What is the plastic flange?

The plastic flange is a pipe component used to connect two lengths of the plastic pipe. The flange usually consists of a flat disk of larger diameter than the pipe, each disc having an equally located range of holes arranged around its surface by a short way from its outer edge. To connect to the pipeline, the flange is connected to one end of each pipe length. Both flanges are then placed against each other and attach the holes together that efficiently connect both pipes together. In high-pressure systems, other packages or o-rings are placed between the flanges to increase the integrity of the seals they form. They are inert and hygienic, lightweight and easy to connect using plastic flange systems. The flange joint is cost -effective, simple and easy to install and dismantle when it is needed. Basic Principle on which plastic flange joint a. In fact, most of the flanges are, based, it is screwing or screwing two flat discsjoined to the ends of the individual lengths of the pipeline.

There are two basic types of plastic flanges, namely free and captured discs, with the type of wheel is easier of two and most commonly used for plastic pipes with a small breakup. These flanges consist of a sleeve with a flat diameter disc at its one end. A number of evenly distributed holes are located around the disk surface for a short distance from the outer edge. Two sleeves are either screwed or epoxrated at the end of two sections of pipes with discs towards the outside. The discs are then placed against each other and screwed together through the holes that cover the pipes and create a tight joint.

This type of plastic flange is easy and quick to use, but requires that at least one section of the pipeline be freely rotated so that the holes in each flange discs can match each other. In cases where the pipelineIt is not often possible to turn, as is often the case with large high -pressure systems, a plastic free disk flange is preferable. These flanges consist of a simple flat plastic disk similar to those found on the captain's flange, but without integral sleeves. The disk slips around the pipe and at the end of the pipe is stopped by a small lip. The disk has a pop -up groove along its inner edge, into which the lips are suitable, preventing it from defending the joint.

6 These high-pressure flanges often have other grooves sliced ​​into the disk surfaces, into which a package or O-ringing screws is inserted before tightening. This is used to further improve the quality of the seals between two flange units.
