3　Lining Design

3.1　General Requirements

3.1.1　Lining structure，lining materials and application requirements shall be determined based on the process，operating conditions，operating cases at various locations，effect on lining due to expansion of metal components，environment protection，energy conservation and economic considerations.

3.1.2　When the temperature of the exterior metal wall is determined，it shall not cause dew point corrosion on the metal wall.

3.1.3　More anchors shall be erected at the locations such as equipment transition sections，equipment openings，special positions and irregular structural positions.

3.1.4　Gas barrier rings should be provided for the reactor-regenerator system equipment applied with double layer heat-insulating and abrasion-resistant lining with hexmesh at an interval of 1500 to 2000mm at axial direction.

3.1.5　Details shall be provided for the lining structure used at special locations and irregular structural locations.
