Soft (or ductile) copper tubing can be bent easily to travel around obstacles in the path of the tubing. While the work hardening of the drawing process used to size the tubing makes the copper hard or rigid, it is carefully annealed to make it soft again; it is, therefore, more expensive to produce than non-annealed, rigid copper tubing.
This hole is sealed with a metal of low melting point that flows away if a predetermined high temperature is reached. The initial use of the fusible plug was as a safety precaution against low water levels in steam engine boilers , but later applications extended its use to other closed vessels, such as air conditioning systems and tanks for ...
Various examples of metal swarf, including a block of compressed swarf. Broken up chips are preferred over stringy drill chips. [1]Metal swarf, also known as chips or by other process-specific names (such as turnings, filings, or shavings), are pieces of metal that are the debris or waste resulting from machining or similar subtractive (material-removing) manufacturing processes.
Vacuum arc remelting (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. [1] The VAR process has revolutionized the specialty traditional metallurgical techniques industry, and has made possible tightly controlled materials used in biomedical ...
Floor drain system in bathroom, Korea. A floor drain is a plumbing fixture that is installed in the floor of a structure, mainly designed to remove any standing water near it. They are usually round, but can also be square or rectangular. They usually range from 2 to 12 inches (5.1 to 30.5 cm); most are 4 inches (10 cm) in diameter.

Sintering begins when sufficient temperatures have been reached to mobilize the active elements in the ceramic material, which can start below their melting point (typically at 50–80% of their melting point [4]), e.g. as premelting. When sufficient sintering has taken place, the ceramic body will no longer break down in water; additional ...
