Classification of pipe fitting materials
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 the production method can be divided into push, press, forge, casting and so on.
3. According to the manufacturing standards, it can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard and Russian standard.
4. According to its radius of curvature: can be divided into long radius elbow and short radius elbow. The long radius elbow refers to the outer diameter of the tube whose radius of curvature is equal to 1.5 times, ie R=1.5D; short radius elbow; It means that its radius of curvature is equal to the outer diameter of the tube, ie R = 1.0D. (D is the elbow diameter and R is the radius of curvature).
5. If divided according to pressure level: there are about seventeen kinds, which are the same as the American pipe standards: 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.
