We can supply flanges in various grades of stainless steel or nickel-based alloys. Forgings, semi-finished products, or finished flanges are available, with extremely short delivery times.
The main characteristics of API standard flanges include:
Standardized Design: API standard flanges are designed and manufactured according to unified standards, ensuring consistency in size, shape, and performance, facilitating installation and maintenance.

High Strength: API standard flanges are typically made of high-strength materials such as carbon steel and stainless steel, enabling them to withstand high pressure, high temperature, and highly corrosive environments.
Excellent Sealing Performance: The sealing surfaces of API standard flanges are precisely designed to ensure excellent sealing performance of pipe connections, reducing the possibility of leakage.
Ease of Installation: The design of API standard flanges makes installation relatively simple, requiring no special tools or skills.
Interchangeability: Due to their standardized design, API standard flanges are interchangeable with many other standard piping components, increasing their compatibility and replaceability.

Corrosion Resistance: Depending on the materials and surface treatments, API standard flanges offer a certain degree of corrosion resistance.
Good Fluid Flow: The design of API standard flanges takes fluid flow into account, allowing for smoother fluid movement within the pipeline.
Wide range of applications: API standard flanges are widely used in pipeline connections in the oil, gas, chemical and other industrial sectors.
