Description
Technical field
The utility model relates to the UT (Ultrasonic Testing) technical field, particularly a kind of appearance pipe that adopts the UT (Ultrasonic Testing) technology that small-caliber steel pipe inwall transverse defect is detected.
Background technology
Because small-caliber steel pipe transverse inner wall defective flaw detection appearance pipe cross machine inwall artificial defect is difficulty relatively; Can not adopt the UT (Ultrasonic Testing) technology that internal diameter is carried out carrying out flaw detection less than the small-caliber steel pipe transverse inner wall defective of 25mm; As stipulating among the GB/T5777-2008: when internal diameter cross machine inwall artificial defect not during less than 25mm, this that is to say and need not carry out the flaw detection of transverse inner wall defective to internal diameter less than the small-caliber steel pipe of 25mm.
Along with the steel pipe final user improves constantly the requirement of tube quality; By act.std internal diameter is not carried out the requirement that the inner wall defect flaw detection can not have been satisfied the user less than the small-caliber steel pipe of 25mm; Therefore need a kind of appearance pipe that small-caliber steel pipe inwall transverse defect is detected, and serve as to demarcate benchmark internal diameter is detected a flaw less than the transverse inner wall defective of the small-caliber steel pipe of 25mm with the appearance pipe.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art and a kind of appearance pipe that adopts the UT (Ultrasonic Testing) technology that small-caliber steel pipe inwall transverse defect is detected is provided.
The technical scheme of the utility model is: a kind of small-caliber steel pipe transverse inner wall defective flaw detection appearance pipe, form by the first semicircle short tube, the second semicircle short tube and parent pipe.Inwall at the first semicircle short tube is provided with transverse defect, and the degree of depth of transverse defect and width are processed according to the UT (Ultrasonic Testing) examination criteria.Be provided with vertical bevel for welding at the first semicircle short tube with the end face that the second semicircle short tube is connected; Be provided with the annular solder groove at the first semicircle short end face that is connected with the parent pipe; Be provided with vertical bevel for welding at the second semicircle short tube with the end face that the first semicircle short tube is connected; The end face that is connected with the parent pipe at the second semicircle short tube is provided with the annular solder groove, and the first semicircle short tube and the second semicircle short tube are through being welded to form a pipe.Be provided with annular solder groove with the first semicircle short tube with the end face that the second semicircle short tube is connected at the parent pipe; The parent pipe and the first semicircle short tube and the second semicircle short tube are connected as a single entity through welding through the pipe that is welded to form, and the parent pipe and the first semicircle short tube and the second semicircle short tube are on the same axis through the pipe that is welded to form.
The length L of the described first semicircle short tube and the second semicircle short tube is 220-260mm.
The utility model compared with prior art has following characteristics:
The small-caliber steel pipe transverse inner wall defective flaw detection appearance pipe that the utility model provides is easy to process, has satisfied the requirement of internal diameter being carried out the flaw detection of transverse inner wall defective less than the small-caliber steel pipe of 25mm.
