    摘要: LEAKS IN PIPES, PIPELINES AND PIPE SYSTEMS, CONDUITS, CLOSED CONTAINERS, TANKS AND OTHER VESSELS ARE SEALED BY INTRODUCING INTO THE INTERIOR OF THE VESSEL A GASEOUS, VOLATILIZED OR LIQUID VOLATILIZABLE ALOCHOL OR GLYCOL EHTER, APPLYING PRESSURE ON THE INTERIOR OF THE VESSEL SUFFICIENT TO PERMIT ESCAPE OF THE ALCOHOL OR THE GLYCOL ETHER FROM A LEAK PRESENT IN THE VESSEL INTO THE AMBIENT ENVIRONMENT, AND THEN INTRODUCING INTO THE VESSEL A GASEOUS OR VOLATILIZABLE SEALANT AGENT CAPABLE OF REACTING WITH THE ALCOHOL OR GLYCOL ETHER PRESENT TO FORM A SOLID SEAL IN THE SITUS OF THE LEAK. ALTERNATIVELY, THE SEALANT AGENT CAN BE INTRODUCED FIRST INTO THE INTERIOR OF THE VESSEL FOLLOWED BY INTRODUCTION OF THE ALCOHOL OR GLYCOL ETHER.

    摘要: The invention relates to compositions for sealing leaks in pipes, conduits, gas lines, closed containers, tanks and the like. The interior of such equipment is first purged with a nonreactive dry gas, such as nitrogen, to remove any moisture and/or oxygen which may be present. Then the sealant composition is introduced into the interior of the equipment in a suitable inert gas vehicle under pressure. The sealant composition in the gas vehicle will escape from any leaks present in the equipment into the adjacent external environment such as the outer ambient atmosphere or adjacent soil in the case of pipelines buried in soil. The sealant reacts with oxygen and/or moisture to form at the situs of the leak a solid reaction product. The sealant compositions comprise pyrophoric volatilizable alkyl aluminum etherates. Illustrative examples are trimethylaluminum dimethyletherate, trimethylaluminum diethyletherate, and triethylalumin diethyletherate. These and similar compounds may be used singly or in mixtures thereof. They may also be mixed with volatile organo-silane compounds in amounts ranging from about 1 to 99 percent by volume. Specific illustrative organosilane compounds are trimethyl ethoxy silane, dimethyl diethoxy silane, and propyl trimethoxy silane.

    摘要: THE INVENTION RELATES TO COMPOSITION FOR SEALING LEAKS IN PIPES, CONDUITS, GAS LINES, CLOSED CONTAINERS, TANKS AND THE LIKE. THE INTERIOR OF SUCH EQUIPMENT IS FIRST PURGED WITH A NON-REACTIVE DRY GAS, SUCH AS NOTROGEN, TO REMOVE ANY MOISTURE AND/OR OXYGEN WHICH MAY BE PRESENT. THEN THE SEALANT COMPOSITION IS INTRODUCED INTO THE INTERIOR OF THE EQUIPMENT IN A SUITABLE INERT GAS VEHICLE UNDER PRESSURE. THE SEALANT COMPOSITION IN THE GAS VEHICLE WILL ESCAPE FROM ANY LEAKS PRESENT IN THE EQUIPMENT INTO THE OUTER AMBIENT ATMOSPHERE OR ADJACENT SOIL IN THE CASE OF PIPE LINES BURIED IN SOIL. THE SEALANT REACTS WITH OXYGEN AND/OR MOISTURES TO FORM AT THE SITUS OF THE LEAK A SOLID REACTION PRODUCT. THE SEALANT COMPOSITION COMPRISES (1) A VOLATILE METAL ALKYL COMPOUND, AND (2) A VOLATILE ORGANOSILANE COMPOUND. THE VOLATILE METAL ALKYL COMPOUND HAS THEFORMULA M(R)2, WHEREIN M IS ZINC OR CADIMIUM, OR THE FORMULA X(R)3, WHEREIN X IS ALUMINUM, GALLIUM, IN DIUM, OR THALLIUM, AND R IS AN ALKYL HAVING 1 TO 3 CARBON ATOMS. THE ORGANO-SILANE COMPOUND HAS THE FORMULA R4-NSI(OR'')N, WHEREIN R IS AN ALKYL HAVING 1 TO 3 CARBON ATOMS, R'' IS AN ALKYL HAVING 1 TO 3 CARBON ATOMS, AND N IS AN INTEGER FROM 1 TO 4. THE PROPORTIONS OF THE METAL ALKYL COMPOUND MAY RANGE BY VOLUME FROM ABOUT 1% TO ABOUT 99%, THE REMAINDER BEING THE ORGANO-SILANE COMPOUND.

    摘要: Leaks in pipelines, conduits, tanks, vessels and the like are sealed by introducing ammonia gas under pressure into such equipment which will escape through any existing leaks and react with an aqueous metal salt solution supplied at the external site of the leak to form a solid reaction product which seals the leak. Ammonia gas admixed with carbon dioxide gas may also be used in this process to produce complex solid reaction products for sealing leaks.
