上海方工閥門制造有限公司,主要介紹國內外工業(yè)管道及閥門的現(xiàn)狀與發(fā)展;工業(yè)管道及閥門維修、安裝必備的基本知識;管道布置和常用竹材、管件及附件;介紹管通和閥門的修理及安裝;管道的試壓與防腐保溫;管道故障及維護。附錄還介紹管路系統(tǒng)圖形符號和圖例。
本書可供管道、閥門機械設備維修人員和廣大工程技術人員參考使用。

5)安全閥使用單位應向供貨單位(制造廠)提出安全閥的明確訂貨要求,并在收貨時索要相關文件(例如合格證、質量證明書、試驗報告等)以及進行必要項目的驗收。

第 2 章 工業(yè)管道及閥門維修、安裝必備的基礎知識

2-1 管道有哪些分類方法?管道有什么用途?

答:管道分類方法通常按介質的壓力、溫度、性質分類,也可按管道材質、溫度和壓力分類,以及材質情況等分類方法。

這里管道按其材質可分為鋼管、有色金屬管、鑄鐵管、非金屬管四種。他們的主要用途例舉如下:

(1)鋼管

1)一般無縫鋼管、用于制作流體介質管道或制作結構管件等。標準為 GB/T 8163—1999《輸送流體用無縫鋼管》。常用規(guī)格:結構用無縫鋼管外徑 5~200,壁厚 0.25~14mm,見表 2-1;輸送流體用無縫鋼管外徑 32~630mm。壁厚 2.5~75mm,見表 2-2。

常用無縫鋼管規(guī)格尺寸及單位長度理論質量(kg/m)見表 2-3。
