60 degree pipe elbow

SPECIFICATIONS

60 degree pipe elbow

Elbow is in the piping system, connecting two of the nominal size of the same or different pipe, so that the pipe to make a certain angle to turn the pipe. Elbow classification: According to the angle, the most commonly used have 45°,90° and 180°, in addition, according to the engineering needs, including 60 degree pipe elbow and other abnormal angle elbow.The way to connect with the pipe is: direct welding (the most commonly used method), flange connection, thread coupling has socket-type coupling.

Classification of Elbow:  
  1. Material Division of carbon Steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, Argon Luo lek, pvc,ppr, RFPP (Reinforced polypropylene) and so on.   
2. The Division of production methods can be divided into push system, repression, forging, casting and so on.  
  3. The Division of manufacturing standards can be divided into GB, electric standard, ship, Standard, Water-mark, American Standard elbow, German standard, Japanese standard, Russian standard and so on.
4. According to its radius of curvature to divide: can be divided into long radius elbow and short radius elbow. A long radius elbow is the outer diameter of a pipe that is equal to 1.5 times times its radius of curvature, i.e. r=1.5D. A short radius elbow refers to its radius of curvature equal to the outer diameter of the pipe, i.e. r=1.0D. (D is elbow diameter, r is radius of curvature).
5. If according to the pressure grade: about 17 kinds, and the United States pipe standards are the same: 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 two species.  
6. According to different shapes and uses can be divided into: groove-type elbow, card sleeve elbow, double bearing elbow, flange elbow, different diameter elbow, elbow elbows, internal and external teeth elbow, punching elbow, push elbow, socket elbow, butt welding elbow, internal wire elbow.
7. According to the angle of the elbow, there are 45° elbow, 90° elbow and 180° elbow. 8. According to the radius of curvature to divide, can be divided into long radius elbow and short radius elbow. A long radius elbow is a pipe diameter equal to 1.5 times times its radius of curvature, i.e. r=1.5D A short radius elbow refers to its radius of curvature equal to the outer diameter of the pipe, i.e. R=D. where Dis the elbow diameter, R is the radius of curvature.

Elbow Technical Requirements:
1. As most of the pipe used for welding, in order to improve the quality of welding, the end of the Cheng Chengpo mouth, leaving a certain angle, with a certain edge, this requirement is also relatively strict, the edge of how much thickness, the angle of the number and deviation range are stipulated. The surface quality and mechanical properties are basically the same as the tubes. For the convenience of welding, the tubing is the same as the steel of the connected pipe.
2. All the fittings must undergo surface treatment, the internal and external surface of the iron oxide skin through shot peening treatment, and then coated with anti-corrosion paint. This is for export needs, moreover, in the domestic also for the convenience of transportation to prevent corrosion oxidation, must do this work.
