Shanxi Jianing Forging produces a full range of flanges, including plate-type flat welding, neck butt welding, stainless steel, carbon steel, wind turbine tower tubes, pressure vessel flanges, blind plates, figure-8 blind plates, and threaded special-shaped flanges, all customizable with multiple sealing surface types, and a full set of production qualifications for stable supply.
In pipeline systems, the sealing and installation efficiency at flange connections directly affect overall operational stability. Common flange issues such as difficult installation alignment, seal failure, and short service life due to design or process issues are common. Our plate flat welded flanges use excellent carbon steel forging techniques. Fine machining helps stabilize the connection structure and facilitate easy installation, effectively reducing leakage risks and supporting efficient

Our plate flat welded flanges use excellent carbon steel forging techniques. Fine machining helps stabilize the connection structure and facilitate easy installation, effectively reducing leakage risks and supporting efficient project progress.
Plate flat welded flanges (carbon steel pipeline flanges) are standardized flange products suitable for low-pressure pipeline system connections. By welding the pipe ends through flat welding, it features a simple structure, controllable costs, and quick installation. It is widely used in pipeline engineering in industries such as petroleum, chemical, water treatment, and construction. We offer customized production, allowing adjustment of materials, dimensions, and pressure levels according to customer requirements to meet diverse application scenarios.
High-quality carbon steel forging: Carbon steel materials are selected and processed by forging, resulting in a dense structure and reliable strength, suitable for long-term use in common industrial environments.
Fine machining: The sealing surface is finely machined, resulting in high surface flatness. When combined with gaskets, it achieves a good sealing effect and reduces leakage risks.
Easy installation: The plate-type flat weld structure design requires minimal welding and easy alignment, effectively shortening installation time and improving construction efficiency.
Flexible customization: Supports production according to customer drawings or technical requirements, including different nominal diameters, pressure levels, and surface treatment methods, adapting to special working conditions.
