Mesh applications in candle filter and leaf discs

Candle filters

The metal mesh filters are made in both cylindrical and square shapes for standard industrial designs and are custom made to fit in the specific housing. These are made in sintered metal fiber and woven wire mesh.

The designs include heavy duty mesh that offer sufficient strength to withstand high differential pressures about 120 bar in fact higher too if needed. Low carbon steels are widely used to offer supreme corrosion resistance. The thread coatings are offered when essential to prevent the galling of material.

Sufficient care is taken to confirm that the design is free from stagnant flow areas that could slow down the polymer, cross-link and affect. The mesh are offered with internal volume reducers at the closed end to support in it and usually have flow divert characteristics to offer good flow distribution over the mesh when the polymer enters.

In the various designs, the open end can of the candle is made to sink into the tubesheet to confirm extending the filter medium.

For several applications, the Hastelloy mesh pleated candles are used for extended surface area and prolong active life. For few polymers such as polypropylene, it is discovered that the large viscosities refer that there is nominal flow among the pleats and on-stream life is not significantly more than a plain cylindrical candle. The plain candles are preferred in this media.

Uses:

a.       Polyester bottle

b.      Polyester fibre

c.       Cellulose acetate fibre

d.      Nylon fibre

Advantages and characteristics

a.       Sturdiness for cleaning and frequent use

b.      Prolong life

c.       Service at the high temperature media

d.      Supreme carbon resistance

e.      Good filtration area for pleated candle design

The candle mesh filters are customizable to fit any specific housing. They are made in sintered metal fibre and woven wire mesh. The filtration ratings vary from 3 to 100 microns, these are normally delivered with an external guard t secure the media and to permit reverse flow while cleaning. The candle mesh is easily cleanable with advanced technology. The candles are developed with separable hardware fitting and replaceable media to offer lower service costs. They are fit for any industrial designs and can be customized for specific housing.

Leaf discs

Leaf disc and solid plate filters are made for critical hot melt polymer filtration applications to achieve great gel control by offering smooth flow and hence higher gel retention on the filter.

Additionally to offer a great range of filter media, the leaf disc filters provide the great design characteristics ensuring low pressure drops to offer longer stream life. The firm structure permits several cleaning cycles hence decrease overall life costs.

With our extensive experience and great range of filer media, the application and design engineers can custom design adequate filtration products for every product and process, it includes support during design process to attain active performance for the long terms.

We characterize our media and elements service by evaluating them through flow tests, microscopy, chemical test, tensile test, metallography and quantification of polymer contaminant with image analysis.
