Inner coated tube
Ferroco tube
Ferric oxyhydroxide coating tube
- Protection film on the inside surface of tube which is composed of iron oxyhydroxide before water passing, it would get high resistance for corrosion as initial protection film.
- No swell of film by electric corrosion protection so that the customer is able to adopt this Ferroco tube with the same condition as existing tube.
- he customer would not need to inject high density Fe-ion in order to make a initial film after re-tubing. Keep high heat transfer effiency of equipment.
- Specification・Manufacturable range
- Components of film
- iron oxyhydroxide
- Thickness of film
- Average 5～15㎛
- Expanding section
- Both tube-end appox.50㎜(Reference) shall be no coating(general）
- ※Reference length：Expanding section appox.+5～10㎜
- ※Entire length(0㎜)～appox.50㎜ ※less than 50mm shall be available
- ※Please contact us if you require more than appox.50㎜～120㎜(Max)
- Size
- Outer diameter：φ16㎜～φ38㎜（Inside diameter φ13㎜ or more)length：
φ16㎜ or more～φ25㎜：18m or less
φ25㎜ or more～φ30㎜：23m or less
φ35㎜：18m or less
φ38㎜：15m or less
Attention to the operation
lease pay attention to followings same as forming the initial film by Fe injection.Keep the velocity as normal from initial water passing because sea creatures would stick to the inner surface of the tube with slow velocity and be harmful for protection film.
Leaving the tube wetted with seawater shall be the cause of corrosion, degradation of the film. When it needs to leave the tube for long period, please clean the inside of the tube up by fresh water then enough dry.
Do not excessive inject chlorine.

KC tube
Resin coating tube
- Resin coating has high corrosion resistance against the corosion caused by temporarilly polluting water.
- It has excellent durability for physically cleaning such as Spongie ball cleaning, so that this item is suitable for the water need to rempve some deposits.
- About 5% Decrease of coefficient of overall heat transmission in Condenser's aluminum brass tube with resin coating, which is excellent performance.
It also prevents the decreasing of coefficient of overall heat transmission as it reduces a pollution by corrosion product during use.
- Specification・Manufacturable range
- Components of film
- Epoxy resin
- Thickness of film
- Average 5～15㎛
- Expanding section

- 寸法
- Outer diameter：φ16㎜～φ38㎜（Inside diameter φ13㎜ or more)length：
φ16㎜ or more～φ25㎜：18m or less
φ25㎜ or more～φ30㎜：23m or less
φ35㎜：18m or less
φ38㎜：15m or less
Attention to the operation
If KC tube was ued with Cathodic protection, it might cause swell of film at the tube end. KC coating has good adhesion so that it would decrease the swell, however,it is strongly recomended to control the electric potential as -500～550mV SCE at the vicinity of tubesheet when using potentiostat.
Prevent inflow of foreign substance since sharp matter shall scratch the protection film.
