“PVRC压力容器研究解释报告”的这一部分涵盖了制造和环境条件对压力容器性能的影响。首先考虑的是成型操作。单曲率形状的成形在轧辊或压力机中进行，而双曲率形状的成形在压力机或旋压设备中进行。对于这两种形状，成型温度取决于材料、厚度、半径、热处理、强度、延展性和设备限制。

This section of the "PVRC lnterpretive Report of Pressure Vessel Research" covers the effects of fabrication and environmental conditions on pressure vessel behavior. The first item considered is forming operations. Forming of single-curvature shapes is conducted in rolls or presses, whereas forming of double-curvature shapes is conducted in presses or spinning equipment. For both shapes, forming temperature depends on material, thickness, radius, heat treatment, strength, ductility, and equipment limitations.
