Ductile iron pipe fittings with flanges

Posted by zora li on June 25th, 2024

Ductile iron pipe fittings with flanges mainly include:

1. Ductile iron flange: This is a ductile iron pipe fitting with flanges, usually used to connect two or more pipes.

2. Ductile iron flange blind plate: This is a ductile iron flange pipe fitting used to close the end of the pipeline, usually used to temporarily close the pipeline during pipeline maintenance or expansion.

3. Ductile iron flange stop valve: This is a stop valve with flanges, usually used to regulate or cut off the fluid in the pipeline.

The ductile iron flange stop valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to not leak. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem should be larger, otherwise the valve stem top bending failure will occur.

4. Ductile iron flange silencer check valve: This is a silencer check valve with flange, which is usually used to reduce the noise generated when the fluid flows back.

5. Ductile iron flange pipe clamp: This is a pipe clamp with flange, which is usually used to fix pipes or support other pipe fittings.

In addition, there are other ductile iron pipe fittings with flanges, such as ductile iron reducers, ductile iron grates, ductile iron water supply pipes, ductile iron pipe clamps, ductile iron standards, half-section ductile iron, ductile iron elbows, ductile iron flexible joints, ductile iron steel-plastic pipes, ductile iron valve boxes, etc. These pipe fittings are designed and manufactured with the needs of flange connection in mind, and can meet a variety of different pipeline connection needs.
