Compared to Stainless Steel Flanges

PN100 steel flanges are less expensive than stainless steel flanges but may not be as corrosion-resistant.

Where to Buy PN100 Steel Flanges

PN100 steel flanges are available from various suppliers and manufacturers. Buyers can find them online or through industrial supply stores.

FAQs

What is the pressure rating of PN100 steel flanges?

PN100 steel flanges have a pressure rating of 100 bar, which means they can withstand a maximum pressure of 100 bar (or 1450 psi) at a temperature of up to 120°C (or 250°F). This pressure rating is suitable for high-pressure applications, such as in oil and gas pipelines, chemical plants, and power generation facilities. It is important to ensure that the flange material and design are suitable for the specific application and operating conditions to prevent failure and ensure safety.

Can PN100 steel flanges be used in low-pressure applications?

Yes, PN100 steel flanges can be used in low-pressure applications, but they may be over-engineered for such applications.

What is the manufacturing method for PN100 steel flanges?

PN100 steel flanges are typically manufactured using forging, casting, or machining methods.

How often should PN100 steel flanges be inspected?
