Repair kit part no. 7000013156 (replaces kit part no. 923321)

For use with color-port figure numbers 4591 thru 4595
glasses are accurately molded and tempered to yarway specifications. The assembly of glass, mica and gasket is registered precisely in the gasket groove in the body.
At boiler pressures above 300 psig, high temperature water will corrode unprotected gage glass. A thin sheet of high quality ruby mica on the inner surface of each port protects the gage glass from corrosive attack of steam, water and alkalis; however, this protection is not permanent. Continual exposure to high temperature, high pressure water will also corrode the mica shield. The rate at which this corrosion occurs is significantly less than that of glass, and is dependent upon a number of factors. Generally, the higher the operating temperature, the higher the rate of attack.
Warning: replace immediately when glass appears white or opaque. Failure to promptly replace the mica-gasket-glass assembly that appears white or opaque can result in catastrophic failure of the glass with violent discharge of hazardous high velocity steam. The discharge of high velocity steam can result in personal injury and property damage may occur.
Yarway recommends each customer establish a preventative maintenance schedule which insures the mica-gasket-glass assembly is replaced previous to the dissolution of the mica shield. In-service gages that have glass which appears white or is opaque, should be isolated immediately and the mica-gasket-glass assembly should be replaced before returning to service. Should any question develop on the condition of the gage glass, the procedure given under the section on preparation for washdown, auxiliary service or gage inspection of the installation, operation and maintenance manual of colour-port water level gages should be used to evaluate port glass condition.

Ramanlal chimanlal & co are toughened glass suppliers for industrial purposes toughned glass
we have a jumbo toughening furnace with a capability of 12000 * 3000 so can accommodateany glass faã�â§ade
canopy requirement.toughened glass is up to four to five times stronger than standard glass and does not
break into sharp shards when it fails. Toughened glass is manufactured through a process of extreme heating
and rapid cooling, making it harder than normal glass. The nature of toughened glass causes it to shatter
into small oval-shaped pebbles when broken. This eliminates the danger of sharp edges.
Due to this property, along with its strength, toughened glass is often referred to as safety glass.
There are two main types of heat treated glass, heat strengthened and fully tempered.
Heat strengthened glass is twice as strong as annealed glass while fully tempered glass is typically four to six times the strength of annealed glass.
Toughened glass must be cut to size or pressed to shape before toughening and cannot be re-worked once toughened. Polishing the edges or drilling holes in the glass is carried out before the toughening process starts.
Clear glass solutions have toughened glass is available as:
thickness of 4mm to 25 mm including 4mm,5 , 6 , 8, 10, 12, 15, 17, 19,22 mm
panels sizes up to 12000mm x 3000 mm
custom sizes to your specific project requirements
holes, cut outs, and raking to your requirements
flat double edge polishing, bevel edged

Maxosã�â® long form transparent
the mechanical strength and pressure resistance of the transparent glasses is attained through the thermal pre-stressing, homogeneity, flatness, precise dimensions and flawless surface of safety glass.
Technical characteristics of maxosã�â® long form
bending strength is determined by the surface compressive stress and the inherent resistance of the glass. The inherent resistance is heavily dependent upon the surface quality.
For safety reasons, the stress to the glasses caused by internal forces, thermal stress and vessel pressure have to be totally absorbed by the surface compressive stress so that a tensile stress of the glass surface is prevented.

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 ã��ã¯â¿â½ 10ã�â¢ã¯â¿â½ã¯â¿â½6 kã�â¢ã¯â¿â½ã¯â¿â½1 at 20 ã��ã�â°c), making them resistant to thermal shock, more so than any other common glass. Such glass is less subject to thermal stress and is commonly used under steam boilers in various industries .
Glasses containing 15ã�â¢ã¯â¿â½ã¯â¿â½25% b2o3, 65ã�â¢ã¯â¿â½ã¯â¿â½70% sio2, and smaller amounts of alkalis and al2o3 as additional components, have low softening points and low thermal expansion. Sealability to metals in the expansion range of tungsten and molybdenum and high electrical insulation are their most important features. The increased b2o3 content reduces the chemical resistance; in this respect, high-borate borosilicate glasses differ widely from non-alkaline-earth and alkaline-earth borosilicate glasses
