Pipe Schedule (SCH) is a standard that measures the nominal wall thickness of a pipe, given by the ANSI / ASME B36.10M standard for Stainless Steel Pipe dimensions, and API 5L standard for seamless and welded steel pipes. The pipe schedule number is non-dimensional and depends on the nominal pipe size, internal pipe working pressure, […]
Read MoreYou’ve probably encountered the abbreviation NPS previously on our or similar websites. It means “Nominal Pipe Size,” and it is the North American standard for measuring pipe sizes used for various pressures and temperatures. The NPS standard is widely accepted in the USA, but some things have to be observed correctly in order to find […]
Read MoreThe UK government has decided that the risk of gas fracking is too unpredictable to accept any more, and so they have announced the ban of the controversial well stimulation technique. Officially, the decision was based on the findings of a report by the Oil and Gas Authority (OGA). The report concludes that it is […]
Read MoreApplying heat to metals can make them easier to forge, machine, weld, and fabricate. However, this also brings some issues with it, metals expand when heated, which makes the whole fabrication process more demanding. Luckily, every alloy comes with a predetermined coefficient of thermal expansion. This coefficient shows how much a given alloy will expand […]
Read MoreBack in 1989, the Soviet nuclear submarine K-278 Komsomolets suffered a short-circuit problem in its engine room which resulted in an unmanageable fire problem that quickly spread over adjacent bays, causing the emergency shut down of the reactor. The crew decided to surface and abandon the ship that was still burning ferociously thanks to a […]

Read MoreHave you ever had a shocking experience (pardon the pun) when you received your energy bill? Weep no more. Thanks to the latest NILM (non-intrusive load monitoring) technology, expensive energy and repair bills will soon be something of the past by monitoring the state of electrical appliances. The Concept Often referred to as a “recording” […]
Read MoreRescuers have an extremely hard time getting to the victims of natural disasters. New research from the team at the University of Zurich tackles this very problem. They created a drone that retracts its propellers during a flight to get into tight spaces. How Foldable Drones Work Although technology and safety practices are improving, there […]
Read MoreJimmy Toton, a Ph.D. candidate at the RMIT University in Melbourne, has won this year’s “Young Defence Innovator Award” along with the $15000 money prize that accompanies it. The young engineer has presented a novel 3-D printed steel cutting tool that convinced the judges of its performance by cutting through titanium alloys in a manner […]
Read MoreWeapon systems never seize to evolve into smarter, more effective, and more sophisticated marvels of engineering. In the recent years, the focus has shifted on autonomously flying drones and augmented reality suites, but that’s not all of it. The U.S. Navy is reportedly developing a pioneering watercraft that will be able to get submerged, opening […]
Read MoreThe U.K. is investing $2.65 billion to become the first nation in the world to have a fleet of hi-tech unmanned fighter jets. A full-size model of the U.K.’s proposed next-generation jet fighter, called “Tempest,” was unveiled at the Farnborough International Airshow, held at the Farnborough Airport in Hampshire, U.K., last month. If all goes well, […]
Read MoreDue to our hectic schedules, stress, and a myriad of life responsibilities, most of us suffer from nights without sleep. However, a military secret to help insomniacs fall asleep in just 120 seconds has been revealed. A book titled “Relax and Win: Championship Performance” features this secret method that is said to have a 96 […]
Read MoreThe idea for 3D printing low-cost electronic tattoos on human skin isn’t a new one, however its potential for use in a number of military applications is a relatively cutting-edge proposal. A team of scientists from the University of Minnesota utilized a custom 3D printer to print electronics on human hands, which researchers believe could […]
Read MoreAdverse weather conditions greatly limit the capability of pilots to strike moving targets. This has led to the requirement of an all-weather solution that enhances military capabilities without being affected by conditions on the ground or in the air. Missile maker Raytheon’s StormBreaker bomb will soon provide U.S. Air Force pilots with the capability to […]
Read MoreLockheed Martin has developed a drone-demolishing airborne microwave system which quite literally cooks drones in midair. If that’s not cool enough, the US Army has announced plans to purchase the technology which can be mounted on a myriad of aircraft in order to swiftly disable drones with a beam of focused radiation. Drones are increasingly […]
Read MoreAs a result of a disagreement between the Defense Department and manufacturer Lockheed Martin over who should be the one to fix an F-35 production issue which occurred last year, the Pentagon has suspended acceptance of most F-35 deliveries. “While all work in our factories remains active, the F-35 Joint Program Office has temporarily suspended accepting aircraft […]
