Introduction to WN Flange

The full name of the neck flat welding flange is the neck flat welding steel pipe flange. It is a flange that extends the steel pipe and pipe fittings into the flange and connects with the equipment or pipeline through fillet welds.

function

Like the plate type flat welding flange, the neck flat welding flange is also a flange that extends the steel pipe and pipe fittings into the flange and connects with the equipment or pipeline through fillet weld.

Sealing form

The sealing surface forms of flat welding flange with neck are:

Raised surface (RF), concave surface (FM), convex surface (m), tenon surface (T), groove surface (g), full plane (FF).

A182 F51 is a duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance. The yield strength of duplex stainless steel is twice that of austenitic stainless steel. This feature enables designers to reduce the weight when designing products, making this alloy more cost-effective than 316317l. This alloy is particularly suitable for the temperature range of - 50 ° f / + 600 ° F. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially for welded structures.
