Those in the oil well drilling business use tally books continually every day. They
keep a close record of when they attach a new section of pipe, and how long it is, and what time it is. The books are just the right size to fit into a pocket, so the books are kept right where they are needed. So tally books are a necessity in the oil drilling business.
To protect the book from weather and abrasion, the cover is made of vinyl. That’s where the irony hits. Vinyl is a man-made fabric made from OIL!
It was developed only in 1920 as an inexpensive durable fabric that is easy to make. It is made out of oil and salt, and its real name in poly vinyl chloride.
Here are the details for you scientists:
They break down petroleum using high pressure and temperature. This is called cracking. The results are ethylene, butadiene, propylene, and a few other things. They combine salt (a source of chlorine) with the ethylene using “electrolytic disassociation”. They add a few other compounds and end up with poly vinyl chloride (vinyl).
As you know, vinyl is ubiquitous, and very inexpensive. However, it looks expensive, similar to leather.
The quintessential picture of a beautiful autumn day is no doubt one that includes warm-hued foliage. As the days begin to grow longer, you will most likely need to carry around your promotional maglights in the evening hours- especially in order to illuminate the beautiful leaves in your neighborhood. This week is Fall Foliage Week, so grab your high-quality, dependable promotional maglights and find your favorite tree to spotlight!
What is the “average” diameter of a pipe? This term would come into play only if the pipe is not exactly round in cross section.
If the pipe were deformed and flattened out, what would be the diameter of it? It would have a long diameter and short diameter. So how would you determine its original diameter?
Instead of using a caliper or micrometer and doing
some kind of calculation, you can do it the easy way. Use a pipe diameter tape measure. It will easily tell you what the original, or average, diameter is. Just wrap it around the pipe, and read off the “original” or “average” outside diameter.
This week (the 3rd week of September) is National Construction Appreciation Week. Construction covers a wide array of activities. Building bridges, razing barns, pouring concrete, painting buildings, covering roofs, making highways, installing drywall, and pounding nails, are all part of the picture of building our environment.
It helps to measure the size of things on a blueprint. The 2 common configurations are 1/4″ and 1/8″. On the 1/4″ scale, each mark is 1/4″ apart, and numbered from zero, 1, 2, 3, 4, etc. If the blueprint is drawn to that scale, then the “5” mark on the scale means 5 feet, or 5 miles, or whatever the blueprint says.
Every year on September 15, people worldwide join to celebrate Greenpeace Day. They come together to fight for a better world and to raise awareness about conserving and preserving our environment.
How can we all come together to support this cause? -Meet with your local activist group -Order engraved flashlights with “Greenpeace Day” -Talk about environmental concerns with your neighbors, family, and friends
Sunday is National Grandparents Day. Chances are, the gray side of the family is having trouble seeing at night. They may even have trouble seeing in the daytime. What better gift, than a Maglite engraved with “I Love you Grandma”, or “You’re the Best Grandpa”.
Unfortunately, there are none in stock anywhere. Lufkin doesn’t even have any.
They have continually moved back their ship date since January 2022. At this point, I won’t be happy until they tell us that they shipped us some tapes.
I don’t know whether it is a raw material shortage, labor shortage, or otherwise. This problem has existed for 12 months now. I can’t imagine what the problem might be with Lufkin/Apex.
Yes. Definitely. The Pi-Cobra tapes are an excellent substitute. The T217-6654 measures pipe diameters up to 38 inches, in 100ths of an inch. Your imprint can even be put on both sides of the case, at an extra charge. It is also available in metric scale (T217-6657).
