 Features 
 1, the health of non-toxic, products through rigorous testing, to meet national health standards, can be used for pure water, potable water piping systems. 
 2, high temperature high pressure, and piped the water temperature up to 95 ° C under the provisions of the long-term continuous work pressure. 
 3, corrosion-resistant, does not scale, can avoid the basin of piping corrosion caused by the, bathtub macular rust can avoid pipeline corrosion and scaling caused by blockage. Continuous service life of more than 50 years. 
 4, light weight, high strength, year on year, weighs only 1/8 of the metal tube, good toughness, impact resistance, easy to transport. 
 5, the wall is smooth, water resistance, the pipe head loss than with the specifications of steel more than 20%. 6, superior insulation and energy saving, thermal conductivity is about 1/200 of the metal, used for hot water pipe insulation, energy-saving effect is excellent. 
 7, easy to install, safe and reliable, the use of hot melt connection without wire sets; connection with the metal and water control quality copper inserts, safe and reliable. 

 Product applications 
 Residential hot and cold water piping systems 
 (2) pure water, drinking water pipeline system 
 Industrial water and chemicals transportation, emissions 
 (4) heating and floor radiant heating 
 (5) other industrial, agricultural pipe, galvanized pipe is the ideal replacement 
 Inspection and acceptance 
 After the end of the pipe installation, you must be hydraulic pressure test to confirm its welding and in good condition, otherwise prohibited pipe hidden installation. 
 As follows: 
 1, the end-of-pipe pressure test block, slow injection, while the gas pipeline discharge. Full of water, the water seal check. 
 2, the pressure should slow hand pump boost, rise time of not less than 10 minutes. 
 , Rose to the specified test pressure (usually more than 1.0MPa), stop the pressure. Regulator 1 hour observation joints for leaks. 
 4, regulator, added pressure to the required test pressure value, pressure drops within 15 minutes and no more than 0.05MPa qualified.
