Procedure of transfer pipeline

Basic requirements for the transfer of and compliance with safety rules.

Before starting any work on the gas pipes to reinstall, you must apply to the gas supplier.This is done to ensure that you have the opportunity to consult a qualified expert who will examine and determine the possibility of carrying out such work.If necessary, it will make a new installation of the gas pipeline project.Thereafter, gas service sends gasman that and do the entire scope of work.In themselves, they must have the appropriate permits and ID cards.

sequence of transfer following:

• Step One.
  
  The first thing to do - turn off the tap on the gas pipeline to prevent a flow of gas into the house;
• Step Two.Further
  
  necessarily blow pipe to remove gas accumulated therein;
• Step Three.
  
  And only then can be cut portion of the pipe, which will change the cut is sealed and the welding machine;
• Step Four.

Then choose a place on gazovode, which will be powering the new branch and made a hole.Finally, to the opening of a new welded tube, to which later connect all gas appliances.

Upon completion of work shall be drawn up of reception and transmission, which lists all the types of work performed.These data are transferred into the gas passport.

Installation of the gas pipeline to the fulfillment of certain requirements pomescheniipodrazumevaet:

• distance between the water and gas pipelines must be calculated so as to ensure unhindered access to these communications;
• not install gas pipes on windows and doors, and vents;
• distance from the pipeline to the other communication networks (electrical, radio and television, the Internet) is calculated according to the SAE requirements;
• in a private house pipe laying height is 2.4 m above the floor;
• accordance with the requirements of SNIP installation of pipes on the walls or ceiling is carried out by fixing them with special mounts or brackets;
• fastening pipes transporting liquefied gas, produced in an inclined state, an angle which is not less than 3.5%;
• crossing the gas line with other types of communications, the pipe should be wrapped with a special material, such as rubber tarred.

outer part of the pipe necessarily painted to protect them from moisture and corrosion nedopuskaniya.

Features of welding.

Welding work should be carried out with utmost care and in compliance with all the necessary rules for installation of the pipeline elements.Welding gas pipe is performed only by experienced worker, having the appropriate security clearance.

use two types of steel tubes and the production of plastic gas structures.Since

different material is used, and the type of welding to be different, depending on the wall thickness, diameter, and so on.This might Bat arc, argon or gas welding.Any of these techniques is suitable for use, and has its own advantages and disadvantages in each case.
