Production Information : KAZÁNCSÖVEK, HŐCSERÉLŐ CSÖVEK, ÖTVÖZÖTT CSÖVEK
Kazáncsöveinket elsősorban klasszikus kazángyártáshoz valamint
csővezeték építéshez, hőcserélő berendezésekhez,
erőműi berendezésekhez biztosítjuk. Kazáncsöveink hegesztett és
varratnélküli kivitelben is elérhetőek valamint szénacél
és rozsdamentes (koracél) típusban is.
Kazáncsöveknél is lehetőség van EN/Din szabvány mellett akár
amerikai ASTM/ASME szabvány szerinti beszerzésre is,
valamint szinte az összes anyagminőség elérhető. Kazáncsöveinkhez
széles választékban tudunk kínálni csőidomokat
íveket, edényfenekeket, szűkítőket, karimákat. Kérje ajánlatunkat!

The advantage of steel tubes for precision applications is the high precision of their manufacturing, the good quality of their surface, and the guaranteed mechanical and technological properties. That is why the pipes are widely used in the machining industry and in the automotive industry. Welded pipes for precision applications are manufactured in the process of cold drawing.
