Stainless steel pipe is a hollow long round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It also
Molecular modeling includes a series of computational techniques for the creation, manipulation, and representation of various reactions and structures of molecules. Its applications include drug discovery and development but have since expanded to computational chemistry and materials science. Scientists are increasingly using molecular models for various simulations, which can greatly speed up t

In petroleum and natural gas extraction, a X-mass Trees, is an assembly of valves, casing spools, and fittings used to regulate the flow of pipes in an oil well, gas well, water injection well, water disposal well, gas injection well, condensate well and other types of wells. It was named for its resemblance to the series of starting lights at a drag racing strip, called by that name. X-mass Trees
Comparedwith traditional offline teaching, online learning no longer needs to go to aspecific place at a specific time. It only needs an Internet device to startlearning. The use of fragmented time is more efficient, and learners canaccording to their own needs. Set your own learning progress. To a certainextent, online education uses some technological methods and diversifiedteaching methods to m
Surface safety valve (SSV) is a pneumatically or hydraulically actuated fail-safe gate valve for producing or testing oil and gas wells with high flow rates, high pressures, or the presence of H2S. The SSV is used to quickly shut down the well upstream in the event of overpressure, failure, a leak in downstream equipment, or any other well emergency requiring an immediate shut down. Moreover, SSV

Commercial beverage blenders are designed formixing cocktails or other mixed beverage ingredients, which not only canproduce delicious beverages, but also have lower noise. They can easily handleice cubes and crush them to make a smooth, stable drink. The greater the powerof the motor and the better the design of the blades and jars, the more creamythe beverage will be, with almost no ice. After t
Low-code development platforms allow rapid application generation without coding or through a small amount of code. It allows end-users to develop their own applications using easy-to-understand visual tools, rather than the traditional way of writing code. Developers with varying levels of experience can create web and mobile applications by using drag-and-drop components and model-driven logic t
Also known as a service contract, extended warranties are available for some products and services in addition to the standard warranty.
