The soil analysis driven fertilization applications are very rare in Turkey and as a result of this situation, so many problems arised in the last decades such as reduction in fertility, soil salinity, reduction in harvest efficiency, and contamination of soil, ground and surface waters due to over-fertilization. Fertilization and irrigation should performed consciously, and soil analysis driven fertilization should become widespread.
In piping applications, metallic fitting parts (nipples) are used to connect plastic pipes. These metallic fitting parts are generally produced by plastic injection technology.Significant quality features for fitting parts can be listed as superior leak tightness and strong durability against exterior torque. If these quality criteria are not met, piping couplings may face leakage problems.
Plastics pipes have higher wall thickness values than film and membrane materials and their gas transport properties should be evaluated using cylindrical coordinates. Due to these aspects, there is no industrial test equipment or standard for determination of gas transport properties of plastic pipes.
Energy is mostly used in buildings in an inefficient way, and even using much more energy, basic thermal comfort conditions are not satisfied. Due to this reason, climating systems should be designed considering energy efficiency and human factor.
The most cost effective way to deliver hydrogen in high volumes is to transport it by pipelines. Currently, hydrogen pipelines are made of stainless steel. These pipes have many disadvantages such as high investment costs, hydrogen embrittlement (causing a shorter lifetime period), rigidity/inelasticity, high hydrogen permeability and hydrogen leakages at the joints. In case of usage of polymer based pipes instead, high permeability of the plastic pipe material arises as a disadvantage.
The aim of the project is to improve structural rigidity of Infrastructure pipes by material and geometry optimization. The final target is the development of optimal profile geometry in order to use 50% less material to have the same structural rigidity.Second stage of the project is the development of mobile production facility for infrastructure pipes, so that pipes can be produced on-site by winding of PE profiles to form this pipe.
