeline system, its not only more economical, safer and healthier, but also easier and faster for installation with longer service life.
