OCTG pipe is connected in order to be run downhole through the use of threaded connections. Generally, there are three classifications of connections: API connections, semi-premium connections and premium connections. API connections are governed by API specifications and are typically the simplest type of connection. Unlike premium connections, API connections may be threaded without restrictions. Semi-premium connections are typically proprietary to each producer and are often designed to be stronger and have higher torque capability than standard API connections. Premium connections, like semi-premium connections, are typically proprietary to each producer and are often designed to be stronger and have higher torque capability than standard API connections. In addition, premium connections employ a hermetic metal-to-metal seal capable of being gas tight. However, there are typically certain threaded restrictions for premium connections.

Dee scanned the hologram map of their intended course, past stars and planets, charting through solar systems, a trajectory that went screen after screen, swiping on and on, refreshing the image repeatedly, but there was just no end to it. She scrolled through the three-dimensional images, examining the predictors for genetic mutation, ran each sequence after the next,checking the computer’s calculations, doing just that, checking on the computer, clicking buttons, dragging icons, the 35th sequence of the day, another 453 species to be verified before she would have to start it again.

"We’re getting close at 6 million meters per second." Em swiped through her Bearing and examined the numbers. "We’re finally beginning to move."

Manufacturers produce OCTG in various specifications, with the requirements typically determined by well complexity and downhole conditions. There are two broadly defined market segments of OCTG: seamless and welded. Seamless OCTG are used primarily in horizontal and directional drilling with longer laterals. Seamless OCTG usually involve more complex manufacturing processes with a greater reliance on proprietary technology. Welded OCTG are mostly used in low-pressure, non-corrosive wells.

Yes and no. The bench press is a static compound movement that moves a barbell through the transverse plane of motion. It’s relatively simple when compared to something like a clean & jerk, but like with most things in strength sports, the devil can be in the details. This article will look at the elbow “tuck” and “flare” concept in the bench press and how to find what will work best for you.

“Establish a trade secret protection plan. Don’t disclose your trade secrets or SOPs in your application. Identify them as trade secrets. You don’t have to describe SOPs in detail. You can also submit a redacted copy (without the trade secrets) to regulators in case they have a public record request. If they insist, you can also submit under seal and designate the trade secret as proprietary. [Editor’s note: Submitting “under seal” in California allows applicants to meet a regulator’s request to disclose the SOP deemed a trade secret, but keeps it protected from public view if there is a public record request. In other words, it is withheld from the public record.]

You should design your wastewater pipes in a similar manner, for the most part. It’s a bad plumbing practice to have a hard 90-degree bend in a horizontal drain line that’s buried in a slab or otherwise hidden. If you have to make a 90-degree bend, use two 45-degree fittings and put a small piece of straight pipe between the fittings, if possible.

On January 3, 2018, OFS International sold us an EMI system for the inspection of pipe for $0.85 million.

After I left home, I would look for Santa Mouse on Mom’s table, and he was always there. His adventures were no more, but he was still a part of Christmas.

14. The OEM Automotive Tools Bolt Extractor Set from Summit Racing Equipment offers you a variety of sizes for a broad range of applications you may encounter. The Bolt Extractor Kit includes five mechanics length right-hand cobalt drill bits and five tapered chromoly left-hand thread extractors. This is all you’re going to need for most fastener extractions.

“When sourcing CO2, look for food grade (99.5 percent pure) or better. To avoid contamination, purchase new, dedicated cylinders that can be refilled by a reputable vendor. Have more cylinders on hand than needed to operate your extractor so you can easily replenish your solvent and avoid downtime.”
