Socket Weld Flange, Asme ANSI B16.5, Asme ANSI B16.47 Flanges
The socket welding flange is called (SW flange), and the basic
shape of the socket flange is the same as the flat welding flange
with neck. A socket is opened in the inner hole of the flange, and
a pipe is inserted into the socket and welded. Weld the weld ring
on the back of the flange. The crevice between the socket flange
and the grass groove is prone to corrosion, and corrosion can be
avoided if the inner weld is welded. The fatigue strength of the
inner and outer welded socket flanges is 5% higher than that of the
flat welded flanges, and the static strength is the same. When
using this Socket Flange, its ID must match the ID of the pipe.
Socket flanges are only suitable for pipes with a nominal diameter
of 50 or less.
Plug welding flange sealing surface shape: convex surface (RF),
concave and convex surface (MFM), tongue surface (TG), annular
joint surface (RJ)
Socket welding flange applications: boiler pressure vessels,
petroleum, chemical, shipbuilding, pharmaceutical, metallurgy,
machinery and elbow stamping industries.
Socket welding flanges are usually used in pipes with PN≤10.0 MPa
and DN≤50.
Product Information:
To protect the flange, for small size, we will pack them into
plywood case. For large size, we will also pack them into plywood
case and protect them very well. But if we deliver it in a
container, we will load them ino pallet. It is also a protective
method.
Concentrate on customers' demand and support you with our sincere
is our soul.
