Product Description

Material technical requirements

1.Flange material
ASTM A105: Carbon steel (general industrial pipeline), -29~425℃
ASTM A182 F316: Stainless steel (corrosive medium), -196~800℃
ASTM A350 LF2: Low temperature carbon steel (LNG, etc.), -46~350℃

2.Window material
Borosilicate glass: Heat shock resistant (ΔT≤150℃), light transmittance ≥ 92%, ASTM E438 Type
Quartz glass: Temperature resistance up to 1000℃, but high brittleness, MIL-G-174B
Mica composite layer: Pressure resistance ≤ PN100, corrosion resistant, ASTM D351

Safety protection

1.Explosion-proof design: Burst pressure ≥ 2.5 times the working pressure (ASME Sec.VIII Div.1), laminated glass + wire mesh (to prevent debris from splashing)
2.Anti-fog technology: Electrically heated window (power 10W/cm²), nitrogen purging interface (to prevent condensation)
