1、低壓流體運送用鍍鋅焊接方管，規(guī)范號為GB/T3091-2008.表示原料Q235A,Q235BQ345B等。首要用于運送水、煤氣，金鄉(xiāng)批發(fā)螺紋管廠家、空氣、油和取暖熱水或蒸汽，用處限于一般較低壓力流體。 </p> <p> 2、低壓流體運送用鍍鋅焊接方管，規(guī)范號為GB/T3092-2008.表示原料同上。首要用于運送水、煤氣、空氣、油和取暖熱水或蒸汽等一般較低壓力流體，方管表面選用熱鍍鋅或是冷鍍鋅防腐工藝。 </p> <p> 3、礦用流體運送焊接方管，規(guī)范號我GB/T14291-2000.表示原料Q235A、B級鋼。首要用于礦山壓風、排水、軸放瓦斯用直縫焊接方管。 </p> <p> 4、低壓運送用螺旋方管（石油部規(guī)范）規(guī)范號為SY/T5037-2008，金鄉(xiāng)批發(fā)螺紋管廠家.表示原料為Q235BQ345B等碳鋼原料。首要用于低壓運送水，石油，天然氣，供暖等管道。運送可燃性和非可燃性流體用方管，規(guī)范號為GB/T9711.1（GB/T9711，金鄉(xiāng)批發(fā)螺紋管廠家.2）-1997.表示原料為L245-L415,等管線用鋼。首要用于運送可燃性和非可燃性流體低壓或高壓用方管，要求比較高。 </p> <p> </p> <p> <br /> 鋼塑管的用途有哪些？金鄉(xiāng)批發(fā)螺紋管廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="金鄉(xiāng)批發(fā)螺紋管廠家,管" src="https://tyunfile.71360.com/WaterMark/UploadFile/jngxwz/637262821933593750/9732834.png"></div><p> 鋼管還是各種常規(guī)武器不可缺少的材料，qiang管、炮筒等都要鋼管來制造。鋼管按橫截面積形狀的不同可分為圓管和異型管。由于在周長相等的條件下，圓面積較大，用圓形管可以輸送更多的流體。此外，圓環(huán)截面在承受內部或外部徑向壓力時，受力較均勻，因此，絕大多數(shù)鋼管是圓管。但是，圓管也有一定的局限性，如在受平面彎曲的條件下，圓管就不如方、矩形管抗彎強度大，一些農(nóng)機具骨架、鋼木家具等就常用方、矩形管。根據(jù)不同用途還需有其他截面形狀的異型鋼管。 </p> <p> <br /> 麗水鍍鋅管哪里有鋼塑管的用途很廣，石油、天然氣輸送，工礦用管，飲水管，排水管等都可以見到它的身影。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="金鄉(xiāng)批發(fā)螺紋管廠家,管" src="https://tyunfile.71360.com/WaterMark/UploadFile/jngxwz/637262822974121093/350471.png"></div><p> 按用途 </p> <p> 管道用管。如：水、煤氣管、蒸汽管道用無縫管、石油輸送管、石油天然氣干線用管。農(nóng)業(yè)灌溉用水龍頭帶管和噴灌用管等。 </p> <p> 熱工設備用管。如一般鍋爐用的沸水管、過熱蒸汽管，機車鍋爐用的過熱管、大管、小管、拱磚管以及高溫高壓鍋爐管等。 </p> <p> 機械工業(yè)用管。如航空結構管（圓管、橢圓管、平橢圓管），汽車半軸管、車軸管、汽車拖拉機結構管、拖拉機的油冷卻器用管、農(nóng)機用方形管與矩形管、變壓器用管以及軸承用管等。 </p> <p> 石油地質鉆探用管。如：石油鉆探管、石油鉆桿（方鉆桿與六角鉆桿）、鉆挺、石油油管、石油套管及各種管接頭、地質鉆探管（巖心管、套管、主動鉆桿、鉆挺、按箍及銷接頭等）。 </p> <p> 化學工業(yè)用管。如：石油裂化管，化工設備熱交換器及管道用管、不銹耐酸管、化肥用高壓管以及輸送化工介質用管等。 </p> <p> 其他各部門用管。如：容器用管（高壓氣瓶用管與一般容器管），儀表儀器用管、手表殼用管、注射針頭及其醫(yī)療器械用管等。 </p><p> 鍍鋅鋼管的技術要求 </p> <p> 1、牌號和化學成分 </p> <p> 鍍鋅鋼管用鋼的牌號和化學成分應符合GB/T3092所規(guī)定的黑管用鋼的牌號和化學成分。 </p> <p> 2、制造方法 </p> <p> 黑管的制造方法（爐焊或電焊）由制造廠選擇。鍍鋅采用熱浸鍍鋅法。 </p> <p> 3、螺紋及管接頭 </p> <p> （a）帶螺紋交貨的鍍鋅鋼管，螺紋應在鍍鋅后車制。螺紋應符合YB 822的規(guī)定。 </p> <p> （b）鋼制管接頭應符合YB 238的規(guī)定；可鍛鑄鐵管接頭應符合YB 230的規(guī)定。 </p> <p> 4、力學性能鋼管鍍鋅前的力學性能應符合GB 3092的規(guī)定。 </p> <p> 5、鍍鋅層的均勻性鍍鋅鋼管應作鍍鋅層均勻性的試驗。鋼管試樣在硫酸銅溶液中連續(xù)浸漬5次不得變紅（鍍銅色）。 </p> <p> 6、冷彎曲試驗公稱口徑不大于50mm的鍍鋅鋼管應作冷彎曲試驗。彎曲角度為90°，彎曲半徑為外徑的8倍。試驗時不帶填充物，試樣焊縫處應置于彎曲方向的外側或上部。試驗后，試樣上不應有裂縫及鋅層剝落同象。 </p> <p>
