The union is made of malleable cast iron, also known as oil, a kind of pipe fittings, shape for three-dimensional polygon design, the inner layer is engraved with three-dimensional threads, the connection form is a fixed joint and a live female joint supporting use, both ends and the corresponding pipe threads are connected, the middle with PVC pad or rubber pad seal.
The main design advantage of the malleable steel siren is that the pipe joint can be removed by rotating the nut of the middle part of the siren, without rotating the pipe itself.
The specification of malleable steel pipe fittings is relatively small, and the commonly used specification range is 1/2-4 inches. According to its surface treatment, it can be divided into galvanized and non-galvanized two kinds.
This kind of malleable steel pipe fitting is mainly used for the connection of matching hardware fittings and can be installed in various pipe joints.
Because the joinings have the advantages of convenient installation and disassembly, malleable steel pipe fittings are used in the water systems, HVAC systems, fire protection systems, and other pipeline systems to change the direction, pipe diameter, and lead on the pipe fittings and so on.
As the shape of the pipeline is different, simple and complex, therefore, there are more types of pipe fittings.
Commonly used pipe fittings, such as oil elbow, tee, reducing pipe, pipe joint, official cap, etc.
The bending Angle of the commonly used elbow is 90°, 45°, and 180°. The 180° elbow is also called the U-bend. There are also special Angle elbows, but few of them.
