The completion pressure test of the light tower in the air separation equipment is a key link to ensure the safe and stable operation of the equipment. Its core purpose is to verify the structural strength and sealing, ensure process safety, guarantee product quality and efficiency, extend equipment life, and meet acceptance and compliance requirements.
Strength testing: By injecting high-pressure gas (such as nitrogen) or liquid into the tower, simulating the pressure conditions during actual operation, the pressure bearing capacity of the tower body, connecting pipes, flanges and other components is tested to ensure that they will not undergo permanent deformation or rupture under the design pressure.
Sealing test: Check for leaks at the connections of the tower body (such as welds, flange gaskets, manhole seals, etc.) to prevent gas or liquid leaks during operation that may cause safety accidents or a decrease in product purity.
The pressure test of the dehydration tower is a bridge connecting equipment manufacturing and safe operation. Through systematic testing, hidden dangers are eliminated, laying the foundation for the long-term, efficient, and safe operation of the air separation unit.

1 pay attention to the direction of the arrow on the valve and the process requirements of the media flow direction, in order to avoid installation errors. 2 The pipeline connected with the valve should be thoroughly cleared of dirt, dust and other foreign mechanical impurities before installation. Prevent damage of the sealing surface of the valve. 3 The cold valve on the cold box should be installed at the same time as the corresponding brack...
