Understanding Corrosion and Pipe Materials in Plumbing
Corrosion in Plumbing
Corrosion is an irreversible process of degradation affecting the properties of metals and alloys. It impacts all installations made with metal materials.
Types of Corrosion
- Chemical Action: Occurs without an external driving force or electromotive force.
- Purely Chemical Action
- Biochemical Action
External Corrosion
The endurance of piping against external corrosion depends on humidity and certain aggressive building materials like mortar and plaster.
Internal Corrosion
The aggressiveness

Disc Brake Verification
Operation is checked by observing whether the pedal displacement causes the correct movement of the caliper. If not, remove it and repair it. Verify that there are no fluid leaks in the actuator or the hose union. Check the condition of the disc and pads. The pads should be replaced if they are defective. The process of disassembling the pads depends on the brake thickness. The brake pads should be superior to 2mm. When some are defective, all of the pads on the same axle

Steam Production and Distribution
A system of steam production and distribution generally consists of the following items:
- One or more boilers that can burn coal, fuel oil, gas, etc. In industry, fuel oil is often used as fuel.
- The water used must meet certain requirements, according to the rules, requiring the installation of a treatment plant.
- Once treated, the water must pass through a degasser, which removes oxygen and combustible gases.
- Feed pumps are responsible for bringing water from the degasser

Unit 8: Switches and Their Functionality
A switch is a device that can be used to either establish or remove (also called make or break) connections between at least two points in an electric or electronic circuit. The mechanical or electromechanical parts which help the contacts to physically touch and separate are called actuators. A switch can be considered to be a gate which either allows or disallows a certain entity.

Machine Tool Shaping: Components and Operation
Shaping in Machine Tools
Shaping, using a knife or cutting tool and alternative rectilinear movement, begins when the workpiece is set on the machine table.
Parties
Caucus
The body of the machine houses the cutting mechanisms and facilitates progress. It includes horizontal and vertical guides for the movement of the neck and head.
Vertical Slide
Slides along the horizontal guides, enabling alternative rectilinear movement.
Carriage Tilt
Rests on the front of the head and can rotate horizontally. On its
