What Is a Flanged Pipe?

Flange fittings are a type of welded fittings. Such fittings are used to match pipes. Some are processed and some are unprocessed. Some castings are cast together with the flange. Welding is done in post processing. It can be processed in the factory, as well as at the construction site. There are big and small flange fittings, but also elbow and tee flange fittings. Its material is also various, including carbon steel, alloy steel, stainless steel and so on.

1. Divided by material:

Carbon steel: ASTM / ASME A234 WPB, WPC

Alloy: ASTM / ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911, 15Mo3 15CrMoV, 35CrMoV

Stainless steel: ASTM / ASME A403 WP 304-304L-304H-304LN-304N

ASTM / ASME A403 WP 316-316L-316H-316LN-316N-316Ti

ASTM / ASME A403 WP 321-321H ASTM / ASME A403 WP 347-347H

Low temperature steel: ASTM / ASME A402 WPL3-WPL 6

High-performance steel: ASTM / ASME A860 WPHY 42-46-52-60-65-70

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, PVC, PPR, RFPP (reinforced polypropylene), etc.

2. Divided by production method, it can be divided into pushing, pressing, forging, casting and so on.

3. According to the manufacturing standard, it can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.

4. According to its curvature radius, it can be divided into long radius elbow and short radius elbow. The long radius elbow refers to the outer diameter of the pipe whose curvature radius is equal to 1.5 times, that is, R = 1.5D; the short radius elbow refers to its radius of curvature equal to the outer diameter of the pipe, which is R = 1.0D. (D is the elbow diameter and R is the radius of curvature).

5. If divided by pressure level: there are about seventeen types, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; the most commonly used are STD and XS.
