Product Description
Technical characteristics: Products are made to individual orders.
This groove adapter tee is a specialized fitting for branches and diameter changes in fire extinguishing and water supply pipelines. The body is made by one-piece casting from high-strength nodular cast iron QT450-12. The product strictly complies with the requirements of the national standard GB5135.11-2006 “Sprinkler-type automatic fire extinguishing systems. Groove fittings" and the American international standard for materials ASTM A536. The metal structure is stable, high viscosity, resistant to water pressure and vibration loads, which provides operating pressure up to 2.5 MPa for fire extinguishing systems.
O-rings are available in two types: ethylene propylene rubber (EPDM) for fire piping and food grade silicone rubber for drinking water systems. The products meet the requirements of ISO6182 and GB/T17219 standards, are resistant to aging, high and low temperatures, and provide leak-free sealing. The mounting bolts and nuts are made of 45# or 40Cr steel with hot-dip galvanized anti-corrosion coating, strength class 8.8, dimensions meet government fastener standards.
The outer surface of the fittings is treated by electrostatic spraying of epoxy powder paint with high-temperature polymerization. The coating is characterized by uniformity, high adhesion, non-toxicity and environmental friendliness, suitable for fire extinguishing systems and drinking water supply. Coating standards comply with GB/T13492 and GB/T13657.
The products are manufactured in full compliance with state standards for groove fittings; the grooves on the ends of the pipes have precise dimensions. Installation is carried out using groove couplings without the need for welding, which ensures high installation speed. Widely used in fire sprinkler systems, municipal water supply and drainage systems, as well as in heating and ventilation pipelines of industrial facilities.
