Raw material that we use has good mechanical strength, high environmental strength , crack resistance, material stability over a wide range of temperate and cycle time. The resin will have a fast and broad cure cycle, provide shrinkage from part to part and exhibit good wrap resistance.Additives:The LLDPE granules in its original form cannot be process for tank manufacturing in rotational molding. It has to be converted in to color granules. This coloring is takes place with addition of color concentrate during extrusion process. Base raw material is LD. Loading of Colorant If black the percentage of carbon (at least 50%). If Milky white then percentage of titanium. 'Carbon' in black master batch act UV stabilizer therefore it will be added to the level of 2 to 3 % of LLDPE. Other wise tank life during expose to sunlight will be less and tank may develop crack.Advantages of Rotational Molding: One part construction: Virtually stress free parts totally closed or opening. Uniform wall thickness, Metal inserts as integral parts. Product from this process can offer excellent load bearing properties and resistance to stress cracking and corrosion.   PVC Pipes http://www.precisionstoragevessel.net/pvc-pipes.htm http://www.precisionstoragevessel.net/pvc-pipes.htm Wed, 03 Apr 2019 00:00:00 +0530 PVC Pressure pipes as manufactured as per IS 4985-2000 , DIN 8062 standards for irrigation sewage water and plumbing pipes with Sizes from 20 mm to 110 mm. We have independent lab facility with all testing instrument to test the pipe manufactured.Our Process ; In first stage of the extruder the powder is subjected to relatively high mechanical forces which are intended to reduce the pvc grains clusters .The rate at which this process occurs depends upon the temperature & lubricant balance. The internal lubricant will tend to encourage the breakup of the grain by weakening the bonds between the primary particlesThe external lubricant reduces the frictional heat & therefore reduces this mechanism. As the material passes further down the extruder barrel the temperature increases which reduces the bond strength between the molecules within the primary particles. Ultimately a homogeneous mass of molten plastics form.Unique features of our pipes are Non Toxic, Smooth inside bore, Non biodegradable, flexible.    Wall thickness exceeds the requirements of related standards. Air Separators http://www.precisionstoragevessel.net/air-separators.htm http://www.precisionstoragevessel.net/air-separators.htm Wed, 03 Apr 2019 00:00:00 +0530 Material of Construction : Carbon Steel – Flanged to Class 150/PN16/ PN25 All steel body Stainless steel strainer Advantages : Elimination of air from closed circulation system Tangential style Low velocity vortex Avoid inefficient pump operation. Low pressure drop across the separators Benefits : Recover air perfectly Optimum pump operation Prevent pump cavitation. “Precision” tangential air separators are manufactured in state of the art modern facility with automatic machines Principle :Precision Tangential air separators removes air from the system through centrifugal action, with a combination of centrifugal force and with reduction of velocity. This makes the air, force water towards the outlet connection, where the separated air moves to the low velocity center. Air is removed from the system through air vent.Operating Conditions : Standard working pressure : 10 bar Standard Working Temperature – 177°C Can supply for pressure up to 30 bar Blowdown Vessels http://www.precisionstoragevessel.net/blowdown-vessels.htm http://www.precisionstoragevessel.net/blowdown-vessels.htm Wed, 03 Apr 2019 00:00:00 +0530 Steam boilers must be blow down at regular intervals to resolve some of the suspended and dissolved solids formed during the course production of steam. These undissolved solids in the boiler water can give rise to foaming and scaling of the boiler tubes and shell. Selection of a blowdown vessel depends on the flow rate and the proportion of flash steam released. Blowdown vessels are manufactured in Carbon steel plates. Air & Dirt Separators http://www.precisionstoragevessel.net/air-dirt-separators.htm http://www.precisionstoragevessel.net/air-dirt-separators.htm Wed, 03 Apr 2019 00:00:00 +0530 Precision Air and Dirt Separator are designed to eliminate air and separate debris associated with any hydronic system. In removable type High Velocity air and dirt separator, a removable flanged type end cover is installed so that easy access for coalescing medium and dirt removal. Non removal type high velocity air and dirt separator are also manufactured.

A tap is fitted on top of the removable cover (in removable type) and in body for non removable type to facilitate system fast fill and removal of floating impurities and air trapped within the air separator.ApplicationPrecision Air and Dirt Separator removes entrained air bubbles and dirt particles in the system. Small Air bubble coalesce and form larger air bubbles which rise to the top of the vessel and vented through the air vent. Dirt particles that are collected at the bottom of the separator can be removed through the blow down valve .In case of coalescing medium to be cleaned then top removable cover to be removed for access. Precision air & dirt separators provide higher efficiency with reduced pressure drops so a smaller pump can be used to achieve maximum efficiency.PALL Ring TechnologyPrecision air and dirt separator use proven PALL ring technology. By using Pall Ring technology micro bubbles as small as 18 microns, and dirt particles of 35 microns can be removed. It removes air from place where air vent cannot be installed and also it removes and separates solid particles. Pall Rings are kept in a stainless steel basket which can be removed from the top flange of removable type air and dirt separator. Pall rings are made of Stainless steel 304 material. Air bubbles are separated by the pall ring through coalescene process where dirt particles are caught and drifted to the bottom of the tank, further removed through blowdown valve.Typical SpecificationsFurnish and install, as shown on plans, a removable / non removable type Air and Dirt separator. The unit shall have flanged inlet and outlet connections to the vessel. A vent connection shall be fitted to the top of the vessel to enable installation of Airvent. Air and Dirt separators shall have all steel body construction designed fabricated and stamped as per ASME Section VIII Div I with a working pressure of 10 bar. Each Air & Dirt Separator to be fitted with a blow off tap to remove the air trapped within the separator.
