BU-Lok Valves & Fitting India Pvt Ltd is a specialized manufacturer known for its high-quality threaded flanges, designed to meet ASME/ANSI/DIN standards. We take pride in offering immediate delivery programs for both standard-sized carbon steel threaded flanges and stainless steel threaded flanges.
Threaded flanges serve a vital role in low-pressure piping systems, as they allow for easy and secure connections to pipes and equipment without the need for welding. While welding around the joint may be done after assembly, it is not considered the preferred method for expanding the flange's applications. Threaded flanges, also known as screwed flanges, resemble slip-on flanges, but their bores are threaded, facilitating assembly without welding. These fittings are typically used with pipes featuring external threads.
Our threaded pipe flanges are manufactured at our facility and cater to companies across various industries. These industries include shipbuilding, power generation, petrochemical plants, oil refineries, wastewater treatment plants, paper mills, pharmaceutical plants, and turnkey projects, among others.
We take pride in our global reach, with our products widely exported to countries and regions worldwide. Some of the regions we serve include the United States, Europe, Russia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka.
Threaded flanges are a type of flange used to connect pipes, valves, and equipment in a piping system. Unlike other flange types that use welding or bolting for connection, threaded flanges have internal threads that allow them to be screwed onto external threads of pipes or fittings. These flanges are typically used in low-pressure and low-temperature applications.
Threaded flanges have threads on the inner bore, which can be easily screwed onto the external threads of pipes or fittings. This makes them a convenient choice for assembling or disassembling components without welding.
Threaded flanges are primarily used in low-pressure piping systems. They are not suitable for high-pressure or high-temperature applications due to the limitations of threaded connections.
When properly installed, threaded flanges can create a reliable and leak-resistant connection. However, it's essential to apply sealing materials like Teflon tape or thread sealant to ensure a tight seal.
Threaded flanges can be used with pipes that have external threads, providing flexibility in piping configurations. They are often used in small-diameter pipes and applications where ease of assembly and disassembly is required.
Threaded flanges eliminate the need for welding, which can be advantageous in situations where welding is impractical or costly. This feature makes them suitable for temporary or frequently modified piping systems.
Threaded flanges are commonly found in industries such as plumbing, water supply, HVAC (heating, ventilation, and air conditioning), and smaller-scale industrial processes.
