Compression-sleeve couplings such as the Dresser coupling (see fig. below)
and the Victualic coupling (see fig. below)
are widely used for above- and below-ground services, both with cast-iron and steel pipe. Consult the manufacturers’ catalogs for more information.
These joints require very little installation labor and as such result in an economical overall installation. Advantages include the ability to absorb a limited amount of thermal expansion and angular misalignment and the ability to join dissimilar piping materials, even if their outside diameters are slightly different.
Disadvantages include the use of rubber or other elastomer seals, which limits their high-temperature application, and the need for a separate external thrust-resisting system at all turns and deadends to keep the line from separating under pressure. Compression joints are frequently used for temporary piping systems or systems that must be dismantled frequently for maintenance. When equipped with the proper gaskets and seals, they may be used for piping systems containing air, other gases, water, and oil; in both aboveground and underground service. Small-diameter compression fittings with all-metal sleeves may be used at elevated temperatures and pressures, when permitted by the rules and requirements of the applicable code. They are common in instrument and control tubing installations and other applications where high seal integrity and easy assembly and disassembly are desirable attributes.

Subject: [MW:1993] sleeve coupling joint
can anybody tell me about the use of sleeve coupling joint in piping?
means what is the advantage of using sleeve coupling joint?
