When polyurethane insulation, why should use stainless steel wire or steel band fixed?
When the pipe is cold, the pipe protection layer may have condensed water, and the wire is easy to rust.
According to the branch pipe and the insulation shell position, determine the shape of cutting polyurethane pad, and then use the stainless steel wire to fasten, after taped.
When the pipe is vertical or with an angle not greater than 45 degrees, the bearing ring shall be provided. The width of the bearing ring steel belt shall be 2/3 of the thickness of the insulating layer. Set one every 2 meters.
