A typical spring-loaded solder sucker A solder sucker partially dismantled showing the spring. A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board.
Prior to the advent of computer-aided design (CAD) in the late 1980s, P&IDs were drawn by hand. The drawing template shown below, actual size 225.mm by 111 mm, is typical of those used to draw P&IDs. Piping and instrumentation diagram manual drawing template (1980s). Symbol key:
Sometime welded pipes are used. Dredge pipe pieces may have different thicknesses, shapes, and lengths, they are also provided with lifting lugs for easy handling. They are supposed to have a smooth surface for low friction. In most cases the flanges are cast together with the pipe to provide a stronger connection between the flange and the pipe.
EAGLE provides a multi-window graphical user interface and menu system for editing, project management and to customize the interface and design parameters. The system can be controlled via mouse, keyboard hotkeys or by entering specific commands at an embedded command line .
The pig itself cannot use GPS as the metal pipe blocks satellite signals. After the pigging run has been completed, the positional data from the external sensors is combined with the pipeline evaluation data (corrosion, cracks, etc.) from the pig to provide a location-specific defect map and characterization.
A pipe support or pipe hanger is a designed element that transfer the load from a pipe to the supporting structures. The load includes the weight of the pipe proper, the content that the pipe carries, all the pipe fittings attached to pipe, and the pipe covering such as insulation. The four main functions of a pipe support are to anchor, guide ...
OpenSCAD is a free software application for creating solid 3D computer-aided design (CAD) objects. It is a script-only based modeller that uses its own description language; the 3D preview can be manipulated interactively, but cannot be interactively modified in 3D.
P.R.Editor Used to create the tracks and other copper features of the board in an external environment to the Design Editor with many more features than the Embedded Router. High-Speed P.R.Editor Allows the user to define a wide range of circuit rules and routing constraints to control the layout process.
