Discussion of anodically protected shell and tube strong acid stainless steel cooler and its being made domestically 浅议带阳极保护管壳式不锈钢浓酸冷却器及其国产化
Ceramic thermal resistance are mainly composed of sensingelement , protective tube , connection head and fixed device forinstallation etc 套保护管接线盒及安装固定装置等主要部件组成。
The structure characteristic sand control is in charge of being protected tube , base managing , internal and external network , filtering 结构特点防砂管由保护管基管内外网过滤层等组成。
5 . allowed working pressure of thermal resistance commonly means static outer pressure beared by protective tube in working temperature 一般指在该工作温度下保护管所能承受的外压静态而不破裂。
2 . protective tube is manufactured from alloy material with standing wear - proof and souring - resistant at high temperature as well polished 2保护管采用高温耐磨高温下抗冲刷合金材料，并进行光洁处理。
Used to protect pipe wall and not affect the water quality . there is no need to install complicated chemical releasing machines or water quality control systems 用于保护管壁而非改变水质，不需设置繁杂的加药控制器及水质控制系统。
Objective : to determine the efficacy of a new intracolonic bypass tube ( icbt ) designed for a one - stage procedure for left colonic obstruction 摘要本院大肠直肠外科自行设计一种新式的肠内保护管，是结合可分解式肠道吻合环与保险套的长而软的保护内管。
Industrial - use metallic thermometers , thermocouples , resistance thermometer bulbs , heavy electrical - use protection equipment , pressure meters , protecting tubes and related equipment 工业用金属温度计热电偶测温电阻体重型电机用保护机器压力表保护管及相关机器。
Initiated in early 1993 , we start to produce tct protecting tube for pealtech company of usa in 1994 with a yearly production about 1 thousand tons 公司始建于一九九三年初，一九九四年开始为美国皮尔太克公司定点生产热电偶（ thermocoupleprotectiontubes ）保护管，年产量近千吨。
Results : in all four patients who underwent intracolonic bypass , the obstruction was relieved , the tube was spontaneously expelled , and there was no post - operative morbidity or mortality 术后追踪，肠内保护管因为吻合环的可分解特性，均于手术后三周左右自行分离成碎片而由肛门随粪便排出，并没有吻合?漏并发症，亦无死亡病例。
