Abstract
A system for field internally coating a pipe joint comprising a polymer application unit, which has a first cart configured to selectively advance inside a pipe; a first and a second tank configured to contain a first and a second polymer component respectively; a mixer to mix the first and the second component; a first and a second pump to feed the first and the second component respectively from the first and the second tank to the mixer, an applicator to apply the polymer to the pipe; and a conduit comprising a free end configured to be placed near the applicator to feed the polymer from the mixer to the applicator.

A system comprising:
- a polymer application unit comprising:
- a first cart configured to selectively advance inside a pipe in a direction parallel to a longitudinal axis of the pipe;
- a first tank configured to contain a first polymer component;
- a second tank configured to contain a second polymer component;
- a mixer configured to mix the first polymer component and the second polymer component to form a polymer;
- a first pump configured to feed the first polymer component from the first tank to the mixer;
- a second pump configured to feed the second polymer component from the second tank to the mixer;
- an applicator configured to apply the polymer to the pipe;
- a conduit comprising a free end configured to be placed within a designated distance of the applicator to feed the polymer from the mixer to the applicator;
- and
- a second cart configured to slide along the first cart in the direction parallel to the longitudinal axis of the pipe to move each of the mixer, the applicator and the conduit with respect to the first cart.
