Measuring diameter: measure the outside diameter of main branch
pipe of tee with calipers (outside diameter is measured by
circumferential method) and inside diameter at least 3 points at
each end to ensure that the main outside diameter, inside diameter,
outside diameter of branch pipe and inside diameter meet the
(2) measuring the length of the main pipe: measure the length of
the main pipe of the tee with square ruler and straight ruler, at
least 2 places.
(3) measuring center height: measure the vertical distance between
the branch pipe and the inner slope of the main pipe with a ruler
and a square ruler, and make sure that the center height of the tee
is half of the main pipe's outer diameter.
(4) measurement of bevel Angle: use universal Angle ruler and ruler
to measure the bevel and blunt edge of the main branch pipe end of
the tee, which should meet the design requirements of the drawing.
(5) measurement of skew: place the tee in the bending plate so that
the main branch pipe rests on the bending plate respectively.
Measure the clearance between the bending plate and the end face of
the tee with a ruler or a plug, and the value shall meet the
The three links shall not have cracks, over - burning, overheating
and other phenomena exist, the surface should be no hard point.
The inside and outside surface of the tee should be smooth, without
destructive strength and appearance defects, such as scar, scratch,
heavy skin, etc., after the discovery of defects should be
polished, the thinness of the polished place is not less than the
standard requirements of the wall thickness, polished place should
be smooth and use coloring agent or magnetic powder flaw detection
to confirm the removal of defects.
(3) the root of the three-way branch pipe is not allowed to have
(4) any defects on the tee pipe body shall not be allowed to be
repaired by welding.
