style="text-indent:25px">隨著我國變革開放政策的施行，國民經濟取得快速增長，城鎮(zhèn)住宅、公共建筑和旅游設備大量興建，對熱水供給和生活用水供應提出了新的請求。特別是水質問題，人們越來越注重，請求也不時進步。2001年不銹鋼銷售額達17.15億元，產量達10.6萬噸。不銹鋼管2.22億元，產量2，11萬噸，上交國度稅金達1億多元。鋼管出口量也逐年增大，2001年為5000T，估計今年出口量為8000~10000T，已有10來家企業(yè)獲得自營進出口權。不銹鋼管遠銷東南亞、歐盟數十個國度和地域，深受國外商家和用戶的贊揚。關于接受流體壓力的鋼管都要停止液壓實驗來檢驗其耐壓才能和質量，在規(guī)則的壓力下不發(fā)作走漏、浸濕或收縮為合格，有些鋼管還要依據規(guī)范或需方請求停止卷邊實驗、擴口實驗、壓扁實驗。</p><p style="text-indent:25px">不銹鋼管普通常用布氏、洛氏、維氏三種硬度指標來權衡其硬度。布氏硬度在不銹鋼管規(guī)范中，布氏硬度用處較廣，常常以壓痕直徑來表示該資料的硬度，既直觀，又便當。但是關于較硬的或較薄的鋼材的鋼管不適用。洛氏硬度不銹鋼管洛氏硬度實驗同布氏硬度實驗一樣，都是壓痕實驗辦法。不同的是，它是丈量壓痕的深度。洛氏硬度實驗是當前應用很廣的辦法，其中HRC在鋼管規(guī)范中運用僅次于布氏硬度HB.洛氏硬度可適用于測定由極軟到極硬的金屬資料，它補償了布氏法的不是，較布氏法煩瑣，可直接從硬度機的表盤讀出硬度值。按鋼管的外徑形狀又可分為圓管和異形管。</p><div
