C-PVC FIRE PROTECTION SYSTEM

The fire protection piping system of the future

The fire protection pipe and joints have undergone temperature/pressure tests and other strict performence tests for wet sprinkler application and high-pressure sprinkler application. Advanced coutries have already established national standards to apply cpvc pipes to fire protection for better performance and greater sticefaction.

Self-extingushing property

As CPVC requires three times more oxygen than the atmosphere in order to combust,
it does not burn and generates less smoke or spark to cause fire.

Excellent Corrosion-resistance and Eco-friendly Properties

As CPVC pipes are ircorrodible there is no scale so rust caused by corrosion do not block the hole of sprinkler head. With antistatic agent, the pipes do not accumulate scale and CPVC materials and adhesives are harmless to the human body or the ecosystem.
