The diameter of the pipeline

How to build a gas pipeline.Home - half the battle

Before pave gas communications, it is necessary to collect the signatures of the neighbors that are in close proximity to your site.You then need to apply to the city gas service to get permission to connect to the existing central gas pipeline.

gasification project of the house should be drawn up taking into account the individual characteristics of the land, which will host the gas pipe.To compile the optimum pipeline construction schemes will know where the nearest highway, take into account the gas pressure in it.This is important because pipelines categories are divided by gas pressure.Know the category of the gas pipeline conducted on your site you need to indicate in the project, what will be the security backbone area to inadvertently during future construction or upgrading of the site not to damage the pipe.

classification gas pressure pipelines

categories are as follows:

• low pressure line with a working pressure of gas up to 0.005 MPa inclusive;
• medium pressure line working gas pressure of 0.005 MPa to 0.3 MPa;
• high pressure line:
• Gas category I, the operating pressure of which is for the gas-air mixture - 0.6 MPa, for liquefied petroleum gas (SGU) - to 1.6 MPa;
• IIkategorii gas pipelines with operating pressure gas to 0.6 MPa.

For private households should be fine low pressure gas pipelines.

Turnpike low pressure used for the delivery of gas to homes, public buildings, boiler rooms and other facilities.These communications can be embedded private consumers.Protective zone for low pressure pipeline is 2 m on both sides of the pipe.Gas communication medium and high pressure needed to feed the urban distribution networks and supply industry, where production process requires a lot of gas pressure above 0.6 MPa.Security high pressure gas zone is equal to ten meters on either side of the pipe, if I category, and 7 meters if the category II.As you can see, with a buffer zone of increasing pressure increases as the risk of accidental damage to the pipe increase significantly.

Norms gas pipeline

on laying gas terrestrial communications approved standards located in 320mm from the ground, and no less, the pipes should be in places where there are no sidewalks or parking lots.Installation of street roads starts after determining the nearest point to the group of residential houses gasified.This branch point is made, which is then connected to the central pipeline.

During the construction of the underground line and determine the nearest point horizontally from the building to the place of installation planned highway.In one trench is allowed to stack two tubes, but with the condition that they are positioned at different heights.Moreover, if the pipe diameter is 300 mm, the distance between them is necessary to withstand 0.4 m. Stop valves for underground laying located at a distance of 2 meters from the building.More detailed aspects of the process may prompt professionals.
