Description

Дл  предотвращени  попадани  кислоты в зону сварки должно выполн тьс  соотношение . Дл  обеспечени  выхода углекислого газа в зону сварки должно выполн тьс  соотношение а гидравлическое сопротивление столба кислоты должно быть больше сопротивлени  массы соды, что достигаетс  подбором соответствуюш,его размера кристаллов .To prevent acid from entering the weld zone, the ratio must be maintained. In order to ensure the release of carbon dioxide into the welding zone, the ratio must be satisfied and the hydraulic resistance of the acid column must be greater than the mass resistance of the soda, which is achieved by selecting the appropriate size of its crystals.

Заглушка и капсула выполнены из материала , раствор юш,егос  в кислоте, и удал ютс  при гидроиспытани х или наполнении трубопровода кислотой.The cap and the capsule are made of a material, a solution of acid, which is dried and removed by hydrostatic testing or the pipeline is filled with acid.

Claims (2)

1. Способ заш,иты обратной стороны сварного шва, преимуш,ественно при ремонте кислотопроводов с остатками кислоты, при котором заполн ют зашитным газом камеру внутри соедин емых трубопроводов в зоне стыка, отличающийс  тем, что, с целью снижени  расхода газа от внешнего источника , повышени  безопасности работы и уменьшени  трудоемкости, в качестве заш;итного газа используют продукты реакции остатков кислоты , наход щейс  в зоне стыка трубопроводов , и вводимой в камеру соды.1. The method of stitching, and the back side of the weld, is advantageous when repairing acid pipelines with acid residues, in which the chamber inside the connected pipelines is filled with a protective gas in the joint zone, characterized in that, in order to reduce gas flow from an external source, increasing safety of work and reducing labor intensity, as a protective gas, use the reaction products of acid residues located in the junction of pipelines and introduced into the soda chamber. 2. Устройство дл  осуществлени  снособа по п. 1, содержащее камеру с двум  заглушками, отличающеес  тем, что одна из заглушек выполнена в виде полой капсулы, стенка которой со стороны второй заглушки имеет газопроницаемый участок, а в другой стенке выполнено отверстие дл  заполнени  капсулы кислотой и содой, при этом капсула установлена с возможностью поворота.2. A device for making removal according to claim 1, comprising a chamber with two plugs, characterized in that one of the plugs is designed as a hollow capsule, the wall of which has a gas-permeable portion on the side of the second plug, and an opening for filling the capsule with an acid in the other wall and soda, with the capsule set to rotate.
