Review ZORO SELECT Pipe Flange Lap Joint 304/304l

The Zoro Select 4381000270 pipe flange is a high-quality lap joint flange designed for use in piping systems with a 304 and 304L (stainless steel type 304 and type 304L) pressure rating. This flange is specifically engineered for lap joint applications, where the flange faces are brought into contact and sealed by the adjacent flange or by gaskets.

This Zoro Select pipe flange is manufactured using advanced techniques that ensure precise dimensions, excellent surface finish, and consistent material properties. The flange features a raised face design with a diameter of 12 inches (304.8 mm) and a bore diameter of 11.75 inches (298.44 mm), making it suitable for piping systems with a nominal pipe size of 12 inches (300 mm).

The flange body is made of 304L stainless steel, which is known for its excellent corrosion resistance and strength. The material is resistant to a wide range of chemicals and environments, making this flange an ideal choice for use in applications involving aggressive chemicals, high temperatures, or other harsh conditions.

The flange is also designed with a raised face height of 1.5 inches (38.1 mm) and a bolt circle diameter of 20.3 inches (515.2 mm). This bolt circle diameter is suitable for 8 ANSI 150# bolts, which are not included in the purchase of the flange. The flange is designed in accordance with ANSI B16.5 and ASME B16.5 standards.

This Zoro Select pipe flange is a lap joint design, which means it is designed for use without a gasket between the pipe and the flange. Instead, the flange faces are brought into contact and sealed by the adjacent flange or by other means, such as welding or threaded connections. This design can provide a more robust seal and improved leak resistance compared to gasketed designs, making it an excellent choice for high-pressure or high-temperature applications.

Overall, the Zoro Select 4381000270 pipe flange is a durable, high-performance lap joint flange that is suitable for use in piping systems with a 304 and 304L pressure rating and a nominal pipe size of 12 inches (300 mm). Its excellent corrosion resistance, precise dimensions, and consistent material properties make it an ideal choice for use in harsh environments and demanding applications.
