根据CCS共同规范及ABS 规范，还有IMO Resolution A.753(18) - Guidelines for the Application of Plastic Pipes on Ships - (adopted on 4 November 1993) - Annex - Guidelines for the Application of Plastic Pipes on Ships - 4 Installation 的要求，楼主看下关于管子支架的回答，希望对你能有用：
CCS 规范：3-2、1.6.1
1.6.1 支架
(1) 船上系统中管架的选择和间距应取决于许用应力和最大挠度。支架之间的距离应不大于管子
制造厂所推荐的距离。选择管架和间距应考虑管子尺寸、管材的机械和物理性能、管子和管内液体的
质量以及该系统可能遇到的外压、工作温度、热膨胀影响、外力引起的负荷、冲击力、水锤现象、振动、
系统能经受流体流动的最大加速度, 并应考虑到综合负荷。
(2) 每一支架的全宽范围上应均匀承担管子及其内部介质的荷重。管子与支架相接触时, 应采取
措施以减小管子磨损。
(3) 管系中的重部件, 如阀和膨胀接头应作单独支撑。
ABS 规范 4-6-3/7.1
Supports
7.1.1 Spacing
Selection and spacing of pipe supports in shipboard systems are to be determined as a function of
allowable stresses and maximum deflection criteria. Support spacing is not to be greater than the
pipe manufacturer’s recommended spacing. The selection and spacing of pipe supports are to take
into account pipe dimensions, mechanical and physical properties of the pipe material, mass of
pipe and contained fluid, external pressure, operating temperature, thermal expansion effects,
loads due to external forces, thrust forces, water hammer and vibrations to which the system may
be subjected. Combinations of these loads are to be checked.
IMO 要求：
4 Installation
4.1 Supports
4.1.1. Selection and spacing of pipe supports in shipboard systems should be determined as a function of allowable stresses and maximum deflection criteria. Support spacing should be not greater than the pipe manufacturer’s recommended spacing. The selection and spacing of pipe supports should take into account pipe dimensions, mechanical and physical properties of the pipe material, mass of pipe and contained fluid, external pressure, operating temperature, thermal expansion effects, loads due to external forces, thrust forces, water hammer, vibration, maximum accelerations to which the system may be subjected, and the type of support. The support spans should also be checked for combinations of loads.
4.1.2. Each support should evenly distribute the load of the pipe and its contents over the full width of the support and be designed to minimize wear and abrasion.
4.1.3. Heavy components in the piping system such as valves and expansion joints should be independently supported
