Sealing Concepts

Teekay Couplings are available in two configurations: Axilock and Axiflex

Teekay Pipe Couplings allow pipes to be joined withoud the need for flanging, grooving,

threading or welding. By simply butting two pipes together and connecting with a Teekay

Pipe Coupling, space, weight, time and cost savings are achieved with every installation.

Each coupling (whether Axilock or Axiflex) consists of a casing, a gasket and a lockpart. The

purpose of the casing is to house the gasket and to press it onto the pipe surface when the

lockpart is closed. The lockpart is designt to pull the two ends of the casing together

circumferentially around the pipe. In order to achieve this, the coupling is labelled clearly

with a torque which ensures that the gasket is compressed sufficiently against the pipe

sureface.

Part 1 - Axilock

The Axilock has two anchor rings which are placed adjacent to (figure. 4/8), but separate from the

sealing mechanism.(figure 3/8).

As the Lockpart is tightened the sealing lips are pressed against the pipe sureface to from

a seal. At the same time two anchor rings penetrate the rubber, bite into the two pipes and

prevent them from pulling apart., whether bay external loading or internal pressure. The end

seal (figure 2/8) is also pressed against the pipe sureface, which protects both the anchor ring and the

section of the pipe where the anchor rings have bitten, from any possible external corrosion.
