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 high-pressure, corrosive media conveying scenarios, ordinary flanges often cause leaks and breakage due to insufficient welding strength or poor corrosion resistance of materials, resulting in high maintenance costs and even affecting the safe use of the entire pipeline. The stainless steel butt weld flange uses 304 material and butt welding technology, with the end groove seamlessly integrated with the pipeline, effectively eliminating stress concentration points, providing reliable sealing
In high-pressure, corrosive media conveying scenarios, ordinary flanges often cause leaks and breakage due to insufficient welding strength or poor corrosion resistance of materials, resulting in high maintenance costs and even affecting the safe use of the entire pipeline. The stainless steel butt weld flange uses 304 material and butt welding technology, with the end groove seamlessly integrated with the pipeline, effectively eliminating stress concentration points, providing reliable sealing and pressure resistance, and reducing leakage risk.
Stainless steel butt welded flanges (304 high-voltage welded flanges) are pipeline connectors specially designed for high-temperature, high-pressure, and corrosive environments. Made from high-quality 304 stainless steel forged and formed, the end bevel design facilitates butt welding to pipes, helping to ensure uniform and stable weld quality. Pipeline systems suitable for industries such as chemical, petroleum, electric power, and pharmaceuticals, meeting the demands of various demanding working conditions.
Reliable materials: Made with 304 stainless steel, corrosion-resistant and high-temperature resistant, suitable for various media environments.
Butt welding structure: end groove design, forming an integral piece after welding with the pipeline, offering high strength and good sealing.
Fine forging: Processed using forging technology, resulting in a dense internal structure and stable mechanical properties.
Complete specifications: Multiple nominal pressures, bore diameters, and sealing surface types are available to meet different connection needs.
This product is a non-standard custom flange, and is calculated separately according to the specific specifications provided by the customer (including pressure rating, bore diameter, material, sealing surface type, and quantity). Please provide detailed parameters or drawings, and we will offer you a targeted quotation after evaluation.
All products undergo appearance, dimension, and pressure testing before leaving the factory, helping to meet relevant standards.
We provide full-process technical support, from model selection consultation to after-sales installation guidance.
Strictly adhering to the delivery schedule stipulated in the contract helps ensure that project progress is not affected.
For product quality issues, we provide timely responses and solutions.
