Perspectives of using pipelines from polymer materials during transportation of cast packing filled mixtures pdf

A. Yu. Stovmanenko, A. N. Anushenkov

The purpose of conducted research is the modernization of pipeline transport of cast packing filled mixtures, during underground development of mineral products.
Due to the registered operation problems of steel pipelines in conditions underground workings on process sections of pipeline flushing system a decision to replace steel pipes on more fitting polymer pipes was proposed. In order to determine the more abrasion-resistant type of non-metallic pipelines a few samples of the more common types of plastic and polymer pipelines were selected, additionally comparative testing based on the wearability criterias were carried out. Research was made on the developed test facility of friction. The results of comparitative studies of wearability of such polymer and plastic materials as fiber-glass, polyvinyl chloride, polyethylene of high density and polypropelene that were received with the help of experimental unit showed that pipelines from polyethylene of highdensity PE-100 are the most abrasion resistant. The conducted comparative evaluation of cost of polyethylene pipes with operating pressure of up to 4–6 MPa showed that for today the unit cost of polyethylene pipes almost came close to the cost of steel pipes that are equal in strength and furthermore, considerably lower in cost than similar pipes from other polymer materials and plastic. This allows to assert that on underground loose items of the pipelines for transportation of cast stowing mixtures, where the operating pressure does not exceed 4–6 MPa, using polyethylene pipes PE100 will be more efficient than using steel pipes or pipes from other reviewed polymer or plastic materials.

Keywords: stowing complexes; stowing operations; pipeline transport; polymer pipes; plastic pipes.
