Fast Facts

 
 

It is crucial to know your well before choosing a thermoplastic liner. Selecting the proper thermoplastic for your well environment and well temperature will make a difference. Western Falcon currently offers four different thermoplastic liners with each having a different temperature range from 160°F to 500°F. Make sure you check your specific well conditions and choose the proper liner for the highest temperature you expect.

Thermoplastic liners can be mechanically damaged. Please visually inspect rod string and boxes to make sure they are free from sharp edges or corrosion damage.

Thermoplastic lined tubular create an ID restriction, please refer to dimension chart and drift sizes.

Thermoplastic liners are inert to most chemicals and acids.

Minimum API Torque should be followed when making up connections. No special position makeup.

Drifting of connections after makeup is strongly suggested.

Thermoplastic liners can be used in wells that are highly deviated, dog legged, or corkscrewed.

Thermoplastic liners can be used in horizontal wells where the pump is set below kick-off point.

Rod guides are not recommended in rod wells.

The unique mechanical bonding process allows the ability to line used tubing. Please keep in mind that thermoplastics do not add strength to the steel. You need to be comfortable with the structural integrity of the steel tubing before lining and installation. Remember, liners protect the ID of your tubular. If you start with yellow banded pipe, then in 10 years, you will still have yellow band pipe unless you have an environment that deteriorates the OD of the steel.

Hot oiling or hot watering can be performed on thermoplastics as long as the temperature does not exceed the temperature limit of the liner installed. A minimum safety margin of -10°F is recommended because of the potential for error in field temperature measurements and uneven heating of fluids.
