Product DescriptionPRODUCT DETAILSThe LUMISTAR Type 391 circular sight glass fitting is designed for direct welding onto pipelines or compact pressure vessels. Featuring an integrated pipe adapter, it offers a practical solution for real-time observation or illumination of internal processes in pressurized systems.Just like our other high-quality sight glasses, the Type 391 utilizes a pane of chemically durable borosilicate glass (DIN 7080 or equivalent), held securely between two precision stainless steel flanges. The structure is manufactured from 316Ti stainless steel (1.4571), known for its exceptional strength and corrosion resistance under demanding operating conditions.Technical detailsFlange material:Shape:Temperature:Baseflange:1.4571(factorystandard)Coverflange:1.4571(factorystandard)Othermaterialsonrequest1withpipeadapterforweldingontomedium-carryingpipesupto280°Cwithborosilicateglassaccording or similar toDIN 7080Sight glass:Nominal size:Options:Borosilicateglassaccordingorsimilar toDIN 7080DN 100 up to DN 350(dependingonnominalpressure)Wiper SGWwith PTFE or silicone wiperbladeLEDlightsforEX-andNon-EX-areasForvacuumapplications2(Type 390V)withthreadconnection(Type 392)Stainless-steelperforatedplate-impactprotectionFEPprotectivescreen(forhigherpH-values)Micaprotection(upto320℃withborosilicate glass DIN 7080)specialdesginsarepossibledependingonenvironmental variablesGaskets:Nominal pressure:Fiber;(KLINGERSIL?C-4400)PN16|PN 25|PN 40PTFE,FKM,NBR,Silicone,EPDMGraphite;oraccordingtocustomerrequirementsScrews:A2-70A4-70Optionalmaterials:1.0460/1.4301/1.4307(F304L)/1.4404(F316L)/1.4410(SuperDuplex)/1.4435(F316L)/1.4462(F51)/1.4529(ALloy926)/1.4539(ALloy904L)/1.4541(F321)/1.4547(F44)/1.4550(F347)/1.4571(316Ti)/1.4828/1.4841/1.4876(ALloy800H)/1.4878/1.7335/2.4068(Alloy201)/2.4360(ALloy400)/2.4375(AlloyK500)/2.4602(ALloyC-22)/2.4605(Alloy59)/2.4610(ALloyC-4)/2.4816(ALloy600)/2.4819(AlloyC-276)/2.4856(ALloy625)/2.4858(ALloy825)/3.7035(Titan)Screws:limited by gasketA4-70depending on environmental variablesOptionalmaterials:1.0460/1.4301/1.4307(F304L)/1.4404(F316L)/1.4410(super Duplex)/1.4435(F316L)/1.4462(F51)/1.4529(Alloy 926)/1.4539(Alloy 904L)/1.4541(F321)/1.4547(F44)/1.4550(F347)/1.4571(316Ti)/1.4828/1.4841/1.4876(Alloy 800H)/1.4878/1.7335/2.4068(Alloy 201)/2.4360(Alloy 400)/2.4375(ALloy K500)/2.4602(Alloy C-22)/2.4605(Alloy 59)/2.4610(Alloy C-4)/2.4816(Alloy 600)/2.4819(Alloy C-276)/2.4856(Alloy 625)/2.4858(Alloy 825)/3.7035(Titan)PNDNDa[mm]Di [mm]A[mm]s[mm]Weight [kg]*1610022010711433,610,51252501321397414,515028516016834,518,6200(PS max.10 bar(g))34020721916,328,2300(PS max.6 bar(g))46031023297,155,7350(PS max.6 bar(g))520340355687825/4010023510711433,614,8(PN 40)1252701321397421,1(PN40)15030016016834,527,5(PN 40)20037520721916,352,6(PN 40)*Weight depending on size of DLumistar Special Glass Technology Co., Ltd. is a professional enterprise that produces safety glass windows and water level gauge glass windows.
