Pipelines pressure head lengthy with a diameter of 65, 72 and 76 mm, intended for charging of wells to elastic explosive are developed and are made
substance (EVV) by its pumping in wells when carrying out explosive works. Can be applied in the state which is reeled up on a drum that considerably simplifies their transportation.
Pressure head lengthy pipelines also intend for transportation of substances with the content of gasoline, diesel fuel, oils on an oil basis, waters technical, weak solutions of inorganic acids and alkalis of concentration to 20.
Pipelines pressure head lengthy consist of an inside rubber layer, a power framework and a protective external rubber layer. Working pressure of the pipeline (sleeve) to 1,2 MPas, the radius of a bend is equal to 10 diameters, the maximum length of one piece of 100 m.
Lengthy pipelines when transporting are turned in bays with a diameter not less than 1250 mm.
