筒体 TubeBody 1.将各筒节按排版图要求组对，各缝分布于0~180°，互错180°，环缝组对间隙0~2mm。 According to the requirements of each tube section layout diagram,combine them, each seam is distributed in the 0 to 180 ° , Stagger 180 ° ,the circumferential seam combination gap is 0 ~ 2mm. 2.组对完毕后，从0°、90°、180°、270°四个方位检测，直线度10%，且不大于4.5mm。.Detect after the combination of the 0 °, 90 °, 180 °, 270 ° four orientation,10% straightness, and no larger than 4.5mm. 3.环缝棱角度控制在δS/10+2，且不大于5mm错边量。 Control the ring slit angular degree at δS/10+2, no larger than 5mm Staggerion of the volume. 4.环缝组对时不可强行组装，可用加减丝扣调节间隙，间隙在0~1.5mm最佳。 When combine the Circumferential seam ,we must not assemble forcibly,use the available subtraction threaded to adjust the gap, the gap is at best in the 0 ~ 1.5mm. 5.确定错边值后，依次从最佳点入手，顺势而成，环缝错边量不得大于1/4δ板厚且不大于2mm。 Determining the value of the Stagger， start from the best point by turn, homeopathy to be it, the circumferential seam should not be than 1/4δ plate thickness and not more than 2mm. 6.对组装后的筒体进行直线度检测，四点方位，其最大差值不得大于4.5mm。Test the straightness after assembling the cylinder, four piont position, the maximum difference is not greater than 4.5mm。 筒体 与 法兰 组对 TubeBodyAndLawOrchidGroupTo 1.法兰必须是经过检验，贴有合格标签的，对应的流水号和产品编号的。 The flange must be tested, labelled with a qualified label, the corresponding serial number and product number. 2.用直尺划出法兰螺栓孔跨中线,与筒体纵缝线平行组装。 Draw the flange bolt holes across the center line with a ruler, assemble and make sure it parallel to the cylinder longitudinal suture. 3.将装一端法兰的筒体,纵缝方向转至90°和270°方位(即水平方向左、右两侧),均分法兰孔,四等分。 Turn the one end installed flange of the cylinder, longitudinal seam direction to the 90 ° and 270 ° azimuth (horizontal left and right sides direction), divided equally flange holes, quartered。 4.用铅垂线或水平尺将有一端法兰的筒体调节好，要求0°~180°跨中线与铅垂线重合。Adjust the one end flange of the cylinder by the plumb line or level ruler, require the 0 ° to 180 ° crossing center line and plumb line to coincide with each other. 5.组对另一端法兰，即管箱法兰铅垂线与跨中等分线要求与上法兰相同条件（即螺栓
