What are the methods of cleaning titanium tubes?

Titanium tubes are light in weight, high in strength and superior in mechanical properties. Titanium tubes are widely used in heat exchange equipment, such as shell and tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and pipelines. Many nuclear power industries use titanium tubes as standard tubes for their units. Huayu titanium tube manufacturer took us to see what are the methods of cleaning titanium heat exchanger tubing?

1. Alkaline cleaning: Soak the titanium tube with 3-5% sodium hydroxide analytically pure solution for 30-60 minutes at a temperature of about 40 degrees. Good in an ultrasonic cleaner. After immersion, flush the inside and outside with filtered deionized water or water for injection until neutral, and measure the conductivity. Blow dry with pure air ≥ 0.4Mpa pressure.

2. Pickling: Soak the Seamless Titanium Tube Grade 2 in 5% nitric acid solution for more than 8 hours at a temperature of 40 degrees. Good in an ultrasonic cleaner. After immersion, flush the inside and outside with filtered deionized water or water for injection until neutral, and measure the conductivity. Blow dry with pure air ≥ 0.4Mpa pressure.

3. The above two methods can be used alone or in conjunction with each other. If conditions permit, it can be combined with an ultrasonic cleaning machine for good results.

4. Organic matter pollution can be cleaned in combination with surfactants, and the debris pollution system combined with enzyme cleaning has a good effect.
