Background

Ships sailing at sea, oil and gas drilling platforms, oil refineries and oil refineries on offshore and near-shore islands all use stainless steel as a typical steel pipe material, but all have a common corrosion problem, namely corrosion is divided into two types, namely pitting corrosion and crevice corrosion. The corrosion point or surface is generated by the motion friction between the pipeline and the pipe clamp or other hard objects, the friction is generated by the dynamic environment of the sea bottom and the sea water, the consequences caused by corrosion damage of the pipeline are serious due to earthquakes, ocean currents and the like, and the economic loss and the fault finding difficulty in maintenance are extremely high.

Pitting and crevice corrosion exist between steel pipes and pipe stands, in pipe clamps, between adjacent steel pipes, and below contamination and deposits that may accumulate on the steel pipe surfaces. Tight gaps pose the greatest risk of crevice corrosion. In a gap, corrosion of the steel pipe may result in a decrease in the oxygen concentration in the flow in the gap. The lower oxygen concentration increases the likelihood of oxide film breakdown at the passivated surface, thereby corroding to form shallow pits.

Most of the existing pipe clamps are of wafer type structures, and the existing pipe clamps are of half-packaged or full-packaged structures, so that the contact area is large, and the corrosion resistance is poor. In addition, the existing pipe clamp can only clamp a pipe with one pipe diameter, when the pipe clamp clamps pipes with different diameters, the pipe clamp pipes with different specifications need to be matched, the adaptive capacity is poor, and the practicability is not enough.
