Abstract

PURPOSE:To provide the titled quatrz glass tube capable of manufacturing Xe lamp lumionus tubes, optical fiber reinforcing materials, etc. having uniform shape, diamter, etc. without causing irregular temp. spots in heating with an oxyhydrogen flame or the like by specifying the thickness ratio and ununiformity degree of a quartz glass tube. CONSTITUTION:This thick-walled transparent quartz glass tube of high accuracy has 5-50mm. outside diameter, avrage inside diameter (d) represented by equation I (where D is average outside diameter of the tube and f is -0.2D+2.5 in case of 5<=D<=20 and -0.3D+6 in case of 20<D<=50), and wall thickness accuracy over 300-1,500mm. length satisfying equation II (where alpha is differnece between the maximum and minimum valuse in inside diameter).
