Abstract: Ice blockage will easily occur when transporting natural gas at low temperature, which threatens the safe running of gas pipeline. Aiming at eliminating ice blockage of equipments in compressor station, the feasibility study to control ice blockage is made by a freezing test. In the test, contact angle tester and scanning electron microscope are in position. Based on theoretical analysis, surface modifying method to vary the chemical property of base metal of steel for the equipments in compressor station is reviewed. Researches indicate that proper surface treatment and silane modification on the base metal can form a layer of hydrophobic or super-hydrophobic nanometer film on the steel surface, which increases the contact angle of water on its surface with water holding free on steel surface. And moreover, the freezing test also certifies that the modified surface of steel can prolong the freezing time after hydrophobic and super-hydrophobic modification, the kernelled work of water to ice is greatly increased with the increase of contact angle. The bigger the contact angle is, the greater the kernelling work is, and the more difficult the water to ice is. The test and theory results show that hydrophobic modification of steel surface can deal with the ice blockage of equipments in compressor station with an available field application.
