Sch40 7D Butt Weld Micro Exhaust Carbon Steel Pipe Fitting Bend
According to the manufacturing method, pipe fitting bend can be divided into pushing, pressing, forging and casting.
According to the manufacturing standards, pipe fitting bend can be divided into national standard, electrical standard, ship standard, chemical standard, water standard, American Standard, German standard, Japanese standard, Russian standard, etc.
Pipe fitting bend can be divided into long radius bend and short radius bend according to curvature radius. Long radius bend refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, i.e. r = 1.5D; Short radius bend means that its radius of curvature is equal to the outer diameter of the pipe, i.e. r = 1.0d( D is the bend diameter and R is the radius of curvature).
According to the pressure rating, there are about 17 kinds of bends, which are the same as the American pipe standards, including: sch5s, sch10s, sch10, sch20, sch30, sch40s, STD, sch40, sch60, sch80s and XS; Sch80,SCH100,Sch120,Sch140,Sch160,XXS; The most commonly used are STD and XS.
