Description
Technical Field
The utility model relates to a heat exchange tube end cap of hydrogen energy field heat exchanger.
Background
The heat exchanger is more and more widely applied in the field of hydrogen energy, in the heat exchanger, a heat exchange tube is particularly important as a main part of the heat exchanger, so that the service life of one heat exchanger is determined by the service life of the heat exchange tube, but the heat exchange tube is prone to leakage due to corrosion, abrasion and the like along with the increase of the operation time, and for the heat exchanger which cannot be replaced, the tube blocking is allowed, but the number of the tube blocking is not more than 1% and the total number is not more than 2, so that the tube blocking mode is often adopted for the continuous operation of the heat exchanger.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a plug of hydrogen heat exchanger heat exchange tube.
The technical solution of the utility model is that: the utility model provides a hydrogen heat exchanger heat exchange tube end cap, includes heat exchange tube, end cap, welding seam, end cap thickness be 40mm, both ends are equipped with the chamfer, end cap inner end chamfer be 2 x 45, end cap outer end chamfer be 5 x 45, the end cap external diameter corresponding with the internal diameter of heat exchange tube, welding seam tip flush with the heat exchange tube tip, thickness is 2mm.
The utility model has the advantages that: simple structure, high pipe plugging success rate and convenient operation.
