Welding elbow is shrimp "turn", it can be in the pipe or plate cutting after welding and become, and its specifications can be large. The number of nodes and the bending radius are determined by the producer. Welding bending is not very smooth, both of the bending radius is not large, generally about 1 times the diameter of the pipe.
Classification of Welded Bend pipe
Classification of welding elbow, according to its radius of curvature,45 degree elbow
Can be divided into long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the diameter of the tube, that is, R=1.5D. short radius elbow refers to its radius of curvature is equal to the outer diameter of the pipe, that is, R=D. D in the formula is the elbow diameter, and R is the radius of curvature. The most commonly used for 1.5D elbow, if not specified in the contract is 1D or 1.5D, then it is to optimize the use of 1.5D. GB/T12459-2005, GB/13401-2005, GB/T10752-1995., is the most commonly used executive standard in China.
Pressure grade classification
If according to the pressure level, there are about seventeen, and the United States pipe standards are the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS,; Sch 180 degree welding elbow
80, Sch100, Sch120, Sch140, Sch160, XXS, which is the most commonly used STD and XS two. According to the angle of the elbow, 45 degree elbow, 90 degree elbow and 180. Species as a result of the elbow is a lot, when ordering, order is often taken as described in the following methods: such as "LR STD 90 8", said long radius, pressure rating for STD, 90o 8 "elbow; and as," 45 DEG SR XS 4 "said short radius, pressure rating for the XS and 45 degrees of 4" elbow. The above is about the classification of the elbow. Three links, there are two kinds of general. The diameter of the three equal diameter is equal to the diameter of three links, and both ends are the same diameter, but the diameter of the junction is different from that of the other two diameters. The method is as follows: for the equal diameter three links, such as the "T3" three general, the outer diameter is 3 inches and three inch diameter. For different diameter three links, such as the "T4 x 3.5 x three" means that the same diameter of four inch diameter of 3.5 inches of 4 inch diameter. The pressure level is the same as that of the elbow, and the range is the same.
This is the big head, method. Head size of said method is big diameter multiplied by the head diameter, for example "8 x 6" said big head with a diameter of 8 inches and head diameter is 6 inch head size.
