 Borosilicate Gauge Glass   Product Description    Transparent glasses are also manufactured from “extra-hard” borosilicate glass. The surfaces on both sides are finely smooth and  ensure optimal transparency. Now we have two kinds manufacturing technique: One is as same with reflex Gauge Glasses, use moulds to make the semi-finished products, afterwards, ground and polish the two side to ensure optimal transparency. By this manufacturing technique, the definition isn’t good. The other manufacturing technique is: At first, we manufacture 17mm thickness glass sheet, then cut the glass sheet according the detailed size and polish the side face for the smooth. This manufacturing technique glass is very clear, but the goods cost is higher. It can be used with all media at service conditions up to 6MPa and temperatures up to 260 °C.

Level Gauge Glass Physical Property
Testing Item	Standard Rules
1. Appearance	1) Air bubble: Diameter≤0.5mm,in the 10mm x 10mm area the quantity must be ≤3. Diameter from 0.5mm to 1.5mm dispersive air bubble,there is less 2 on the sight plane and less 5 on the No-sight plane. Their distance must be >40mm. The air bubble of Diameter from 1.5mm to 2mm ≤3  on the No-sight plane. Their distance must >40mm. On the sight plane, The distance to the side in 7.5mm,the air bubble of the  diameter2) The glass don’t allow slag and scrap iron,etc. impurity. 3) Stripe : don’t allow have palpable filaceous and pectinate stripe on the sight plane. 4) Cockle: In the side face,don’t allow have the cockle of depth >1mm. 5) Crack: don’t allow have crack. 6) Scrape: On the sight plane and in the 7.5mm to edge,the scrape of less than 10mm don’t allow more 2 strips. 7) The sight plane must be polishing,and sealing side must be rubbing and polishing.
2. Colour and Lustre	It should be no color and transparent,and with its self tine green is allowed.
3. Water-resistance	Cooked in the water for 5 hours,then weigh up ,then titration with 25ml    0~31    ug/g
4. Alkali-resistance	Cooked in the 0.5N NaoH for 3 hours,then Weigh up,weightlessness should be ≤75  mg/dm2
5. Temperature-resistance impacts capability	Put it into electric cooker,keep for 7min under the temperature of 260°C±1°C,then,put into the water of 20±1°C,it should not crack
6. Bend-resistance	≥80 MPa

     Installation instructions Applications/ Use and Care                              Please read the following information — it concerns your safety. Each of our sight and gauge glass carefully manufactured and tested. It can only fill its duties safely and to your complete satisfaction if both the working conditions and information about its assembly and use are taken into account. We are pleased to provide you with some information on this page. Fittings: You should always observe the manufacturer's instructions for assembling and changing sight and gauge glasses. The basic fittings and flanges must satisfy the normal requirements for working under temperature and pressure conditions. It is particularly important that the flatness and freedom from distortion of the sealing surfaces can be guaranteed. These must satisfy at least the same requirements as are guaranteed for the sight and gauge glasses. The flatness should be checked when the sealing surfaces have been thoroughly and completely cleaned. Never reuse a sight or gauge glass that has already been exposed to process conditions. Sealing material: Always use new gaskets for assembly and use the sea-manufacturer of the fittings. These gaskets must also be flat and undamaged. Mica protection  shields can be used to increase the working life of sight and gauge glasses and to allow them to be exposed to higher temperatures. However reflex glasses cannot be protected in this way. During assembly the glass must always be centred in the fitting in order to avoid a glass-metal contact. The correct sequence must always be observed when assembling the glass, gasket and mica protection shield. Sequence for Tightening Cover Bolts/ Nuts
Tightening the Fitting screws:
First tighten
The clean and greased nuts by hand.Then tighten them In the sequence shown in the D i a g r a m Always start in the middle and then work outwards on alternate sides. Finally, tighten the flange bolts or nuts to the exact torque given by the manufacturer. During operating processes  never try to clean the glass by mechanical means,never tighten up the nuts and bolts of the fitting and never perform other work on the fitting. Transport packing is used to protect the glasses. Please leave the glass in packing until they are required for use and avoid contact with other glass or metal components. Sight and gauge glasses which are scratched, chipped, pitted or any other surface damage exist, should never be used. Sight and gauge glass condition Checks should be carried out regularly; when used in new and unknown processes daily. Keep maintenance records and replace the glasses on a regular basis. Look for damage,scratches and loss of substance. Cleaning the glasses: please only use commercially available glass cleaning agents to clean the glasses. Never use wire brushes, metal scrapers, or other sharp-edged items Which could scratch the glass and make it unusable. Opaque and rough glasses which cannot be cleaned with simple cleaning agents should be replaced. Our aim is to inform and advise our customers. Nevertheless,general values obtained from experience and test results simply cannot be applied to particular and specific applications. Too many factors which we cannot influence play a role. We must therefore ask you to appreciate that no claims can be made which may arise as a result of any advice we may have provided. You are responsive to property care for and maintain the sight glasses. Packaging & Shipping       Company Information
