What is Screwed Flanges?

So, what exactly are Screwed Flanges? These are circular flanges with internal threads that match the external threads of a pipe. This allows pipes to be easily joined without welding, making them ideal for quick assembly and disassembly in applications where heat exposure must be avoided. As top-tier Screwed Flanges Suppliers, we manufacture these components using forged carbon steel, stainless steel, and alloy steel to ensure consistent strength and corrosion resistance in harsh environments. Each flange is engineered to meet rigorous pressure requirements while maintaining ease of maintenance.

Advantages of Screwed Flanges?

There are several advantages to using Screwed Flanges in both industrial and commercial piping networks. The primary benefit is the ability to connect pipelines without welding, which reduces the risk of heat-affected zones and speeds up installation. This is particularly valuable in systems handling flammable or hazardous materials. As reliable Screwed Flanges Stockists, we supply these flanges in large volumes to meet urgent project demands. Their reusability also means lower operational costs over time, and their design allows for easy access during inspection or repairs. Additionally, their compatibility with smaller pipe sizes enhances their versatility across industries.

Screwed Flanges Exporters like Metafit Piping Industries cater to a wide range of applications worldwide. These include oilfields in the Middle East, offshore platforms in the North Sea, and petrochemical facilities in the USA. Each flange is manufactured in compliance with international standards such as ANSI B16.5, ASTM A105, ASME B1.20.1, and EN 1092-1. Our products are available in grades including ASTM A182 F304, F316, and F321, ensuring chemical compatibility and pressure integrity under varying conditions. All flanges are fully traceable with mill test certificates and third-party inspection reports.

Screwed Flanges are known by various names around the world depending on local industry terminology. In the United States and Canada, they are referred to simply as “Threaded Flanges.” In the UK and much of Europe, the term “Screwed Pipe Flanges” is commonly used. Australian engineers might refer to them as “Threaded Face Flanges,” while in the Middle East and Asia, names like “Screw-Type Flanges” or “Thread Joint Flanges” are more common. Regardless of the naming, all refer to the same essential function — providing a secure, thread-based pipeline connection.
