||Test Method for Pipe Thread Sealants
Pipe thread sealants are used in various types of machinery and
engines that contain tubes and piping to move fluid through a
system. These sealants hold pipe plugs in place and strengthen
as well as seal piping.
D 6396, Standard Test Method for Testing of Pipe Thread Sealants on
Pipe Tees, defines procedures used to assemble, evaluate, and
test pipe thread sealants useful for machinery and engine manufacturers,
sealant and adhesive suppliers, and design engineers.
The test method offers manufacturers and suppliers a means to
determine and quantify strength of the thread sealant and resistance
to aggressive environments, says Tech Service Manager Dennis
Damico, Lord Corporation, Erie, Pa., who participated in the development
of the test method. Standard D 6396 tests:
--Cure speed versus temperature;
--Solvent and steam resistance;
--Hot strength; and
--Specimen preparation for high pressure testing.
Engineers, users, and suppliers of pipe thread sealants developed
the test method as a task group of ASTM Subcommittee D14.80 on
Metal Bonding Adhesives in Committee D14 on Adhesives.
