THE star child speaks IN light – and you can on the HEAVENLY Keyhole narratives about are listening often to read difficulties which an author may have to find the appropriate Publisher, or as a writer desperate about a blank, white sheet breeds and hair fighting is because the pure white would simply disappear. But who has thought about ever, as actually a book finds its real author? What problems has the book to overcome? What criteria sets it in the correct selection of his Schreiberlings? A book deserves that we once highlighting the concerns and needs, that has to be mastered at the manifestation in the physical world in a bookstore. Book does not equal book is of course… There are so many book characters as there are printed cover. But you can’t book classes with very specific properties. There’s the romantic book, the novel that it loves to swim in an ocean of human tears of emotion, and the heart of the Reader to let languish there, or but the exact chilly science book, its liking it, awesome mental steam to go up in the human brain lard can. Interesting is also the consideration of the notorious Advisor who knows everything better and well intentioned advice showered a man seeking help so that this calls louder confusion only to help. Oh, there are so many different books; and all want to find even the appropriate author…

Also a small book that, curiously all wanted as it is now, was a few years ago: touch the heart of people, convey factual information and give wise advice to name just a few of the possibilities.. Only: How should such a book to find the appropriate author? Most are specialized on a certain Division… In his distress, it used a trick: it saw on Earth quite versatile interested who just desperately thinking about it, What for a birthday card he one he should buy close person. .

Shell and tube heat exchangers tseevt are simple, so-called reverse, the current scheme of coolant in the annulus do not cross partitions, install only one longitudinal septum. In addition to this revised decision on pipe wall thickness, shells, flanges, tube sheets, covers, without reducing their strength (for the whole range of devices). Experience to date operating experience has shown that devices, in contrast to plate heat exchangers are not very sensitive to sudden temperature fluctuations and pressure. Their tube bundles easily and withstand the effects hydroblows, vibration, shaking. All of the standard heat exchangers for heating and hot water are focused on the brass tube with outer diameter of 16 mm and an inner diameter of 14 mm. Brass slightly corroded in a medium boiler and mains water, and a large inner diameter of the tube increases the rigidity of the pipe and facilitates the mechanical cleaning of pipe space. The last circumstance in the recent past was more important considerations of competitiveness and achieve high weight and size performance heat exchangers. It is known that the smaller diameter pipe and the thickness of their walls, the higher utilization rates of mass and volume of the heat exchanger.

Known apparatus with an outer diameter pipe 6.3 or 8 mm, but they cleaning the pipe space mechanically difficult. According to our experts, the construction of shell and tube heat exchanger should allow the pipe to clean the area from pollution deposits of both chemical and mechanical means, pipe and there should be rigid enough to avoid significant deflection after several years of operation. Such requirements are met by pipes with 12 mm in diameter and wall thickness of 1 mm. The accumulated experience of operating devices with a tube allowed us to start later in the wall thickness of 0,8 mm.
