How can I safely use pipe gas?

Pipeline gas relative to the traditional liquefied gas is both convenient and economical, but the safe use can not be ignored, the recent gas safety accidents around the frequent, in this way to share the safety of pipeline gas use common sense.

Normal pipe gas flame color is light blue, if it is yellow or red, may be stove pipe is poor, or pipe network pressure is too low. At this time you can call the service hotline for advice and repair.

It is strictly forbidden to seal the various vents of the kitchen and keep the indoor and outdoor ventilation so that even if the indoor gas leaks, it can spread as soon as possible to the outside and reduce the risk of deflagration.

Always pay attention to check the connection between the stove and the pipe hose, to prevent aging leakage, usually should be replaced once a year.

Stove hit the fire, or use the fire when the fire or intermittent and so on and other symptoms, should be stopped in time to use, make stove after-sales service, timely maintenance.

Actively cooperate with the gas company for security checks, usually the gas company every two years will organize a comprehensive indoor gas safety inspection. Once at home smell the rotten eggs, the smell of gas leaks, should avoid the fire, the timely closure of the power gate, window ventilation, went to the open air to call the phone alarm and reported after-sales service.

Without the relevant permission and professional advice, is strictly prohibited unauthorized access to various types of gas.

Cooking and cooking time, the stove should not leave, do a good job should be closed after the stove and the valve, stove should choose a stove with a flame protection device.

It is strictly forbidden to hang things on the gas pipe, drying clothes, or wrapped in gas piping with something. If the home decoration is any change or influence to the pipeline, the gas company should be consulted in time.

Gas pipe transformation process

gas pipe transformation and do not want to change the work of other home improvement, not anyone or any company can transform the transformation of the gas pipe must be operated by the gas company’s gas station, the general community are vested with a gas station, You need to ask the professional staff to carry out the transformation of gas, the following look at the gas pipe transformation process:

  1. Any need to install or modify the gas pipe, should be prior to the direction of market development by the owners of the application, the gas company organized by the scene of the investigation, until the success of the application before they do the next transformation.
  2. Account opening and the need to carry an account notice, the owner of the ID card and real estate license and lease contracts, etc., and the gas company signed a good civil air supply contract, the payment of some account fees, within 5 working days, the gas company personnel Can be installed on site.
  3. If the owners of the layout of the gas pipe is not very satisfactory, you need to do the transformation of the project. The indoor gas pipe facilities, the transfer or modification are required to apply to the gas company, and pay the cost of exploration, pending home visits professionals can be based on the requirements of the owners of a reasonable transformation of the total cost of settlement.

Installing gas piping

1. Determine proper size

Proper sizing of the pipe is important so that each gas appliance receives enough gas to perform properly. Each appliance has a minimum input demand in BTUs per hour. The chart below gives some examples of typical BTU demands. Look at the chart on the back of this insert to assist you in determining the proper pipe size for your job. To convert from BTUs to cubic feet per hour divide BTU by 1100 (example: 50,000 BTU by 1100 = 45.45 cubic feet of gas per hour). See the example on the back of this insert to help further illustrate this. To get BTU from cubic feet, multiply cubic x feet 1100 (45.45 cubic feet x 1100 = 50,000 BTU.)

2. Approved gas piping fitting materials

Black iron and corrugated stainless steel (CSST) are commonly used approved materials. CSST requires certification from the manufacturer for anyone who is going to purchase and install the material.

3. Cutting pipe

If you are cutting iron pipe, you must ream the cut of your pipe so you maintain the full inside diameter of the pipe.

4. Special instructions

Do not use ground joint unions except directly at the meter or after the shutoff valve at the appliance. Each place where you will have a gas appliance must have a gas shutoff valve. Within the City of Seattle only, any person who installs gas piping on property not under their ownership must possess a Seattle Gas Piping Mechanic License. All gas piping installations require a permit and inspection.

5. Testing

Testing the system is your responsibility. The inspector does not perform the test or provide any of the equipment necessary for the test, including test gauges.

An air pressure test is required. The test pressure shall be at least 1 ½ times the working pressure, but no less than 3 pounds per square inch (psi). The test duration shall not be less than 10 minutes. The piping system shall withstand the test pressure specified without showing any evidence of leakage or other defects. Mechanical gauges used to measure test pressures shall have a range such that the highest end of the scale is not greater than five times the test pressure. For instance, a 3 psi test will require a maximum 15 pound gauge. A 10 psi test could be performed using a 50 pound gauge, but not a 100 pound gauge. The piping system shall be under test (pressurized) and the test gauge visible at the time of inspection. Where the gauge does not indicate the minimum pressure required for the test, or any reduction of test pressures as indicated by pressure gauges during inspection shall be deemed to indicate the presence of a leak.

If there is a drop in pressure, check for leaks. Check for leaks by filling a spray bottle with soapy water and spraying the solution on the pipe, where it meets the fittings. Bubbles show a leak and you should repair it appropriately. Continue this process until you have no leaks. Do not use an open flame to test for leaks.

6. Inspection

At the time of inspection, be sure to leave all of the gas piping exposed so the inspector can look at the whole system.
