Abstract

PROBLEM TO BE SOLVED: To provide a pipe airtightness test apparatus capable of easily performing an airtightness test of a metal pipe pipe body and sealing the pipe body so as not to damage a product to be inspected. SOLUTION: In order to close an opening of a metal pipe pipe body 1, a pipe body clamp left 2 and a pipe body clamp right 3 are engaged with the metal pipe pipe body 1. The upper lid slide type packing tightening jig 4 formed on the outer circumference of the tube clamp left 2 and the tube clamp right 3, and the tube clamp slide formed on the inner circumference of the upper lid 8 and having an oblique rotation direction. Fit the type packing tightening jig 5. The upper lid 8 is fitted and rotated, and the pipe body clamp slide type packing tightening jig 5 comes into contact with the upper lid slide type packing tightening jig 4, slides and locks at an oblique portion, and the metal pipe pipe body 1 is the upper lid 8. It is pressed against the inner packing 7 to seal the inside of the metal pipe body 1. [Selection diagram] FIG. 8

Description

  The present invention relates to an airtight test of a welded portion of a metal pipe tube.

The problem to be solved is that the welded part connecting the metal pipe tube and the joint can be hermetically tested, and the metal pipe tube and the joint are easily sealed so as not to damage the product under test. It is what makes it possible.

The present invention superimposes the doughnut-shaped tube clamp left, tube clamp right and upper lid on the convex part (bloating treatment) formed on the tube, and without excessive force on the metal pipe tube. It is characterized in that the pipe tube opening can be sealed.

The hermetic device of the present invention has an advantage that it enables a hermetic test of a welded part of a product in which the metal pipe tube is opened, and it is simple and not damaged.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  First of all, the metal pipe pipe body uses a product that has been bloated. As shown in FIGS. 1 and 2, the metal pipe tube 1 is disposed in the center, and a tube clamp left 2 and a tube clamp right 3 are disposed on both sides thereof.

  As shown in FIG. 4, the tube clamp left 2 and the tube clamp right 3 are engaged. Further, a tube clamp left 2 meshed with the metal pipe tube 1 and a tube clamp right 3 are fitted with an upper lid 8 as shown in FIG. 5, and an upper lid handle 9 or a handle or a round bar is used. By rotating and locking as follows, the inside of the metal pipe tube 1 is sealed.

In a sealed state, it can be confirmed that air pressure is applied from 15 of FIG.

  According to this document, after installing a tube air tightness test apparatus on the metal pipe tube body, the weld is inspected by applying pressure from the opening through the air pressure inlet 15 of FIG.

Further, it is assumed that an airtight test is performed even when pressure is applied from the pipe body airtightness test apparatus side of the metal pipe body, 13 in FIG.

  By performing the test with the tubular body hermetic test apparatus, the workability can be improved and the hermetic test can be performed safely and without damaging the metal pipe tubular body.

Claims (1)

In order to close the opening of the metal pipe tube 1, the tube clamp left 2 and the tube clamp right 3 are engaged with the metal pipe tube 1, and the upper cover 8 of the tube clamp 1 is further fitted. By rotating the upper lid handle 9 or the handle and sliding and locking the oblique portions of the upper lid slide type packing fastening jig 4 and the tube clamp slide type packing fastening jig 5 in FIG. A device that seals the inside of the body.
