Sell Hansen Fitting Male Threaded Adaptor (20 25 32)mm (MTA) (For Poly, Poly Aluminium Pipe) best price

~APPROVAL Approved by the Water Supply (Water Quality) Regulations 1989 & Water Regulations Advisory Committee (WRAS) of UK for its use in potable water, this material is superior to existing materials being used in terms of strength and ability to withstand heat. The fittings are designed and comply to British Standard BS 5114: 1975 (1981) (AMD.2 - 1987) and ISO 22391-3. ~MECHANICAL PROPERTIES Hansen fittings, together with high density polyethylene (HDPE) pipes or polyethylene - raised temperature (PE-RT) pipes, provide an unsurpassable potable water system. These sleek fittings are slim enough to be buried in walls and are able to withstand very high pressures. ~TEST UNDERGONE BY THE HANSEN FITTINGS AND PIPES SYSTEM 1. The only plastic fittings system for portable water in Malaysia to have under gone the cyclic pressure shock test Tested at 23°C ± 2ºC for 10,000 cycles of alternate internal positive pressure of 1 bar ± 0.5 bar and 15 bar ± 0.5 bar at frequency at least 30 pressure cycles per minute. 2. Resistance to pull out the assembled joint The joined assembly is applied at a constant tension for 1 hour on the basis that it is subjected to a maximum internal test pressure o7 37.5 bar. 3. Hydrostatic pressure test The assembly shall withstand without leakage for 1 hour an internal positive pressure of 3 times its maximum sustained working pressure which is 37.5 bar. 4. Hydrostatic requirement when subjected to bending stress When the assembly is bent to a radius of 20 times the diameter of the pipe, the joined assembly shall withstand for 1 hour without leakage an internal positive prssure of 37.5 bar. 5. External pressure requirement The joined assembly shall withstand for 1 hour without leakage, a pressure of 0.80 bar above atmospheric pressure. 6. Effect on water complies to BS 6920 : Part 1 and Part 2. 7. Opacity the wall of the fittings shall not transmit mre than 0.2% of the visible light falling on it. #Plumber #Hansen #Fitting #Hansenfitting #polyfitting
