Flanges used for steel pipeâ??s connection are various. So we should make our flanges lead to the purpose of our steel pipes like seamless or erw steel pipe. So we need to do some lesson before purchase. Function of long weld neck flanges is predominantly on vessels. We know that vessels have some places need an extended neck so flange can do this job for us. The purpose of tapered neck is to reduce the thickness of the steel and it then seems to be a pipe extension. The combination of steel pipe and long weld neck flange would make the whole engineering project easy and convenient. Utilized in the chemical and petroleum industries, as well as commercial and residential buildings that experience high levels of stress and temperatures that fluctuate, flanges have played an important part during our daily life.

These flanges are available in carbon steel, stainless steel 304/316, and alloy grades, conforming to ANSI/ASME B16.5 or API standards, and are widely sourced from China, India, and Turkey for global trade. Common sizes range from DN15 to DN600 (1/2" to 24"), offered with RF (Raised Face) or RTJ (Ring Type Joint) facing for diverse sealing requirements.
