Blind flange is put at the end of pipe or at the junction that would possibly be a future expansion into that direction.
Piping is easier to drill or weld at the construction stage. Once it was in use, drilling or welding will need prolong cleaning especially when the fluid transferred is combustible. For the mean of future extension, either the blind or valve would be used to seal the end.
Yes, there are different types of PVC flanges, primarily categorized by their design and application. Common types include slip-on flanges, threaded flanges, and blind flanges, each serving specific purposes in piping systems. Additionally, they can vary in pressure ratings and sizes to accommodate different plumbing and industrial requirements. The choice of flange type depends on the installation needs and the compatibility with other piping components.

"A spectacle blind - also known as a figure-8 blind - is generally a piece of metal that is cut to fit between two pipe flanges and usually sandwiched between two gaskets. A spectacle blind is often made from two metal discs that are attached to each other by a small section of steel. The shape is similar to a pair of glasses or "spectacles" - hence the name spectacle blind. One end of the blind will have an opening to allow flow through the pipe during operation and the other end is solid to block flow during maintenance. They are generally installed as a permanent device to separate process piping systems."[1]The whole idea of a spectacle blind is so that one can be absolutely sure that an item of equipment is properly and securely blanked off with no possibility of any flow or leakage through a valve during maintenance. The flow can be diverted to other items of equipment but not just bypassed around the blank as this would compromise the safety function of the spectacle blind. The flow has to valved off and pressure relieved prior to loosening flange bolts and swinging the blind.References1.

6A-6B flanges are ring type joint which is not developed for face to face make up, where the bolting forces act on gasket. 6A-6BX flanges are also ring type joint but it is developed with raised face hence the bolting forces act on this raised face and not on the gasket if it is properly placed. And also the raised prevent the flange damage from excessive bolting torque.
API standard flanges are specialized flanges designed according to the American Petroleum Institute (API) specifications, primarily used in the oil and gas industry. These flanges ensure compatibility and safety in high-pressure and high-temperature applications, facilitating the connection of piping systems and equipment. They are characterized by specific dimensions, pressure ratings, and material requirements to meet industry standards and regulations. Common types include API 6A flanges for wellheads and API 16A flanges for subsea applications.

Different types of flanges are used in piping systems based on pressure, temperature, and application needs. Common types include weld neck flanges (ideal for high-pressure systems), slip-on flanges (easy to install), blind flanges (used to close pipe ends), socket weld flanges (for small, high-pressure pipes), and threaded flanges (no welding required). Choosing the right flanges for industrial piping applications and pressure systems ensures leak-proof connections and long-term durability. Each type serves a specific purpose depending on the project requirements. For reliable quality and performance, brands like Navrang Steel offer a wide range of flanges designed to meet industrial standards and demanding environments.

Stainless steel flanges come in various types, each designed for specific piping and pressure applications. The most common types include weld neck flanges, which are ideal for high-pressure systems due to their strong connection; slip-on flanges, which are easy to install and commonly used in low-pressure applications; and blind flanges, used to seal the end of a pipe or valve. Other types include socket weld flanges, suitable for small-diameter high-pressure pipes; threaded flanges, which can be fitted without welding; and lap joint flanges, often used with stub ends for systems that require frequent dismantling. These flanges are widely used across industries such as oil and gas, chemical processing, and construction, with materials supplied by companies like Astec Tubes for various industrial applications.
