'<br>Flange fitting is essential for gas pipelines carrying chemical materials. A pipeline having a large diameter pipe requires flange fitting in order to avoid excessive wear and tear. This also ensures that the inner diameter of the pipe remains the same during the span of the pipeline. The inner diameter of a pipeline can either be small or large, depending on the application. For instance, a small diameter pipeline fitted with a large external diameter bolt will require a different configuration than a larger one, where the inner diameter is smaller.<br><br><br>How to Find a Flange Fitting Type. Knowing the type of flange will help you narrow down your selection and makes it easier to locate the right fitting for the job. Type of Flange. The type of flange can be single-point, high pressure, or double-point. High pressure is used in situations when high pressure is needed, such as in an explosion-proof chemical vented system.<br><br><br>Types of Flange Fittings. The types of flange fittings vary depending on the application. Commonly used types of flange fittings are high pressure, single-point, and double-point. High-pressure flanges are commonly used for pressure-temperature ratings up to 300 psi; single-point flanges are used for low-pressure applications up to five psig; and double-point flanges are employed for all three purposes, depending on the application. The common types of flange fittings are discussed below.<br><br><br>Single-Point Flange Fitting. Single-point flange fittings are the cheapest among all types of flange fitting. It uses a single gas passage through the pipe joints. They are mostly used in small joints where one-way flow is required.<br><br><br>Double-Point Flange Fittings. Double-point flange fittings use two gas passages. If you have any concerns relating to wherever and how to use [https://www.shunchengvalve.com/best-quality-swing-check-valve/ Read the Full Report], you can call us at our own web-site. One-way flange fittings can only be shut with the help of a solenoid switch. They are generally used in high pressure areas. Dual-point flange fittings, on the other hand, use both gas directions for controlling the flow rate.<br><br><br>Installing Flange Products. Before installing any flange fitting, make sure that you have enough time for installation and you are working with a trustworthy and licensed plumber. Also, make sure that you have all the necessary tools and equipment to install the flange. Most often, it is seen that people cut corners when it comes to flange fitting and do not pay much attention to the quality of materials used. Thus, it is advised to opt for high quality products. Quality is the most important aspect for flange joints as the pipe will be exposed to varying temperatures and pressures during its lifetime.<br>'
