Flange is a kind of accessory commonly used for pipe connection. It usually consists of
two flat flanges and a weld connecting the two flanges. The main materials of this
product include carbon steel, stainless steel, alloy steel, etc., which can be selected
according to different working environments and requirements. Butt welding flanges are
widely used in pipeline systems in petroleum, chemical, natural gas, electric power and
other industries to connect pipelines, valves, pumps and other equipment to ensure the
safe and stable operation of the system. This product has the characteristics of easy
installation, reliable sealing, corrosion resistance, high pressure resistance, etc.,
and can meet the requirements of various complex working environments.
Commonly used models:
1. Standard butt welding flange: Butt welding flange manufactured in accordance with
international standards (such as ANSI, DIN, JIS, etc.) and commonly used to connect
pipes and equipment of corresponding standards.
2. Long welding neck butt welding flange: The welding neck length is longer and
suitable for high temperature and high pressure pipeline systems.
3. Short welding neck butt welding flange: The welding neck length is short and
suitable for general pressure piping systems.
