Basic Principles Of Grooved Mechanical Joints

SUMMARY

• A grooved pipe joint is comprised of four main • There are two basic coupling styles:
elements: grooved pipe, gasket, coupling housing, • Flexible – allows for controlled linear and
and track head bolts and nuts
angular movement, which accommodates
• Grooves are rolled or cut into the ends pipeline deflection, as well as thermal
of the pipe expansion and contraction
• An elastomer gasket is then placed
on the pipe ends • Rigid – resists torsional and flexural loads,
as well as provides a joint that mirrors the
• Ductile iron housings, assembled with track
head bolts and nuts, surround the gasket same supporting requirement of a welded joint
and engage into the grooves See pg. 12
• The end result is a self-restraining pipe joint, • The “Victory Joint” was patented in 1919, by
designed to last the life of a piping system
The Victory Pipe Joint Company (now known
See pg. 2
as Victaulic) as a way to join pipe with bolted
mechanical grooved couplings
• The two types of grooves are: See pg.18

• Roll – cold formed process where no material
is removed from the pipe • Grooved mechanical piping systems offer a variety

• Cut – created by removing pipe material of joining solutions (metal, plastics, coating / linings)
See pg. 3 See pg. 19

• The critical dimensions of a groove are: • A few of the markets and industries that benefit
from grooved mechanical solutions include:
• A – Gasket Seating Area commercial / HVAC, fire protection, power
• B – Groove Width generation, marine, biofuels, mining, water /
• C – Groove Diameter wastewater, and oil, gas and chemical
• D – Groove Depth
• T – Wall Thickness See pg. 20
• F – Pipe Flare
• OD – Outside Diameter
See pg. 6
