Stainless steel pipe fittings come in various types, each designed for specific applications. Here's a look at the most common types:
Slip-on fittings are easy to install. They simply slide over the pipe ends and are welded into place. These fittings are cost-effective and work well in applications with lower pressure. They're commonly used in plumbing and water systems where ease of installation is essential.
Weld-neck fittings are designed for high-pressure environments. Their extended neck allows for a strong, reliable weld. This makes them ideal for use in oil and gas pipelines, power plants, or chemical processing systems where pressure is a concern. Their strength makes them suitable for heavy-duty applications.
Blind flanges are used to seal the end of a pipe, effectively stopping the flow of liquid or gas. They are crucial in maintenance situations, where sections of the piping system need to be sealed off. Common in power plants and oil refineries, blind flanges prevent leaks and provide easy access for future maintenance.
Threaded fittings are commonly used in smaller pipe systems. They allow for easy connection of pipes without the need for welding. Ideal for systems that need to be disassembled or repaired, these fittings are used in residential and commercial applications, such as HVAC and plumbing systems.
Socket weld fittings are used in systems with small pipe diameters, typically under 2 inches. They are welded inside the pipe, which ensures a smooth flow. These fittings are often used in high-pressure applications, such as in chemical or gas industries, where leakage must be minimized.
Stainless steel is often compared to other materials like carbon steel, PVC, copper, and aluminum. Here's how stainless steel stands out:
