Fire Groove Tube what _ Chuanhai machinery (certified) _ Heilongjiang Fire Groove Tube

 Fire Groove Tube means for fire safety, connecting fire equipment equipment, due to fire tube normally quiescent state, and therefore on the tube more stringent requirements, fire grooved fittings required pressure resistance, corrosion resistance Fire Groove Tube price resistance Good high temperature performance. With the current requirements of the development of a variety of new fire fittings and connection technology emerging and effective application of the fire pipe trench in which a variety of practical projects, which require us to sum up, making all kinds of fire class pipe fittings in all kinds of applications, fire protection system is more accurate and economical. Easy installation process firefighting pipe trench is: Preparations → dry pipe valves installed alarm installation → → → sprinkler riser installation stratified Lunar pipe and branch pipe installation → hydrant flow indicator, fire pumps, high water tank, water pump installed pipeline pressure test → → → sprinkler pipe flushing branch pipe installation (integrated pressure test and flushing the system) → → alarm valve throttling device installation accessories, fire hydrant accessories, sprinkler system installation → pass the water test. Fire Groove Tube test work which checks should be done prior to use. 1. vacuum (negative pressure tightness). When vacuum reaches 0.08MPa Fire Groove Tube national standards, maintain 5min, there should be no vacuum pressure loss. 2. gas seal performance. When inflation pressure reaches 0.3MPa, keep the fire Groove Tube 5min specimen surface should be no air bubbles leakage. 3. The sealing performance. Pressure of 2 times the rated working pressure, keep 5min, should be no leakage. 4. compressive strength. Pressure of 4 times the rated working pressure, keep 5min, there should be no leaks and damage. 5. bearing torque. In the moment of action prescribed, with no leakage and breakage.
