Novel Design

There is an increasing demand for submarine pipelines which can transport highly corrosive products. Due to the significant cost of solid stainless steel pipes, the interest in more economical mechanically lined pipes (i.e. carbon steel pipes lined with a thin stainless steel layer) is growing. There is further incentive to combine this technology with the highly efficient reel-lay method, which is an alternative to the S-lay and J-lay methods for installation of small to medium size steel submarine pipelines. Reeled pipelines, however, are subjected to at least two symmetrical plastic strain cycles during installation. The plastic straining associated with reeled installation may trigger wrinkling of the corrosion resistant liner. Technip have undertaken a development programme in accordance with DNV-RP-A203 to design and qualify mechanically lined pipes for reeling without the use of internal pressure. The proposed novel design enables a safe and reliable reeled installation and a subsequent lifetime operation of mechanically lined pipes by controlling the liner thickness.

Steel Layer

According to ANSYS software and an electron probe experiment, a multi-layer finite element model (FEM) of pulsed laser bending of stainless steel-carbon steel laminated plate (SCLP) including interfaces has been established. Compared with a single-layer stainless steel plate (SLSP), based on a temperature gradient mechanism considering the depth of the plastic zone, the influence of the interfaces and carbon steel layer in the model of the SCLP on the bending angle has been studied by analyzing the distributions of the temperature field, stress field and strain field in the thickness direction. The simulation results show that the temperature of the SCLP in the thickness direction is lower than that of the SLSP due to interfacial thermal resistance of the interface and fast heat conduction of the carbon steel layer, resulting in a smaller depth of the plastic zone of the SCLP defined by the recrystallization temperature. Affected by the temperature distribution, the plastic stress and strain of the SCLP in the plastic zone are smaller than those of the SLSP, leading to a smaller bending angle of the SCLP. When the laser power is 140 W, the scanning speed is 400 mm/min, the defocus distance is 10 mm, and the scanning time is 1, the bending angle of the SCLP is 1.336°, which is smaller than the bending angle 1.760° of the SLSP. The experimental verifications show that the maximum error of the bending angle is 3.74%, which verifies that the model of laser bending is usable and contributes to refining the laser bending mechanism of the SCLP.
