PE Pipe Sleeve with Double Water Ring

PE Pipe Sleeve with Double Water Ring

Sizing Sleeve/ Calibrator

Mainly speaking, the function of the sizing sleeve is to cool down the tube blank of the extrusion die, as well as fix the outer diameter of the tube blank and trim the surface of the tube.

Manufacturing Process Sequence

a. Roughly machine the inner hole with Q235 thick-walled steel pipe, leaving a size allowance for the rough machining inner hole.

b. Drill through holes for true holes.

c. Weld the combined jacket and bulkhead and pipe joints of each inlet and outlet.

d. Annealing treatment to eliminate welding stress.

e. Finish turning the inner hole of the sizing sleeve and the end face of the positioning stop and the inner hole to the drawing size

Precautions for the use of sizing sleeves

a. When installing the sizing sleeve, handle it with care, and do not allow it to hit with a hand hammer to prevent the sizing sleeve from being deformed.

b. Before using the sizing sleeve, carefully clean the surface of the inner hole, burrs and dirt are not allowed.

c. When installing the sizing sleeve, pay attention to the concentricity accuracy of the inner hole of the sizing sleeve and the inner hole of the die to ensure the smooth operation of the sizing, cooling and shaping work of the extruded tube blank.
