Threaded Flanges are vital components in industrial piping systems, providing secure, leak-free connections without welding. Their internal threading enables quick installation and removal, making them ideal for maintenance or low-pressure operations. As a professional stainless steel flange manufacturer and supplier, Lianhe Valve (Wenzhou Lianhe Valve Fitting Co., Ltd.) delivers high-quality stainless steel threaded flanges that comply with international standards and ensure dependable performance across diverse industries.
We offer a complete range of Threaded Flanges to meet various piping requirements. The main types include:
Standard Threaded Flanges – for general-purpose piping systems.
Reducing Threaded Flanges – designed to connect pipes of different diameters.
Blind Threaded Flanges – used to close pipe ends securely.
Each type is available in multiple materials, thread configurations, and pressure ratings to ensure compatibility with different pipe fittings and valves. For more details, visit our Threaded Flanges FAQs.
Our stainless steel threaded flanges are available in SS304 and SS316 grades, along with carbon steel and alloy steel options. Every flange is produced under strict compliance with ASME B16.5, ANSI, DIN, EN, and ISO standards. This ensures durability, corrosion resistance, and reliable performance in demanding environments.
| Material | Standard | Key Features |
|---|---|---|
| Stainless Steel (SS304, SS316) | ASME B16.5 / DIN / ISO | Corrosion resistance, long service life |
| Carbon Steel | ANSI / EN | High strength, cost-effective |
| Alloy Steel | ASME / ISO | Enhanced durability under pressure |
Threaded Flanges are widely used across industries for their easy assembly and disassembly. They are particularly suitable for systems where welding is not feasible, such as low-pressure or maintenance-intensive operations. Common applications include:
Oil and gas pipelines
Chemical processing plants
Water treatment systems
Construction and HVAC installations
Their compatibility with various fittings and valves ensures seamless integration into industrial piping systems.
Selecting the correct Threaded Flange involves evaluating several key factors:
Flange dimensions – ensure compatibility with connected pipes.
Thread type – match with pipe threading standards (NPT, BSP, etc.).
Pressure rating – confirm it meets system requirements.
Material selection – choose based on temperature, corrosion, and environment.
