法。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a protective anti-corrosion layer using heat-shrinkable tubes.In general, steel tubes lined with polyethylene or the like are used for transporting fluids such as gas, oil, and water. I'm stuck inside though.
To put an anti-corrosion layer on the welded 4 joints of the gir and e's pipes, the following method has traditionally been used. ?
After inserting, connect the 4 tubes and attach the heating rod.

There were drawbacks such as clutter and stiffness.

Solution 1f41- C: What was done was that the P-collection J-tube was taken to the public and the A-cut 1- thing was observed 9911m outside the carbon-proofing member, and then the point of the 2-tube was made.

As shown, the 1 tangent 1 of the received baggage (2) of A, g, etc.
After covering one part, the overlapped two cut ends of the tube <n 13+, 141? υMouth fever 411 put on, missing the whole tube? The method used is to uniformly heat it, shrink it to the same diameter, and attach it to the connection part six times.
