Welcome to your inquire. Shrimp waist is a tube in elbow, waist elbow very common shrimp, cutting manufacturing is very simple, but the traditional method of large diameter elbow industry now operates the difficult and very difficult to ensure accuracy. Computer graphics can now take advantage of lofting calculated for each pixel length at the point, and then reel in the same number of copies equal parts, in line with the calculated prime intercept length line, cut to draw a line connecting the endpoints. Wall thickness approach: when lofting, first draw the theoretical cut line, and then determine the highest, the lowest point according to the thickness (on the rear bevel) position of the cutting line, then the two connections will be calculated for each pixel line Divisions the length of the roller tube scribing, Group after you can ensure the desired angle. National standards for the S02403 steel pipe fittings building standards. Material is generally carbon steel, stainless steel and alloy steel. In everyday construction, shrimp waist elbow than the original pipe and plate welded elbow using much less. Shrimp waist elbow block by product denominated. Its valuation is based on the weight of it, such as 30 degrees, 60 degrees as well as 90-degree elbow products, or that the price of 90-degree high, the problem that is 90 degrees and more material. 90-degree elbow shrimp is the most expensive. It consists of a tube made of five. 11.25 degrees two, three 22.5 degrees. 11.25x2 = 22.5 degrees. This is the interface of the two ports on. And then to the middle of three 22.5 x3 = 67.5 degrees. Then counted down, it means that the shrimp elbow is 90 degrees. Such sections welded together to form a 90-degree elbow. The shrimp waist elbow 60 degrees then that is composed of three segments. Both sides is 15 degrees, and so was 15x2 = 30. Then in the middle is a 30 degrees, exactly 30 + 30 = 60 degrees of product. 30 degrees is 11.5 degrees by the two tubes and made up.
