Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, PVC, PPR, RFPP (reinforced polypropylene), etc.
2. The division of manufacturing methods can be divided into pushing, pressing, forging, and casting.
3. The division into manufacturing standards 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 points: can be divided into long radius elbows and short radius elbows. The long-radius elbow refers to the outer diameter of the tube whose radius of curvature equals 1.5 times, ie, R=1.5D; the short radius elbow refers to its radius of curvature equal to the outer diameter of the tube, ie, R=1.0D. (D is the elbow diameter and R is the radius of curvature).
