Goel's TECHNICAL INFORMATION

Laboratory works require apparatus made in a Borosilicate 3.3 expansion glass which offers maximum inertness to widest range of chemical substances, withstand thermal shock, high temperature without deforming and resilient enough to withstand the normal laboratory handling, washing and sterilizing processes.

Borosilicate glass represents unmatched standardized glass for construction of Laboratory Glasswares. Its steadly growing use is due to many advantages over conventional materials.

Outstanding corrosion resistance Smooth pore and surface. Transparency Catalytic, inertness No effect on taste and odour Physiological inertness

Borosilicate glass is chosen for its unique chemical and physical properties. Borosilicate glass can be considered as being composed of oxides. Silica (SiO2 ), boric oxide (B2O3 ) and phosphorous pentaoxide (P2O5 ) are chief glass form oxides. Soda (Na2O), Lime ( CaO ), Alumina (Al2O3 ) Potash (K2O) Magnesia (MgO) and lead oxide (PbO) are the principle modifiers/fluxes.

CHEMICAL COMPOSITION The composition of borosilicate glass used has following approximate composition. SiO2 - 80.6 %B2 O3 - 12.5% Na2O - 4.5 %Al2 O3 - 2.2 %

RESISTANCE TO CHEMICALS Borosilicate glass is inert to almost all materials except hydrofluoric acid (HF) phosphoric acid (H3PO4) and hot strong caustic solutions. Of these, Hydrofluoric acid has the most serious effect, even when it is present in PPM (parts per million) in solutions, Whereas phosphoric acid and caustic solutions cause no problems when cold but at elevated temperature corrosion occurs. In case of caustic solutions upto 30% concentration can be handled safely at ambient temperature.

Under actual operating conditions, the effect of turbulance, and traces of other chemicals in the solution may increase or decrease the rate of attack. So it is not possible to give exact figures for corrosion by caustic solutions.

THERMAL PROPERTIES Linear coefficient of thermal expansion the coefficient of thermal expansion of borosilicate glass over the temperature 0-300 OC is 33 x 10-7 / OC. This is very low when compared with other glasses and metals. That is why borosilicate glass is often called low expansion borosilicate glass.

SPECIFIC HEAT

Specific heat between 25OC and 300 C is average to be 0.233Kcal/Kg C.

THERMAL CONDUCTIVITY

Thermal conductivity is 1.0 Kcal/hr. m C over the permissible operating temperature range.

ANNEALING

Annealing of glass is the process where the glass is heated and kept for a defined period of time to relieve internal stresses. Careful cooling under controlled conditions is essential to ensure that no stresses are reintroduced by chilling/cooling.

MECHANICAL PROPERTIES

The lack of ductility of glass prevents the equalization of stresses at local irregularities or flaws and the breakage strength varies considerably about a mean value. This latter is found to occur at a tensile strength of about 700kgs/cm. In order to allow for the spread of breaking stress, a large factor of safety is applied when determining the wall thickness requirement to allow operation up to specified limit of working pressure.

OPTICAL PROPERTIES

Borosilicate glass shows no appreciable absorption in the visible region of spectrum and therefore appears clear and colorless. In photo chemical process the transparency of ultra violet is of particular importance. It follows from the transmittance of material in UV region that photochemical reactions such as chlorination & sulpho -chlorination can be performed in it.

Goel’s Condenser

We at GOEL manufactures and supplies Condensers up to 24inches.

Condensers are used for condensation of vapors and cooling of liquids. Condensers are made by fusing number of parallel coils in a glass shell. Coils are made in different diameters using tubes of different bores.

The average co-efficient of heat transfer in coil condenser

is considered as-

Condensation 200 - 270 Kcal/m ,hr, C appx.

Cooling 100 - 150 Kcal/m ,hr, C appx.

Below table shows the detail dimensions of different size condensor:

Precautions to be taken in use of condensers

- Vapors should be passed through shell only.

- Maximum pressure of coolant should be 2.7 bars.

- Adequate flow of coolant should be used.

- Steam should not be used in coils.

- Coolant should not be heated to boiling point.

- Coolant control valve should be turned slowly.

- Coolant should be allowed to drain freely.

- Brine can be used in coils in a closed circuit.

- Water main should be connected with flexible hose.

- Ensure no freezing of water remaining in the coils.

- Condensers should be mounted vertically only.

- Condensers can be mounted in series to provide larger surface area.

METHODS OF USE

Vapors from bottom

This method is simple to install over a reactor. However this results in condensate returning substantially at its condensing temperature. In this method care must be taken that condensate is not excessive that it can lead to "logging" the coils and create back pressure in the system. Generally a reflux divider is used below the condenser to take out the distillate.

Vapors from top

This method produces a cool condensate using the entire cooling surface area. This method should be used where the condensate can lead to "logging" of coils.

Jacketted Vessels

We at GOEL understand the requirement and fulfill the needs by supplying the best of ours to consumers.

Jacketed Vessel is used for special applications. A cylindrical vessel is supplied with jacket of glass for heating and cooling purpose. Jacket is sealed to the vessel with Viton ‘O’ sealing compositions. The seal prevents high stresses between vessel and jacket by allowing the movement flexibility between two due to thermal expansion.

Glass jacket can be used for a maximum operating pressure of 0.5bar and a maximum operating temperature of 130 degree Celsius in jacket.  We manufacture jacketed vessels from 5Ltr to 200Ltr. capacity.

Beaded Glass

Borosilicate Glass Beaded Pipes are excellent corrosion resistant. The smooth surface of the glass prevents the sticking of the dirt & thus enables visual monitoring. Borosilicate Glass Beaded Pipes are best suited for chemically/organically contaminated waste water, waste gases, exhaust air, laboratory building drainage, Kitchen wastewater, sanitary wastewater, wastewater at airport runways etc. Borosilicate Glass Beaded Pipes are durable against acids, salty solutions & other organic substances. Due to the above, Borosilicate Beaded Pipe are better in such application in comparison to metals & plastics. All the beaded pipes are suitable for operating pressure of 0.5 bar (g). Beaded pipes joints are vacuum proof & are suitable for working temperature up to 120’C only.       We offer Beaded Pipes & components from DN 40 to DN 150. Incase you have requirement of bigger diameter component, feel free to discuss.
