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 2 - Axiflex

The Axiflec is a high performance coupling that allows generous pipe angulation and

expansion / contraction.

The Teekay Axiflex joins pipes that are already anchored. In this instance the pipeline

forces do not have to be contained by the couplings.

Available in sizes up to 4.2m in diameter.

The coupling can be placed over the pipe ends or supplied in a wraparound version

The Axiflex has two thick sealing lips which allow for pipe expansion and contraction

(Abb. 3/8).

The sealing lips press against the pipe surface and form lip seals. The lip seals are designed

to resist the internal pressure in the pipes. As the pressure increases, the lip seals swell to

seal more tightly against the pipe sureface.(Abb. 4/8).
