ميزة أنبوب الفولاذ المقاوم للصدأ في المكثف

Stainless steel tube condenser is superior to copper tube condenser as follows:

Good erosion resistance. It can resist the impact of steam and water droplets at high speed. As early as the mid-1850s, the United States began to arrange stainless steel pipes around the tube bundle.

Good resistance to ammonia corrosion. Ammonia media can cause stress corrosion cracks in copper pipes, and can also lead to condensate corrosion, which is called ammonia corrosion. The use of stainless steel pipes does not require other anti-corrosion measures.

Excellent resistance to water side impact corrosion and phobic corrosion. The pipe end may not need ferrous sulfate protection.

After adopting the stainless steel tube condenser, the unit can adopt the copper-free tube subsystem, and the PH value can be increased to reduce the corrosion rate.

The condenser with stainless steel tube can achieve no leakage of the condenser like the titanium tube condenser, which can save the tube replacement and maintenance work of the copper tube condenser. Its service life is 3 times that of the copper tube. ～4 times, reaching the same life span of 30-40 years as the main engine.

The cooling water speed of the stainless steel tube condenser can be increased to 2.3m/s, up to 3.5m/s, which not only improves the total heat transfer coefficient, but also enables the impurities in the cooling tube to be taken away. The surface of the stainless steel pipe is relatively shiny, not easy to scale, and its cleaning coefficient can be increased to 0.9.

The cooling water of the stainless steel tube condenser can be adapted to dissolved solids ≤ 2000mg.

Because stainless steel has higher strength and elastic modulus than copper, it has good seismic performance. Therefore, the distance between pipe partitions of the same diameter can be greater than that of copper pipes. And can use seam thin-wall welded pipe. Although stainless steel pipes are more expensive than copper pipes, the weight of pipes with the same heat transfer area will be about half lighter than copper pipes, so the total price of condenser pipes is almost similar.
