Isem tal-Prodott | Boltijiet tal-flanġ tal-istainless steel |
Materjal | Magħmul minn 18-8 / 304/316 l-istainless steel, dawn il-viti għandhom reżistenza kimika tajba u jistgħu jkunu manjetiċi ħafif. Huma magħrufa wkoll bħala l-istainless steel A2 / A4. |
Tip ta 'ras | HEX FLANGE HEAD |
Tul | Huwa mkejjel minn taħt ir-ras |
Tip ta 'ħajt | Ħajt oħxon, ħajt fin. Ħjut oħxon huma l-istandard tal-industrija; Agħżel dawn il-viti jekk ma tafx il-grawnd jew il-ħjut kull pulzier. Ħjut fini u żejda huma spazjati mill-qrib biex jevitaw li jinħallu mill-vibrazzjoni; Iktar ma tkun irqaq il-ħajt, aħjar tkun ir-reżistenza. |
Applikazzjoni | Il-flanġ iqassam pressjoni fejn il-kamin jilħaq il-wiċċ, u jelimina l-ħtieġa għal washer separat. L-għoli tar-ras jinkludi l-flanġ. |
Standard | Il-viti pulzieri jissodisfaw l-istandards tal-kwalità tal-materjal ASTM F593 u l-istandards dimensjonali IFI 111. Il-viti metriċi jissodisfaw l-istandards dimensjonali DIN 6921. |
