ANSI/ASME B16.5 Class 300 Stainless Steel Slip-On Flanges:
ANSI/ASME B16.5 Class 300 stainless steel slip-on flanges are widely used for connecting pipes, valves, pumps, and other equipment. These flanges offer excellent corrosion resistance and durability, making them ideal for environments with high pressure and temperature requirements.
The design of the stainless steel slip-on flange allows it to slide onto the pipe and then be secured by welding both inside and outside. This design makes it easier to install compared to other flange types, such as weld neck flanges. The Class 300 rating indicates that the flange can withstand up to 300 pounds per square inch (psi) of pressure, making it suitable for piping systems within specific temperature ranges.
The advantages of slip-on flanges include cost-effectiveness, as they are relatively inexpensive to manufacture and install. They are also easy to install and align, especially in systems that require frequent disassembly and reassembly. Additionally, the stainless steel material provides excellent corrosion resistance, making these flanges suitable for use in harsh environments such as chemical plants, water treatment facilities, and offshore platforms.
These flanges are commonly used in industries such as oil and gas, chemical processing, water treatment, and marine applications. In these industries, Class 300 stainless steel slip-on flanges ensure the stable operation of piping systems with their high pressure-bearing capacity and high-temperature resistance. As a result, they are the ideal choice for industrial applications requiring high pressure, temperature, and corrosion resistance.

The manufacturing process of ANSI B16.5 Class 300 slip-on flanges:
First, high-quality stainless steel materials such as 304, 316, and 316L are selected for their excellent corrosion resistance, strength, and ability to withstand high-pressure environments. The selected steel is then heated and subjected to pressure to undergo forging, which forms the initial shape of the flange. This step ensures material uniformity, enhancing the strength and durability of the flange.
After forging, the flange undergoes precise machining processes such as turning, milling, and drilling to ensure that the outer diameter, inner diameter, and bolt holes meet the ANSI B16.5 Class 300 standard. Special attention is given to the precision of drilling the bolt holes and machining the flange face (such as raised face or flat face). For slip-on flanges, the precision of the inner diameter is crucial to ensure the flange can easily slip onto the pipe and be welded on both the inside and outside after installation.
During heat treatment, the flange is heated and cooled in a controlled manner to eliminate internal stresses formed during forging and machining, while also enhancing the material's mechanical properties and corrosion resistance. Surface treatments such as pickling or passivation are carried out to remove oxides and impurities, ensuring a smooth surface and improved corrosion resistance.
After manufacturing, each Class 300 slip-on flange undergoes rigorous inspection and testing to ensure it meets the ANSI B16.5 standard. These tests include dimensional checks, visual inspections, non-destructive testing (such as ultrasonic testing and dye penetrant testing), and pressure testing to ensure the flange can withstand the specified pressure.
After passing all inspections and tests, the flange undergoes final finishing, including cleaning, coating (if required), and packaging. During packaging, the flange is coated with protective oil or paint to prevent corrosion during transport and storage.
Through these steps, manufacturers ensure that the ANSI B16.5 Class 300 slip-on flange meets the high performance and safety standards required in industrial applications such as oil, gas, petrochemical, and power industries.
Grades of Stainless Steel Flanges:
Common materials for stainless steel flanges include different grades such as 304, 316, 430, 410, and 2205. 304 and 316 offer good corrosion resistance and are widely used in the chemical, food, and marine industries, with 316 being more resistant to chloride corrosion. 304L and 316L are low-carbon versions suitable for welding applications. 430 is a ferritic stainless steel used in mild corrosion environments, such as automotive exhaust systems and household appliances. 410 is known for its high hardness and wear resistance, often used in industrial applications. 2205 and 2507 are duplex stainless steels, suitable for more demanding environments such as seawater and oil and gas industries. The choice of grade depends on the specific requirements to ensure the flange performs well in its intended environment.

| Austenitic Stainless Steel | 304, 316, 310 | High corrosion resistance, non-magnetic, good formability and weldability, high-temperature oxidation resistance | Food processing, medical equipment, kitchenware, chemical industry, marine environments (especially 316) |
| Ferritic Stainless Steel | 430, 446 | Magnetic, good corrosion resistance, moderate strength, not as formable as austenitic stainless steel | Automotive parts, kitchen appliances, industrial equipment |
| Martensitic Stainless Steel | 410, 420, 440 | Magnetic, high strength and hardness, lower corrosion resistance, can be heat treated for hardness | Cutlery, tools, surgical instruments, high-strength industrial parts |
| Duplex Stainless Steel | 2205, 2507 | Mixed structure of austenite and ferrite, high strength, excellent resistance to stress corrosion cracking, pitting, and crevice corrosion | Oil and gas, marine applications, chemical processing |
| Precipitation-Hardening Stainless Steel | 17-4 PH, 15-5 PH | High strength, good corrosion resistance, different mechanical properties through heat treatment | Aerospace, military, high-performance engineering |
| Ferritic-Austenitic Stainless Steel | 2507 (Super Duplex Stainless Steel) | Excellent corrosion resistance, high strength, resistance to chloride-induced stress corrosion cracking | Extreme environments, such as seawater, chemical processing, offshore industries |
| High-Alloy Stainless Steel | 904L, Alloy 20 | Extremely high corrosion resistance, especially in acidic environments, can withstand extreme conditions | Chemical processing, power generation, petrochemical industries |
