1·That can include beams, posts, drain lines, water piping or surface-mounted wires.

包括横梁、柱子、排水管道、供水管道或表面贴装线。

2·One of the effective solutions to suppress the noise radiation is to install a silencer in the water piping system.

在水管路系统中，安装水消声器是降低管路系统辐射噪声有效方法之一。

3·If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation.

如果室内安装区域可能出现冰冻温度，则水管线必须加装保温层保护。

4·Fluid pressure pulse is one of the main noise source in water piping system, mufflers are widely used to restrain pressure pulse.

在海水管道系统中，由泵、阀门、弯头等元件引起的压力脉动(即流噪声)是主要的噪声源，消声器被广泛应用于抑制流体压力脉动。

5·Select a location near the center of the water piping system. It must be installed indoors and in a vertical position on a level surface.

选择靠近水管系统中心的位置。必须在室内的水平地面上立式安装。

6·Select ta location near the center of the water piping system. It must be installed indoors and in a vertical position on a level surface.

选择靠近水管系统中心的位置。必须在室内的水平地面上立式安装。

7·The security influence of the flushing pipe parameter and the flushing pipe system on-position for steam-water piping system are analyzed.

分析了冲管参数和冲管系统接入位置对汽水管道系统的安全性影响。

8·IMPORTANT: Removal and replacement of the heating element involves the disconnection of water piping connections and electrical connections.

重要：加热元件的拆卸和更换涉及到水管的拆卸和电路连接的断开。

9·The fluid pressure pulse and flow-noise in water piping system decreased the operation safety of piping system and hiding ability of submarines.

水管路系统流体压力脉动及其引起的流噪声会降低管路系统自身工作的可靠性和舰船的隐蔽性。

10·This paper introduces the layout plan, selection of design data and main design steps of rain water piping system of large and medium-scale plants.

介绍大中型企业厂区雨水管道系统的平面布置、设计数据的选取和主要的设计步骤。
