In the beginning of 2000. on the secondary market only started to be created demand for pipes, used. And this demand gave rise to a strong increase in prices for new tubes. Strong influence on the increase in prices in the pipe industry had Russian mining and metallurgical complex mmc begun to increase prices for metallurgical raw materials and metal, is a staple in the manufacture of tubular products. Will be a huge the difference in price between the new pipe and tube used in the rare little difference in quality, has created a secondary market for tubular products, which today is rapidly developing. The advantage of tubes used – is, above all, their price, which is an order of magnitude different from the price of new. Of course, you may ask, what about the quality, the service life of such a pipe? Most of the designs of the pipes are dismantled long before the exhaustion of the resource, and therefore are useful to reuse. Use of used tubes can significantly save you money. In Russia, the length of trunk gas pipelines is over 200 thousand kilometers. Permanent replacement of these pipes is source of quality used pipes for the secondary market. In finding the weak spots in the pipeline that would avoid catastrophic consequences is replaced by a whole lot. Sometimes the pipes versed on economic reasons. Another important source of aftermarket pipes are surplus stock of various companies. Exporters of pipes – a product pipe mills have not been tested for quality. Pipes used before secondary application usually go through several stages of cleaning and restoration: cleaning the old insulation, cleaning of the inner and outer surfaces of the pipe, if necessary, cutting new facets and various insulating materials. The main problem of pipes were in use is that after recovery there is not any certificate. Used tube recommended for use in designs that require much less strength than has the same new pipe. That is, in important and critical structures using tubes used can not. But it will be correct, if applied in designs that do not require a large margin, and the use of new pipe simply is not profitable (sewers, piles, poles, etc.). Meanwhile, the aftermarket tubular successfully developed, and become a competitive business. In the near beduyuschemne a decrease in demand for pipes, Second-hand, but rather on the contrary only increase. As this contributes to a constant increase in prices for new tubes.
