1. Способ предотвращения утечек из фланцевых соединений трубопроводов, включающий разъединение и последующую сборку фланцевого соединения, отличающийся тем, что перед сборкой фланцевого соединения в дополнение к основному уплотнительному кольцу устанавливают дополнительную уплотнительную прокладку, выполненную в виде плоского кольца, а также:1. A method of preventing leaks from flange connections of pipelines, including the separation and subsequent assembly of the flange connection, characterized in that before assembling the flange connection, in addition to the main sealing ring, an additional sealing gasket is made in the form of a flat ring, and also: - с отверстиями для прохода шпилек, совпадающими по расположению и диаметру с отверстиями для прохода шпилек во фланцах,- with holes for the passage of the studs, matching in location and diameter with holes for the passage of the studs in the flanges, - с центральным отверстием, совпадающим по расположению во фланцевом соединении и диаметру с внешним диаметром основного уплотнительного кольца,- with a Central hole that matches the location in the flange connection and the diameter of the outer diameter of the main sealing ring, - с внутренней частью, образованной центральным отверстием, а также имеющей в поперечном сечении по всей длине Т-образную форму,- with the inner part formed by the Central hole, as well as having a T-shape in cross section along the entire length, и содержащую ниппель, позволяющий с помощью манометра контролировать давление в полости фланцевого соединения, образованной между дополнительной уплотнительной прокладкой и основным уплотнительным кольцом, а также производить слив жидких углеводородов, накопившихся в указанной полости.and containing a nipple that allows using a manometer to control the pressure in the cavity of the flange connection formed between the additional sealing gasket and the main sealing ring, as well as drain the liquid hydrocarbons accumulated in the cavity. 2. Способ по п. 1, отличающийся тем, что дополнительную уплотнительную прокладку выполняют из технической резины или мягкой пластмассы или паронита.2. The method according to p. 1, characterized in that the additional sealing gasket is made of technical rubber or soft plastic or paronite.
