Stainless Steel Flange 304 Welded Flat Welding Flange Sheet Forging Gb Flange Plate Custom Non-Standard Flange PN10
Butt welding flange: Neck flange welding is often called "high
junction" flange. The purpose is to transfer pressure to the pipe,
thereby reducing the high stress concentration in the flange base.
Neck flange welding is the best design for butt welding those
supplied with flanges due to their inherent structural value.
However, the price is relatively high, because the production
process of the product is complex.
Threaded flange: The threaded flange is connected by a thread. But
the center of the product has a thread size corresponding to the
pipe. Its main advantage is that it can be assembled without
welding.
Sliding flanges: Sliding flanges have lower pivots as pipes enter
the single flange before welding. This is welded inside and outside
to provide sufficient strength and prevent leakage. Sliding flanges
are boring to match slightly larger od pipes. They are superior to
the welding of neck flanges, due to the lower initial cost for many
users, but the final installation cost probably will not be low,
because the increased welding of neck flanges is less.
Lap flange: The lap flange is actually exactly the same as the
sliding flange, except that it is a radius between the hole and the
flange race. It is necessary for the radius to have a flange to
accommodate the lap stub end. Usually, lap flanges and lap stubs
will be mated together at the end of the assembly system.
The socket weld flange is similar to a sliding flange unless it has
a hole and reverse hole dimensions. Counter holes are matched to
the pipe so that the pipe is inserted into the flange similar to
the sliding flange. The diameter of the smaller hole is the same as
the ID of the same pipe match. The limit is built into the hole,
which stays at the bottom as a shoulder sleeve designed for piping.
This eliminates any flow restrictions when using socket welded
flanges.
