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 stringent industrial pipeline connections, flange leakage, installation difficulties, and short service life are common challenges. The integral flanges provided by Carrian Forging use an integrated forging process that eliminates welding defects at the source, ensuring reliable sealing and easy installation, so your piping system can run continuously.

Integral flanges (also known as integrated forged flanges) are forged by Jianing using high-quality carbon steel, stainless steel, or alloy steel billets and processed as a whole by forging. The flange plate and neck are made of the same forged material, with no welds or joints, resulting in high structural strength and the ability to withstand extreme conditions such as high pressure, high temperature, and corrosive media. Our products are strictly manufactured according to GB, SH, HG, JB standards, and can also be customized according to customer drawings. They are widely used in petroleum, chemical, electric power, water conservancy, shipbuilding, and other fields.
One-piece forging, no welding defects:The flange and neck are forged from the same billet, eliminating welding stress and the risk of weld cracks, making the structure more reliable.
High pressure resistance, suitable for harsh working conditions:Forged dense structures enhance mechanical performance, meeting high pressure, high temperature, and alternating load conditions.
Tightly sealed to reduce leakage risk:Fine machining helps ensure the flatness and finish of the sealing surface, suitable for metal gaskets or wound gaskets.
Complete specifications, supports non-standard customization:Covers DN10-DN3000 and pressure grades PN6-PN400, with customizable dimensions, materials, and apertures according to drawings.
Integral flanges are customized products, and prices must be comprehensively calculated based on specific specifications (nominal diameter, pressure rating, material, sealing surface type, machining accuracy, etc.) and order quantity. We welcome technical drawings or technical requirements, and Jianing Forging will provide you with a targeted customized quotation plan.
All flanges come with material certificates and mechanical performance test reports;
Strictly control the production process according to the ISO 9001 quality management system;
Delivery time for standard specifications is 7-15 days; non-standard orders are confirmed through communication;
For quality issues, we offer returns and exchanges, and provide after-sales technical support.
