slip on flange flat face

1) Slip-On Flanges The slip-on flange has a low hub because the pipe slips into the flange prior towelding. It is welded both inside and out to provide sufficient strength and preventleakage. Slip-on flanges are all bored slightly larger that the O.D. of thematching pipe. They are preferred over welding neck flanges by many users due totheir lower initial cost, but final installation cost is probably not much lessthan that of the welding neck flange because of the additional welding involved.   2)Specification    Type: slip on flange   Specification: NPS1/2"-NPS24"  Size: 15 mm to 5000 mm  Norminal  pressure: Class150,Class300,Class400,Class600,Class900,Class1500  Connection:welding  Sealing surface:RF(0.25-2.5.PN)  Material: stainless steel ( ASTM A403 F304,F304L,F316,F316L )  Standard: ASME B16.5,EN1092-1 ect.   Marking:  Packing: wooden case,wooden pallet or as customers'require Delivery time: from 7 days to 25 days Supply ability: 1000000 pieces/month Payment terms: T/T .L/C   3)Product               4)Certificate We have passed ISO , API and CE .
