The iron welded pipes of
To do the pipeline for giving it appeared even more difficult, than I for myself represented, the water supply system and gas pipeline device it truly difficult and very responsible business. First it is necessary to choose correctly pipes, now their choice it is simply enormous, and not the descent still can understand, what specifically it is more effective and better than a pipe. If it is required to make the high-quality long-term strong pipeline for giving, better plastic pipes refuse to a descent, they it is cheaper and easier, also it is simpler to establish them, but a krepkost and their firmness very weak. It is most ideal to use for a water supply system and the pipe gas pipeline from metal, is direct I тормознул on a choice of the iron welded pipes covered with zinc. From such pipes I established the pipeline 7 years ago and I will tell to you honest that any troubles with them for all this time was never. Welded iron pipes do pryamoshovny and spiraleshovny, for a water supply system and the gas pipeline for the suburban house I used specifically pryamoshovny pipes. Them do by a method of turning of an iron leaf which then connect a seam placed повдоль pipe.
This seam weakens a pipe a little, though in this case thanks to modern technologies of welding this seam will be had by less krepkost, than a pipe for only 10 % and even least. Properties of welded iron pipes correspond to GOST 3262-75, their length on standards from 4 to 12 meters, a diameter from 10,2 to 165 cm on Russian standards. Such pipes become covered in addition by zinc, thanks to it resistance to corrosion essentially increases, and operational term will be more. Steel is very strong material therefore pipes will have a good krepkost, only that steel is afraid some water therefore the otsinkovaniye which can be made in the diffusive or hot way is carried out it. The welded iron pipes covered with zinc simply неподменны in small town infrastructure also it is very quite often applied in criteria with adverse climate thanks to own significant durability and firmness. Installation of iron pipes quite easy and usual, they simply move to welding and are sharp, but the most important it that pipes of this type are universal and have a large quantity of different applications in construction.
It is possible not to cover pipes of this type even with protective structures and not to paint, in other words as other pipes they do not demand additional protection. Hardness and a krepkost good only in places of seams is required laborious excellent sealing, such pipes can perfectly maintain huge pressure and their main advantage it is big service life and the low price. Naturally, pipes from other materials are cheaper a little, but quality and firmness of the iron welded pipes covered with zinc is quite highest and they ideally work even in extreme criteria.
