Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings.
According to the application:
1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc.
2. changing the direction of the pipe: bends, bends.
3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe.
4. pipe fittings with additional piping branches: three links, four links.
5. pipe fittings for pipe sealing: gasket, raw material belt, thread, flange blind plate, pipe plug, blind plate, head, welding plug.
6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc.
According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings
According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings.
Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.
Pulse Jet Bag Filter
The Bag House/Bag Filter is generic name of Air Pollution Control Equipment. It is designed around the use of engineered fabric, filter tubes, envelopes or cartridges in capturing dust, separating dust or filtration process. AIL provides reliable and highly efficient Bag Filters and Bag House systems.
The dust laden gas enters through inlet nozzle and spreads all over the entire cross section of the bag filter. The gas moves up & passes through the bags, enters the clean air plenum through the top open end of the bags. During the passage of the gases through the fabric, the dust is retained on the outside surface of the bags. As the filtration proceeds the thickness of the dust layer on the fabric surface increases resulting in increase in pressure drop across the fabric. This necessitates the cleaning of the bags. Since the air flow is from outside to inside, the bags tend to collapse and are held by the wire cages, whose shape they acquire. The compressed air passing through the solenoid valves injects air at very high velocity for a short duration. This produces a shock wave causing the bag to expand and dislodging the dust cake which falls into the hopper. This unit is generally meant to operate with a pressure differential of 100-125 mmWG.
Cyclone Dust Collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dustand other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system. It is distinguished from air purifiers, which use disposable filters to remove dust.
Multiple-cyclone separators consist of a number of small-diameter cyclones, operating in parallel and having a common gas inlet and outlet, as shown in the figure, and operate on the same principle as single cyclone separatorsâ??creating an outer downward vortex and an ascending inner vortex.
Multiple-cyclone separators remove more dust than single cyclone separators because the individual cyclones have a greater length and smaller diameter. The longer length provides longer residence time while the smaller diameter creates greater centrifugal force. These two factors result in better separation of dust particulates. The pressure drop of multiple-cyclone separators collectors is higher than that of single-cyclone separators, requiring more energy to clean the same amount of air. A single-chamber cyclone separator of the same volume is more economical, but doesn't remove as much dust.
Cyclone separators are found in all types of power and industrial applications, including pulp and paper plants, cement plants, steel mills, petroleum coke plants, metallurgical plants, saw mills and other kinds of facilities that process dust.
* 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.
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.
