950kg/m3 4.2Mpa CCC 100L FM200 Fire Fighting System

CCC, FM-200 - Fire Protection, Fire Safety Provider,100L

1. The pipe connection

At the nominal diameter is equal to or small f 80 mm pipeline accessories, appropriate USES threaded connections: nominal diameter larger than 80 mm pipeline accessories, should use flange connection.

Has galvanized seamless steel pipe should not be connected by welding, and choose the individual with the flange connection parts such as valve welding, deal with the damaged by welding galvanized layer another do anticorrosive processing.

2. The installation of the casing

Through the wall, the roof should be installed casing pipe. Wear casing wall length should be equal wall thickness, across the floor of the sleeve length should be higher than the ground 50 mm. The space between the pipe and casing should adopt flexible non-combustible material tamping compaction.

3. Special installation

IG541 fire extinguishing system, carbon dioxide extinguishing system pipeline, halon 1301 fire extinguishing system of tee joint shunt export shall be as shown in figure 3-20 horizontal installation, and should not be installed as shown in figure 3-21.

4. The installation of monitoring components

Each protective zone should be set on the main pressure signal or traffic signal, to send a signal that cast fire extinguishing agent. Annunciator shall be located in choose the bottom valve.

5. The pipe fixed

Piping system must be fixation, can withstand the extinguishing agent produced by the jet thrust and temperature change caused by the expansion and contraction, withstand the mechanical, chemical, vibration damage or other effects.

(1) pipe support and hanger biggest space may refer to table 3-14.

Table 3-14 pipe support and hanger largest spacing

(2) the end of the pipe nozzles shall adopt "bracket, bracket and sprinkler pipe length should not be greater than 500 mm.

(3) the nominal diameter greater than or equal to 50 mm ZhuGanGuan channel, the vertical direction and horizontal direction at least each shall be equipped with an anti sway bracket, through each layer should be set when a multistory buildings sway bracket. Level through long should add anti sway bracket,

(2) pipe purging, test and paint

Have a network of seven fluorin propane gas fire extinguishing agent pipeline purging, test and apply reading should meet the following requirements.

(1) fire extinguishing agent pipeline after the installation, should carry on the water pressure strength test and pressure leak test.

(2) water pressure strength test pressure meet the following requirements.

(1) 1211 halon fire extinguishing system's way of hydrostatic strength testing pressure measured by type (3-1).

(3) high pressure carbon dioxide extinguishing system pipeline hydraulic pressure strength test pressure of 15 mpa.

(3) the protection zone is unfavorable to the water pressure strength test, pressure strength test can be used instead. Air pressure strength test pressure shall be the water pressure strength test of 0.6 times. Effective security measures must be taken when testing.

(4) during pipeline strength test, the pressure to test pressure, pressure maintenance 5 min, check each joint of the pipe should be no obvious drip, visual pipe should be no deformation.

(5) air or nitrogen gas pipeline pressure leak test can be used as the pressure medium,

Two-thirds of test pressure for water pressure strength test. After the test will be pressure to test pressure, shut off the test

5, safety relief valve
Safety relief valve is used to prevent the system from overpressure.
6, the selector valve
When there is a network of seven fluorin propane fire extinguishing system to protect multiple partitions, the selector valve used to control the fire extinguishing agent into the corresponding reserves. According to the size of the calculating pipe diameter, choose the choice of appropriate diameter valve.
7, signal pressure
Pressure signal, signal feedback agent application.
8, nozzle PLPT
Used for discharge agent.
9, high pressure pipe
High pressure pipeline used to transport agent.
10, high pressure pipe fittings
High pressure pipe fittings used to connect to high pressure pipeline.

1, pipe network system through network discharge, nozzle evenly, so the uniform discharge, extinguishing effect is good, and no nozzle directly discharge pipe network are generally enclosure, discharge point is so a bit, discharge is not uniform;

2, a pipeline needs to be set separately between the cylinder and set up the network, without network don't need to, if only to protect a area, from the economic Angle has a high cost of pipe network system.

3, if more than one area, there are more than pipe network system can use the same set of system protection protection zone. Different fire protection area, specific discharge, without network need to be set separately for each protection zone cylinder and fire extinguishing agent, this time without the price of the pipe network is higher.
