Flanges
1.Welded neck flanges
-
Manufactured to connect the piping system by butt welding and is best for high pressure applications.
-
The neck or shaft transfers stresses from the shaft base to the wall thickness when butt welding, this provides an important edge reinforcement.
-
The bore of the flange matches the bore of the tube, this reduces flow turbulence and corrosion.
2. Slip on flanges
-
It is welded from inside and outside in order to provide sufficient strength to prevent leakage.
3 Blind flanges
-
Blind flange is basically a flange that does not have a hub or a bored center it is used to lock and seal the piping system or vessel openings.
4 Socket Weld Flange
-
It is a threaded flange which is similar to sliding flanges in shape, but has a cavity.
Valves
1- Gate valve
-
Gate valves are widely used in all application types
-
Suitable for above-ground and underground installation.
2- Ball valves
-
It was given this name because its body is spherical.
-
A ball valve is a flow control device which uses a hollow, perforated and pivoting ball to control liquid flowing through it.
-
It is open when the ball's hole is in line with the flow inlet and closed when it is pivoted 90-degrees by the valve handle, blocking the flow
3- Check valves
-
Check valves are one-way or nonreturn valves that open with fluid movement and pressure, and close to prevent backflow of the pressure.
-
It looks like a filter in Y shape.
-
It is used for steam and gases, as well as for liquids. It has less ability to hold impurities
