Compared to the design developed according to DIN 28120, the 318 sight glass is significantly thinner and lighter. The type 318 sight glass is a cost-effective alternative for low-pressure operations, fitting perfectly into our range between the 317<\/strong><\/a> model for pressureless operations and the more robust 320<\/strong><\/a> version. <\/p>\n

Despite the lower requirements, our type 318 product sight glasses are made of the same high-quality stainless steel<\/strong> 1.4571 (316Ti) highly valued by our customers. The glass material used is industry-proven 3.3 borosilicate glass according to DIN 7080 (or similar). <\/p>\n

The connection is sealed with flat gaskets adapted to your needs<\/strong> from an extensive range of materials, which, in addition to the widely used fiber gaskets, also include more sophisticated materials such as PTFE (Teflon\u00ae), NBR, graphite, and many other brand-name gaskets.<\/p>\n

If the maximum operating temperature of 280\u00b0C does not meet your requirements, or if the process conditions pose a problem even for the highly resistant borosilicate glass, a mica or FEP protective screen specially adapted for the connection offers additional protection against steam and aggressive chemicals, such as alkalis up to a pH value of 14.<\/p>\n

Like other circular product sight glasses, the 318 sight glass can be equipped with an SGW-type wiper, spray devices, or lights upon request.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n
