Product details

90 degrees elbow is a common type of elbow, because it needs to connect the pipe fittings, only master 90 degree elbow specification can guarantee the use。 90 degrees bend bend is kind of a different Angle, other common and 45 ° and 180 °, in addition, according to the requirements of the project also includes 60 °, and other abnormal Angle bend。 The bent material has cast iron, stainless steel, alloy steel, calcined cast iron, carbon steel, nonferrous metal and plastic etc。

90 degree elbow for pipe fittings, pipe fittings. It is used in the branch of the main pipeline. Connect two of the nominal sizes of the same or different pipes to make the pipeline change in a 90-degree direction. The way to connect the pipe is: direct welding (commonly used) flange connection, thread connection and socket connection.

90 - degree bend forming the basic process is: first, a cross section welding for polygon or both ends closed multi multi ring shell fan shell, internal filled with medium pressure, with inner pressure and internal pressure under the action of cross section of polygonal gradually became round, and eventually become a circular ring shell. According to the requirements, a circular ring shell can be cut into four 90-degree elbows or six 60-degree elbows or other specifications. The process is suitable for the diameter of the bend and the inner diameter of the elbow is greater than 1. 5. Any size of the large elbow is the ideal method for making large pressure bends.

The 90-degree bend

The plate gold expansion pattern generally adopts the phase - line method to release the sample, without the calculation formula. Drawing software is more convenient to draw.

It's called the "shrimp rice waist".

90 degree Angle manual lofting step:

山东群英会怎么玩1. Draw the side projection of the elbow with the actual dimension first. Include seam lines.

2. The 90 degree elbow is divided into independent shapes by line. (you can cut it or you can draw it separately.

To come up with a pattern, 3, 90 degrees (set the center line of the vertical) on the other a piece of paper, draw two parallel up and down along the height of horizontal line, and with the center line of the vertical, the length is the circumference of the pattern in diameter. (closed rectangle)

4, 90 degrees will be uniform pattern vertical direction, and the tag, and then these bisectrix vertical painting just draw a rectangle, must pay attention to the points on the graph corresponding to the projection point on the pattern.

5. 90 degrees will be equal points along the horizontal direction of the drawing. Parallel to the drawing of the unfolding pattern and corresponding points. The intersecting circular connection that is obtained from the unfolding sample is the unfolding curve. The more dense the contour, the more accurate the curve.
