<p> 屈服點(diǎn)（σs） </p> <p> 具有屈服現(xiàn)象的金屬材料，試樣在拉伸過程中力不增加（保持恒定）仍能繼續(xù)伸長(zhǎng)時(shí)的應(yīng)力，稱屈服點(diǎn)。若力發(fā)生下降時(shí)，則應(yīng)區(qū)分上、下屈服點(diǎn)。屈服點(diǎn)的單位為N/mm2（MPa）。 </p> <p> 上屈服點(diǎn)（σsu）：試樣發(fā)生屈服而力第壹次下降前的比較大應(yīng)力；下屈服點(diǎn)（σsl）：當(dāng)不計(jì)初始瞬時(shí)效應(yīng)時(shí)，屈服階段中的小應(yīng)力。 </p> <p> 屈服點(diǎn)的計(jì)算公式為： </p> <p> 式中：Fs--試樣拉伸過程中屈服力（恒定），N（牛頓）So--試樣原始橫截面積，mm2。 </p><p> 鍍鋅圓管是按內(nèi)徑還是外徑計(jì)算價(jià)格呢？公稱直徑,有別于外徑和內(nèi)徑 ,是一種大家認(rèn)可的叫法,通過其可以很好的去找到相應(yīng)的外徑和壁厚,只要其公稱直徑相同,就可用相同公稱直徑的管件相連接,具有通用性和互換性。一般來說，管子的直徑可分為外徑、內(nèi)徑、公稱直徑。管材為無縫鋼管的管子的外徑用字母D來表示，其后附加外直徑的尺寸和壁厚，例如外徑為108的無縫鋼管，壁厚為5MM，用D108*5表示。 </p> <p> 塑料管也用外徑表示，如De63,其他如鋼筋混凝土管、鑄鐵管、鍍鋅鋼管等采用DN表示，在設(shè)計(jì)圖紙中一般采用公稱直徑來表示，公稱直徑是為了設(shè)計(jì)制造和維修的方便人為地規(guī)定的一種標(biāo)準(zhǔn)，也叫公稱通徑，是管子（或者管件）的規(guī)格名稱。 </p> <p> 標(biāo)準(zhǔn)中稱此外徑與厚度為公稱外徑與公稱厚度。輸送流體用無縫鋼管和一般用途無縫鋼管分熱軋管和冷拔管兩種。冷拔管的外徑為200mm；熱軋管的外徑為630mm。 </p> <p> 在管道工程中，管徑過57mm時(shí)，常采用熱軋管。管徑在57mm以內(nèi)常選用冷拔管。DN2000鞍座是指支承DN2000mm容器的鞍式支座。還有一些零部件的公稱直徑是與它相配的管子公稱直徑表示的。如管法蘭，DN200管法蘭是指連接DN200mm管子的管法蘭。昆明鍍鋅圓管廠家報(bào)價(jià)，云南贛僑貿(mào)易供應(yīng)。</p><div
