After repairing the spiral seam welded steel pipe, it undergoes non-destructive testing again until it is confirmed that the defect no longer exists, and is rated as qualified. The pipes where the steel strip butt weld and the T-shaped joint intersect with the spiral weld are all inspected by X-ray television or film. Each steel pipe undergoes a hydrostatic test, with radial sealing used for pressure. The pressure and time of the spiral seam welded steel pipe test are strictly controlled by the steel pipe water pressure microcomputer detection device.
螺旋缝焊接钢管经过修补后,再次经过无损检验,直到确认缺欠已经不在存在,评为合格。带钢对焊焊缝及与螺旋焊缝相交的丁型接头的所在管,全部经过X射线电视或拍片检查。每根钢管经过静水压试验,压力采用径向密封。
螺旋缝焊接钢管试验压力和时间都由钢管水压微机检测装置严格控制。试验参数自动打印记录管端机械加工,使端面保持垂直度。同时坡口角和钝边要得到准确控制。
螺旋缝焊接钢管厂家生产螺旋钢管一般都是大批量生产,并且生产的规格多种。那么生产完的螺旋钢管该如何堆放呢?正确的堆放螺旋钢管有利于保护螺旋钢管的质量,延长螺旋钢管寿命,防止变形,被侵蚀。做到有条理的堆放螺旋钢管,也有利于后期螺旋钢管的装车,盘点。螺旋钢管购买者也应该严格按要求堆放螺旋钢管。
