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.
