Steel Standards
ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.

How Strong is PVC Pipe? (With PVC Strength Charts)
· The above is a question very commonly asked. While it may seem like a simple question, how to define the strength of PVC pipe is far from straightforward. The term "strength" can mean a number of things, all of which cannot be covered in one blog post. The three types of strength measurements I will go into in this post are collapse pressure, burst pressure, and tensile strength. .

The Pelleting Process
pressure. No excuse, however, exists today for the uninformed pellet mill operator. The science of grain processing has now reached a point that, by knowing the characteristics of the feed (moisture, content, fiber, etc.) and using machinery with accurate measurements, the guesswork has been removed from pelleting. As a result, much more is required of the pellet mill operator in the way of ...

Wave power
Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC).. Wave power is distinct from tidal power, which captures the energy of the current caused by the gravitational pull of the Sun and Moon.

Tackling Titanium: A Guide to Machining Titanium and Its ...
· The next hurdle to consider is that titanium has a strong tendency to adhere to a cutting tool, creating built up edge. This is a tricky issue which can be reduced by using copious amounts of high pressure coolant aimed directly at the cutting surface. The goal is to remove chips as soon as possible to prevent chip recutting, and keep the flutes clean and clear of debris. Galling is a big ...
