Socket Weld Flanges are used in high-pressure, small-diameter piping systems where a secure, leak-free joint is essential. These flanges are welded to the pipe end, ensuring excellent alignment and structural integrity for industrial fluid control applications. As a global manufacturer and supplier, Lianhe Valve (Wenzhou Lianhe Valve Fitting Co., Ltd.) produces stainless steel flanges that meet international standards, serving industries such as oil and gas, chemical processing, and water treatment with reliable performance and long service life.
Our Socket Weld Flanges are engineered for durability and precision. They are ideal for high-pressure applications where leak prevention and mechanical strength are critical. Each flange is machined for smooth bore alignment, ensuring a secure weld and efficient flow. Key benefits include:
Excellent corrosion and high-temperature resistance
Precision machining for dimensional accuracy
Long service life with minimal maintenance
Certified to ISO, CE, and ECA standards
All products comply with ASME, DIN, and ANSI standards, ensuring compatibility with global piping systems. Technical data and product details are available in our Socket Weld Flanges technical downloads.
Our ASME B16.5 Socket Weld Flanges are available in various pressure ratings and dimensions to meet diverse installation needs. They conform to international dimensional and material standards:
| Standard | Designation | Typical Pressure Class |
