class="title">詳細(xì)說(shuō)明</p><div id="h3jnr7t" class="box"><p><p style="text-indent:25px"> 帶頸對(duì)焊法蘭和帶頸平焊法蘭的區(qū)別主要有以下三點(diǎn)： 1、焊縫形式不同：帶頸平焊法蘭管子與法蘭的焊接焊縫形式為角焊縫，而帶頸對(duì)焊法蘭與管子的焊接焊縫形式為環(huán)焊縫; 2、材質(zhì)不同：帶頸平焊法蘭材質(zhì)為厚度符合要求的普通鋼板機(jī)加工而成，而帶頸對(duì)焊法蘭材質(zhì)多為鍛鋼件機(jī)加工而成; 3、公稱(chēng)壓力不同：帶頸平焊法蘭公稱(chēng)壓力為：0.6---4.0MPa的，而帶頸對(duì)焊法蘭公稱(chēng)壓力為：1--25MPa等級(jí)的。 4、還有一點(diǎn)，帶頸對(duì)焊法蘭與接管連接的焊縫屬B類(lèi)縫，帶頸平焊法蘭與接管連接的焊縫屬C類(lèi)縫，焊后無(wú)損檢測(cè)不一樣。 5，江西毛坯鍛件信賴(lài)推薦、帶頸平焊法蘭與帶頸對(duì)焊法蘭不能隨便替換，就制造角度而言帶頸平焊法蘭(SO是SLIP ON縮寫(xiě))內(nèi)經(jīng)大，意味著重量小，江西毛坯鍛件信賴(lài)推薦，成本就低，江西毛坯鍛件信賴(lài)推薦，另外公稱(chēng)直徑大于250mm的帶頸對(duì)焊法蘭(WN是WELDING NECK的縮寫(xiě))要檢測(cè)，SO的法蘭不需要檢測(cè)，所以成本就低了。 </p><div style="width:100%;text-align:

style="text-indent:25px">1、測(cè)量前的準(zhǔn)備工作：a、在測(cè)量前根據(jù)法蘭位置，應(yīng)首先畫(huà)出設(shè)備各連接管法蘭草圖，并連續(xù)編號(hào)，以便夾具對(duì)號(hào)安**、由于安裝時(shí)，法蘭可能存在外徑不一，錯(cuò)口（不同心），墊片厚度不一等情況，所以加工出來(lái)的夾具應(yīng)與所側(cè)法蘭相對(duì)應(yīng)不能互換，因此測(cè)量各部尺寸和編號(hào)是夾具加工及安裝的關(guān)鍵。c、測(cè)量時(shí)，比較好安排三人，其中兩人測(cè)量，一人校對(duì)并填表，測(cè)量工具比較好永游標(biāo)卡尺，若沒(méi)有條件可用外卡鉗和鋼板尺。測(cè)量是一項(xiàng)細(xì)致的工作，是夾具安裝的前提，測(cè)量與記錄一定要準(zhǔn)備無(wú)誤，填表時(shí)一定要認(rèn)真清楚。d、所測(cè)數(shù)據(jù)填于表中。2、法蘭測(cè)量：a、首先分別精確測(cè)量法蘭外徑D1、D2的尺寸，如測(cè)出數(shù)據(jù)為157.5mm則此尺寸為157.5mm.b、測(cè)量法蘭間隙b尺寸，在圓周上測(cè)四點(diǎn)（均布）。c、測(cè)量深度C（法蘭外邊與螺栓之間的尺寸）見(jiàn)圖2的放大部分，在法蘭的1234位置分別測(cè)量C的尺寸，選擇**小的尺寸。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江西毛坯鍛件信賴(lài)推薦"

平焊法蘭分螺紋連接(絲接)法蘭和焊接法蘭。低壓小直徑有絲接法蘭，高壓和低壓大直徑都是使用焊接法蘭，不同壓力的法蘭盤(pán)的厚度和連接螺栓直徑和數(shù)量是不同的。根據(jù)壓力的不同等級(jí)，法蘭墊也有不同材料，從低壓石棉墊、高壓石棉墊到金屬墊都有。法蘭連接使用方便，能夠承受較大的壓力。平焊鋼法蘭:適用于公稱(chēng)壓力不超過(guò)2.5MPa的碳素鋼管道連接.平焊法蘭的密封面可以制成光滑式,凹凸式和榫槽式三種.光滑式平焊法蘭的應(yīng)用量比較大.多用于介質(zhì)條件比較緩和的情況下，如低壓非凈化壓縮空氣、低壓循環(huán)水，它的優(yōu)點(diǎn)是價(jià)格比較便宜。
