- > RESISTANCE TO CHEMICAL
Borosilicate glass is inert to almost all materials except hydroflouric acid (HF) phosphoric acid((H3Po4) and hot strong caustic solutions. Of these Hydroflouric acid has the most serious effect, even when it is present in PPM (parts per million) in solutions. Where as phosphoric acid and caustic solutions cause no problems when cold but at elevatrd temprature corrosion occurs. in case of caustic solutions upto 30% concentration can be handled safely at ambient temperature.
Under actual operating conditions, the effect of turbulence, and traces of other chemicals in the solution may increase of 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�°C is 3.3 x 10-6/�°C. 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 25C and 300C is average to be 0.233Kcal/Kg, C
Thermal Conductivity
Thermal conductivity is 1.0 Kcal/hr,mC. Over the permissible operating temperature range.
- > RESHAPEING

Borosilicate tubular gage glass is designed with a red line between two white lines. The color contrast makes it easier to read the liquid level. This is achieved by the application of specially developed paints that are bonded to the glass without etching.
Material: Standard borosilicate glass 3.3
Diameters range from 1/2" OD to 1" OD
General Application: Tanks, reservoirs, low pressure boilers.
Ends Finish:may be cut, ground, or fire polished depending on application.
Pressure ratings range:from 90 PSI to 600 PSI depending on end finish, diameter, and length required.

Cast Iron and Ductile Iron tube and fittings PL739
Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.
The difference between ductile iron and gray iron
1. Different chemical composition
Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.
2. Different organizational structures
The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.
3. Different performance
Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.
Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.
