GL™ has exellent corrosion resistance to any acid substances except for hydrofluoric acid.
The below charts show GL™ corrosion-proof performance with major acid substances and water.
※ Generally, glass has resistance to acid substances. However, it may be corroded by boiled water, steam,alkaline, and alkaline substances depending on the operating conditions.
Please contact with us if using the above materials for testing, trial operation and cleaning.
※ Regarding the ceramic lined parts of spacers (SP) and blind flanges (CF), usage temperature limit of corrosion resistance is 150℃ or less.
- ●Operating temperature
- Standard GL™: -15~150℃ (depending on fluid type)
There are practical examples -45~+250℃
(depending on materials and gaskets) - ●Thermal shock
- Thermal shock: Up to 70℃.
*Please avoid from rapid heating or cooling.
- ●Pressure capacity
- Maximum allowable operating pressure of GL™ is up to 0.98Mpa(10kgf/cm2).
Please contact with us when using in excess of the above pressure. - ●Bending stress
- GL™ 3/4B Pipe is durable up to 4.9kN by Amsler testing machine(400mm).
- ●Impact
- GL™ of Straight pipe is not broken when steel ball(95g) is dropped from the height of 600mm, and Fitting of cast iron type thicker than straight pipe is not broken when the steel ball(175g) is dropped from the height of 600mm.
*However, care should be taken to avoid impact when handling.
- ●Flange types
- ANSI 150Lb type
JIS 10K type
- ●Base material
- Straight pipe SGP ＋ SS400 (JIS)
Fittings(standard) SGP ＋ SS400 (JIS)
- ●Between joint faces
- ANSI 150Lb type
- ●GL™ (GL™, GLP™) is lined inside surface of steel pipes, so it can be difficult to recognize differences with ordinary steel pipes from the appearance. Therefore, unexpected glass breakage may occur. Basically, please pay attention to handle the pipes correctly. Please avoid from external impact, bending, tension, compression and fire.
- ●Product specifications are subject to change without any notice.
- ●Some products in the catalog are subject to the Export Trade Control Order, so please contact with us when you have a plan to export GL.
