This is chemical setting Furan based chemical resistant mortar which is combination of Liquid and Powder, when mixed in proper proportion from workable mortar which after setting and curing give of liquid and give black highly cross linked composites. Furan When set and cured is resistant to highly corrosive acids, alkalis and to powerful organic solvents such as ketones, Aromatic and Chlorinated solvents. It has extreme resistant to Acidic & alkalis, Salts, Greases and Detergents. It resists to Organic & Inorganic acids at their boiling temperature. It is suitable against mild chlorine Gas (dry) phosphorous trichloride, pyridine at room temperature. Furan is especially useful where resistance to mixed media such as aqueous acids /alkalis and organic solvents is needed in chemical plant process and waste streams. Carbon filled Furan is used against corrosive effect of hydrofluoric acid & its salts. PREPARATION OF FURANE MORTAR : Mortar consist of Furan solution and Furan powder. The average mixing ratio necessary to obtain mortar with good working consistency is 1 part by weight Solution & 3 part by weight powder. The ratio will vary slightly depending on temperature and working conditions.Stir the liquid thoroughly before using. Place liquid in a suitable shallow mixing pan. Add powder by weight in the solution mix thoroughly and rapidly until all lumps are dispersed and the mortar is completely homogenous. Spread out the mortar in a thin layer, not more than ¾ thick, to dissipate the heat of reaction and lengthen the working life. Batch size can be varied depending upon the temperature and the speed with which the masons are working. Very large batches will become stiff quite rapidly. Make sure that all the Furan Motrar is used from the pan before another batch is mixed.When working at temperature above 40 C, very small batches not more than 2 Kgs, should be prepared. When working at temperature below 15C the liquid should be kept warm.
* PHOSCAST Phoscast : Phosphate Bonded Castables * PURPOSE customers using FBC boilers (Particularly underbed feed FBC boilers) for the protection of inbed coils against erosion potential by applying highly abrasive resistant refractory on inbed coils above fuel feed system. BACKGROUND * Two of such actions are providing special alloy studs on inbed coils and applying highly abrasive resistant refractory on the outer bottom loops of inbed Coils which are above the fuel feed nozzles. * GANESHAS has taken number of approaches to identify the key factors affecting erosion rates with an objective to enhance the life of inbed tubes as well as implementing the corrective action to reduce the erosion rates. Phosphate coatings are often used to protect steel parts against rusting and other types of corrosion * Erosion of inbed coils in fluid bed combustor is unavoidable phenomenon however the rate of metal wastage and thus the life of tubes depends on various factors like ash & fuel properties, design of Combustor / feeding system, flue gas velocities operating conditions etc. It has been also observed that maximum erosion prone inbed coils are those which come above fuel feed nozzles and an area of approximately 1 to 1.5 mts around fuel feed systems are badly affected. APPLICATION Phoscast-90 XR can be applied by ramming with wooden mallet having adequately large head @" dia x 5" length x 10â?? Jong handle). The desired lining or repair thickness is built up in several courses while ramming the mass to uniform thickness. Phoscast refractory should never be trawled to obtain smooth surface; ramming only should finish surface. Any excess mass is to be sliced off with trowel edge and then finished by ramming again for bed coil. Tube application of AFBC boiler, the material pasty mass should be finger pressed into the studs of the tube with maximum force. Finish should be given by pressing the hand palm against material applied, using surgical type thin rubber hand gloves.
The main pipes used in the offshore Oil and Gas Industry are Duplex 2205 (22% Chromium, 5% Nickel) and 2507 (25% Chromium, 7% Nickel); and Super Duplex 2507 which has higher corrosion resistance (ANSI) and the American Soc. of Mechanical Engineers (ASME) specify wall-thickness requirements.
