Product Description

Pre-Stressed Vacuum Insulated Tubing/Casing

Product Explanation:

1.Reduces the heat loss, ensures the steam quality being injected into the oil formation as well as the depth of steam injection can be increased.

2.Minimizes heat stress on well casing and cement mantle, protect the casing from damage by high temperature.

3.During oil production it will provide superior insulation and greatly reduce the loss of heat energy

Product Features:

1. The pre-stress will compensate the tubing expansion caused by temperature difference between the inner and the outer tubes so as to ensure reliable operation under high temp.

2. Gas absorbing materials are packed inside the annulus to clean up harmful gases and maintain good insulating property whilst in service.
