The pipe mat is laid flat, the nozzle is aligned with the flange neck, the gap is found, and the spot welding is a little. Based on this point, the short side of the square is placed on the tight flange sealing surface, and the long side and the flange thickness are tightly attached. Use a tape measure to measure the distance between the two points on the long side and the centerline of the tube.
How is the butt weld flange assembled with the pipe?
The pipe mat is laid flat, the nozzle is aligned with the flange neck, the gap is found, and the spot welding is a little. Based on this point, the short side of the square is placed on the tight flange sealing surface, and the long side and the flange thickness are tightly attached. Use a tape measure to measure the distance between the two points on the long side and the centerline of the tube. If they are equal, the spot welds corresponding to the points that have been ordered are dead. Start at this point and turn 90° along the circumference of the flange. Use the above method to find the right point, evenly point four points, and the flange is finished.
Straight pipe ends have flanges, and the two flanges are aligned.
First place the tube flat, use the level to find the center line of the tube, and mark the nozzles at both ends. Use a square to find the center line of the corresponding eye on the high neck and flange sealing surface and mark it. Pass the long side of the square from the flange hole, the long edge is close to the inner wall of the flange hole, the short side is aligned with the mark, and the sealing surface is pressed tightly. A little bit is drawn on the groove of the flange neck, and the point is aligned with the pipe. The mark on the port, the two flange eyes are aligned on the pipe.

The wire rope is a helical wire bundle made of steel wires with mechanical properties and geometric dimensions that meet the requirements. The wire rope is composed of steel wire, rope core and grease. A steel wire rope is a rope that is twisted into strands from multiple layers of steel wires, and then a certain number of strands are twisted into a spiral shape with the core as the center. In material handling machinery, it is used for lifting, traction, tensioning and carrying. The steel wire rope has high strength, light weight, stable work, not easy to break the whole rope suddenly, and reliable work. In 1834, European Olubert invented the world's first steel wire rope (smooth steel wire rope).
Wire ropes can be classified according to the material, surface condition, twisting method and purpose of the wire rope.
Classified by material
1. Carbon steel wire rope is made by twisting high-quality carbon structural steel wire as raw material.
2. Stainless steel wire rope, manufactured and twisted with stainless steel wire as raw material.
