For decades, TAM International has manufactured the
premier Port Collar for the Oil and Gas Industry. TAM
Port Collars provide a selective communication path
from inside the casing to the annulus. They engage,
open, close and release with minimal work string
movement. With sizes available from 2 7/8” through 26”,
their proven track record is attributed to solid design and F ea tures:
precision machining. TAM Port Collars operate with a simple (up/down or
rotate) movement of the inner string and Combo Tool.
Spring-loaded Dogs latch onto the
Port Collar’s inner sleeve profile. Special features such as Metal-to-Metal seals, a locking
closed mechanism, slim line versions, premium threads,
and NO Rotate to Release versions are available.
Metal-to-Metal seals are useful in corrosive
environments and in casing strings where casing
integrity or a gas-tight environment is critical.
In premium Port Collars, Metal-to-Metal seals are
standard, and lock pins are used to prevent the sleeve
