1. ENGINEERING PLUMBING AND SANITATION Executes Application of Gas Pipe Installation

2. Teknologi dan Rekayasa Purpose Of Instructional Public : After this lesson solvent student and understands in explaining about kinds and gas property. Purpose Of Special Instructional : Student can mention : 1. Kinds and gas properties. 2. Various material gas which is easy bursts and arising danger. 3. Some baking factors and baking difference from phase baking.

3. Teknologi dan Rekayasa Kinds and Gas Property 1. Kinds Of Gas : In general gas produced by pertamina is :  LNG ( Liquefied Natural Gas), obtained from ground consisted of by mixture various black coal fluid compounds ( Paraffinic hydrocarbons) that is Methane, Ethane, Propane, Butan

4.  LPG ( Liquefield Petroleum Gas) obtained by way of compression and cooling of gas hence formed [by] two kinds of gas that is Butane and Propane utilized for in Household.  CNG ( Compressed Natural Gas) utilized for automobile fuel. Teknologi dan Rekayasa

5. 2. Gas Properties : Teknologi dan Rekayasa

6. 3. Danger and precaution  If mixed and gasiform had fuel with oxygen from the air.  The gas would easily be combustible or bursts if it is around the gas there are fire causing can generate a real blast endangers for safety of man soul. Teknologi dan Rekayasa

7.  Prevention : Teknologi dan Rekayasa Its way :  People must understand about character from gas which explosive ( Acetylene, Propane, Butane).  People must understand about safe way of working.

8. 4. Baking process Gas 4.1. Baking Factors 4.2. Kinds of baking difference 4.3. Phase baking Teknologi dan Rekayasa

9. 4.1. Baking Factors : Teknologi dan Rekayasa The component is : Fuel consisted of by C and H Oxygen from the air Fire Burning temperature

10. 4.2. Kinds of baking difference : Teknologi dan Rekayasa Slow baking is processing fireless baking For example : In human body Strong baking is processing baking using fire. Baking on the spur of the moment was processed baking happened quickly once if there is cause in vinicity.

11. Gas and the equipments  THE WORK PRINCIPLE : Cool water flows with certain dividing valve passed admission passage that is then fulfills temperature governor room. Arising dividing valve pushs membrane to ride on and pushs also open gas valve peduncle, gas will enter through gas valve and exit through principal incendiary. Teknologi dan Rekayasa

12.  Then fire is flamed [by] hence mixed has gas with oxygen can be combustible.  Cool water flows after through nozzle to get speed of flow from at the water pressure, then water chilled through which heater wall in it there is incendiary fire and then went out from cool water heater wall turned into temperature water is opened.

16. Rule of Installation of Gas 1. Installation Scheme of Gas : Teknologi dan Rekayasa 1.1. Meter gas in each floor Installation with this system usually utilized at apartment which different building dweller so that usage of gas also different 1.2. Meter gas at underground space : Placement of meter gas at underground space or to certain space. This thing hardly facilitates for officer to investigate usage of gas each month

17. 2. Application of Gas pipe 2.1. In ground Not under building for example : under garage automobile Pipe is planted with minimum depth 80 cm Pipe is attached with dip 1% At low place is given [by] impurity dumper valve Must be given pipe canopy if installation pierces building wall Teknologi dan Rekayasa

18. 2. In building :  Pipe must be diametrical and applies fitting  Pipe is not bended  Labours doesn't there are joint / fitting through wall Teknologi dan Rekayasa

19.  Pipe may not be attached through / near by smokestack, above garbage-can; heater space and near by installation pipe of temperature water.  Pipe is attached with klem which is strong at wall. Teknologi dan Rekayasa

20. 3. Kinds of gas pipes : 3.1 In ground  Black steel pipe ( gas pipe)  Galvanic steel pipe  Iron pipe decants Teknologi dan Rekayasa

21. 3.2. In building :  Black steel pipe  Galvanic steel pipe  Copper pipe  Brass pipe  Aluminum pipe Teknologi dan Rekayasa

22. 4. Tacking on pipe  At installation of joint gas that is usually is utilized is :  Knuckle joint  Weld joint  Hard solder joint  Flange joint Teknologi dan Rekayasa

23. Inspection and Testing In inspection and installation testing of pipe usually is done two phases for Instalasi which is new that is :  Initial assaying : Initial inspection at installation of gas is testing compress until 1 bar without accessories of installation until having dividing valve 1 bar during minimum 10 minutes. During the may not be accentual gone down. Teknologi dan Rekayasa

24. Principal assaying :  At principal assaying that is done for installation of new gas and stripper. This test done at all installation of gas in building is started [by] meter gas to come up with tip of joint to gas equipments.  This principal assaying by using pipe manometer U with dividing valve 50 m bar, during 10 minutes. Where during the there shall no pressure drop

25. Step of peacemaker : Steps that is must be done if kissed gas aroma when doesn't apply equipments of gas that is :  All devices which can generate fire is extinguished.  Principal gas valve is closed  Doesn't change position of switches  Lamp fuse may not be released  Window and door of soon is opened  Doesn't smoke  Then departs from for a few when until gas aroma is not too sharply Teknologi dan Rekayasa
