The easiest way to materialize the saddle mouth of a large pipe

The easiest way to make a saddle opening for a large pipe is as follows:

1, make a sample by hand or on AUTOCAD, do a good job on the wall thickness, and then make a good sample with linoleum or asbestos sheet;

2, use the sample of the branch pipe, scribe the material on the steel pipe, and then cut it ready to use;

3, the branch pipe (has become saddle-shaped) stuck to want to open the hole, with a stone pen along the edge of the saddle mouth line;

4, if the weld with a single bevel fillet weld, directly according to the drawn line for cutting holes, pay attention to gas cutting "sharp line" angle grasp; if the weld fillet weld, minus the wall thickness, in the interior of the line that has been scratched, draw a cutting reference line evenly, and then cut a line. Uniformly draw a cutting reference line, cutting holes can be.

Diameter 100 pipe riding the mouth of the material:

1, there are special open hole drill.

2, the first hard kraft paper cut out a diameter of 100mm round paper, and then laid on the 150mm pipe along the edge of the line drawn a circle in the gas welding cut (pay attention to cut a little bigger, 100 pipe to insert) and then a short section of 100 pipe welded into a 150X100 tee.

The pipe saddle mouth and reinforcing ring or reinforcing saddle plate opening size, form design, calculation, as well as expanding the size of the sample design is an important job in the design of pipeline processing.

For a long time, the construction site basically used to place the branch pipe in the main tube, using positioning, drawing lines, cutting, grinding, welded to meet the requirements of the molding method of production is completed. The disadvantage of this method is low efficiency, repeated positioning, drawing lines, cutting, grinding operations; main and branch pipe saddle mouth opening edge irregularity; workers labor intensity.

The disadvantage of the manual expansion of the sampling method is that the accuracy is not high, the expansion of the sampling is more cumbersome, inefficient, boring. Through AutoPOL and AutoCAD to realize the pipe saddle mouth, reinforcing ring or reinforcing saddle plate to expand the sampling size design of a way, the method makes full use of today's advanced computer-aided design (CAD) advantage.
