Известны способы уплотнени стыковых соединений трубопроводоз с применением материала со спирторастворимой смолой, также общеизвестно применение уплотн ющих растворов, в состав которых входит цемент , известь и песок.There are known methods for sealing butt joints with pipelines using a material with an alcohol-soluble resin, it is also well known to use sealing solutions that include cement, lime and sand.
Недостатком известных растворов вл етс недостаточна надежность уплотнени стыков и, как следствие этого, случаи утечки транспортируемых по трубопроводам газов и жидкостей.A disadvantage of the known solutions is the lack of reliability of the sealing of the joints and, as a result of this, cases of leakage of gases and liquids transported through pipelines.
Предложенный способ получени уплотн ющего раствора дл стыковых соединений трубопроводоз из асбестоцементных труб устран ет этот недостаток и обеспечивает повышение надежности стыков при давлении до 7 кг/см- за счет того, что в состав раствора.в качестве в жущего ввод т цемент и фенолформальдегидную смолу, состо щую из 100 вес. ч. кристаллического фенола, 82 вес. ч. формалина, 3 вес. ч. 25% гидрата окиси аммони и 20 вес. ч. воды.The proposed method of obtaining a sealing solution for butt joints of pipelines made of asbestos-cement pipes eliminates this drawback and provides an increase in the reliability of the joints at pressures up to 7 kg / cm due to the fact that cement and phenol-formaldehyde resin are introduced into the solution. consisting of 100 wt. including crystalline phenol, 82 wt. including formalin, 3 wt. including 25% ammonium hydroxide and 20 wt. h of water.
В зкость готовой смолы должна быть не менее 150-200 сек. по воронке ВЗ-4, а удельный вес 1,15-1,17. В качестве заполнител примен ют речной песок с размером 0,15-0,85 мм по ГОСТу 2781-50.The viscosity of the finished resin must be at least 150-200 seconds. on the funnel VZ-4, and the proportion of 1.15-1.17. River sand with a size of 0.15-0.85 mm according to GOST 2781-50 is used as a filler.
В раствор дл зачеканки стыков (смесь) вход т цемент, песок, известь и смола в соотношении 1 ; 3 : 0,125 : 1.The mortar for the butts (mixture) includes cement, sand, lime and resin in a ratio of 1; 3: 0.125: 1.
Способ получени уплотн ющего раствора дл стыковых соединений трубопроводов из асбестодементных труб, отличающийс тем, что, с целью повыщени надежности уплотнени стыков, в состав раствора в качестве в жущего ввод т цемент и фенолформальдегидную смолу, состо щую из 100 вес. ч. кристаллического фенола, 82 вес. ч. формалина, 3 вес. ч. гидрата окиси аммони и 20 вес. ч. воды.The method of obtaining a sealing solution for butt joints of pipelines from asbestos-deduced pipes, characterized in that, in order to increase the reliability of the sealing of the joints, cement and phenol-formaldehyde resin consisting of 100 wt. including crystalline phenol, 82 wt. including formalin, 3 wt. including ammonium hydroxide and 20 wt. h of water.
