Flange is a discoid parts, in the pipeline project, the most common use of the flange are paired. In the pipeline project, mainly used for pipeline flange connection. The need to connect the pipeline, installed a variety of flange, low-pressure pipelines can use silk to flange, four kilograms more than the pressure of the use of welding flange. Between the two flange with sealed, then bolts fastening. The pressure flange have different thickness and use a different bolt. Pumps and valves, and pipes connect, these local equipment, but also made corresponding to the flange shape, also known as the flange connection. All in two plane surrounding the use of bolts in the connector link at the same time closed the parts are generally referred to as "flange", such as ventilation pipe connections, the parts can be called "flange parts." But this connection is only a partial equipment such as pumps and the flange connection, not the pump is "flange parts." Such as the relatively small valves, etc., can be called "flange parts."
Flange connecting the construction of the pipeline is an important connection.

Flange is connected to two pipes, fittings or equipment, to their respective fixed in a flange on the flange between the two, together with flange pad, together with bolts fastening to complete the connection. Some of the pieces of equipment have been built and the flange, is a flange connection.

The flange connecting thread (silk T) flange and welding flange. Low-voltage wire to a small-diameter flange, high pressure and low pressure are the use of large diameter welded flange, different pressure the thickness of the flange and bolt diameter and the number is different.

According to the pressure on different levels, the flange pad have different materials, asbestos from the low-pressure pads, high-pressure pad to asbestos have metal pad.

Flange connection easy to use, able to withstand greater pressure.

In the industrial pipeline, the flange connected to the use of a very wide range. Within the family, small diameter pipeline, but is low pressure, invisible flange connection. If the boiler room or a production site, are everywhere flange connection of pipelines and equipment.
