分配系统—洁净管道工程概述
Distribution system-an overview of clean pipeline project
在药厂中有大量的工艺过程涉及到分配系统。如：纯化水的分配系统，注射水的分配系统，药液在配置容器之间的传输和分配等等。
惠源公司了解这些系统的通行惯例和特殊要求，为客户提供工艺容器的设计、制造、安装、测试及验证支持服务。
根据生物工程设备的特殊要求，洁净管道工程应有良好的结构，满足制药学、卫生学的要求。一个好的管路系统应在以下方面充分考虑：
材料的化学稳定性——无溶出。无毒、不脱落材料制造。常用304和316L不锈钢。
表面处理——与介质相接处的表面通常需要作机械或化学抛光处理。
连接方式——以采用氩气保护自动轨迹焊接为主，在有方便拆装要求的地方，采用卫生快开连接。
合理的管径——管径的选择在实质上是选择适当的流速，防止微生物在管壁停留和附着、滋生。
倾斜度——利于排空，使溶液能依靠自身重力排净，同时应避免出现多处低点。
接附件、阀门处限制长径比——防止出现长盲管端，阻止微生物在此生长。
温度——在某些温度范围内，可以有效防止微生物滋生。例如国际通行的方法：注射用水在80℃以上保温或65℃以上循环保温。
采样点、检测点——合理设置在线检测点，采样点，可以满足在系统投入运行后的维护、验证的需要。
保温——防止烫伤、冻伤、结霜，节约能源。在卫生等级房间穿过的管道保温还需要考虑密封，以防止不同卫生等级房间之间空气的流通。
正确安装附件——对各种附件有*准确的了解，正确安装。



Distribution system - clean Pipeline Project Overview
Distribution system-an overview of clean pipeline project
There are a large number of processes in the pharmaceutical companies involved in the distribution system. Such as: the purified water distribution system, the distribution system of the injection water, the liquid in the configuration container between transmission and distribution and so on.
The Huiyuan understａnd a common practice and the special requirements of these systems, providing customers with process vessel design, manufacturing, installation, testing and validation support services.
According to the special requirements of the bio-engineering equipment, clean pipeline project should have a good structure to meet the requirements of the pharmaceutical, hygiene. A good pipeline system should take full account of the following areas:
The chemical stability of the material - no dissolution. Non-toxic, non-shedding material. Commonly used 304 and 316L stainless steel.
The surface treatment - usually with the surface of the dielectric at the junction of the need for mechanical or chemical polishing treatment.
Connection - using the the argon protection automatically trajectory welding mainly in convenient disassembly required, the use of the health fast open connection.
Reasonable diameter - the choice of diameter in essence is to select the appropriate flow rate to prevent microbial stay in the wall and attached breeding.
Inclination - conducive emptying of the solution to be able to rely on their own gravity drain, and should avoid multiple low.
Annex valve at the limit aspect ratio - to prevent a long blind pipe end to stop the growth of microorganisms in this.
Temperature - within a certain temperature range, can effectively prevent microbial growth. Such as international methods: injection water kept above 80 ℃ or above 65 ℃ loop insulation.
Sampling point detection point - a reasonable set of online detection point, the sampling points, maintenance, verification of the need to meet the operational system.
Insulation - to prevent burns, frostbite, frost, saving energy. Through the pipe insulation in the Health Level Room also need to consider sealed to prevent the flow of air between the different health level room.
Correct mounting accessories - completely accurate understanding of the various accessories installed correctly.
