Flanges are an essential component of any piping system, as they provide a secure and leak-free connection between two pipes or valves. As the leading Flanges manufacturers, suppliers, and exporters in India, Bullion Pipes & Tubes LLP understands the importance of choosing the right type of flange for your application.
In this blog post, we will cover everything you need to know about flanges, including their types, materials, and applications.
Before we dive into the details, let's start with the basics!
Introduction
Flanges are mechanical connectors used to join two pipes or valves. They are usually made of steel, and their main purpose is to provide a tight and leak-free seal between the two parts. Flanges come in various types and sizes, and choosing the right type of flange is essential for the safety and efficiency of your piping system.
Types of Flanges?
Flanges come in several types, including weld neck, slip-on, socket weld, lap joint, threaded, and blind flanges. Each type has its unique characteristics and applications, and selecting the right one will depend on several factors, such as pressure ratings, temperature ratings, size, material compatibility, and cost.
● Weld Neck Flanges
Weld neck flanges are the most common type of flange, known for their high durability and strength. They are welded to the pipe or valve, making them ideal for high-pressure and high-temperature applications.
● Slip-On Flanges
Slip-on flanges are easy to install and remove, making them ideal for applications that require frequent maintenance. They slide over the pipe or valve and are then welded or bolted in place.
● Socket Weld Flanges
Socket weld flanges are similar to slip-on flanges, but they are welded only on the outer side of the flange, leaving the inner side free of welding marks. They are ideal for smaller-sized pipes and low-pressure applications.
● Lap Joint Flanges
Lap joint flanges are used when a piping system requires dismantling frequently. They are also ideal for applications that require easy access to the pipe or valve.
● Threaded Flanges
Threaded flanges are designed to be screwed onto the pipe or valve, making them ideal for applications that require easy installation and removal. They are commonly used in low-pressure applications.
● Blind Flanges
Blind flanges are used to seal the end of a pipe or valve. They are commonly used for pressure testing and maintenance purposes.
