Corrosion-resistant slip-on pipe flange
316L Yükseltilmiş Yüzlü Flanş Üzerinde Kayma
A forged stainless steel SORF flange designed to slide over the pipe for straightforward alignment and double-fillet welding in moderate-duty industrial piping.
What is a 316L slip on raised face flange?
A 316L slip on raised face flange is a forged stainless steel flange with a bore slightly larger than the pipe outside diameter. The pipe is inserted through the flange and secured with fillet welds at the hub and inside face. The raised sealing face concentrates gasket load in a defined contact area.
ASTM A182 F316L combines low-carbon weldability with molybdenum-enhanced corrosion resistance. A slip-on configuration can simplify fit-up and reduce installation cost compared with a weld neck flange, but the piping designer should confirm that it is suitable for the operating pressure, sıcaklık, cyclic loading and applicable code.

Sık sorulan sorular
What does SORF mean?
SORF means Slip On Raised Face. The flange slides over the pipe, is normally secured by fillet welds, and has a raised gasket seating surface.
What material is used for a 316L slip-on flange?
Forged stainless steel slip-on flanges are commonly ordered as ASTM A182 F316L, UNS S31603. EN 1.4404 is commonly specified for comparable European 316L applications.
Hangi ASME boyutları ve sınıfları mevcut??
ASME B16.5 covers pipe flanges through NPS 24. Slip-on raised face flanges are commonly supplied in Class 150 başından sonuna kadar 1500 where the flange type and size are defined by the standard.
How is a slip-on flange welded?
The pipe is inserted through the flange and positioned short of the gasket face. Inside and outside fillet welds are typically applied using an approved welding procedure and the project-specified fit-up detail.
When should a weld neck flange be selected instead?
A weld neck flange is often preferred for severe cyclic loading, high-integrity joints and more demanding pressure-temperature service because its tapered hub and butt weld provide a smoother stress transition. Final selection belongs to the piping designer.
Hangi sertifikalar sağlanabilir??
Tipik belgeler şunları içerir: EN 10204 3.1 malzeme sertifikası, ısı numarası izlenebilirliği ve boyutsal inceleme raporu. PMI and third-party inspection can be arranged when ordered.
