Stainless Steel Threaded Flanges

Stainless Steel Threaded Flanges

Stainless steel threaded flanges are specialized components used in piping systems. They rely on internal threads to be screwed directly onto corresponding threaded pipes or fittings without the need for welding, providing a safe and leak-proof connection with corrosion resistance and durability. It provides convenience in installation, disassembly and maintenance and is commonly used in industries such as chemical, oil and gas, pharmaceutical, food and beverage, and water treatment.

What‘s The Feature Of Stainless Steel Threaded Flange?

Stainless Steel Threaded Flanges are made from high-quality stainless steel, which offers excellent corrosion resistance, durability, and strength. Stainless steel is widely known for its ability to withstand harsh environments, making it suitable for various industrial applications.

These flanges have internal threads that allow them to be directly screwed onto the corresponding threaded pipe or fitting. The threaded connection provides ease of installation, disassembly, and maintenance, eliminating the need for welding or other specialized tools.

Stainless Steel Threaded Flanges provide a secure and leak-proof connection between pipes or fittings. The threaded design ensures a tight seal, minimizing the risk of leakage and ensuring the integrity of the piping system.

These flanges are versatile and can be used in a wide range of industries and applications. They are commonly used in chemical processing, oil and gas, food and beverage, pharmaceuticals, water treatment, and other industrial sectors.

Stainless Steel Threaded Flanges are designed to withstand high-pressure and high-temperature conditions. The material and construction of these flanges allow them to maintain their integrity and performance even in demanding environments.

Stainless Steel Threaded Flanges are manufactured in accordance with industry standards such as ANSI, ASTM, AISI, and EN, ensuring their compatibility and adherence to quality requirements.

Mechanical Property Testing: Used to determine whether the strength, toughness, ductility and other mechanical properties of stainless steel meet the specified requirements.
Chemical Composition Analysis: Quantitative determination of elements on stainless steel samples through spectral analysis, atomic absorption spectroscopy, inductive coupling and other technologies.
Corrosion Performance Test: Common corrosion performance test methods include salt spray corrosion test, acid-base corrosion test and electrochemical corrosion test.
Tensile Strength Test: Through the tensile test, the parameters such as yield strength, tensile strength and breaking strength of stainless steel during the tensile process are measured.
Non-Destructive Testing: Non-destructive testing is used to evaluate hidden defects, cracks and looseness in stainless steel materials. Common methods include ultrasonic testing, magnetic particle testing, eddy current testing, and radiographic testing.
Pressure Test: By exposing stainless steel products to a specific pressure, it is tested whether there are problems such as leakage or deformation to ensure that its pressure resistance meets the requirements.
Surface Quality Test: Used to evaluate the surface flatness, smoothness and oxide layer of stainless steel products.
Welding Performance Test: Check the appearance, mechanical properties and metallographic microstructure of the weld to ensure that the quality of the stainless steel welded joint meets the requirements.
Metallographic Inspection: Through metallographic inspection, the structure, grain size, non-metallic inclusions, etc. of stainless steel are checked to evaluate its quality and performance.
