20.500.12556/DKUM-47797 Optimiranje rezanja cevnih navojev s prenosnimi napravami Pipe threading optimize with mobile threading machines Optimiziranje rezanja navojev na ceveh v strojnih inštalacijah na podlagi dobrih praks in ugotovljenih dobrih rezultatov na gradbiščih. Rezalniki navojev so prenosne naprave, namensko izdelane za izdelavo cevnih navojev – koničnih ali cilindričnih. Problem, ki se pojavlja, je, da uporabniki rezalnikov ne poznajo vseh dobrih praks in uporabnih postopkov, zato prihaja do napak in kasnejših dodatnih zamudnih popravil na cevnih inštalacijah. V tem delu so predstavljeni optimizirani in pravilni postopki za delo z rezalnikom, opisan in predlagan je novi optimiziran tok materialov in optimizirana organizacija dela in podane so koristne rešitve ter postopki v izogib najpogostejšim napakam. Opisan je zgodovinski pregled razvoja cevnega navoja – angleški Whithworth in ameriški Sellers. Pojasnjena sta standarda, ki sta merodajni na tem tehničnem področju, EN10226-1 in ISO EN228-1, podan pa je tudi pregled teorije rezanja s poudarkom na rezanju navojev na ceveh. Optimizing pipe threading, used in pipe installations, on basis of good practice and positive results, on building sites or workshops. Threading machines are mobile devices, specially made for making of threads - tapered or parallel. Problems, which appear here, are that users of threading machines are not familiar with all proven practices and useful procedures, which results in errors and therefore later expensive and time consuming repairs on pipe installations. In this thesis optimizing and proper procedures for work with threading machine are presented; a recommended optimized flow of materials and work organization are explained, and useful solutions and procedures to avoid most common problems are given. A historic overview of pipe thread is described - English Whithworth and American Sellers. Competent standards EN10226-1 and ISO EN228-1EN10226-1 and ISO EN228-1 in this technical area are explained;and also a review of cutting theory with focus on pipe threading is given. rezanje navojev na cevi rezalnik navojev strojne inštalacije pipe threading threading maschine piping true true false [G.
