Patents, Metallurgist

2004/10/17Metallurgist, Vol. 45, Nos. 1–2, 2001 V. M. Samsonov A stand has been developed for a tube cold-reduction mill. The stand includes a crank drive, a stationary housing with two top rolls and two load-bearing rails at the top and bottom of the stand, and a cassette which is connected to the drive and holds two work rolls positioned one above the other. Each work roll has passes and a central

What are the characteristics of plate heat exchanger

Shell and tube heat exchanger is usually manufactured by technology. 8. Simple cleaning operation. The structural plate heat exchanger only needs to loosen the pressing bolts to loosen the plate bundle and remove the plates for mechanical cleaning, which is

Sources: US quietly informed Apple that a Qihoo 360 researcher's iPhone 0-day, which won China's 2018 top hacking contest, was used by China to spy on Uyghurs — An attack that targeted Apple devices was used to spy on China's Muslim minority—and US officials claim it was developed at the country's top

Fully Polymeric Distillation Unit Based on Polypropylene

2021/3/26They have overall heat transfer coefficients of up to 890 W/(m 2 K) []. Another possible use is in the automotive industry as a car radiator. The study [] concluded that PHFHEs are able to achieve comparable results to metal finned tube heat exchangers. ].

Bent tube design used in a high temperature heat

2013/12/4High temperature heat exchanger technology is important with respect to improving the performance of power and propulsion system. This study proposes and optimizes a new heat exchanger tube shape by reducing the size of the tube bundle and improving structural characteristics such as the thermal stress and resonance. Various tube shapes were proposed and a FE analysis was performed

Autoxidation of aromatics

2018/3/28Autoxidation is a conversion pathway that has the potential to add value to multinuclear aromatic-rich coal liquids, heavy oils and bitumens, which are typically considered low-value liquids. In particular, autoxidation of these heavy materials could lead to products that may have petrochemical values, e.g., lubricity improvers and emulsifiers. Proper assessment of an oxidative transformation

Flow Chemistry: Recent Developments in the Synthesis of

2015/11/26Recently, application of the flow technologies for the preparation of fine chemicals, such as natural products or Active Pharmaceutical Ingredients (APIs), has become very popular, especially in academia. Although pharma industry still relies on multipurpose batch or semibatch reactors, it is evident that interest is arising toward continuous flow manufacturing of organic molecules, including

Copper Facts

Copper's thermal conductivity, or capacity to conduct heat, is about 60 percent greater than that of aluminum, so copper can remove much more heat more quickly. The more heat removed from the processor, the more efficiently it will operate, with less potential for damage to other critical components.

US10914527B2

2021/4/4A tube bundle heat exchanger has tubes which are held at each side in tube plates or oval-tube collecting-tube plates and are connected to these in each case by means of a weld seam. The connection of the tubes to the inlet-side tube plate or oval-tube collecting

Water Jet Productivity Starts Here

2017/9/24NLB has been leading the way in water jet productivity since 1971. You won't find a wider range of high-pressure and UHP pump units and accessories anywhere or higher standards of quality and reliability. With in-house engineering, manufacturing and customer

Application of Induction Heating in Food Processing

2016/12/28A heating efficiency of 98% was achieved after including a heat exchanger unit to recover heat from the water used for coil cooling. Fairly uniform heating (within 4.7%) could occur in a centered six-tube bundle. However, non-uniformities could occur in heating

Pool boiling from GEWA surfaces in water and R

Pool boiling heat transfer measurements are reported for water and R-113 with several horizontal cylindrical test sections: plain, T-finned GEWA-T (with various gaps) and standard low fin GEWA-K. With R-113 the enhancement is a well-behaved function ofS T, reaching a maximum of 2 atS T = 0.25 mm. With distilled water, the performance depends in a more complex way on gap width. The maximum
