High flux pipe is specifically designed to enhance heat transfer coefficient. A thin, porous metal layer is bonded metallurgically to the heat transfer surface. This pore make liquid produce a large number of bubbles at low superheat, which enhance heat transfer. At the same time, porous structure formed many boiling centre, the film boiling changes to nucleate boiling. So boiling side heat transfer coefficients of 10-30 times that of bare tubes can be achieved, resulting in an overall heat transfer improvement of 2-4 times that of bare pipes.

Fe3al filter element
Product material and specifications
1. This filter element is formed by isostatic pressure and vacuum sinter. In order to get high filtration precision and permeability at the same time, composite structure is designed, one is supporting layer with high intensity, big pore and low resistance drop. The other is membrane layer with small pore and low resistance drop.
2. Two layers are all fe3al, so there is good bond strength after vacuum sinter.
3. Maximum length is 1500mm, a longer one can get with weld.
4. Widely used in coal chemical industry because of its good sulfur corrosion resistance
Main performance indicators
1. Filtering accuracy 0.3-3m
2. Heat resistance: it can be used under 700 for long term:
3. Corrosion resistance: the product has excellent high temperature oxidation resistance and resistance to sulfur corrosion.

Shale shaker screen is used in slurry, gas&oil field and for filter as a filter element. there are many kinds of screen, such as derrick, brandt, swaco and so on
The mesh count is very important for hte fine mesh screen. Our screen mesh could up to 325 meshes. And we can produce the screens with one or more layers.
Type: hook strips flat, frame, soft hook strips, flat screen, pyramid screen and so on.
